Most rigs are tuned by dock tension and feel. Under sail the loads change, and one stay often works harder than the others

This survey measures the real loads on the standing rigging during a sea trial, using sensors fitted for the outing. It shows which stays are working harder, whether the trim is balanced between sides and between verticals and diagonals, and how the rig is actually loaded in the conditions you sail

Measured at sea

A sea trial of 2–5 hours measures the loads on that outing. Dock tensions, the stay that carried the highest repeated load, and whether the trim is balanced between sides and between verticals and diagonals.

This boat only

The outing covers the wind and the sailing that were recorded. Using your sailing profile we can also estimate a conservative range for harsher conditions or more hours in the same style of sailing. Conditions not measured are listed and treated more severely. It does not transfer to a different rig. A sister ship is a different rig.

Sailing time before inspection

From the measured outing we also estimate a conservative range of sailing time before the next inspection, for the conditions sailed. The maker’s interval, or the insurer’s, still applies. Whichever comes first. It can only bring an inspection or replacement forward, never postpone it.

Our Core Services

Crack assessment

This step starts only when an inspection has found a crack, or a suspect fitting, and the report is on the table. The sea trial does not look inside a part. No report, no crack step.

Crack assessment

Dynamic Analysis

  • Specialist simulation of vibration, shock and transient loading for marine, defence and industrial structures.

Also available

We also undertake static structural and mechanical FEA simulations, and SolidWorks geometry preparation, when it supports a fatigue, crack or dynamic decision.

Composite design and delamination analysis is under development and can be discussed for suitable future projects.
