we recently purchased a used pontoon, it sat on the river for months without taking on any water.<br />then we got 10 inches of rain and it filled up and sank, obviously leaking into the pontoons from above.<br /> fiberglass pontoons with no foam .<br /> it is sitting in about 6 feet of water. <br />does any one have any ideas or links of how to get it back up?? <br />I would appreciate any help!<br /> marcia
