Rub Rail Integrated Fender System
Rub Rail Integrated Fender System

Protection, built in.

An inflatable boat fender concealed inside the rub rail. One press at the helm and it rolls out along the hull. Release, and it retracts out of sight.

Invisible when stowed. No loose fenders. No lines over the side. Nothing on deck. When you don't need it, the boat looks exactly as its designer intended.

Docking is the one moment that hasn't moved on.

Wind up, hands full, and someone still hanging fenders over the side. Sentinel takes that moment off the list.

In plain terms

What is a rub rail integrated fender system?

Sentinel RIFS is an automatic boat fender. Instead of hanging inflatable fenders over the side on lines, one inflatable fender lives inside the rub rail along each side of the hull. At the helm you press once: it inflates, rolls out and covers the full length of the rail. Release, and stainless springs draw it back in. It is not a fender holder or a fender basket — there is nothing to hold, because nothing is loose.

Automatic, from the helm

No walking the side deck, no leaning over the rail. Deploy and stow from the seat you steer from.

Retractable, not removable

Retractable boat fenders that stay on the boat. Nothing to stow in a locker, nothing left on the dock.

Refit for boats of 6–12 m

Motor yachts, cruisers and sloops with a rub rail. Fitted to existing boats or specified on new builds.

Questions

The short answers.

Will it fit my boat?

Sentinel is designed for boats from six to twelve metres. Every installation starts with a measure-up, so fit is confirmed before you commit to anything.

Can it be fitted to a boat I already own?

Yes. Sentinel is designed for refit as well as new build. The system is fitted to the rub rail; the assessment tells us what your rail needs.

How is it operated?

From a single control at the helm. Press to deploy, release to stow. It runs from the boat's onboard electrical system.

How is this different from ordinary inflatable or automatic boat fenders?

Ordinary fenders hang from the rail on lines and have to be placed, tied and stowed by hand. Sentinel is built into the rub rail itself: one continuous inflatable fender per side that deploys from the helm and retracts on its own, so nothing is hung, tied or stored.

What happens when it's not in use?

It retracts behind a sealed closure in the rub rail. Nothing on deck, nothing over the side, nothing to put away.
