First off, I'm really not trying to flame you here, but why are you so hung up on it being an auto? Don't get me wrong, autos are cool and fun to play with, but about as practical as a Ferrari as your daily driver. Good ones, not great ones mind you, run as much as the higher end benchmade folders. Even then they are less durable than a good folder. They aren't even really that fast. I can snap my Axis locks open faster than I can find the release button on either my Benchmade automatic or my udt. If you want a practical tool to use around the water I wouldn't go with the automatic. In fact, if you are going to be in and out of the water a bit I wouldn't even suggest a high end folder. I'm amazed how many things have been lost by being dropped into relatively shallow water. I'd hate to lose a $200 knife that way. For your stated needs I'd suggest a BM griptillion or even (I can't believe I'm saying this) a cold steel voyager. Both are sturdy, sharp, can be opened quickly with one hand, and are cheap enough that I wouldn't feel bad about losing them or breaking the blade by using it instead of a screwdriver to pry things. But thats just my opinion. My go to utility blade is a BM TSEK.
