Things to look for...

Broken Stands

"Proud" strands indicate broken strands in the swage fitting.

"Bird Caged Wire"

Corrosion and/or Cracked Swages


We can replicate your standing rigging in one of two ways:


  • You can drop off or ship your standing rigging to Lakeside Rigging, so we can 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.
  • You take the needed measurements and complete the supplied table. Please follow the given directions for measuring your rigging. All rigging 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 that is not measured by our rigging department.

1) If the mast is not unstepped yet, tape the threads at the turnbuckles. This will give you a mark to go back to after unthreading the turnbuckle to get the needed pin to pin measurement.

2) Determine the type of wire. See wire rope descriptions. Tables 1-5

3) Measure the wire diameter for each section. See figure 4.

4) Determine the pin to pin length for each section. See figures 5-7.

5) Determine the type of fittings. Note the pin sizes for each if applicable. See figures 8-9 .

If possible, note the manufacturer of the fittings, e.g., HAYN, CS JOHNSON, SELDEN, etc.

6) Determine the turnbuckle thread size by measuring the stud thread diameter. Note the thread count per inch and if left or right hand thread. See figures 6-7.

Continuous or Discontinuous Rigging

Continuous Rigging

The shrouds in continuous rigging run from the tang (the connection at the mast) over the spreader tip and to the deck. This eases spreader design and allows for all tuning to be done at the deck level.

It also reduces costs eliminating additional fittings required for discontinuous rigging.

Shroud identification differs from discontinuous rigging.

The drawing below shows both an upper (cap) shroud and the intermediate shroud passing over the spreader and continuing to the deck to meet the chain-plates.



Discontinuous Rigging

Each mast section is fitted with the size wire or rod to accept the loads generated at that section of the spar. Instead of traveling over the spreader, the wire or rod terminates at the spreader tip commonly known as a tip cup or other fitting. See example.

These are gradually reduced up the mast where the loads decrease. The result is less windage, lowered center of gravity,  and lower weight on occasion. Tuning must be completed at each spreader and deck level.

Shroud identification differs from continuous rigging.


Measuring Your Wire Diameter

Measuring Your Pin to Pin Lengths For Replacement


Lay out each section on a flat surface. Ensure that that section is tight and straight. Hold rigging in place using a nail (or similar) as an anchor point through the clevis pin hole, measure from the bearing point to the bearing point on the other end.  (Make sure to use a steel measuring tape that won't stretch.) Ensure there are no bends. Larger rigging components may benefit from using a trucker’s hitch to another fixed point to stretch the rigging taught.

Rod Rigging


 When working with rod rigging, we prefer to replicate the new rigging directly from the old rigging on our bench. This way, we can clamp the rigging down on our bench and get accurate measurements.


One of the most important sections of rod rigging is the Rod Head. These should be inspected at a minimum of every 5 years. Rod heads are formed by a hydraulic press and dies. The rod head is what keeps the fitting that attaches to a particular point on the mast or deck from coming off the rod.

See below for examples of rod heads.


Please keep in mind that a rod head inspection may force you to replace some fittings.

Some fittings easily allow for rod head inspection. These fittings are reusable. Some fittings are dimpled which lock the fitting in place and are not reusable. These particular fittings would have to replaced when performing a rod head inspection.

If it is found that a rod head has a crack or indication of a crack, in some instances, the rod could be re-headed without replacing the whole section of rod. Other circumstances, would warrant full replacement, such as when a rod shroud has a spreader bend fitting in place. The length from the spreader bend to the mast tang is a fixed distance and cannot be made up with a turnbuckle.

If the rod bent or kinked as below, we would also recommend replacement.
