Size by stay length
Worked from the method on the sizing page. Final measurements must be taken on your own boat after the furler is installed and tensioned. Call 904-600-4105 and we will size it with you.
Standard range
15 to 55 feet, 1/8 to 3/8 inch wire.
Our standard sizes cover any stay length from 15 to 55 feet and wire diameters from 1/8 to 3/8 of an inch. Larger sizes are a custom fit — call and we will work it out with you.
Systems are sold by the foot, so you pay for the length your rig actually needs instead of a boxed kit and a pile of offcuts.
Don't have the measurement yet?
The sizing page walks through taking it on deck with the mast up, using a jib halyard and a messenger line.
