Summer 2018 Update!

Posted on August 25, 2018 by oceanexplorer

Wow, this summer has been so busy, I’ve been unable to keep you up on all the happenings. I hope yours has had its share of fun too. Before I fill you in on the Atlantic Cup, the two Mac Races and my new involvement with The Chicago Maritime Arts Center, let me catch you up on the progress of my book, Spirit of a Dream.

The road to publication takes a lot of patience, but the wait is nearly over. The first proofs have arrived, and after a few tweaks, we are quite happy with them. Now we are awaiting the arrival of our Library of Congress catalog number. Once we get it, Seaworthy Publishing will push the button, and Spirit of a Dream will be available on Amazon! That could be a week or two, but hopefully no more than a month!

I’m obviously excited about the book’s publication and can’t wait to share the stories with you. Hopefully, the extra time and hard work have been worthwhile, and will provide you with an excellent read. While we await the arrival of Spirit of a Dream, let me fill you in on other great adventures from this summer.

First off, the biennial Atlantic Cup ran in its usual late May, early June time frame. With 11 boats competing from Brazil, France, Norway, South Africa, USA and sailors from other countries far and wide, the racing was exceptional, very competitive and as challenging as offshore racing can get. Through it all, Earendil, sailed by Catherine Pourre and Pietro Luciani held their consistency to take top honors and win the cup. Catherine was the first winning female in the history of the race.

Earendil was followed by Toothface sailed by Mike Dreese and Tristan Mouligne and then by Amhas with the venerable Rob Windsor and Micha Davis trimming to a close third. Oakcliff Racing, my old boat Bodacious Dream, on which we won the Atlantic Cup in 2013 and with which I then circumnavigated the globe in 2014, had a great final race. They pressed the whole way for a top position, showing that Bo is still one fast boat!

For the past two Atlantic Cups, my involvement has chiefly been with managing the AC Kids Education Program. This year, our crew put on the best event so far, sharing the program, the excitement and the wisdom of the sailors and the ocean with over 2000 kids of all ages and backgrounds! While 9-12-year-olds make up the bulk of the students, we were inspired by the inquisitiveness of first and second graders too and by the determination of high school students who were studying marine biology.

As always, we learn as much from the kids as they do from us. One student spoke out in class by saying, “If plastics last 100 years or longer, then all the plastic we’ve ever made is still here on the earth!” That one really gave me pause. Even I had never looked at it quite that way. No matter where or how you disposed of the plastic you’ve used in your life, it continues to live somewhere. Always give plastic a chance to live a new, recycled life.

Here’s the video from the Atlantic Cup Kids Program. Watch it to the end to hear the final, fantastic statement from the young girl. Her sincerity says it all… ”It’s our earth darn it!”

Next up, 11th Hour Racing gave us, its panel of ambassadors. the opportunity to designate a non-profit organization that we felt most closely aligned with and could help expand each of our own interests and efforts. I chose the Chicago Maritime Arts Center, after being introduced to them by my close friends, Phil Pollard and Grant Crowley over at Crowley’s Yacht Yard, on East 95th Street in Chicago.

The CMAC consists of a group of passionate boaters inspired by the founder, Capt. Toby Lindo, who launched the program which works with school-age kids to build and operate small boats and so hopefully stimulate some tangible changes in those kid’s life experience. Through the process of building a simple skiff and launching it on the Chicago River, these kids get the chance to do something not easily available in their inner-city neighborhoods.

I was lucky enough to attend the second session this summer and wow, what a kick! Kids were using drills, handsaws, measuring tapes, paintbrushes and other tools to build a 10-foot-long Bevin’s Skiff. On launch day, they carried the boats to the water’s edge and with a few words of dedication, quickly slipped them into the water, hopped in and took to the oars. The first few uncoordinated swipes with the oars soon turned into proficient sweeps as these strong young kids took charge of the day and hopefully set a new course for their lives.

The leadership of the CMAC is focused on building out their program to provide this opportunity citywide. Gaining valuable wisdom and insights from other programs throughout the country and leveraging local expertise, they have made a great start, and I have every confidence that within a few years, CMAC will be impacting many young adult lives that will ripple positively across their communities. Check them out on Facebook too – they are definitely worthy of your attention and any spare change you might be able to share with them.

Lastly, the Mac Races! These races are the main event in a Great Lakes sailor’s summer. First up this year was the Bayview Mac Race, which began at the southern tip of Lake Huron and ran the length of Lake Huron to Mackinac Island. I raced the 280 some miles with my good friends on Defiance, a JV 67. Light or mostly non-existent winds actually covered the entire racecourse, except for the last 20 miles when a fresh northerly provided beautiful, clear, upwind sail to the finish. We were excited to be the third boat across the finish line, behind Windquest and Wizard, although the handicap correction dropped us further down the rankings. If anyone ever tells you big winds make for hard sailing, tell them that light or no wind is equally as taxing for competitive-minded sailors.

The following weekend, under rainy, grey skies, and a building northerly wind that would stay through the entire race, aboard the good ship Tango in Blue, we started the Chicago Mac Race. This year I got the unique chance to sail with a crew that included my godson, Harry Barrows who, at 18 was getting the chance to sail his first Mac race! If you’ve heard any stories of this year’s Chicago Mac, they’re probably accurate. We pounded along into 20-25 knot upwind conditions for two continuous days until the winds eased a bit and the skies lightened up. Hour after hour of being doused by waves, while hanging on the rail, as the boat heaved and bashed its way into the next wave. Nights of endless blackness, fatigue and shivering in our cold wet skivvies unleashed an endless stream of stories once we reached Mackinac Island.

This story ended happily though with a tired, elated crew as we topped our section in first place. Without that extra boost of adrenaline at the finish line, that first glass of champagne migh have left me horizontal on the dock.

If that wasn’t enough for one summer, on June 30th, I was honored with induction into the Lake Michigan Sail Racing Federation Hall of Fame. Many friends and family gathered for the ceremony at the Michigan City Yacht Club, the place I call my home harbor, to celebrate. After 45 years of sailing, I have quite a collection of plaques and awards, but none of them are as precious as the ones like this one, that come with the respect of my peers. This honor is especially precious.

So, that’s been the summer, and for it, I am one lucky sailor. I hope yours summer has been full of good memories too. With the coming of fall, look for Spirit of a Dream.

A smooth sail to you into whatever adventures fall and winter might bring you.

Regards to all,

Ocean Learning Unbound!

Posted on May 18, 2016 by oceanexplorer

We’re in the thick of it now! With so much to do for the Atlantic Cup Kids program, time has really been flying by quickly. The start of The Atlantic Cup Race is less than 10 days away and our first group of students will be visiting the race village in Charleston, SC a week from now! In Charleston alone, we have scheduled over 500 students to visit the race village and boats! That’s an epic leap forward!

In early May, I visited six schools in Charleston to inspire and to be inspired by hundreds of kids. I talked to 15 different classes over two days! It was great to see how much they already knew about weather, oceans and science – and how insightful their questions for me were.

Carolina Dreamer Project on Display at the Science Fair

One class in particular, Amy McMahon’s, had done something extraordinary. On May 17, 2015, they launched a small unmanned boat named Carolina Dreamer (to the right in the above photo) out across the Atlantic. Each day along the way, the students tracked its progress on satellites, checked the weather along the course and did many of the same calculations I did while sailing Bodacious Dream around the world. At a certain point, they lost contact with the boat, until it was spotted on February 10, 2016 off the coast of Wales, retrieved and sent back to Charleston. Now that was an inspiring tale, which you can read about right HERE!

In response to the enthusiasm and curiosity I’ve encountered around the ocean and boats, I’ve pulled together some thoughts on what is required on the design and budding side that enables racing boats to sail the way they do… with a focus on the physics, chemistry, math and engineering that goes into getting a boat into competitive shape for a race like the Atlantic Cup.

To help me with this, I engaged my friend Merf Owen, a noted naval architect and the designer of two of the boats in the Atlantic Cup to talk about his life and how he came to be a racing yacht designer.

:: Check out the story called “How Boats Sail” as well as “An Interview with Merf Owen – Naval Architect” at their respective links.

A number of the high school students who will visit us in the race village in Brooklyn/NYC and Portland, ME have already expressed their interest in pursuing careers in the marine industry. It’s really an eye-opener when you realize just how many different disciplines are involved in the design, building, maintaining and sailing of modern boats – from engineers and builders to shippers, accountants, business managers and computer specialists. Reading Merf’s interview you’ll see the interesting path he took to becoming one of the best. He also shares what subjects he feels students who want to ready themselves for marine careers should pay closest attention to in school.

So, stay tuned. It will be a busy month ahead! And if you haven’t done so yet, please LIKE our Atlantic Cup Kid’s Page on Facebook. Also check out Carolina Dreamer’s (Educational Passages) Facebook Page and LIKE it for those amazing kids.

Also if you go to the Atlantic Cup Kid’s Page, you can VOTE for your favorite boat and team in this year’s race, where The Atlantic Cup Kids will be presenting the trophy for the Fan Favorite!

More to come! Heading to Charleston early next week!

How Boats Sail!

Posted on May 18, 2016 by oceanexplorer

There are few things more beautiful than the sight of a sleek boat full sail skimming across the water. But how does it all work? How do nature, science and human design come together to enable a sailboat to move in so fluid a way?

From ancient times onward, using wind power to move boats required being tuned into the ways of nature and how its many forces might be harnessed to serve human purposes. To that end, boat builders have always relied on observation and calculation, tradition, testing and passed down refinements to build their boats.

Today though, with all the incredible advances in physics, engineering, computing technology and material science, boat building (and especially racing yacht building) has become a most exciting and cutting edge industry.

To help us get up to speed on boat building today, I asked an old friend of mine, one of the world’s top racing boat naval architects, Merf Owen of Owen Clarke Designs to field some questions about his life designing boats.

You can find my whole interview with Merf RIGHT HERE, but for now, let’s imagine that I asked Merf to design a new Class 40 racer – to say, compete in the Atlantic Cup – a vessel much like the Class40 I sailed around the world a few years ago.

Merf would first want to know how I intend to race the boat and where in the world I plan on sailing it? My answers to these questions help provide him with guidelines for particular factors he will need to consider in designing my boat. When he learns where I want to sail the boat, he will ask a meteorologist (a weather scientist,) to study the weather patterns in those areas and so provide him with weather data (percentages of light, medium or heavier winds and the general wave patterns resulting from them.) Merf will use this information to optimize the design for those regions of the world and for the type of sailing and racing I want to do.

Once Merf has gathered the information he needs, he designs the shape of the hull and the “sail plan.” The hull of course is the “body” of the boat, and the sail plan is the combination of mast and sails and rigging that “power” the boat. He must align his design to the laws of physical science laws in arriving at the best shape for the hull, so that it will move through the water and waves with the least amount of “drag,” to avoid anything that slows a boat down – (like dragging your feet while riding your bike.)

One hundred years ago, a boat designer would carve the model of a boat from a wooden block – using their experience and creative instincts to determine the best shape of the hull. This model would then be converted into hand-drawn blueprints. Today, computers automate much of this process, but Merf still must exercise his intuitions and creativity to course-correct the computer output he receives.

As Merf progresses with his design of the hull shape and sail plan, he can test his work using powerful computer simulation software, which shows him where modifications might help to improve performance. When he’s happy with the design, Merf emails his digital designs to the builder and the fun of boat building can commence!

OCD_Class_40_Deck_P2

Once the builder reviews the design drawings, there’s much that needs to happen. You can just imagine the many things they have to figure out, and how many of them require a solid understanding of mathematics.

How much space do they need in their shop to build the boat and parts? How many layers of fiberglass cloth will be needed? How many gallons of epoxy resin? How many screws? How many people will they need to hire? How long will it take? How much is it going to cost? All of this is must be carefully figured out in order to develop a solid project plan that includes realistic cost estimates.

Once the build plan is in place, more advanced math or “engineering” phase comes into play. First the builders have to build molds in which the boat parts are cast. These molds have to be engineered strong enough to withstand people moving them around and walking on them as the boat is being built. While science, math and engineering are requirements for getting all of this correct, seasoned builders also rely on practical or “seat of the pants” engineering to build the best and strongest molds.

Once building begins, technical engineering drives the process. Structural engineers and designers figure out the details of the composite structure – the number of layers of fiberglass cloth that offer the strength to handle the “loads” (weight and forces) that various parts of the boat must support.

Here again, an understanding of physics is necessary. A rope or “line” turning through a block is a good example. The line pulls a lot of weight and when it turns around a pulley, it changes the direction of the load. The pulley has to withstand these loads and not break loose from its mounting. All these loads and attendant forces have to be calculated so that the size of the block, bolts and composite materials can withstand these always changing loads.

halyard_200 An even more complex set of calculations is necessary when it comes to the mast, which must support the power of the sails through the supporting cables called “shrouds.” There are many calculations to consider in how the shrouds spread the loads across the entire hull. All this has to be worked out so the boat and mast won’t fail in a powerful storm, yet still remain light enough to be competitive on the racecourse. There are always trade-offs to consider between strength and weight when making these important calculations and decisions.

Once construction of the hull begins, workers lay the layers of fiberglass cloth in the mold and then a lightweight core of balsa wood followed by additional layers of cloth to meet the stated engineering requirements. A layer of plastic is then laid over the mold and the edges sealed, at which point a vacuum pump sucks all the air out of the mold. This forces the materials together tightly as an injection system pumps epoxy resin into the mold, filling in the voids and soaking the cloth.

resin

In a few hours, the chemical reaction of the liquid epoxy hardens, creating the strong, hard shell of the boat. To further strengthen the epoxy, the whole boat is put into a large oven and “cooked” at a specific temperature for a period of time. Chemical engineers figure out the specific formulations of the epoxy resins, the temperatures they work at and the time it takes them to harden.

The mast and sails require similar engineering and science know-how. Sails are designed to work like the wings of an airplane – only vertically instead of horizontally. Most people think the wind just blows a boat along, but this isn’t exactly correct. It is the shape of the sails that produces power by allowing the wind to flow along the cloth thus creating pressure differences, which actually “pull” the boat toward the wind. Nowadays, the sails are made from composite plastics and the engineering of their strength and flexibility so that they can bend with the forces of the wind and sails and not break. The mast itself is made in a similar way as the hull of the boat, with cloth and epoxy resins.

Bodacious Dream When the body of the boat is complete, the real fun can begin. The mast and boom, the sails and the rigging are mounted and the boat is launched. Finally, it’s time to take it test sailing to see how the sailplan and the rest of the boat work together.

Once on the water, powerful onboard computers receive signals from multiple sensor devices that monitor everything from the angle and speed of the wind to the shape of the sails and the speed of the boat. These numbers are compared with computer-generated models to determine how well the boat is performing. Even with all this technical help though, the human sailor still must make the strategic refinements necessary for the boat to outpace its competitors and win a race.

An experienced sailor today must master many skills. They must be conversant in many subjects before they can compete in a race like the Atlantic Cup. They need to have learned meteorology and how to anticipate changes in wind directions and speeds. They need enough knowledge of oceanography so that they can track currents and tides and how they dynamically shift and flow around a harbor or coast. They must have also learned how to work with computers so they can program, interpret and manage all the information the computers are capable of providing. And of course they must know their math and engineering, so they can keep the boat moving safely. Some good handyperson skills come in real handy too when called upon to fix things that break in the middle of a race (or when far from land.)

Bringing a boat into existence takes the work of many people with many different skills. Designers like Merf lead teams of skilled engineers, scientists and builders who all take pride in the building of fast and beautiful boats. And finally, there are the sailors, who use their wide range of technological skills and sailing instincts to help them win races like the Atlantic Cup.

Next time you hear your teachers (or parents) talk about the importance of STEM (Science, Technology, Engineering and Mathematics) education – you will be able to relate that to how it applies to the artful science of boat building.

SCIENCE: Weather science, chemical science, computer science, human physiology science
TECHNOLOGY: Computers, monitoring instruments, sail designs and shapes
ENGINERERING: Computers, composites, hardware, pulleys, loads, masts, sails and building
MATHEMATICS: Lots and lots of math. Numbers, computer calculations, engineering load calculations, speed calculations, parts and construction time calculations, cost and business calculations. Endless Math! (The more math you’re able to do in your head, the easier it will be to make these decisions.)

An Interview with Merf Owen, Naval Architect

Posted on May 18, 2016 by oceanexplorer

Dave Rearick of Atlantic Cup Kids interviews Merf Owen, Sailor, Naval Architect and Yacht Designer and principal of Owen/Clark Design, LLC.

Dave Rearick (DR): How old are you now Owen, and when did you get interested in sailing?

Merf Owen (MO): I’m 53 and I first started sailing with a sail training organization called the Ocean Youth Club, when I was 16. I was brought up in the middle of England, far from the sea, but before I left school I had decided I would join the Navy, but I’d never been to sea really. So, I thought I had better do some sailing. My first few days at sea were spent in a very famous storm (in Europe) during the Fastnet Race of 1979.

DR: Where is your home office?

MO: I live in Hamble in England, but my company’s office is three hours away in Dartmouth and we also have an office in New Zealand. The Internet is what helps us to all be able to work together and share a working environment and communicate over thousands of miles and many different time zones.

DR: Your work has you travelling and sailing all around the world, how much do you travel?

MO: I spend a lot of time on the West Coast and East Coast of the United States for business and pleasure. In one year I am only in Hamble perhaps 6 months maximum. The rest of the time I’m in the US, Europe and Australia meeting clients, sailing or going to boatyards/conferences etc.

DR: Do you remember a moment in your life where you got your first big sailing break? The first chance to crew on a hot racer, a meeting with a famous sailor or something like that? Can you tell just a bit about how it inspired you?

MO: The first break was sailing with the Ocean Youth Club… it changed my life. My first big break racing was sailing as navigator on the 85’ catamaran Novell Network with an English skipper called Peter Phillips. We took part in the Round Europe Race in 1985. I was twenty two… and inspired by sailing alongside some of the greatest sailors of their generation… Robin Knox Johnston, Phillip Poupon, Serge Madec, Tony Bullimore…. also Peter Phillips himself, who almost won (but came third in the end) in the 1980 Single-handed Transatlantic Race from Plymouth England to Newport RI. He was beaten by Frenchman Phillip Poupon. It was very special to be around these guys on the dock. I thought after this I would be a professional sailor… but I had to make a choice between careers and I chose design and engineering.

DR: I know you sailed the predecessor to the Volvo Ocean Race…

MO: No, I was a skipper on the BT Global Challenge 1996/97, at the time called the Whitbread Race.

DR: What boat did you sail and how did you get the chance to compete in the Whitbread?

MO: My boat was Global Teamwork. I got the chance by applying for the position of skipper with race organiser Sir Chay Blyth, who I knew from my days multihull sailing. Chay had won the double-handed transatlantic race and was the first man to row the Atlantic Ocean. I applied for the job by an email using satellite communication, the same day as I rounded Cape Horn for the first time with another old friend of mine I met racing multihulls. Alan Wyn Thomas. I’m a strong believer that a sailing life and life in general is about meeting people, being stroked by them and stroking others in return. I am from the middle of England, far from the sea, no one in my family sailed and my father was a train driver. I was lucky with the people I met, but I also made the effort to go out and meet people. I think this is important for young people to know: There are a lot of good people out there who will and can help, but you need to go out and not be afraid to ask, get dirty, start at the bottom, and work hard for what you want… that’s the American way too isn’t it?

DR: When did you get interested in Yacht Design and what course of study did you pursue to become a yacht designer?

MO: I left the Navy and put myself through college… to study naval architecture (submarine design actually) with Royal Corps Naval Constructors at University College London. It was during this time, sailing and racing other people’s boats that I began to gain confidence and begin to think that I could design something better than the boats I was sailing.

DR: Are there particular classes a young student should pay particular attention to if they want to pursue yacht design and engineering?

MO: Maths, Physics, computer studies… but you need to get out on the water too. I would never employ a designer/engineer who either does not sail or has not worked as a boat-builder. Yacht design is not just a theoretical engineering subject. One needs passion and the two most passionate types of people I know are boat builders and sailors. Even if you’re not a great engineer/mathematician, there can be a place for you in a yacht design office if you’ve other skills.

DR: In the years you’ve been designing, can you talk us through a simple history of the changes you’ve seen?

MO:I think the students will find it interesting how far technology has come in the 30 years since I started designing boats at the beginning of the commercial computer age. Although my business partner has ‘drawn’ boats I never have. I used an early Apple computer…an SE to produce the geometry, the line drawings, using an early version of the MaxSurf software that we still use.

Engineering was undertaken with Lamanal Software using a Sirius computer I bought from a company called SP. It was very advanced at the time and cost a lot of money. It used actual Floppy discs – 5.25 inch which could hold 600 KB of information. Amazing eh? Jumping forward thirty years and my laptop is many times more powerful than the Cray super-computer I used at University to develop software in Fortran 77. Nowadays the performance orientated yacht designer’s armory of hardware and software on our laptops is comprehensive. We have the ability to model using computational fluid dynamics, weather, performance analysis and engineering that only an America’s Cup team would have had even ten years ago.

DR: How many Class 40 designs have you done and how many of your designs are in the Atlantic Cup this year?

MO: We have just signed a contract on our sixteenth Class 40 that will be built in South Africa. In the Atlantic Cup this year we have two of our boats racing… Dragon, one of our oldest boats, built in 2008 and Longbow, which is a new boat built last year in Rhode Island.

DR: Longbow is your most recent Class 40 design. You designed it specifically for the Atlantic Cup. In simple terms a person without detailed knowledge would notice, what makes it different?

MO: Class 40 began in Europe where the target races are mainly Trans-Atlantic from East to West. Racing sailboats rely on wind to power them. How fast they go, depends on how they perform changes with the different speeds and angles to the wind that they sail. If you sail across the Atlantic from West to East, instead of from West to East, then it’s possible to design a different kind of boat, one that is faster in those winds. Also, on average in the ocean, in the middle of the Atlantic the wind is stronger than it is on the east coast of the United States. Since all the Class 40s designed and built in Europe were designed for the Atlantic Races, we thought it would be a good idea to design Longbow just for the races it will do on the East coast of the USA. The owner of Longbow just wants to race in America, not across the Atlantic… so the boat is specifically designed for the local conditions. It is faster in the light winds that are a feature of sailing in the summer along the Eastern Seaboard between Charleston and Portland.

DR: What do you think makes a boat a good design?

MO: All good sailing boats are easy to sail, hold their direction when sailing with the minimum of input from the sailor/helmsman. We also like our boats to be “pretty”, although beauty is different in the eye of different people. We often use the following phrases when talking with clients/boat builders/journalists. These are phrases that are well-known to describe design, and we are not the first to use them:

“Function follows form…. which means if it looks right, it ‘probably’ is right.”

At the same time as the above, we’re engineers/technicians as well so we also believe that those who fall in love with practice but without science are like a sailor who steers a ship without a helm or compass, and who never can be certain whither they are going. And the great Nat Hereshoff invented a word when he urged designers to: “Simplicate and add lightness.”

DR: Why do the Class 40’s have two rudders when other boats only have one?

MO: Class 40s are so wide that when they heel over in the wind, if they had only one rudder in the middle it would come out of the water and make the boat impossible to steer.

DR: Most people will notice these boats are very wide, what is the reason for this?

MO: Most racing sailboats historically have been designed to a rule that limits the width of the boat and also the performance. Class 40 comes from a genre of design which has a history of unrestricted rule… it’s called “Open Class.” Wider, in general, is faster… so long as there’s enough wind to match the sailplan of the boat and keep it ‘powering along.’

DR: Are the boats considered light for their size?

MO: Yes, they are… not super light because the rule limits their construction to glass fibre… to save cost. They could be lighter if they were built from carbon fibre… nevertheless, compared to your average sailboat, they are light.

DR: How fast can the Class 40’s go?

MO: I have sailed at 22 knots, but I know boats in certain conditions have sailed at 25 knots and even 30 knots… which is 29-35 mph.

DR: What has been the most exciting project you have worked on designing boats?

MO: So many exciting projects and not all of them racing boats… it’s hard to pick one because they’re all exciting and often for different reasons. People you work with also add excitement, as well as the kind of boat. At the moment, we’re working on a high -latitude cruising boat that will visit the Antarctic and the Arctic and it’s built out of aluminium, not carbon fibre. It’s a very exciting project. Of course, my first boat… a 35’ racing trimaran was an amazing project. I’m still best of friends with the three people who helped me build that boat and one of them is my business partner. Kingfisher, our first Open 60 was designed and built in New Zealand for a young girl… Dame Ellen MacArthur (from the middle of England, much like myself). That was an amazing project, both because of the technology and the people. Our eight and most recent Open 60, Acciona was the first racing boat of its type to circumnavigate the Globe without having any carbon/fossil fuels onboard… just solar and water-generated energy… a cool project. And let’s not forget Longbow… a great project, working with good people and a great owner to create a very special and innovative sailboat. It was fun too building her right here in the United States.

DR: I’m sure the computer and CAD drawing has changed your work… what exciting technologies do you hope these young students watching the Atlantic Cup will develop to make the job of yacht designing even easier and boats even better?

MO: 3D printing is beginning to make a difference in how we present projects to a client. Five years ago we were able to use it, at great cost, to show a client what a 40m cruising boat would look like. Today a workable size printer sells for $3000, and we’re just about to buy one for the office. In the future I’m sure we’ll be able to walk clients though a holographic image of a design, either in our office, at the boatyard or at their home. I hope this happens before I retire!

DR: Thanks so much Merf!

How Boats Sail!

An Interview with Merf Owen, Naval Architect
