Trimarans were chosen to be the best for all around sailing because they involve the least design compromises, when trying to achieve speed , safety and comfort. Using this design approach provides for very accurate determination of all engineering parameters, such as center of buoyancy, center of gravity and design displacement. Very accurate data for dimensioning drawings and final construction, is one of the other many benefits. All drawings have accurate scaled rulers, for dimensional takeoffs. Software is also supplied with which all drawings, tables of offsets and engineering design data can be viewed.
All designs are centerboard shoal drafted sloop and single-handed rigged.
Cruising comfort with adequate load carrying capacity for extended cruising are the main design criterion. The hulls sections are parabolic and the displacement curve follows a cosine function. The VPP was extremely difficult to write, but results have been substantiated with 381 model testing. If anything the VPP is conservative in it's predictions, which was the intended approach. Throughout the overall design approach has been conservative.
