Hard Dinghys out there?
You might want to consider a Trinka. These are beautiful little sailing dinghies that can handle a 2 hp outboard, be rowed, and (of course) sailed. I believe they come in 8 and 10 foot models. The 8 can be easily hoisted up on davits by one individual (I know, because I have a Trinka 8 hanging off my stern on davits). The drawbacks: they are expensive. May run you in the high $2k range for one. But then again, you get a sailing dinghy as well as a little motor launch. Also, they are not as stable as an inflatable, but then no hard dinghy is.
Just my 2 cents...
