Whether you're enjoying a day of sailing, kayaking along the coast, or paddleboarding on a lake, accidents on the water can happen when you least expect them. A well-prepared boat first aid kit is essential for dealing with cuts, burns, slips, sun exposure, and other injuries that may occur away from immediate help. This UK-focused guide explains why first aid kits are important on the water, what the regulations say, and what essential items you should pack.
Boating and water activities present unique risks — from slippery decks and fishing hooks to long exposure to sun and wind. Emergencies at sea or on inland waters can be more serious because help often takes longer to arrive. Having the right equipment onboard lets you treat injuries quickly and stabilise the situation while waiting for professional help.
In the UK, commercial vessels must comply with Maritime and Coastguard Agency (MCA) requirements, which set minimum carriage levels for medical supplies depending on the vessel type and distance from shore.
For recreational boats, there is no strict legal requirement to carry a first aid kit. However, organisations such as the RNLI and Royal Yachting Association (RYA) strongly recommend having a well-equipped kit on board. Following BS 8599-1 workplace standards is a good starting point, adapting contents for the marine environment.
Below is a list of useful items to include in your boat’s first aid kit. These items cover common injuries like cuts, burns, seasickness and hypothermia. Ensure all contents are stored in a waterproof container or dry bag to protect them from moisture.
| Item | Why It’s Needed on Boats |
|---|---|
| Waterproof first aid container | Keeps all supplies dry and usable in marine environments |
| Sterile dressings and bandages | Treat cuts, fishing hook injuries, scrapes and small wounds |
| Burn gel or dressings | For sunburn, galley burns or cooking accidents onboard |
| Saline solution | Rinse eyes or wounds affected by salt water, sand or debris |
| CPR face shield or mask | Safer CPR in emergencies, especially in remote areas |
| Whistle and waterproof torch | Useful for signalling and night-time emergencies |
| Foil blanket | Helps prevent or treat hypothermia after immersion |
| Scissors and tweezers | Remove splinters, trim dressings and manage minor injuries |
| Gloves | For hygiene and protection when giving first aid |
| Seasickness tablets | Alleviate motion sickness, which can worsen emergencies |
| Emergency contact list | Key numbers (Coastguard, medical) stored in a waterproof pouch |
