KL, you have described a Rigid Inflatable boat to a tee!
You might have to carry a tent and a sleeping bag occasionally, but for
your other requirements, nothing in the big heavy world of fiberglass would
bring you near as much satisfaction, without a lot of misery and expense...good
luck shopping.

I don't know why you don't want an outboard.

A blow up is fine, or a flat bottom skiff ( semi Vee ) with a square
nose may be usefull. Put a ladder on the front and enter/exit from
there instead of by the out drive.

Go look at boat stores and storage areas in your FLA area. You'll
probably get more ideas there.
