Oh yea,
The box I desribed above is not that heavy, the T-111 siding is aobut 3/8 inch, with some gooves in it.
I've built the frame such as to allow me, or a number of people to stand anywhere on the top without a problem. It's great for standing on it when rigging, stepping/ de-stepping the mast, etc. At races, or pleasure sailing, many people can sit, lay, etc. It's a 8' x 12' table top when closed.
