Reguarding the Super Cat 19- I have a 84 model and the previous owner opted for the shroud lengthening option. It allows much easer righting by lengthening the top shroud quickly by pulling a pin. The shroud is easily shortened once righted- I hear not having capsized yet- anyone with experience- I wonder why more boats don't have this option?
I added one of these gizmos to my P19(#106) and it does work; makes righting a little easier, though I still can't right it solo. That was my aim, just did'nt work out that way.
