"The “Remote guided engineering support” provided [under covid-19 pandemic travel restrictions] was invaluable. Without it, we would never have been able to achieve our charter obligation. I cannot thank you enough." Captain MY Monaco, 37m Feadship built motor vessel.


"Thanks so much for your help, really fantastic service and reporting. Great job. We will have some more projects for you when we return to Palma next year." Captain of Alloy Yacts 37m, SV Genevieve


“ Andy designed and installed a completely custom GSM, SMS / Email alarm and monitoring system, integrating it into our existing (20 year old) PLC based on board system. We now have a reliable and functional SMS system that the engineer and I have a lot of confidence in.

It was a pleasure having Andy work on board and I would have no hesitation asking Andy to work on board again."  

Captain of SV Anakena, 40m luxury sail super yacht built by Royal Huisman. 

“I would like to say that Andy Ridyard and his company SeaSystems has to be one of the best contractors that I have had the pleasure to work with in a long time. Andy’s commitment to trouble shoot, fault find and most of all to see the job through to the end is an attribute you unfortunately rarely find nowadays. I cannot recommend him and his company highly enough.”

Chief engineer of the Red Dragon, 170' sloop.

“A rare find in modern superyachting, an independent with good knowledge and a sensible hourly rate – thanks for your help Andy, greatly appreciated.”

Chief engineer of the Timoneer, 146' luxury ketch.


"We have an SMS telemetry system on board our yacht that had failed due to power surges and blackouts during the summer. Andy came on board and installed a new system for us which now works perfectly. I enjoyed having Andy aboard, he was very knowledgeable and guided me through the whole process allowing me full access and understanding of the system. Andy was readily contactable for any questions and support whenever I needed it. I look forward to working with him again."

Chief engineer of Clan VIII, 2011 148' sloop

“Andy Ridyard has improved the work of these PLCs significantly since he has been involved with us, to an extent where his work has by far exceeded that of our build yard. Thank you Andy, for all the hard work to resolve this list of issues which have been with us for some time!”

Skipper of Windrose of Amsterdam, 2002 Dykstra-designed 152′ aluminium spirit-of-tradition racing schooner.

He’s very meticulous, knowledgeable and up to date in all electronics and electrical systems and his documentation relating to the work he’s done is invaluable.”

Skipper of Hamilton 2, 118′ CNB super-maxi.

“You have a wonderful high tech business and you do a great job… At last we’ve got those 3 phase generator and shore power issues resolved and we are back to how the boat was originally supposed to work, along with new and updated drawings, plus continuing documentation"

Skipper of M/Y Atlantide, 120', 1930 classic gentleman’s motor yacht.

“On a personal note I find Andy to be an honest, reliable and very professional person with a very high standard of work ethic.”

Skipper of S/Y This is Us, 2005 Hoek-designed 143′ aluminium spirit-of-tradition racing schooner.

“After four years onboard as skipper we have had several well recognised electrical engineers look at our generator load sharing/ syncing issues with limited success. Andy came onboard and within a week had identified and solved the underlying issues. My engineer and I found Andy to be extremely pleasant to have onboard, competent and knowledgeable and I am sure that his experience in the industrial world more than qualifies him for the ever increasing complexity of Superyachts. I would not hesitate to use Andy’s services again or recommend him.” Skipper of S/Y Moonbird, Dubois designed 120' sloop.

“The system was down for quite some time and neither the two companies we hired in Italy nor the technicians we met along the way could find the fault...  Andy managed to find the fault, design and rebuild the electronic part that was no longer available, and install it. We were very lucky to meet him in Antigua and I strongly recommend him to anyone having insolvable issues.

“Thanks again Andy.”

Skipper S/Y Oceans Seven Squared, 105' sloop, built 1998.
