How Much Line?

Genoa sheets are generally 1.5 times the length of a boat. For non-overlapping jibs, one boat length is usually enough. Spinnaker sheets are usually twice the length of a boat. We recommend measuring all other running rigging.

Finally, We've included a Metric Conversion Chart to help you along.

Also, you should take a look at Choosing Your Halyards and the New England Ropes' Line Stretch Graph.

Wire Halyard Replacement Guide

Rope halyards are easier to handle and significantly lighter than wire halyards. Sta-Set X is an ideal replacement for wire halyards on cruising yachts. For race boats and large cruising yachts, use Spect-Set II or T-900
