i'm making a small 12' trolling motor only, boat. the pontoons are foam filled. i had to add a 37"x 96"x 10" plastic coated foam block (about 1000lbs more bouyancy) in the back 2/3's to increase the flotation. now, with 4 batteries and me in the boat, i've got about 4" between the water level and the deck. the front remains at about the water level. the boat is obviously too heavy and needs more flotation, as well as less weight. my question is, if you look at the pictures, especially the front, is the upswept, pointed shape of the pontoons so limited in their carrying capacity that no matter how much weight i remove i'm still going to suffer from the same problem? i want to be able to fish 2 people. i have limited space on either side of the trailer runners to add more foam.
