Have you given any thought to the idea of a Nesting Dinghy
, stowed between the mast
& the companionway hatch
? I don't know how much room, exactly, there is on a Cal 39 for such (but am curious).
You might have a look at thehttp://http://ptwatercraft.com/ptwatercraft/PT11Home.html
PT 11. Russell's a good guy, and builds & designs quality stuff. And I've seen one of these firsthand, nice boat.
If you've got the deck
space in the locale where I mentioned, the "Spear" version might fit, which would likely be an even nicer option. Particularly as it'd be easier to fit a floatation collar to the whole boat in one piece, if one were inclined to add one.
How much room exactly do you have? Knowing that would make it a bit easier to assist with your conundrum. That & perhaps a picture of your cabin
Also, somewhere around here there's a thread where someone's inquiring after the pros & cons of stowing a dinghy on the foredeck, although, at the moment, I can find it.
