I have a new 18' Seaark 72" bottom mod v tunnel hull that is 1/8" thickness. I want to toughen up the bottom of hull. I plan to add another 1/8" 5086 aluminum sheet to bottom and then plug weld 1/2" uhmw to that before I attach the motor. Feasible ? I know its alot of work, but have my own aluminum mig welder and work for free. Why not start with a 1/4 " hull boat? Long story, but this is what I got to work with. My calculations are tha that I would add 250 lbs of material. The motor is a 115/80 4 stroke jet. The attached picture is of hull just like mine. It has 7 strakes front to rear! My questions are, would it be better to add flat aluminum sheet between strakes, then add aluminum angle bar over existing strakes? Or try to match complete bottom with full sheets with use of metal bending brake? Recommend use of 3m 5200 sealer between hull and additional aluminum? How to attach uhmw over 7 vee shaped strakes? Leave uhwm off of strakes and install uhmw between strakes? I would be grateful for any or all answers. 1/8" hulls will not handle "rock rash" of Alaskan rivers.
