I am planning on installing a raised floor on my boat which will be placed over two bench seats. One of the bench seats currently has a cooler builtt ito the middle of the seat. I would like to place a seat and seat post above the cooler by installing the seat on the deck hatch so i can still access the cooler. Do you know if this hatch will support a seat and someone sitting on the seat.
Response - these hatches are designed to take the load of someone sitting on them or standing on them. They will not take the localized load of a seat post being bolted through them and then a seat above that. The hinges and lid is not that rugged.
However, there are aluminum hatches that could take such a load. What you were looking at was a 13x17, here is 12x18
