Types of Lifeline Construction
In general, there are three types of lifelines.
- 7 x 7 Wire with a white vinyl coating. This is easier on the hands due to the increased diameter but tends to discolor with age. One is also unable to check the condition of the wire under the coating.
- 1 x 19 Uncoated Wire. Somewhat harder on the body while hiking, but easier to inspect. Does not discolor in the sun.
- Dyneema lifelines. Lighter and stronger than the wire, but subject to chafe.
Sizing Your Wire (Minimum Requirements)
Up to 28' LOA.......................1/8" wire
28-43' LOA..........................5/32" wire
43' LOA and up....................3/16" wire
Cruising sailboats, of course, are not subject to these requirements, but can still be used for reference. Some boats have smaller diameter wire installed for the lower lifelines for weight savings.
Replicating or Measuring For Replacement
We can replicate your lifelines in one of two ways:
- By dropping off or shipping your lifelines to us, where we would then replicate it by laying each section on our bench to get the measurements needed. This is usually the best way and can reduce a certain amount of confusion and mistakes.
- By taking the measurements needed yourself and filling out the supplied table. Please follow the given directions for measuring your rigging. All lifelines will be made to the measurements that you provide to us. Please take all precautions to take accurate measurements as there are no returns on standing rigging or lifelines that is not measured by our rigging department.
See below for examples of differing situations, and specific measuring requirements. These are due to gate placement.
A = Distance from bearing surface of bow eye to the bearing surface of the stern eye.
A = Distance from bearing surface of stern eye to the bearing surface on gate side of stanchion.
B = Distance from bearing surface on inside of gate stanchion to bearing surface on inside of gate stanchion.
C = Distance from bearing surface on gate stanchion to bearing surface on bow eye.
A = Distance from bearing surface of stern eye to the bearing surface of the aft gate stanchion.
B = Distance between the aft gate stanchion bearing surface and bearing surface of the bow eye.
