I was thinking that it would be better to put a
release buoy
& lifting eye on the rear of a
sub.
99% of the time you'd be driving forward into any
obstruction,
so if the gear was on the rear there would be less
chance of it being
obstructed also the lifting angle would be better
for pulling you out.

The advantage is that the arrangement is cheaper and less complex if
the reel carries the line. But looking at Phil's arrangement suggests that it
doesn't have to be. The wire strop through your reel axle seems pretty simple
and cheap, too. Moreover, it's already proven.
The real-reel issue for me is where to put something like this on Gamma
or a Kittredge. Almost anything I do puts the reel and buoys in the pilot's
way. Frank can bury one in his fairings, but the Nektons don't have any of
those. I'll have to cobble something together for a mock-up to see how best to
do it.

What's
the advantage of having the reel travel with the buoy instead of remaining
with the sub and unreeling from there?
Hi JT.
I don't see any advantage in having the reel attached to the buoy either.
It will just add weight and entanglement hazards to the buoy. Good idea on
marking the line to show depth.
Alan: My little sketch didn't show the release mechanism very well. My
thought was to use a spring loaded pin that keeps the latch on the buoy
closed. The "entrapped" pin in the thru-hull would push out the spring loaded
pin in the release mechanism, providing a positive lock on the buoy. The
thru-hull just needs to be a small one. I think a 3/8 inch nipple would be
fine with a 1/4 inch rod trapped inside with "O" rings to seal.
The valve would only be open for a few seconds to activate the
release.
Magnets might work but you still need a release mechanism of some
sort.
Lots of guys use a small hydraulic hand pump to activate the drop weight
latch. It would be fairly simple to add a valve and line to the pump to
activate the buoy release.
