WINDWARD BOATWORKS

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

We celebrate 30 years of scows and boat building!

In our wildest dreams we never really thought that we would build all the projects that we have. It has been quite the adventure to say the least. It has ranged from three different scow classes to the Butterfly and in between. We have built training boats, life boats and many wild things as well. Here is to the next adventure.

Starts Today

Don’t wait to get your custom colored deck Butterfly sailboat ordered. Our Butterfly sailboat Fall discount begins today, don’t miss out on the best pricing of the entire year.

Fall Discount

It is the time of year when we offer our fall discount on new Butterflies. This sale period starts on August 25th and runs through the first week of September. It is your best pricing on a new Butterfly for the entire year. As you may or may not have heard we will only be building colored decks through the end of October as we then shift to strictly white hull and deck Butterflies for the remainder of the building season. So if you are interested in that custom color now is the time to order.

Be an original!

Can you believe that the first Inland 20 Nationals was 27 years ago up on Castle Rock Lake. Boy were we all a lot younger. Good times they were.

Keep on sailing!

The season is just rushing along so keep your Butterfly sailboats on the water having fun everybody.

2025 Butterfly Nationals at White Lake

What a great event at White Lake for the Nationals this year. We had one of the biggest turnouts in some time with 27 junior teams racing and 42 Butterfly sailboats in the open fleet. This is one of the largest and most competitive open fleets in some time. The White L:ake YC did a great job and many thanks to Chris and Liz Oertel, Ande Holly, the White Lake YC and all those involved. WE had sailors from all over the country and every fleet is seeing growth in their programs. Keep up the good work.

Butterfly sailboats in frost green!

Every once in a while a certain color comes along that is really cool. This Butterfly sailboat color is really bright and also looks great on the water.
