Rigging Diagram

Use the diagram below to reference Harken part numbers to appropriate application on your J/105 sailboat. Parts recommendations are offered as a guide for common applications.

j105-mainsheet-rigging-img.gif

Gross-Trim, Fine-Tune Mainsheet

The divided cascading system runs the powerful fine-tune lead aft, allowing the helmsman to easily optimize sail shape on a light air beat. The gross-trim runs forward to the trimmer for fast mark roundings. To use this efficient system, simply add a 144 swivel base and third-party mainsheet adapter plate to your existing hardware.

MKIV Unit 1 Furler

MKIV's are easy to adjust for reefing and furling. When racing in non-class events, J/105 sailors can take the spool off and use the double-groove foil for fast sail changes.
