The Sheer Artistry of Custom Boatbuilding
By Leigh Pressley

Hand-building wooden boats dates back centuries, but now a Morehead City company is blending the traditional craft with cutting-edge computer technology.

Shearline Boatworks, owned by Mason Cox III and Chip King, builds custom center-console Carolina boats using detailed designs generated on computer software and parts cut from a computer-operated router.

“It’s marrying the old with the new,” says King. “Wooden boats are the oldest kind of boats built, but we’re doing it with the latest in computer technology.”

Cox, a Chapel Hill native who has a bachelor’s degree in marine science from UNC-Chapel Hill and a master’s degree in Ocean Science from Duke University, founded Shearline Boatworks three years ago after working at Jarrett Bay and seeing a niche for smaller, luxurious custom boats from 23 to 43 feet. King, who grew up in Greensboro and has a business background, joined Shearline earlier this year.

“Everything in Carolina boats had gone larger to 54 feet, 58 feet and 61 feet that cost over $1 million,” says Cox. “Typically smaller boats were scraps left over from bigger boats and were seen as runabouts just for fun. I saw a gap in the marketplace for smaller center console boats 23 feet to 43 feet, built to the same standard and the same fit, finish and quality of larger boats.”

Shearline customers can design every aspect of their boat, including its size, settee placement, center console shape and position, hull color, fuel tank size, number of rods, fish box and drink box placement and materials used in decking and railing.
“It’s totally custom,” says King. It’s all up to the customer’s imagination. There’s no list of standard features and no list of options. It’s like building a custom house. Tell me what you want, and we’ll build it.”

Shearline boats, generally set up for offshore fishing, appeal to customers who don’t need more size and who like the lower price point.

“Our 31-foot boat has a $245,000 base, which is far less than the $1.3 million they’d pay for a 57-foot boat other companies make,” says Cox. “Plus the customer goes through pretty much the same process of starting from scratch and entirely custom building the boat.”

Collaboration between the customers and boat builders is key.

“We start with what they want to do in the boat – do they fish a lot or cruise a lot?” says King. “Do they need twin engines, an air conditioner, a generator and a microwave? We all throw in our ideas; it’s very collaborative. That’s part of the fun and part of the allure.”

 

 
 
A Shearline boat may begin as a sketch on a napkin, but quickly takes a high-tech turn. After the four-to-six-week planning process, data is parleyed into a Pro E computer software design that is analyzed by an engineer to appropriate all the weights and balance the boat perfectly.

“We design every boat in three dimensions, which the customer can see on his own computer,” says Cox. “He can rotate the boat, look at how everything is laid out, even virtually float the boat.”

Then construction begins, continuing the computerized process.

“The computer sends the data to a CNC router, which is a piece of machinery that looks like a five-position knife driven by a computer,” says King. “The router cuts each piece of plywood to the exact shape it needs to be, then we put the bones of the boat cut by the computer together. The boat goes from the customer’s head to our heads to the design engineer to the computer software and to the computer router. There’s no room for human error with this machinery.”

The stations, or lateral cross pieces of the boat cut by the computerized router, complete the CNC Jig, which provides the framework of the cold molded boat. Each plank of the wood hull is hand-shaped, then encapsulated in the West Systems Epoxy and hand laid cloth to leave no wood exposed and every surface coated.

Workers then hand-sand the boat to its finish surface, utilizing AwlGrip paint products and top coat.

“AwlGrip is the best paint you can buy, “says King. “It’s what Rolls Royce uses on its cars.”

Hand-built construction takes 12 -14 months, depending on the size and complexity of the boat. Shearline – a play-on-words on the nautical term sheer line, the line that goes up and around the bow of the boat – builds about three boats a year and is currently on hull No. 14.

“Carolina boats have a long tradition of craftsmanship, but have always been built by trial and error, with a pencil and with the knowledge of what worked best in the water” says Cox. “Without this computer software, it would have taken us years of try it and fix it, try it and fix it. Now we can utilize the same software and design capabilities that high end production companies with a lot of resources use.”

So far, all of Shearline Boatworks’ customers have been men, mostly professionals from North Carolina, but that doesn’t mean that all Shearline’s are built alike. “This boat is totally custom-tailored to you. It’s your boat,” says King. “All of them are different, and nobody has one like yours.”
