[TheForge] Way off topic: boat dock

[Grant Marcoux]

Bob:  You can also get a very accurate idea by measuring the volume of water
displaced.  Detrmine cubic feet and multiply by 64.4 for fresh water.  In
underwater lift problems, we calculated the volume of water we needed to
displace when we chose our lift bags.

You are right at 440 lbs, stability is another issue.

I'm planning on building a boat dock this summer and was wondering if any of
you knew how much flotation you get from a 55 gal drum?  I have several
available but don't want to over kill it too bad if I can help it. The way I
figure it 55 gal of water would weigh 440 lbs so each drum should hold up
400 pounds. Does this sound right to you?
