hello! new here. a friend of mine just gave me and my boys a 15 1/2ft canoe to use on our 3 acre neighborhood pond. while im not entirely new to boating, we have never had a canoe before. this canoe will be used to troll around our pond for fishing... maybe a few "pleasure cruises" too from time to time.
i dont have a lot of $$ to spend on this canoe, ive already bought a 45 lb trolling motor and battery, oars, PFDs for all of us, etc.
i am building a set of outriggers for this canoe. im using very strong 1 1/2 inch aluminum angle stock for the supports which are 5 ft in length total. it is fastened to brackets bolted to the gunwales that I have made out of the same aluminum.
my plan is to use 2 6ft long 6 inch pvc pipes for the floats, with end caps that will be glued with pvc cement. i will use 1/2 threaded stock for the verticle supports that will be cut to length and will run from the angle aluminum, straight down through holes i will drill completely through the floats, and fastened with washers and locking nuts, and holes will be siliconed so that will be watertight.
i plan on filling the floats with some foam. this is my question:
marine grade foam is expensive. ive read on several forums about people using "Great Stuff" insulating foam that can be bought at home depot. From information i got off of dow chemicals website, i figure about 3-4 cans per float should fill them up completely. I will then cut the excess foam off, cap and glue the ends, and drill my holes for the supports.
i have read that even though this is a closed cell foam, this foam may deteriorate out in the elements, however, it will be in a water tight pvc float, far from out in the elements. will this foam work for what i need it to do? the pourable marine foam is just too expensive.
thanks in advance.
