Tortoise sail on my Roar

See:

for photos of my experiment
mounting the sail from my Tortoise
and the dagger board on my
Mickalak Roar.

It handled well, and I had
lot of fun. I used an oar in
the 'sculling knotch' for a
rudder, and it worked great,
perhaps even better than a
regular rudder because of the
increased lever arm.
