Re: 1st Aid at Sea & Important Like Items to Carry
Look at it from a different perspective;
What could go wrong?
Stop the bleeding
Cauterize a wound
set a broken bone
Neutralize a nasty sting
Treat a serious burn
EPIRB & strobe
Treat a case of food poisoning
Harness, jack lines, and a fool proof assembly to recover a mob especially if it's you.
Redundancy in sails and rigging.
Keep a log
Learn skills to present a photo essay.
Weapons for personal security.
The above are the basics, imho.
