I think your figures are fine. I was calculating based on five fired before the longer interval, and rounding the weight to 3,300 pounds.

Actually, if my math is right, and using 64.1 pounds for a cubic foot of sea water, bow tubes should hold 3,276 pounds (21.125" diameter, 252" length, according to the manual), so somehow it doesn't appear to be that big a difference in weight. Presumably the water from the WRT goes out the muzzle as well, so perhaps it's the difference between the combined weight of the torpedo and the water and the water alone.

I suppose the other possible question is, does the weight given for the torpedo include the warhead, or is that just the body? Add another 680 pounds and the difference becomes a little more significant.

I think it was in Submarine that Beach brought this up. It may not have been that big a weight difference, but firing several tubes in rapid succession it would presumably add up, and the weight is at the extreme forward end of the boat, resulting in a fair amount of leverage. At the moment, I can't find my copy so I can't look it up.
