[TheForge] Way off topic: boat dock

[Bob Ehrenberger]

Grant,

Thanks for the information.  I have been putting of building the dock for 
some 8 years. Just never seems to be any free time.  Then a couple months 
ago I was looking ar my resource pile and noticed a large frame that was 
originally industrial shelfing. It's 4' wide and about 15' long. The idea 
came to me that all I had to do was get enough flotation uder it and build a 
deck and I was done.  In the time I have been thinking about this frame it 
came to me that I can simplify it even more by using wooden pallets for the 
decking.  I can lift one end by myself so I think it is probably under 400 
pounds. For stability I was thinking of putting two barrels under each end. 
The barrels will stick out past the edge of the dock and give it a bigger 
foot print.

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?
