We made our boat trash can from high strength aluminum and then powder coat it in a rugged black finish. To keep the lid secured we used a rubber latch that will last for years. We then installed rubber bumpers on the bottom so this boat trash can wont slid or scratch the deck of your boat. You can use a standard 13-gallon tall kitchen trash bag as a liner or use the optional Fish Fighter Products boat bucket as a liner. Seems weird to put this much effort into a trash can for a boat but its the only way we know how to do things Build the best we can.
