Dock Edge 12′ Mooring Whip Model 3400-F

Keep your boat safely away from the dock with the Dock Edge 3400-F 12′ mooring whip. Mooring whips hold your boat off the dock face using a pair of flexible fiberglass poles and bungee lines absorbing wave action, wakes, and tidal movement without letting the hull contact the dock. The result is less hull wear, fewer fender marks, and a boat that stays in position even in busy marinas or exposed slips.

The 3400-F is a 12-foot fiberglass whip designed for mid-size powerboats and sailboats. The fiberglass pole flexes under load and returns to position, providing continuous, passive protection without any adjustment required. Sold as a pair for complete port and starboard coverage.

Best Use Case

Best suited for boats in the 2035 ft range docked in slips or alongside docks where wave action, wakes, or tidal movement cause the hull to repeatedly contact the dock face. Mooring whips are particularly valuable in marinas with heavy boat traffic or in exposed locations where conventional fenders alone arent enough to prevent hull damage. Mount the whip bases to the dock at the appropriate spacing for your vessels beam, attach the bungee lines to the bow and stern cleats, and the system handles the rest. Confirm the whip length and rated boat size against your vessel before ordering.

Parts Desk Insights

Mooring whips are a strong upsell for any customer purchasing dock lines, fenders, or mooring accessories especially customers who mention hull damage or fender wear from dock contact. At $821 this is a considered purchase, but the value proposition is easy to communicate: one season of prevented gelcoat damage pays for the whips. Always sell in pairs (port and starboard). Cross-sell the Dock Edge Mooring Snubber for customers who want additional shock absorption on their dock lines, and the Dock Edge Full Face Bumper 4-1/2″ x 8′ for customers who also want dock face protection. For fender lines to complete the docking setup, see the Sea-Dog Fender Line 1/4″ x 6′ Black, Blue, and Gold Braid.
