It should also contain items more likely applicable to boating as opposed to a general home first aid kit.
Water should also be carried.
It doesn’t matter if you are out for just a few hours or an extended trip, it would always be preferable to have someone on board with up-to-date first aid qualifications. If a person is in serious jeopardy, try a pan pan call on VHF 16. There may be a doctor or someone with first aid qualifications nearby. Remember, if you are out for an extended passage, make sure you take some spares for the first aid kit.
Some Boat Safe retailers sell boating specific first aid kits. MAST recommends you contact a qualified distributer of first aid equipment to see what best suits your boating needs. Remember to store your first aid kit where it and the contents will remain dry at all times and have the storage area well marked.
For those who do some fishing, it’s always wise to pack a thermos with hot water. Hot water is the best treatment if you are spiked by a gurnard or flathead. The hotter the water the better, but be careful not to burn the yourself or the person who is being treated.
Another common injury is a fish hook through a finger. Cut any fishing line, fish, bait, or lure from the fishhook. If the barb has penetrated the skin its best to seek professional advice when you reach shore.
And always make sure you have plenty of sun screen on board before you leave home.
