This comprises our standard boom track slide and a specially shaped hook that a loop on the end of the sheet attaches to. Lock the sheet attachment where it gives the correct sheeting angle and you can guarantee that you will get exactly the same sheeting position next time you rig the boat. If you want to adjust the boom angle you can adjust the sheet attachment position by the smallest amount by slackening the socket screw and re-tightening.

The advantages over the zed hook, item 87z, are: no holes required in boom, point of corrosion avoided, repeatable positioning without recording the hole used, infinitely variable.

All SAILSetc spar section boom kits and completed booms for IOM will have this item provided as standard.
