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

White Lake weekend!

Good luck to the White Lake Sailing School have a great weekend.

Does it float your boat!


This is a pretty cool take on the old milk jug flotation attempt. These air bladders are super light weight, and go up the back of the sail track with the sail. You keep them in place with the sail and the halyard. What’s the best part of them is the cost they are a fraction of the cost of the foam panels that we sell as well. Now you have choices you can make.

The Beauty of Butterfly Nationals!

The annual National Championship has something to offer one and all across all age groups. If you have come you know what we are talking about, if you have not participated you really are missing out. Next years event will be at Crystal Lake so start making plans for 2023. If you are a real planner pencil in Glen Lake in 2024. These are two of the best sites ever. Congrats to our winners and those that came and had a fun time.

Some MIchigan Love!


Are you ready for 2022 Butterfly Nationals! Let’s hit the water and go have some fun. We will have limited hours at the Boatworks as we support this years event.

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!
