I'd bet that the Ranger 23' could handle the winds on SF Bay if you can. The Ranger 23' might be easier to single hand then a Sonar (also 23') or similar fast dinghy like sail boat.
People have found ways of sinking J 24's in NY Harbor: The Sinking of 12
The formula for sinking a J 24 seems to be simple: do not close companionway and do not latch lazarettes in cockpit closed, then get knocked down.
I doubt that a Ranger 23' would plane like a J 24 (or at all) but for single handing I'd rather have some serious weight below like the R 23 has. We race against one in PHRF beer can races and the R 23 can be a spoiler for my Tartan 27'. We race in the 'high' PHRF division (>186).
Are there any Tanzer 22's in the SF Bay area?
