As both a trauma surgeon and a USCG-licensed captain, I have seen firsthand the types of injuries that can happen on the water. While boating accidents can be severe, the majority of injuries are manageable with the right first aid supplies. That’s why I’ve fine-tuned my standard marine first aid kit with a few essential upgrades. Because when an emergency strikes, having the right gear can mean the difference between a quick recovery and a dangerous situation.
Lacerations and Bleeding: Keep to the Basics
Small cuts and scrapes happen all the time while fishing or boating. Most kits come stocked with antiseptic wipes, bandages, and butterfly dressings—but what if the bleeding is more severe? Here’s what I add for wound management:
Kerlix® Rolled Gauze – Absorbent, long cotton gauze perfect for packing wounds and holding pressure. Although most marine first aid kits may have rolled gauze, I add the bigger 4 inch rolls.
QuikClot® Combat Gauze – Infused with kaolin, a clotting agent that accelerates blood coagulation, ideal for serious wounds.
Tourniquet – A Combat Application Tourniquet (C.A.T) is a must-have. If direct pressure doesn’t stop the bleeding, applying a tourniquet high and tight above the wound can save a life. However, correct placement is critical—a loose tourniquet can make bleeding worse.
Pro Tip: One of the biggest mistakes people make when managing heavy bleeding is lifting the dressing to check the wound. This disrupts clot formation. Instead of removing a soaked bandage, layer additional gauze on top while maintaining pressure.
Bone Fractures: Stabilization Matters
Rough waters and slippery decks can lead to falls—sometimes resulting in painful fractures. If an injury leaves a limb deformed or broken, stabilization is key until you can reach medical help. Here’s what I rely on:
Large Elastic Bandage – Elastic compression bandages help manage swelling and provide support. Some kits have ACE bandages, but I always add the 6 inch variety.
Splinting in a Position of Comfort – Immobilize the limb in a way that minimizes pain. Movement can worsen the injury, so securing the area properly is critical.
Cold Exposure: Hypothermia is Deadly
Cold water can be deadly. In 40-degree Fahrenheit water, unconsciousness can set in less than 30 minutes. That’s why rapid warming is crucial. One of the simplest yet most effective tools is:
High-Quality Mylar Thermal Blanket – These foil blankets trap body heat and shield patients from cold air exposure. Removing wet clothing and wrapping them in a Mylar blanket can be the first critical step toward rewarming.
Final Thoughts from a Trauma Surgeon and Captain
A well-stocked, waterproof marine first aid kit is one of the best safety investments you can make for yourself and your crew. I’ve shared a few upgrades based on my experience, but ultimately, basic first aid techniques remain the most important life-saving skills. As a USCG-licensed captain, I am required to maintain CPR and first aid certification, and I highly encourage all boaters to do the same. Because in an emergency, knowing how to act quickly could save a life.
Tight lines and smooth seas,
Captain (and Doctor) Joe
