Jamie,

I'm 65Kg and have only once failed to pull the Stealth back on my own (admittedly it has a carbon mast). This one occasion I'd capsized about 4 times in one race , and on the fifth the boat just wouldn't come back - a combination of tiredness and the subsequent discovery of about a couple of litres of water in the mast!

Whatever else you do (waterbag etc.) MAKE SURE your mast is watertight. I've since done so by pressurising the mast with a small paint spray compressor and testing the length of the mast for leaks. I found two major ones at the hounds and one of the upper diamond tangs - I filled them with epoxy mixed with microballoons, problem solved!
