Rob,

On shore, you might still be able to right it with a pole...but remember that while in the water that you should orient the sails so that they point to the wind properly. The sail will provide a good deal of lift, aiding you in righting the boat, even with a gentle breeze. At 165lbs I could right my 5.2 single handed (using only a righting line) as long as it was blowing over 12knots.
