Easy repeatable Optimum Rigging Tensions.

A non-optimal rig will kill your chances to win your next regatta, especially in a one design race. But even worse: Contrary to popular thought, a slack rig is more punishing on a hull than a properly adjusted, tight rig.

Insufficient tension will not reduce the loads transmitted in the hull. Slack rigging will punish the spar and rigging needlessly by allowing excessive movement, chafe and shock loading. Modern fiberglass hulls should not be damaged by a properly adjusted, tight rig.

Figure 1 lists the rigging tension under different conditions for a typical boat with a properly tuned rig and with a slack rig. Note that the maximum loads do not exceed 900 lbs in this example. De overall maximum loads are the same with either a tight rig or a slack rig.

However, for properly tuned rig the leeward \ shrouds will not go slack under normal sailing conditions.

Figure  1.

The lateral stiffness of the mast and the fore and aft stiffness of the spreaders is reduced by a factor of 2 when the leeward shrouds go slack. This Important structural characteristic is not generally recognized.

Rigging tension is becoming more important as a result of the trend toward the use of mast bend to control mainsail shape under different wind conditions. Mast bend will also affect the shape and trim of the jib, since mast adjustment generally affects forestay tension. The expert skipper will benefit by maintaining consistent rigging tension while developing the optimum sail shape and sailing tactics.

Loos Cableware® Division offers a series of gauges to measure the tension in cables and rods from 2,5mm to 10mm . These gauges are designed for setting the proper tension in the standing rigging of sailboats and also for other applications such as supporting cables for radio towers, large tents and other structures. The gauges are relatively inexpensive and are designed to be suitable for rugged marine service. The “Professional Models” provide an increasing durability, accuracy and convenience of use when compared to our popular standard models. The gauge may be hooked on the wire and will remain in position while the tension is adjusted. Manufactured of rugged anodized aluminum, this gauge is corrosive resistant and will give years of service. Detailed operating instructions are included with each tension gauge.

Professional Models – Higher accuracy and easier to use than standard models. The cable can be adjusted while the gauge remains on the cable. “Just watch the pointer move.”  All readings are based on 302/304 1×19 S.S breaking strengths.

Partnumbers Metric Scale: PT-1M  for Cable Sizes:
2,5mm, 3mm and 4mm
PT-2M  for Cable Sizes: 
5mm, 6mm and 7mm
PT-3M   for Cable Sizes: 
7mm, 8mm, 9mm and 10mm

Rod Rigging Gauge

We offer a series of gauges to measure the tension in rods from .172 to .375 inch in diameter over a range of approximately 5% to 25% of the breaking strength of the rod and provide an accuracy of + or – 5%. The “Professional Model” RT series provides an increasing durability, accuracy and convenience of use. Manufactured of rugged anodized aluminum, this gauge is corrosive resistant and will give years of service. Detailed operating instructions are included with each tension gauge. Operates in the same manner as the Professional Model Series.

Partnumber RT-10M for Rod Sizes: 4,4mm, 5mm, 5,7mm, 6,3mm and 7,1mm
Partnumber RT-11M for Rod Sizes: 7,1mm, 8,4mm and 9,5mm
