[PSUBS-MAILIST] sub test

Looks great, Brian.

Good photos. A list is not necessarily instability. Perhaps it a trim issue?  A little less stability can be expected during submerging and surfacing transition.

Hi All,

                  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 !!    

 

Sorry no video but I do have a few stills that I will try to get up.  But all in all things are finally looking really good.  

 

 

Brian
