This box absolutely fitted the bill for me when I was looking for a boat box that I could sit on. I knew that if I had a larger box then I would fill it ! It would then be too heavy to lug about and this box would force me in to rationalize the kit I took on board. One slight down point, the rubber seat pad quickly came off. I did a glueing repair job on it and it's now on for life. The description "strong" is certainly true, this box will stand a lot of abuse, a great box all round with it's separate layer lids. Just make sure your weighty items go in the main compartment and not the lids or it will topple over.
