Bungie Cord & Lacings
Assuming you have upper and lower life lines; starting at the bow pulpit, use some 1/8" braided nylon cord tied to the toe rail, then diagonally up to the lover life line then diagonally back down to the toe rail, forming 'triangular lacings all the way back to the second staunchion base. AThen starting from the first lifeline and diagonally rising to the upper life line, create a similar set of triangular lacings tha t mirror your lower life lines.
Second, run 3/16" bungie cord lengths from the bow pulpit to the 1st staunchion base with a nylon 'hook' tied in at the middle of the bungie chord. You should adjust the length so when you pull up on the hook and attach it to the top life line there is slight tension in the bungie chord. Repeat between the 1st and second staunchions. When you drop a headsail along the rail, the lacings keep it on board and the bungie chords can be pulled out and wrapped over the flaked sail and re-attached to the lower lifeline to hold the sail on deck. works great with a Headfoil system and racing Genoa's.
