OOPArt Cleat

OOPArt cleat made from mirror polished cast AISI 316 stainless steel. This cleat is named after the archaeological abbreviation for Out Of Place Artefacts (OOPArt), a term referring to artefacts discovered out of context or in unexpected locations. It is so named because this cleat has a unique hollow design that enables multiple uses, normally impossible with traditional cleats. Because of the ingenious design it can be used as a cleat, a fairlead, a ring, an eyebolt, a pad eye and a mooring point. Several functions can be performed at the same time. The hollow design allows the user to make more types of knots and to untie them more easily pushing the rope from the bottom. Easy installation with above deck fastenings makes this a must-have addition to any vessel.

What size cleat do I need?

The size of cleat you should use depends on the size of line you use; and in turn the size of line you use depends on the size of your boat. As a general guide you can use the following equation to calculate the approximate size of cleat that you should be using:

Cleat length from end to end should be 1″ for every 1/16″ of line diameter; and dock lines should be 1/8″ of diameter for every 9 feet of boat length.

This will give you a good idea of what size cleat to use as a minimum; but remember bigger is often better and you may want to use the same cleat for more than one line at certain times, so be sure to give yourself enough capacity to be flexible. This model is available in two sizes: 160mm (6 1/4″) and 200mm (8″).

Cleats should be positioned at regular intervals along the port and starboard sides of your boat. As a basic guide you should have at least a minimum of three on each side (at the stern, bow and amidships), and again the more you can reasonably accommodate the easier you will make your sailing experience.
