Re: [PSUBS-MAILIST] Safety Hook

Dont forget to take in consideration the bow effect(in deeper water)  that any current will have on the rescue cable . The hook will have to be very  heavy otherwise it will be useless in stronger current.

Hi Frank, Looks good.
You could spring load your device by putting a rubber O ring in a grove round
the outside of the prongs, if it were necessary.
The lifting eye would be vertical when the emergency line was tightened
providing the line from the drum was above the lifting eye.
I googled round a bit trying to find something "off the shelf" that would work but no
success so far. It's a big world, there's bound to be something out there.

Here's a little sketch on an idea I had for a simple hook to follow the buoy line down. It's much like Phil's idea, but I'm using the lifting eyes I have welded to my sub. With a "three prong" approach, ONE of those damn things ought to grab.
It would operate like a fish hook where the support crew would keep "jigging" the hook up and down until it grabbed.
Any comments ?
