I agree, way too much good stuff for me. With the sailing I intend to do, I should be rescued within 5 days, if weather is bad, 10 days.
My ditch bag is small.
Manual water maker and plastic cup
Waterproof energy bars x 5
Mirror and dye
Fishing hooks and line, just give me something to do
Portable VHS, Eneloop batteries, solar charger (optional)
Emergency blanket and washcloth
With my fanny pack on me all the time, I will have sunglasses, WP iPhone, multi-tool, and other goodies.
I always prepare my ditch bag. Just like bringing an umbrella, it you have it, it will never rain. It works every time; my grand Mom said so.
