Hmm... sounds like you might be better off with a 16..

You can push it off the beach and most importantly drag it up the beach without an army... The Pcat will just be heavy to deal with on the sand. You could put it on a moring for the day, night, or weekend if that would work for you... still a beach needs a beach boat.

What you really need is a former Pcat sailor to explain how manageable the boat is. 650lbs.. sounds like H21 terrority and this boat is not built like a H21.

Different circumstance that particular Pcat might be a perfect boat but it sounds like you want another beach toy and that is what the 16 was created for...
