J/70 Jib Halyards & Fine Tune
Our J/70 Jib Halyards are low stretch and high performance, built to class minimum diameter. All halyards are two piece (primary halyard line and hoisting tail) and feature a reeving eye at the working end and an end whip at the end you tie off to the sail. Vectrus offers lower creep over time compared to Amsteel, but is less UV stable. Our fine tune line is made from either Endura Braid or Dinghy Control for minimal stretch and ease of handling.

J/70 Spinnaker Sheets
Our J/70 Spinnaker Sheets are hard wearing for top performance and utilize high end line options. We strip and taper the sheet on each end, joining the core to two Amsteel Dyneema pig tails to luggage tag onto sheets and tie onto the spinnaker. Rigged continuous through the boat, the polyester cover offers great grip and durability for sheeting.

J/70 Clew Blocks
Our J/70 Clew Blocks are all great options depending on preference. The first option uses smooth running ball bearing Harken 40mm Carbo T2 Blocks that provide easy adjustment under load. Their composite construction protects the mast from dings. The second option is built the same way, but utilizes 14mm Harken Lead Rings that offer low friction and less moving parts. Both are designed to be luggage tagged to your jib.

Use the diagram below to reference Harken part numbers to appropriate application on your J/70 sailboat. Parts recommendations are offered as a guide for common applications.
The 493 Underdeck furler lowers tack height, maximizing sail area. A ball bearing swivel on the headstay, allows you to raise/lower the jib or adjust luff tension. The jib halyard exits the mast and attaches to a 40 mm 2621 Carbo fiddle; the control line leads through a 40 mm 2148 T2™ Loop block and adjusts using a 396 29 mm Carbo Pivoting Lead block with Carbo-Cam.
The 5:1 mainsheet system features 2148 and 2151 Carbo T2 blocks that hang from a Dyneema® strop attached to the boom. A 2621 57 mm Carbo fiddle rides on the traveler car. A 57 mm 2135 Carbo ratchet atop a 144 swivel base finishes the system. The switchable ratchet allows the skipper to turn the ratchet off in light air, or on when grip is needed.
A 40 mm 2156 Carbo® Pivoting Lead block attaches to the back of the mast. The spinnaker halyard exits the mast at centerline, runs through the 2156, and cleats at a 150 aluminum cam. The 2156 has a weight savings of almost 20% over the stainless version it replaces without sacrificing load capacity.
