The weight of freshwater you displace is 62.4 lbs x your total volume in
cuft. The weight of seawater you displace is 64.0 lbs x your total volume in
cuft. So the extra lead you'll need to counter the additional buoyancy of
the seawater is given by:
W = (64.0 - 62.4) x V Where W is in lbs and V is your total volume
in cuft.
To find the total volume of yourself and your gear fill a really big tub
with water, totally submerge in it and measure how far the water line rises.
Multiply that by the surface area of the water surface to get your total
volume (V) :-)
Or just take a guess and get in the ocean and do a buoyancy test.
