When it
capsizes,
they hold on.
CapSure is the world's first automatic hull handle system - factory-installed, gravity-deployed, and ready the moment a watercraft overturns. Zero drag. Zero maintenance. Just survival.

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.
Built to deploy
in seconds
A purely mechanical system that requires no human intervention - because in a capsize event, seconds matter and people are already in the water.
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.
The moment the watercraft overturns, gravity automatically releases the handle from its stowed position and swings it outward into a horizontal grip position through the cavity opening. No electronics. No sensors. No manual activation required. Physics does the work instantly.
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.
A safety feature
your customers
can't get anywhere else.
CapSure is 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 seeking exclusive OEM territory partnerships with leading boat manufacturers. The technology is proven. The opportunity is open.
Integrated at build. Shell and hull surface become one continuous piece.
Flush cavity design creates no hydrodynamic penalty in normal operation.
Chemically bonded flange seals the system. No water intrusion. No bilge risk.
21-claim US patent issued January 2024. Exclusive territory licensing available.
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.
Test the existing prototype on your vessel. Evaluate deployment timing, grip ergonomics, cavity sealing, and hull integration quality.
We work with your engineering team to adapt the shell geometry to your specific hull materials, lay-up schedule, and production process.
Exclusive territory licensing available. Per-unit royalty structure with volume pricing. Full IP protection transfers to your production line.
Partner Ready.
CapSure is protected by US Patent 11,873,061 B2, issued January 16, 2024, by inventor James Salmela of Palm Bay, Florida. The patent covers 21 claims spanning the handle system, deployment mechanism, cavity construction, and watercraft integration methods.
