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
