[PSUBS-MAILIST] Drop weight design

[James Frankland via Personal_Submersibles]

Brian,

On my sub, I am constantly moving weights around internally to balance the
boat and help vent the main tanks.  If I could move the dropweights with a
handle, like a plane trim control it would be easier.  I am going to make
this a feature of my new boat.  Just a thought..
regards
James
