Composite decking for a jonboat floor

That composite decking is very heavy. I would use exterior plywood treated with thompsons water seal before i went composite decking, as a sheet of thin plywood doesn't weigh that much. The last composite decking i stood on was very slippery when wet also. Add in some slime, or bait on the floor and you have the great potential for accidents or overboards. Aluminum isn't that expensive when you figure that it will last as long as the boat.
