I've used a 10' portabote for the past four sailing seasons (Great Lakes sailor). It's been very good for our purposes.
lightweight, strong and durable, good to row, large volume, can easily be stored out of the water on our deck, can be sailed (as a toy).
assembly/disassembly takes 15 minutes and some effort, storage on deck blocks some ports, seems tippy until you get used to it, can only accommodate a small outboard (not really a con for me, but some might think so).
The biggest issues for me are storage on deck, and rowability. I dislike dragging a dingy any distance, and I also hate having to use an outboard to go a short distance.
, you ask about the sailing characteristics. Not great is what I would say. It's a fun toy to play around with in an anchorage, but it's a pretty poor sailboat with its clunky and light lateen rig, and the need for side dagger boards. That said, it really is a lot of fun to play with. Sure beats motoring around
