Barca a vela : catamarano da crociera (su misura)
ATLANTIC 57
Alwoplast
- 17.37m 
57' 0"ft
She is not a completely a new design, but a refinement of the well proven Atlantic 55 Cat. Adding a little hull lengths is always a benefit to a catamaran and in case of the A57, the additional length also allowed a slight increase in the fore triangle area. Adding sail area to the staysail helps fill the gap in wind range between the small self tacking jib and the larger genoa.
Another interesting modification was the change to asymmetrical daggerboards. Prior A55’s had used either swing up centerboards or symmetrical daggers. Both worked well but it seemed that windward performance could be ratcheted up from excellent to spectacular by using a daggerboard that created extra lift. This is evident when sailing the A57 to windward as it makes no noticeable leeway.
