Good info to know. Thanks.
Normally, I would rest the boat's weight on the keel so the stands (or
drums) would be there more for balance than support. But my boat has
a stub keel that houses a centerboard and I'll need working room
underneath it to lower the centerboard at least partially. So that's
why the weight will all be on the stands/drums.
And thanks.....

On a humorous note, quick calculations reveal that if you fill each
drum with concrete and rebar, they should support in excess of
2,000,000 lbs each. :-)

I'll make note of that. It'll be useful for when I began work on my
houseboat conversion plan from a decommissioned aircraft carrier. :-)

If you fill them, I'd use something like sand or dirt.

I had 4 drums filled with wheel balancing weights. Each drum held
about 1800 lbs. The sat outside for several years and developed some
rust. I was able to pick them up without the bottoms falling out. Of
course that is the opposite direction of the force you're talking
about.
