My tally for 2009 (all the same sub):

Gasket leaked - 1 recovery (sunk, knee-high water at edge of pond, February - cold)

Rudder needing adjustment plus moderate convection current - 1 recovery (sub floating, waded chest-high to middle of vast retention pond)

Deep-sea weed - 1 recovery (sub caught 4 feet down, rudder wrapped, in well-kept little pond with fountain)

Bright, flashing deck lights sure are helpful to mark a disabled sub after dark.

Cold cold water, St. Lawerence River, last week. Went down too deep dynamic dive, hit negitive box compression and the bottom, about 12 - 15 feet down. There it sat stuck in the weeds, wrapped around the tail. I sat on the river side and said a prayer....along comes a guy, singing to his ipod, having a great day in his beautiful gold sea kyack. It was like an angel from heaven. I called him over and told him my tale of woe. He went down stream and I met him there with a stick I had found on shore that was just about right for someone in a boat. In fact it was just right, the guy got the sub with the fork of the stick, under the sail planes, and around 6ft the sub became positive boyance and came up the rest of the way on its own. Man was I happy. My first sub, my first loss and recovery.
Whew! I realize that one must stay very close to shore as the water here is way too cold to go into, about 5c !

Anyway remember negitive box compression is reached at an earlier depth due cold water and that with dynamic divers, a APC is a must.

That compression sounds like a subtle trap (I've always built with pvc and the walls don't flex, though compression can still happen : if my cylinder leaks at a shallow depth, it should admit more water in a deeper dive as the inside air compresses). Not to mention...weeds, the nemesis of the r/c submariner !
