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

Staring at Transoms

It is always better to be looking back at bows then staring at transoms!
We can help you with that.

It’s Original

One of the original colors of the Butterfly sailboat was this
buttercream yellow. It was a favorite of the Dallas fleet through
the years. I bet you did not know that this year marks the 60th
anniversary of the Butterfly sailboat class. Wow!

Butterfly sailboat solstice!

Today marks the first day of winter and the shortest
day of sunlight all year. So we felt a little Butterfly
sailboat sunshine would be a great call today. No
mellow yellow here just happy happy bright yellow
Butterfly sailboat glow.

Waiting for Santa

The beauty of the straight’s during the winter. Of
course we are waiting for a red sleigh to show up
and help this whole delivery process, but for now
we will enjoy the beauty of Butterfly sailboat country.
Thanks Michigan we know you love your
