I owned a pontoon for many years, and now own a 26 foot Chaparral Signature that I keep in Rocky Point. Not sure what kind of pontoon you're looking at, but on most pontoon boats with an outboard engine the bottom end/propeller is barely underwater. Even on a lake with one to two foot waves the prop on my pontoon boat would come out of the water whenever the front end dipped down in waves. I've boated the last few years around Rocky Point and the roughest area is approximately the first ten miles, as soon as you get about 10 miles out then it calms down. And I've noticed the first few miles around Rocky Point usually is pretty rough, and generally pontoons don't do well in rougher conditions. Rocky Point is generally pretty windy, and there's not too many days where it's real calm, optimum weather for a pontoon. I've seen pontoon boats in sheltered bays around southern Baja (Bahia Concepcion, Loreto), but I've never seen em in the open water around Rocky Point. So overall my opinion is a pontoon wouldn't do well around Rocky Point.
