Re: 1st Aid at Sea & Important Like Items to Carry
Highfly, there are plenty of threads on this, here and elsewhere.
A "first aid kit" basically is what you use for headaches and splinters and booboos, and yes a $10-15 kit from a bigbox store is just fine.
What you might want on the boat is a "trauma kit" or "first responders kit" or "medic kit" which is where you get into a fast $200-500 if you buy it prefilled. That's going to have the splints, bandage rolls, heavy meds, etc. that may be needed offshore. You can get the meds by asking your doctor for rxes after explaining the purpose to him. If he's a schmuck and doesn't want to help, you go elsewhere, and if you are the captain of a federally documented vessel you can order drugs directly from a "dispensary pharmacy" which is allowed to sell them to you directly that way, no doctor required. Your local pharmacy should be able to assist in that--assuming they aren't a clueless bigbox shop.
