Built by a Sailor. For Sailors.
The ParkN Clamp started with a problem every ISCA sailor knows: how to install a cleat on the mast without drilling into it or compromising the mast’s integrity.
How It Started
1.5 Years. Dozens of Prototypes. Zero Compromises.
Parker Nagle is a youth ISCA sailor from St. Croix, USVI. Like every sailor in the class, he kept running into the same problem: attaching fittings to the mast meant drilling — and drilling meant corrosion, weakened mast walls, and a broken mast waiting to happen.
Parker spent 1.5 years designing, testing, and refining prototypes alongside his dad, David Nagle — a degreed Aerospace Engineer. Every iteration was tested in real conditions on the waters of St. Croix, with Parker and fellow ISV ISCA sailors helping put the clamp through its paces.
Those prototypes have already competed at the 2025 ISCA North Americans, the 2025 ISCA World Championships, the 2026 ISCA North Americans, and the 2026 CAC Games. The ParkN Clamp isn't a concept — it's a proven piece of racing hardware.
Proven on the Race Course
From Prototype to World Championships
Prototypes of the ParkN Clamp have been used at four major ISCA events by Parker and fellow ISV sailors. This isn't lab-tested hardware — it's race-tested hardware.

Our Mission
Better Gear for the ISCA Community
We're not a big marine hardware company. We're sailors helping sailors who are frustrated with the available options and decided to make something better. The ParkN Clamp is designed specifically for ISCA mast specs — not a generic solution adapted to fit. Every detail, from the clamping geometry to the hardware grade, was chosen with ISCA racing in mind.
Community First
Designed by an ISCA sailor, tested by ISCA sailors on the waters of St. Croix. We build for the community we race in.
No Compromises
Marine grade materials only. SLS Nylon 12, 316 SS hardware, and a rubber grip insert aren't the cheapest options — they're the right ones.
Simple by Design
The best solution is the one you can install yourself, on the dock, before a race. No special tools, no drilling, no drama.
