Re: beach friendly boat advice
Yes the P16 is a more robust construction but it weighs more, harder to handle on the beach but the cross-beam hull connection is way stronger. That was a major failure point in the h17. The H17 is easy to handle on beach wheels, 400 and something lbs.
To the original poster, I located you in Ca and being inland, fresh water, lakes - (what is that huge one NE of SAC?) I would definitely urge you to look at the H17. The wings are the sh*t, very comfy and useful upwind, but watch out for broken wing sockets, e.i. inspect each of them, and the cross beam connection as prev.mentioned. Problem is, it is hard to see, look from underneath to spot corrosion.
I may have miss-posted about motoring and access. Usually w/smaller boats motors are not an option anyway. i am sure you know, Paddles are very effective w/smaller boats. Wind and current conditions are a factor as always. If you have perfect beach access, then you are set.
