It's a real shame about that boat accident, but I'm glad to hear you all made it out ok. Just a thought though, did anyone try contacting the insurance company? It might be worth pursuing to get them to pay for a salvage attempt?
I can definitely relate though, it's a damn shame for your loss.
Several of us have lost firearms in that same area. The hidden rocks in that area are very bad, and the sea water does damage to firearms in very short order. The currents are so swift that recovery would be extremely dangerous. Several people have asked for the exact location, but we are concerned that they would be injured while attempting to recover a firearm that is already damaged beyond repair.
