When it
capsizes,
they hold on.

CapSure is a patent-protected hull handle system for OEM boat manufacturers. Factory-installed, gravity-deployed, and built to help people stay with the vessel when seconds matter.

Smooth hulls
cost lives

Boat hulls are engineered for hydrodynamics - smooth, continuous, frictionless. That's by design, and it serves the vessel well. But when a boat capsizes and occupants are thrown into the water, those same smooth surfaces leave them with nothing to hold onto.

The watercraft is the most visible object at the scene. Rescue teams find vessels, not swimmers. Remaining with the vessel dramatically improves survival odds - but with no way to hold on, people separate, drift, and disappear. Had they been able to hold on, many would have survived until help arrived.

The Technology

Built to deploy
in seconds

A purely mechanical system that deploys on its own when seconds matter. No buttons. No power. No delay.

01
Underway

Handle stows horizontally inside a sealed, watertight cavity - completely flush with the hull exterior. No protrusion. No drag. No turbulence at any speed. The vessel performs exactly as designed.

02
Capsized

The moment the watercraft overturns, gravity releases the handle from its stowed position and swings it outward into a horizontal grip position. No electronics. No sensors. No manual action. Physics does the work instantly.

03
Survival

The grip handle is presented to anyone in the water. They hold on, stay with the visible vessel, and remain anchored to the only object a rescue team is likely to spot from any distance.

State Diagrams
From stowed to deployed - automatically
Upright
Handle down, tucked into the cavity. Zero drag.
Capsizing
Gravity swings the handle outward while keeping it horizontal.
Deployed
Handle folded out horizontally from the hull above the waterline. Ready to grip from water.
For Boat Manufacturers

A safety feature
your customers
can't get anywhere else.

CapSure is a veteran-founded safety technology designed from the ground up for OEM integration - molded into the hull at manufacture, it becomes part of the vessel itself. Not an add-on. Not an accessory. A native safety feature that differentiates your line.

With a prototype ready and US Patent protection in place, CapSure is looking for OEM partners who want a built-in safety feature that clearly stands apart.

Factory Molded

Integrated at build. Shell and hull surface become one continuous piece.

Zero Drag

Flush cavity design creates no hydrodynamic penalty in normal operation.

Watertight

Chemically bonded flange seals the system. No water intrusion. No bilge risk.

IP Protected

21-claim US patent issued January 2024. Exclusive territory licensing available.

OEM Integration Path
1
Initial Consultation

We review your hull designs and identify optimal placement - typically above the waterline on the hull exterior, ensuring access in both capsized and upright states.

2
Prototype Evaluation

Evaluate the current prototype on your vessel. Review deployment timing, grip ergonomics, cavity sealing, and hull integration quality.

3
Custom Engineering

We work with your engineering team to adapt the shell geometry to your specific hull materials, lay-up schedule, and production process.

4
License Agreement

Exclusive territory licensing available. Per-unit royalty structure with volume pricing. Full IP protection transfers to your production line.
