Design Concept
The goal of the Storm Trysail Club and Transpacific Yacht Club was to create a boat that could compete as a Box Rule and as an IRC or ORR performer. The benefit of a Box Rule – one that limits factors such as length, minimum displacement, draft, sail area etc. – is that it maximizes performance. The STP 65 rule promotes a high-performance boat for both inshore and offshore sailing, with tight enough parameters to minimize obsolescence. The “box” sets an LOA of 20 meters (65.6ft), displacement range of 13,000Kg to 13,400 Kg, beam range 4.5m to 4.8m, a lifting keel that allows a generous racing draft of 4.8m (15’ 9”); and a healthy sail plan. The lifting keel will reduce draft to 3.3 m (10’ 10”). Displacement/length and sail area/displacement ratios are between the TP 52’s and Volvo 70’s giving promise that the boat will deliver lively performance in long distance and buoy events.

Farr Yacht Design developed the first design of the new Storm Trysail-Transpac 65 for Rosebud owner, Roger Sturgeon. The Storm Trysail-Transpac 65 (STP 65) is a high performance, light displacement, fixed keel box-rule class announced in August 2005.

In the months that followed, Farr Yacht Design worked closely with Bill Lee and others to assemble this new Box Rule. Roger Sturgeon and his project manager, Malcolm Park, were also an integral part of the rule creation and commissioned Farr Yacht Design to design their first boat of this class. Westerly Marine of Santa Ana, California, was commissioned to build Rosebud.

Construction
Rosebud, an all carbon fibre pre-preg construction, was built to strict STP-65 box rule specs. ATL Composites manufactured custom DuFLEX interior furniture components and floors that were constructed with aramid honeycomb and AIREX structural cores, laminated with carbon fibre skins. All components were QA’d to meet tight tolerances in weight and strength for the box rule spec.
