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

Rainbow in the bag

Everyone loves the original Rainbow Butterfly sail.
So if you want the latest in old style cool for your
Butterfly Sailboat you need to get the updated and
improved Butterfly sail. Our sails come numbered
and with window at no additional cost. That is a
big savings over the rest.

The Butterfly sail colors of the Holidays

The colors are in stock for your Butterfly sail so many
colors to chose from. If you want to make your Butterfly
sailboat really fly, a Butterfly sail is the best gift ever.
Surprise your sailor for next season.

The Perfect Gift!

How about a new Butterfly sailboat for the sailor in
the family or maybe the whole family. Maybe a new
Butterfly sail for the ultimate gift this year. Whatever
the choice we are here for you.

Have a great Holiday Season!

Open the Hatch!

Did you know that Butterfly sailboats in the early days
had a glove box. Some call it a storage cubby others
call it the hatch. We have come across a bunch of these
they are used but still good. We are also working on a
new version right now. Does your Butterfly sailboat have

Wrap it up

Are you sick of your Butterfly sail and boom banging up
your car. Is it a mess to transport back and forth? Well
here is the answer for your Butterfly sailor. A full cover
that goes over the Butterfly sail and boom. Its vented
for airflow and keeps everything safe. Harken quality
made exclusively for Windward Boatworks.

More Butterfly Regatta Room!

If you have just too many Butterfly sailboat parts in
your vehicle and you need space. We are building
and adding these to our trailers and also our trucks.
They work great for iceboats and other sailboats
as well. They have shocks and locks! Butterfly ready!

Pick a color any color!

So when you order a new Butterfly sailboat or Barnett 1400 you get choices. Of course you can pick the deck color, maybe a deck stripe or simply
a cool graphic but the cool part is picking your own sail. Our sail makers
use the best material on the market. It lasts longer, keeps it color and
holds it shape due to the high quality of the inputs. So pick the cool colors
for your Butterfly sailboat and get noticed!

World’s best cover

So now seems like an odd time to talk covers, but the Harken cover has only gotten better. They made a couple of more refinements and guess what it is the best on the market…again. We love their hardware
and we love their cover too. Get your Butterfly cover for next season, it

makes a great holiday gift.

Fall colors and new Butterfly Sailboats!

What a beautiful day in Northern Michigan to be bringing over 2021 Butterfly sailboats and
all the gear. Get your club ready for the start
of next years season a little early. Get ahead
of the others as well. See you on the starting
line in White Lake!

The Big Dip

Did you know that for your Butterfly daggerboard
and also your Butterfly tiller and grab rails, we dip
coat them. The beauty of dipping or as we say the
big dip is that the finish looks great and lasts longer.
So for your Butterfly Sailboat get the dipped parts.
