[PSUBS-MAILIST] sub test

[Alan via Personal_Submersibles]

Brian,
Could you get the sub to right if it turned upside down?
Personally I don't think it will, because you have got it to its most
precarious stage with just the conning tower out of the water. 
If it tipped to one side the conning tower would give it flotation & stop
it going right over. 
An experienced Triton pilot told me he gets under the water as fast as he
can, because that's when you are the most unstable.

>>                   Just got finished with yet another sub test down at the harbor.  Wow !  went extremely well !   This time I felt confident enough to put it in at the launch ramp,  sub very level upon floating it off the trailer.  I had this giant flotation buoy on the front since I wasn't quite sure what to expect !  ( I've been surprised before)  .  Everything seemed fine so I untied the big buoy and let the sub sit naturally.  It sat very level and nice!   Submerged nicely and by the time all the air was expelled I was down.   The first initial test was with the big buoy on the front , then untied the buoy and tried again .  I had a bit of a list going down that got me a bit spooked so I came back up.  But things are looking really good .  I probably could have transitioned through that list and gone down all the way but decided to come back up.  What I want to do is add a bit more ballast lead and then try again.  It's amazing what chopping off 6 feet off the front of your sub will do !!
