This 5 meter spritsail rig makes a canoe go really fast. It’s easy to build, easy to control, easy to put up and take down. It tolerated gusts well and can be tuned for really light winds also. I use an aluminum sign as a leeboard and steer with a paddle.

I did a similar thing when I was a kid, but we tied 4 canoes together and strung a tarp between two paddles. It’s hard to know how far we sailed like this from lake to lake (northern MN), but it had to be 15-20 miles. Great fun.
Not exactly a “weather helm” though
