Re: [PSUBS-MAILIST] Underwater Anchor System
Hi;
I understand the dangers of the idea but it is based in situations in which
you have to stay in a position for example, near an underwater rocks where
currents are strong, for some time without draining you batteries. The ideas
so far given are with a type of anchor that has a line quite long enough to
surface with the anchor still deployed in which thw winch is really doing
the work of holdin the sub on the desired position. Also and idea was
suggested to have a mechanism to cut the line remotely to prevent the sub to
being an underwater coffin.
I wonder if a yacht type submarine might have one as it wouldn't be a nice
surprise to realize after some time preparing a sandwich in the galley that
you are adrift a couple of nautical miles.
Also, I think that in this hypothetical situatuion the thrusters will
require a good autopilot and gps to maintain a depth and position.
