3 harness lines, good condition. (The photo shows 5 lines, but 2 have been sold separately)
On Ariadne (our Rustler 36) we had 2 harness lines rigged at night, one at fwd end of cockpit so it could be attached before you came out of the hatch, the other fixed at the aft end of the cockpit for the helmsman. A third would be attached to the lifelines running along the deck so you could attach before leaving the cockpit. This meant that you could be attached to the boat at all times.
