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.

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
