Mooring Line and Anchor Snubber sizes

Which size should I need to mooring or anchoring my boat?

    We have received many requests asking about the right line size for mooring and anchoring boats.

The right rope size depends on a number of factors: strong winds, waves, boat length, tides and quality of the rope.

The following information is intended as a recommendation/guide only, based on the mooring line and anchor snubber standards of dbropes (made with 100% three-strand nylon ropes made in USA).

MOORING LINES

Boats Length Up: 18 ft 3/8" diameter.
Boats Length Up: 24 ft 1/2" diameter.
Boats Length Up: 29 ft 5/8" diameter.
Boats Length Up: 40 ft 3/4" diameter.
Boats Length Up: 55 ft    1" diameter.

ANCHOR SNUBBERS

The length should be equal to 2 1/2 times the freeboard (the height of a ship's side between the waterline and the deck).

Boats Length From 20' Up: 35' = 1/2" diameter.
Boats Length From 36' Up: 45' = 5/8" diameter.
Boats Length From 46' Up: 59' = 3/4" diameter.
