Can I increase performance of the Tiki 38 by increasing beam and sail area?
If you increase the beam of a TIKI 38 by 2 feet and its sail area by 25%, you will have changed the ‘nature’ of the design. The TIKI 38 in its vital statistics figures can be classed as a ‘Performance Catamaran’. Increase its beam and sail area 20-25% and it then has the statistics of a ‘Racing Catamaran’. They carry higher stresses and capsize in force 5 wind gusts. Increasing the beam by 2 feet also requires a number of design changes to compensate for seriously increased stresses.
