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.

Minnesota Iceboating

The iceboating season keeps plugging along even in Minnesota. A brand new Skimmer 45 being sailed up in the Twin Cities. Thanks P Heppart for picture.

Dig that ice color!

Thank you Don S for the great photo! I hope you had a great day of kicksledding out on the ice of Madison, Wisconsin. Nothing beats a Kickspark Max.

Time to iceboat!

We were out testing some new equipment Skimmer 45 iceboats and stuff, and also looking at some used sails as well. It is always fun to grab Sam and go down to Madison and the Capital to enjoy Lake Mendota.

On to 2024!

The last weeks of 2023 were a blur as we prepped Butterfly’s going out, Skimmers being built and boxed, Inland 20’s in final production, and a host of other projects. It was a great 23′ and 2024 looks to be twice as busy.

We are ready!


Are you looking for that really cool lake play toy that the entire family can use? Well soon enough we will have ice on the lakes and you will want one of these.

Traditional kicksled


What a great way to spend the holidays and also this winter, on a kicksled. We have these in stock in a variety of sizes. Get one for you, your family or maybe for up at the cottage. They are a blast.

Let’s go kicking sledding!
