Hey guys. I did the first dive in trustworthy. The boat is bone dry with no
leaks or even weeping after being in the water for three hours. I did have a
few electrical problems due to not getting the grounding bolt area clean
enough of epoxy paint, but that is a easy fix. A problem I had was not
weighing enough. It was me and a buddy we both weigh 175 pounds or so. The
two drop weights are 250 pounds total (same as kitteredge). I ended up
putting 100 pounds of lifting weights, about 200 pounds of old jacks and it
still wouldn't go down. I had the safty dives stand on it and it went down.
After scrathing my head for a while I decided the scuba tanks on the outside
which had 100 pounds negative boancy now is close to 0 boyancy so that makes
due for a little, of the extra floatation. But what about the extra weight
of the jacks and the divers? The only thing I can think of is the tanks were
not venting well. I notice they got hydro locked way to easy. It seems like
the 1/2 " line is way to small. So the only thing I can figure out is maybe
the ballest tanks were not venting all the way. Everything about my sub is
built just like the blue prints so that is the only thing I can think of
about it being to bouant. Any thoughts?

Thanks,

Scott Waters
