Windward Boatworks is your complete source for Butterfly Sailboats & Parts. We have been building Butterfly sailboats since 2006.  Butterfly sailboats are large enough to accommodate several people, fast enough for serious competition, light enough for launching by one person, and virtually maintenance free. The Butterfly has a strong National Organization and holds annual National Championship regattas. From a cottage boat to serious one-design racer – the Butterfly does it all.

What’s New with Windward Boatworks and Butterfly Sailboats

Crystal Lake lineup!

The start of summer fun up at Crystal Lake YC as the Butterfly fleet starts to populate the club. How many Butterfly Sailboats will line the beach front this year? A bet there will be many!

Suns up fun’s up

The past few weeks we have had typical spring weather, rain mixed with snow and overcast it seems all the time. So to brighten us all up we built a sunshine yellow Butterfly sailboat. Everybody needs a fun Butterfly sailboat!
