Cylindrical fenders just havent adapted to meet the needs of boaters today. Sport boats no longer have flat sides, handrails, and high-waisted rub rails, for example. This makes it extremely difficult to position a protective fender effectively between a boat and dock. With this dilemma in mind, we set out to create the best boat fenders that look great and protect your boat.• Hugs contours, for better perfection - SENTRY fits modern boats better - protecting both above and below the rub rail• Stays put - The no-roll shape keeps your fenders right where you place them• Do more with less - The innovative shape and material provide impact protection than traditional cylindrical fenders• Always in lockdown mode - With our new LockCAM your fenders are always locked into place. The lock won't let the strap slip until you release it with the lever• Fits better - The hanging point of SENTRY is lower than it is with traditional boat fenders• Pass-through access - The large opening in the face of the fender creates a hole for dock lines to pass through in situations where the fender covers the boat cleat• A little help, please?! - Now anyone can help during docking.
