Wooden boatbuilding expert Greg Rossel and maritime historian Ben Fuller will discuss the experience of constructing a replica of a Thomas Fleming Day pulling boat at Second Thursdays at The Apprenticeshop, a monthly series on boatbuilding and seamanship for the public.

In 2008, the two men combined their knowledge and skill to interpret the lines of one of only two specimens still in existence. Using an exhibit from the Penobscot Marine Museum, the two studied the vessel and based their lofting on its lines.

“A boat like this hasn’t been built in 90 or 100 years,” Rossel said. “There are no plans. You have to take careful lines and study the forensic evidence if you want to make a replica and really see how it would perform.”

On Thursday, April 8 at 7 p.m., they will bring the finished product to The Apprenticeshop and discuss the process, the boat’s history, and Thomas Day himself. Day came to prominence in the yachting world in 1890 as founder and editor of the internationally circulated magazine The Rudder. He was co-creator of several popular yacht races, including the Bermuda, Marblehead and Havana races.

Rossel began his boatbuilding teaching career in the early 1980s at Maine Maritime Museum’s apprentice school in Bath. His career has included the publication of two must-haves in the wooden boat building industry: “Building Small Boats” and “The Boatbuilder’s Apprentice.” He continues to share his knowledge at The Wooden Boat School in Brooklin.

Fuller has been professionally involved with maritime museums since the early 1970s, serving as the curator of the Chesapeake Bay Maritime Museum and the Mystic Seaport Museum, as well as a stint as a freelance curator. He currently curates the Penobscot Marine Museum. He also is a kayaking enthusiast, holding a Master Maine sea kayak guide license and instructing open water sea kayaking.

The lecture will be held at The Apprenticeshop, a school for traditional boatbuilding and seamanship, located at 643 Main St. in Rockland. Tickets are $5 at the door and benefit the school’s programs. A tour of current projects in the shop will be available after the lecture. Boats under construction include an Abeking and Rasmussen tender, Mermaid sloop, Whitehall tender, and six Susan skiffs. Also under way are two restorations, including a Haj sloop and a Peapod tender. For more information visit apprenticeshop.org.
