'Pitchpole'!
Hey Eric and Jerry,Wow! I assume spinnaker use on a 170 on SF Bay would be taken with a grain of salt. I've only pitchpoled my Laser before- planing downwind. But I bet those winds on SF Bay could easily make this occur to a larger boat like the 170. I'd imagine a spinnaker would only be safe on light to moderate SF Bay days. But I guess the point of a spinnaker on a dinghy is to power her up in light to moderate wind/ downwind legs? Not so much an attempt to break the sound barrier in heavier air?Best,Mike G.s/v Freebird
