RE: Uphauling a 10 m sail on shortboard (iSonic 133)
I agree that you should be easily able to uphaul the 10.0 on the 133.
One thing I have found that helps immensely is the addition of an "easy uphaul" type device on your uphaul line. It is easily made with a length of downhaul line and a small piece of harness line plastic tubing. Very inexpensive and simple to install, but it helps you with dumping the water off the sail to clear the mast and get it up out of the water.
After you dump the water off, and the sail gets close to vertical, the rest is the (phyically)easy part. I can't believe I went so long without using the easy uphaul device...try it, you'll like it.
