I've been following this discussion for some time now, and I'm starting to think that maybe I'm doing something wrong.
I routinely fly my symetrical
spinnaker alone on my 36' catamaran, and have never had any problems. I don't use a pole, And the sail seems to self adjust in slight wind shifts. The
autopilot handles everything quite easily. I've used it in 18 knots true, for several hours heading down Delaware Bay last summer, and it was just pleasant cruising.
But after reading all of the posts, I'm wondering if my
spinnaker is under-sized for my boat. Maybe that's why I'm not experiencing the same problems. I also don't have exceptional speed when flying it. I don't use the main when the
spinnaker is up and I'm alone.
How can I tell if the sail is undersized?
