Being mostly in Gulf Coast waters, inland, I have a Stern's Type IV work vest that has two pockets.

In the pockets are a pr of leather gloves, a 55gal and a 35gal trashbags.

Attached to the upper mesh is an LED flashlight and a red tracking light.

Attached to the waist straps are two radio pouches. One pouch is reserved for a VHF-FM radio and the other pouch has a Doug Ritter PSK and a mini Sabre flashlight.

Also carried, attached to the waist strap is my plastic hardhat and an 8 inch Crescent Wrench.

I carry my EDC religiously and it is a heavier EDC when I am at work or in the woods.

There are certainly more items that could be carried but this seems to be the best all around equipment list for the areas that I play in. If my boat sinks slowly enough, I would have time to grab my E&E Kit which has rations and water purification as well as maps, fire making equipment, 550 paracord, and many other useful survival items.
