First 18
Lifting keel

The First 18 is a sailboat compliant the Micro class rules. She was offered by Beneteau which designed her primarily as a coastal cruising boat. Freeboard is quite important; the waterline is wide to improve interior space. Also thanks to the very low placement of bunks the sensation of volume is increased.

Compared with other Micro, the First 18 is heavier and the wetted surface is larger. It is more difficult to keep speed with light winds but she is very fast as soon as the wind gets stronger taking advantage of her hull stability.
