Ok...so Sunday was the "Maiden Voyage" of my recently purchased 1979 Poontoon. Wish I could say it went well but I almost sank the dang thing! We had 9 people on board and we skirting the waters edge the whole time. At one point, we throttled down w/ too many people up front and about went "Red October!" My question for you guys is floatation...What are some ways I can keep this thing afloat? A thrid pontoon? "Foaming" the two pontoons there already?? I'm interested to hear what you guys have to say...thanks in advance for the help!
