Superyacht Rig Monitoring Systems

Superyacht Rig Monitoring Systems

The Cyclops Rig Monitoring System delivers important information in an easily accessible manner, to help superyacht captains, management, builders and designers deliver an enjoyable, reliable experience for their owners and guests.  Using the latest technologies, our innovative Rig Monitoring Systems provide accurate data to help maintain safety and manage maintenance costs.




Superyachts are owned for enjoyment and prestige, and must always be ready to provide safe, reliable sailing for the owner and their guests.

They are expensive assets to purchase and operate, so must be operated efficiently and maintained diligently to minimise obstructions to any future sale. A critical part of the superyacht is the mast and rigging, a sophisticated structure which operates under very high loads throughout its lifetime. Rigging the mast is a complex process to ensure that the mast is properly supported, without over or under loads across the rigging.

To maximise the enjoyment and minimise the risk that comes with owning and operating a superyacht, confidence in the rig is essential for:

  • Captains concerned about the potential for rig damage or failure, causing expensive damage, taking the yacht out of commission, and risking injury to people.
  • Yacht managers concerned about planning efficient maintenance.
  • Potential buyers concerned about the value of the asset they are purchasing.

Cyclops can help to address each of these concerns, through our innovative superyacht rig monitoring systems.

The Cyclops Rig Monitoring System

From simple pen and ruler measurements, through to load pins and fibre optics, different technologies have been tried for measuring and recording the loads in a rig. None, however, provides accurate, repeatable data in a system that is both cost-efficient and easily retro-fitted, until now.

The Cyclops Rig Monitoring System has three main elements

  • a network of ‘smart fittings’ – load sensors integrated into fittings installed across the rig
  • a central IT hub which collects data about loads from the sensors, data about sailing conditions from the yacht instruments, and data about yacht motion and sea conditions from an integrated accelerometer
  • a personalised set of reports and interactive dashboards for the captain and authorised users, generated in the cloud using comprehensive data uploaded from the hub

Live instrument data

All smart fitting load data can be displayed live on the yacht’s instruments to help the crew sail the yacht, enjoying performance while maintaining crew safety and preventing damage to the rig.

The load data can also be connected to the yacht’s on-board PLC system for integrated alarm management and automated response.

Live instrument data

Digital rig logbook

Creates a permanent, cloud-based log for the yacht’s rig, recording usage, loads, and wind & sea conditions according to the hours and distance sailed. This can be shared securely with trusted partners.

Captain’s dashboard

An easy-to-use graphical display to help the Captain review and assess how the rig has been used and stressed. Information is presented numerically and in a series of interactive graphs.

Maintenance services

The yacht management team can authorise their preferred rigging company to access more sophisticated analyses in order to plan a more targeted and cost-effective maintenance schedule.

Industry views on rig monitoring systems


“For me and many other captains of modern performance sailing yachts mast and rigging load sensing is a welcome addition, particularly for owners wanting lighter masts without sacrificing the safety aspect.”

Captain Richard Allingham – Captain of SY BLISS and former Captain of SY Cinderella IV

“The load numbers are good when you have the sails set. 27 tons pressure on the forestay means I have to reef for example. And you can get closer to the max ”

Captain Fosse Fortuin – Captain of Schooner Atlantic and the former Captain on SY Ethereal


“As a rigging company dealing with a high volume of super yacht rigs annually, it is incredibly useful to have records of the loads that the spars and standing rigging have been subjected to. This data combined with the rig log is very helpful when completing rig inspections or undertaking refit projects.”

Steve Branagh of RSB Rigging Solutions SL. Based in Palma

“I would want every yacht to have a load monitoring acting as the ‘Riglog’? It’s an invaluable tool for both the yacht operators and the riggers to work with”

Eduardo Caro ‘Pachi’ of TRABAJOS EN CABOS S.L. – Specialist Riggers based in Palma ES

Value Protection

We all want the best for the Client and their Yachts, and in today’s world, Monitoring systems are a must for all Superyachts, so if you can have a Rig Monitoring system then it should be on the yacht. Will it help me achieve a better price or a sale against a Super Yacht that has not got a “Rig Service history” – I believe so.”

“A mast and its standing and running rigging have a finite life span even if well maintained and inspected. By logging the amount of usage either by sailing miles or hours (which may include sea and wind conditions), this will give the owner, managing agent or skipper an idea of when an inspection may be prudent, especially if such inspection ought to occur during a planned non-coastal voyage.”

Latest Marine Guidance Note of the 20th August 2019

Responsibility for making sure that a vessel is maintained to assure safe passage resides with the owner/managing agent while the Master (skipper) is directly responsible for undertaking voyage planning for individual passages. Owners, managing agents and skippers should, prior to undertaking a voyage, take all reasonable measures to… in the case of a sailing vessel, ensure that this assessment includes the mast, rigging and sails.”
