MED-TAC International's maritime first aid kits are built for boaters, offshore crews, dive teams, and coastal responders who face medical emergencies at sea — where EMS is minutes away on land and hours away on the water. These kits address USCG equipment requirements, offshore trauma management, marine envenomation, and dive medicine. Every kit is sourced from the original manufacturer or authorized distributor.
What First Aid Equipment Is Required on a Boat?
The U.S. Coast Guard sets minimum safety equipment requirements for recreational and commercial vessels under 46 CFR Parts 25 and 160. While federal regulations specify visual distress signals, fire extinguishers, and life jackets, the National Association of State Boating Law Administrators and USCG strongly recommend a dedicated first aid kit aboard all vessels. For offshore passages (greater than 3 nautical miles from shore), a more comprehensive kit covering wound management, airway supplies, and cardiac emergencies is essential. Commercial vessels operating under Coast Guard inspection must maintain a first aid kit that meets 46 CFR 160.041 standards. MED-TAC's maritime kits are configured to meet or exceed these thresholds while incorporating CoTCCC-recommended hemorrhage control components.
How Does Marine First Aid Differ from Wilderness or Urban Trauma Care?
Marine emergencies present a unique set of challenges not encountered in land-based response. Prolonged evacuation times — hours to Coast Guard rescue in offshore settings — demand higher-tier wound management and more comprehensive supply inventories. Environmental exposure requires waterproof packaging and corrosion-resistant hardware. Dive medicine considerations include decompression illness (DCI), arterial gas embolism, and near-drowning — conditions requiring specific oxygen delivery capability and rapid evacuation protocols. Marine envenomation from jellyfish, sea urchins, stingrays, and fire coral requires topical treatment supplies not typically found in standard IFAKs. MED-TAC maritime kits integrate these requirements alongside standard hemorrhage control and airway management supplies from our IFAK Kits collection.

What Is Dive Medicine and Why Does It Matter for Marine First Aid?
Dive medicine addresses the physiological effects of compressed gas breathing and pressure changes during SCUBA and freediving. The most critical dive emergencies are decompression sickness (DCS) — caused by nitrogen bubble formation during ascent — and arterial gas embolism (AGE), which can occur with breath-holding during ascent. Both conditions require 100% emergency oxygen administration and immediate evacuation to a hyperbaric chamber. Dive vessels should carry a demand-valve oxygen delivery system and maintain contact with the Divers Alert Network (DAN) 24-hour emergency line (+1-919-684-9111). Near-drowning management includes rescuer safety, early CPR, airway management, and hypothermia prevention — all covered by supplies in this collection and in our Airway Management and Hypothermia Prevention collections.
Why Are Waterproof Cases Essential for Marine Medical Kits?
Saltwater exposure degrades most medical supplies within hours if unprotected. Hemostatic gauze loses efficacy when the packaging is breached. Adhesives fail on wet skin. Electronic devices corrode. For vessels that may capsize, broach, or take on water, an IP67-rated or waterproof case ensures medical supplies remain functional for the emergency that matters. MED-TAC sources hard-case maritime kits with corrosion-resistant hardware and interior foam organization designed for salt environments. Complement your maritime kit with supplies from our Bandages & Dressings and Hemostatic Agents collections for resupply.

Frequently Asked Questions
Does federal law require a first aid kit on a recreational boat?+
Federal regulations under 46 CFR do not mandate a first aid kit on most recreational vessels, though commercial and inspected vessels have specific requirements. However, the USCG and all major maritime safety organizations strongly recommend one. Many state boating laws and charter regulations do require first aid kits. Regardless of regulatory requirement, the time needed for Coast Guard or EMS response in marine environments makes a well-stocked kit essential safety equipment.
What is the treatment for jellyfish stings on a boat?+
For most jellyfish stings (including box jellyfish), current evidence supports rinsing with seawater (not fresh water, which can trigger additional nematocyst firing), removing visible tentacles with forceps or a credit card (never bare hands), and applying commercially available sting relief preparations. For stingrays, immerse the affected area in hot water (as hot as can be tolerated) for 30–90 minutes to denature the protein-based venom. Seek emergency care for systemic reactions (difficulty breathing, swelling, anaphylaxis).
How do I treat decompression sickness onboard before evacuation?+
Administer 100% oxygen via a tight-fitting non-rebreather mask or demand-valve system immediately and continuously until evacuation. Keep the patient lying flat (not sitting up). Maintain hydration with oral fluids if the patient is conscious. Do not re-dive. Contact Divers Alert Network (DAN) at +1-919-684-9111 for real-time medical guidance and to coordinate hyperbaric chamber evacuation. Time to recompression is the most critical factor — oxygen administration is a bridge, not a definitive treatment.
What CoTCCC-recommended products should be in a marine trauma kit?+
A marine trauma kit should include CoTCCC-recommended tourniquet (CAT Gen 7 or SAM XT), hemostatic gauze (QuikClot Combat Gauze or Celox Rapid), a pressure dressing (Israeli Bandage or OLAES), a vented chest seal, and a nasopharyngeal airway (NPA). All should be stored in waterproof packaging. Marine environments increase the urgency for quality hemorrhage control because evacuation timelines are significantly longer than in urban settings — even a minor arterial bleed may not receive hospital care for 2–4 hours offshore.
How should I store medical supplies on a boat to prevent saltwater damage?+
Use IP67-rated hard cases or heavy-gauge dry bags with roll-top closures. Store cases in the driest, most accessible location aboard — typically a cabin locker accessible without opening hatches. Seal individual components (especially hemostatic gauze) in secondary waterproof bags. Inspect packaging every 3 months for seal integrity. Replace any item with compromised packaging immediately, regardless of expiration date. Salt air accelerates degradation even without direct immersion, so inspect all adhesive products (tape, dressings) at the start of each season.
What medical training is recommended for boaters and offshore crews?+
The Maritime Institute of Technology, DAN (Divers Alert Network), and the American Red Cross offer marine-specific first aid courses. For serious offshore cruisers and commercial crew, Wilderness First Responder (WFR) or Medical Person in Charge (MPIC) certification provides the most relevant extended-care training. All crew members on vessels traveling beyond VHF range should complete at minimum a Stop the Bleed course and basic CPR/AED certification. See our
Courses collection for available training options.
