[PSUBS-MAILIST] Test at boat yard

[hank pronk via Personal_Submersibles]

Brian,Can you not install a lighter tank, it sounds like it was not that bad if you could sink to hatch depth without the sub standing up.  I assume the tank is for buoyancy?  How big is it? how heavy is it?  When you sank to the hatch was all the air out of the MBT.  Maybe you just have a balance issue. Hank

 Hi All,              Did my test today down at the boat yard.  The good news is that is was really stable and no worries about it flipping over.  The bad new is that the nose is too heavy which I was fearing.   So once it was completely flooded the nose wanted to dive down.  But my motor pod behaved like it was suppose to , no leaks of wd40 or mineral oil from the vinyl tubing.    I think I had pretty close to the right amount of weight, took it down to the top of the conning tower.  So what I'm going to do is yank off that front tank which is too dam heavy and replace it with some foam or something.    I think I also confirmed that I can probably launch off the launch ramp next time instead of the big travel lift at the boat yard.  I will have some video coming soon !
