Trailer weight estimates; use this chart to approximate the weight of a typical boat trailer. these figures are based on a comparison of manufactured trailers and not. I have not seen any trailer manufacturers include the weight of their trailers on any brochures. how much does an aluminum i-beam tamdem axle boat. Looking for a comparison to try to figure out how much trailer weighs. it is a 2 axel aluminum trailer with disk brakes and bunks for a 21 w/a boat..
