Building Rudder/Sealing Marine Plywood
Hi,I need some help as I have to build a rudder for my boat because my old one fell off some how towing it home. I wanted to just buy one but none of the salvage yards around here have one.
I was planning on using marine plywood and trying to design something similar to what I had before. It was a swing up rudder. My boat is 25 feet long and weighs about 4500 lbs. I figured I''d build something that goes about 3 1/2 - 4 feet deep and is about 18 inches long, and 3/4 inch wide. I''d round out the leading edge of the rudder and leave the back square. I''d have it swing down to the 3 1/2 or 4 level but when up only be about 12 inches. I''d probably just use ropes and blocks to lock it in postion.
Well there is my basic design idea, any feed back would be greatly apprieciated as I am not an extremely handy person. My question is what would you use to seal the marine plywood?
