There is a way to weigh the stuff on your boat using the boat.

Measure the distance from the boot top or deck to the waterline on each side
amidships. Take all the stuff off and measure again.

Then calculate the pounds that will sink the boat 1 inch thus:

Waterline length x beam (on waterline) x .7 x 5.33 pounds to change draft
one inch.

If your boat has fine ends reduce the .7 a bit or increase it for a full
ended boat.

You can also use this method to calculate how much to raise the boot top for
a certain load or increase in weight.

Hello Roger;

I'm impressed with your designs, nice web-site.

If it's not to much of a problem, could you tell me how much weight
would it take to increase draft 14" on a 12'X20' section of hull,
assuming it's a rectangle hull section.

Thanks

Just leave out the .7 which is a factor for the taper of the waterline. 14 x
12 x 20 x 5.33 = (where did I put my calculator?)

Salt water, right?

Thanks
Joe

Yes Sir, Salt water.
Or even better if you have the time.

I'm just curious how much cargo could be carried in a 12' X 20'
addition to my hull.

Making her hull 62ft overall.

My advice. Pay less attention to modifying your boat and pay more
attention to that babe standing there in the bikini. WOW! She's got some
bod on her.

Sorry, there is way more involved here than I can deal with through a
newsgroup. You need to hire a naval architect.

Yeah, If I did it, I'd do just that.

Using the simple formula you provided with the hull drawing 40"
leaving the freeboard she has (Keel not included) it comes to 51,168
lbs.

Figure the steel would weigh in around 10,000 pounds, toss in 2,000
lbs ballast, I would be able to carry around 40,000 pounds of cargo.
And again thats not counting the bouyancy provided by the full keel,
which should be able to float a big board and box.

Thats ball park enough for me. Not like I'm breaking out the plasma
cutter or anything.

Thanks

Joe
