OX7HI3 – Harken hook-in block Optimist

These grey sprit ends are suitable for the Optimax MK3 and Optimax MK3 Flex sprits. Sold per pair.

The Optimax Optimist deck collar is made of Delrin to create minimal friction between the sleeve and the collar. The oval inner diameter allows the maximum fore/aft and minimum side play and the tapered inner diameter allows the mast to be raked. 4 countersunk mounting holes. Hole size in deck: 57 mm.

The mast sleeve is fitted around the mast at deck level and protects the mast from wearing. Optimist mast sleeve as supplied with Optimax spars.

Mounting the sleeve – you will notice the sleeve is slightly smaller than the mast. To mount the sleeve you should gently warm the sleeve with a hairdryer or paint stripper. You can easily slide the warm sleeve over the mast into position.
