J/109 Bobstay and Inhauler Upgrades


The J/109 class association recently amended the rules to allow for 2 significant upgrades. The first of which is a Dyneema bobstay.  This is a rope stay that suppors the spinnaker tack fitting, and prevents the carbon sprit from bending and losing luff tension-or much worse-snapping.   I’ve adapted the self retracting bobstay that was originally worked up for the J/111, and made some tweaks.  The retractor pulls the bobstay out of the way and keeps it from dragging in the water. Without a retractor, crew need to go forward and lasso the bobstay and hitch it to the bow cleat. The current bobstay version retracts inside the pole, and requires the addition of a bearing installed in the bow.

The second upgrade is for inhauling the class jib.  Our version has 8:1 purchase, and some really nice lead rings for doing the actual inhauling.  These are a huge upgrade over stainless rings in terms of friction and wear on sheets.  This is available as a kit that comes with the inhauler rings, control line blocks, cleats with extreme angle fairleads, control line, purchase line,  all fasteners and backing plates.  The kit itself is discounted from the total price of the individual items and will be $615.  If self installing it is critical that epoxy plugs and good backing be used for all hardware, but especially for the deck lead as the loads are considerable.

Please contact me if you have any questions,  having done this project I’ve picked up a few really important tricks.
