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
Joe

How much does the sailing equipment, the "Stuff" weigh? Any idea

Around 3000 pounds including food stock on a 42fter.

You are underestimating probably by a factor of at least two. Let's
be
realistic about it Your anchors, chain and windlass alone probably
weight around half a ton. The fuel and water and holding tank close
to
500 pounds. That's half your 3000 pounds already.

Put it this way. A Coronado 27 has an empty weight of about 5700
pounds.
It says on Capt. Neal's website somewhere, if I recall correctly,
that
the last time the Good Captain has his blue water yacht in a travel
lift
for a haulout it tipped the scales at 8,800 pounds. And it's only a
27-footer. Yours, being a 42-footer, it's more likely you're hauling
around probably at least three or four extra tons of stuff.

Well if you include water and fuel then another 7012.5 lbs.

Opps my mistake, it's only 4000 more pounds. 500 gallons (350 fuel 150
water)..@ approx 8 lbs per gallon.

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?

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.

From this: http://sports.webshots.com/photo/124...63212926VskyTX

To this : http://good-times.webshots.com/photo...63212926pEcMjp

Adding two of these: http://good-times.webshots.com/photo...63212926AEPHFI

Making her hull 62ft overall.

Thanks

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

When I really got serious about racing my old Cal-34 we'd go through
this excercise of taking all the cruising gear off of the boat. It
was usually about 2 full size station wagon loads, and probably
weighed 400 to 500 pounds. That is enough to make a very noticable
difference in light wind performance.

That's why we don't race in light wind ;-)

Joe's got the right idea. His boat is made from steel. Steel does not
absorb water.

I can tell you from experience that steel boats
get blisters too ;-)
