I recently had the same experience of attempting to right my H16 solo. I was not able to do it, and I had some wind. (I weigh in at 220) I am new to sailing and have a 1974 H16. My boat came with a long (8ft, 2in) fiberglass pole that was attached under the tramp. I had to replace the tramp this year and I took off the pole and did not put it back on. I believe this is a righting system (It is in the Hobie and Murray's catalog), but I do not know how it works. Can anyone tell me how this works?
Also, as I was trying to right my boat I was standing on the hull in the water and heard a crunch.

When I got the boat back to shore I inspected the hull and found the spot were I stood and crunched to be soft. The soft spot is just about in the middle of the tramp. I suspect this is not good. Is this a repair that needs to be fixed now, or can I wait?
The hull seems very thin on the sides. Is it repaired the same way a soft spot on the top of the hull would be fixed?
Thanks for the help.
