I do see a fair amount of pontoon boats in the Barnegat bay. Many more than there was say 5-7 years ago. Even more so now, I see the Sundeck, fiberglass type boats with enclosed heads.
I live in a waterfront coummunity, and many of my neighbors use them to go up and down the canals. They also make for a nice day boat for crabbing and the like. However, I have been caught in many storms on the Barnegat Bay, and in some of those storms, a pontoon boat may not have held up so well. You REALLY need to watch the weather reports and the skies.....
