J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment mast partners

I would like to know what various owners have used as chocks at the past partners. Any info on materials, techniques of installation, etc. would be appreciated.
TIA

Spartite. Follow the instructions that come with it. Rig some blocks and a line led to a winch to pull the mast forward a 1/4" or so, so that the Spartite gets all around the mast. After a half hour or so, relax the tackle so that the mast moves aft in the opening to its normal position.

Made adjustable mast blocks out of HDPE like are used on Lightnings and other dingies. Lets you tweak position easily. Covered with boot from West Marine. Had to open the partners aft to get mast to full back position, but that's another story.
