First 21.7 S
Description
The boat has an optimized Length W.L.; it is hull-shape stable and an important ballast for its category provides it with the most low possible center of gravity. The stability and the Length W.L. result in good tacking characteristics (particularly in the breeze). The great Length W.L. provides a good reaching. The sails dimensions allow a good progress by light weather. The weak distortion of the bottom heeling and the two rudders give a good stability under sails as well as a good control of the boat.

Disclaimer. Boats are not all the same -- even when produced in the same factory of the same model. Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them. You should take the same precautions, especially when the data is not from Sailrite. The information on this site is not guaranteed to be accurate.
