![]() Weight is not as much of a concern on a grain trailer as it is on a boat. I am familiar with the different needs involved between a boat hull and a grain trailer. I have a retired friend who had a large trailer manufacturing business. I am pretty sure grain trailers use aluminum types containing different alloys, and of a different hardness than the types of aluminum used in a boat hulls. Marine aluminum consists of specific types of aluminum, which have the qualities necessary for the needs of a marine application. Riveting is not really feasible for thick, heavy types of aluminum. Riveting is labor intensive and much more expensive than welding. the short story on riveting and welding amounts to the needs of the application of the product involved. I have a lot of experience relating to this question so I answered specific to what he asked. You should start your own thread with that question. Maybe a better question is if the boat leaks is a rivet or a weld easier to fix. And if one was far Superior then the other, well id say that every manufacturer of aluminium boats would be doing it that way. I say it depends on which brand of boat you like will influence the rivet vs weld debate. Go look at a set of aluminium grain trailers,not one rivet. If you treat it badly, it may fail within 5 years. If you treat the hull with consideration, you will easily get 20-50 years out of an aluminum hull. I have also seen some 2015 aluminum hulled boats which have been subjected to some terrible conditions in some really severe wind and wave conditions and have hulls that have failed completely However, over the years, I have been at some Canadian resorts who have aluminum riveted hull camp boats that were purchased in the 50s and are still running strong with no leaks. So, it is usage style that determines the life of a hull. if the boat is sitting on an indoor swimming pool, the aluminum hull will likely last 500 years.īut, if the boat is subjected to a constant 4 foot wave while running at maximum speed rated for the boat, you may very well cause the hull to fail within a year. Rather the real number to be concerned with on a riveted aluminum boat is the number of waves that the hull crashes over per year. Apply a bead of Aluminum Boat Leak Sealer around the rivet head to form a flexible, waterproof seal.The number of hours you put on a boat is really not that important. Attach a static mixing tip to the Aluminum Boat Leak Sealer cartridge and insert the cartridge into a caulk gun. TotalBoat Aluminum Boat Leak Sealer: Use 80-grit sandpaper to sand within a 1" radius of the rivet head until the metal is bright and shiny. Use the filled syringe to apply the epoxy around the head of the rivet.Īfter filling the rivet, heat it with a heat gun to help the epoxy penetrate completely and set quickly. Heat the rivet with a heat gun or propane torch to remove any remaining water. Mix the resin and hardener components, as directed, and transfer it to a plastic epoxy syringe. West System G/Flex 650-Kįor either of these epoxy products, you can use a wire brush to expose bright metal around the rivet. ![]() When the boat is dry and clean, repair leaking rivets with an epoxy-based sealer such as West System G/Flex 650-K Aluminum Boat Repair Kit, TotalBoat Fle圎pox, or TotalBoat Aluminum Boat Leak Sealer, according to the manufacturer's directions. If the rivet holds the vacuum seal, it's good if it doesn't hold the seal, it will leak. Place it over a rivet, and pull a vacuum with it. If you don't want to fill the boat with water or it's the middle of winter and you can't fill the boat with water, an alternative is to use a small suction cup-type dent puller. The first way is to fill the boat with water (easier to do while it's on the trailer), or fill it part way with water, and use a marker to circle any rivets that leak. ![]() There are a couple of ways to find leaking rivets. Rivets leak because wear and tear eventually loosens them, causing gaps where water can get through.
