Houseboat floatation
My uncle's houseboat floats on 2 foam filled doughnuts that are encased in fiberglass. The doughnuts measure 10 ft and they're fastened together with stainless steel brackets and bolts. The entire houseboat is 20 ft X 30 ft with the 2 doughnuts being in the center. We put 33 drums around the doughnuts for stability and to support the porches on both ends. Houseboat has been docked since end of 05 and the only thing we had to do so far was swap out a few barrels every other year or so. The barrels are not foam filled just seal the bung and the air will stay in there a long time. When you see the houseboat listing to one side pull out some old barrels and put in new ones. You can usually reuse the old barrels b/c they usually just leak around the bung threads. Hope I helped...
