Attwood Marine Mooring Snubber Kit, 3/8 in x 20 ft Polypropylene Dock Line

Overview

The Attwood Marine 11730-7 is a mooring snubber kit with a 3/8 in x 20 ft dock line for boats that stay at a slip, tie up dockside, or ride against changing wake and wind. It pairs a flexible snubber with a blue solid braided multifilament polypropylene line, so the setup can take some of the shock out of normal mooring loads instead of passing that movement straight to the boat, cleats, and line.

For buyers checking fit, the included dock line is 3/8 inch diameter and 20 feet long. The snubber response can be adjusted by changing how much line is wrapped around it, which gives you a simple way to add or reduce give as conditions change through the day.

Key features

• Includes a 3/8 in x 20 ft blue dock line
• Dock line is solid braided multifilament polypropylene
• Flexible snubber helps absorb shock from wind, wake, and water movement
• Adjustment is made by increasing or decreasing the amount of line wrapped around the snubber
• Useful where the boat stays loaded against its mooring line instead of sitting still at the dock

Compatibility and fit

This kit is built around a 3/8 inch dock line, so it makes the most sense where that rope diameter matches the cleats, chocks, and fairleads already on board. The 20 foot length suits many short-run mooring and dock setups, but the right layout still depends on your boat size, freeboard, dock spacing, and how you rig each line.

It suits owners who want more give in a mooring setup without changing every line on the boat. On boats that stay in a slip or see regular passing wake, that extra stretch can help reduce repeated loading and make the boat ride a little calmer against the dock.

Installation and setup

The included line and snubber are meant to work together as one mooring setup. Once rigged, the feel of the system is changed by how much line is wrapped around the snubber, so you can set it up with a little more movement in protected water or a firmer response where the berth sees more surge.
