The first challenge was building the tables that were to act as building floors for our CNC machined foam ama plug, which is pictured above. The next parts tackled were the beams molds and the main hull tool.

Meet the ACC11 Build Team
Dave Walworth
The Naval Architect of the PT-11 is Dave Walworth.
Dave grew up in the 70s in Fort Worth, Texas. He attended St. Johns College where he received a Bachelors in Liberal Arts. After that he taught sailing in Annapolis and built sails in New York. His next stop was Maine at the Landing School where he received a certificate in boat design. This is where Dave and Bill K met in 1988. After his stint in Maine at the Landing School he joined the team at Goetz Custom, where for 5 years Dave and Bill worked building boats and sailing together.
Realizing building may not be his destiny, Dave applied to MIT and was accepted in the Naval Architecture and Marine Engineering Masters program. Dave completed his masters in 1996 all the while living on his 1961 Fairey Marine Atlanta 26 in Boston Harbor. After graduation, Dave went to work for Gold Coast Yachts St. Croix, USVI, as their engineer. Dave still resides in St Croix but now works for himself and possesses his P.E. License. One of his designs, Makani, a 65 foot sailing charter cat doing business in HI, has been clocked at over 26 knots with 50 passengers on board! Visit Dave’s Website for more information about his work.

Kevin Baxley
Kevin is the owner and impetus behind the PT-11. He is involved daily in the decisions behind the construction, design, and outfitting of the 11. Kevin has been lifelong sailor. In his adult years he has been a multi-hull sailor having owned an Atlantic 42 cat and a F-31 tri. His new PT-11 is a big step up in performance and capability. Kevin plans to performance cruise the 11 in New England, campaign her in some Caribbean regattas, and perhaps do some Pacific sailing as well.

At his work he is President and Chief operating officer of the world’s leading supplier of entertainment and event technology – Production Resource Group (PRG). Kevin oversees the day-to-day operations of each of PRG’s offices in the United States, Canada, Japan and the United Kingdom. He joined PRG in 1988 as Vice President of Finance. In the ensuing years, he was also given several important operations roles, including Executive Vice President of scenic operations. In 2000, Kevin was named Chief Financial Officer of PRG, and in early 2003, he was given the responsibility of Chief Operating Officer as well. http://www.prg.com/

Bill Koffler
Bill has also been a lifelong sailor, and has been building hi-tech composite boats for 21 years, including 12 years with Goetz Custom where he served as a “Boat Boss” for 10 years. In his tenure at Goetz Custom, Bill was part of building 7 ACC class yachts, 3 Volvo 60’s, Roy Disney’s west coast sled “Pyewacket,” USA4 and many other cruising and grand prix racing yachts. As the owner of ACC, Bill has successfully built 8 world-class performance cruising boats, with the PT-11 Trimaran being number 9 in its 9 year history. ACC has become a recognized leader in custom built hi-tech performance boats.

PT-11 Project


Date posted: November 1, 2009

Welcome to The PT-11 project. The intention of our blog is to share information about the PT-11 trimaran project and describe its construction. We also want to describe and demonstrate the quality of our build, tout the merits of the PT-11’s design, and ultimately sell some trimarans.

Design Criterion:
The PT-11 trimaran is purposed to be a hi-performance, de-mountable cruising tri. This requires high-quality construction with a great attention to detail. This tri has to be designed for coastal cruising as well as ocean passages. It needs to be fun to sail i.e. powerful, but at the same time easily managed by a small crew (2 people). In addition”
• The sails need to be easily stowed and hoisted.
• The interior needs to be comfortable, sleep 4 adults with a good working galley.
• The head only needs to be functional with enough room to use the head and stand up to shower.
• The cockpit should be roomy enough for 4 people to comfortably sail in.
• The boat should have an inboard that will provide heat for water and power for the electrical system while comfortably pushing her at 8 knots for a 150-mile range.

Additionally:
• The machinery must be easily accessed for maintenance and repair.
• The electrical system must be well engineered for good battery life and easy operation.
• The electronic package will be simple, but a dependable below deck autopilot must be installed.
• The boat should be tiller steered with the ability to steer from outboard on the amas.
Above all, the PT-11 needs to be engineered and built to withstand the rigors of offshore sailing, and look great while doing so!
