As in many thinks in this life their exists the "Gray Zone" which consists of inspirational ideas that may prove out as beneficial, or impractical, or
. We're now about to enter the zone.
NEW SOUTH BAY PONTOON BOATS
â€¢3.5 PSI Air Pressurized & Chambered Pontoons
Air pressurized chambered tube construction, strengthens inner walls of pontoons. NO LEAKS!
Now as far as I'm aware of Forrest River is "maybe" the only manufacture that has an actual valve to maintain the recommended air pressure, but others may also exist.
I have 3 drain plugs on the top of each log. One for each chamber. The plugs have a small ( 1/16") hole in them to vent any pressure or vacume. I would assume it is a good idea for all pontoon logs to have a vent to prevent expansion or contraction from heat and cold.
I wouldn't advise trying to pressurize a pontoon log. It could end up costing you a bundle.
Why would having holes in your logs be a "good thing?" please splain this feature in some detail.
Lets see I have sealed logs yours as you stated have "holes" in them. We both stupidly hit something when traversing some shallow water and create some small perforations in our pontoons. We assume we're still ok and tie our boats off on the dock not to be seen again till the following weekend. We return the following weekend to view a horror. Your boat is practically sunk because your beneficial holes allowed all the air to escape and your toons are filled with "water". My boat suffering the same damage more or less is just listing a little in it's slip. The "sealed logs" pressurized the pontoons and prevented any or very little water to enter the pontoons themselves.
I'm thinking the "sealed logs" at least as the most practical pontoon.
