Additional realizations/comments:

General Note:
The only event that would cause me to leave this boat & still have time to gather equipment/supplies first: IS an EMP event!

No, I would not try to carry or make use of all of my bags and other gear. I would share my excess bags with my shipmates that need some bags to carry their BoB type gear.

The life jacket gets stripped and dropped as soon as I get onshore!

From the boat: Fire axe

Equipment/Supplies Notes:
The PVC tube can carry additional water from the boat.

From 1 messenger bag: Large plastic coffee cup w/lid.
