Starboard

How strong is Starboard??

I have to fish boxes in the floor of my boat that have the oringal Teak wood covers. One borke last year and I repaired for now.
But I was thinking of just making some out of Starboard??
They are about 3 feet long and about 20 inches wide?? This is a guess as the boat is still covered up. They have at least a 1/2" lip all the way around the edge and they need to be walked on all the time!
Do you think it is strong anough to take what I can dish out which will be alot!
