Whats Our Customers Are Saying

Don’t just take it from us, let our customers do the talking!

Dear Andrew,

An absolute pleasure!

We met Andrew in 2013 and were impressed by his work ethic and his professionalism. In the five years that we have worked together on our beautiful Oyster 55, he and is team have consistently delighted us with their first class service and their engineering prowess.   No job is too small, or too large, from replacing a passerelle shackle to installing a new engine and generator.  All delivered with courtesy. I would not hesitate to recommend his service, and Shearwater is a fine testament to their work. 

With love to all


Owner of Oyster 55


Andrew and his excellent team at Sentinel (now Berthon Spain) have been looking after my Discovery 55 in Palma for 3 years now. He has demonstrated his knowledge, engineering expertise, pragmatism and cost efficiency in everything that he has done for me and he runs his business with high integrity and a great service attitude. I have no hesitation in recommending him and his people to any yacht owner who cares about the quality of service they receive.

Many thanks

Peter Smith

Owner of Discovery 55 SY Kingfisher

Hi Andrew,

I just wanted to say a huge thank you for all your help and for getting the boat into such great shape. Yours, and your teams help is much appreciated! I am delighted to say that Jo is really enjoying the boating experience which bodes well for the future - fingers crossed!


Owner of Oyster 56 SY Moana

Hi Andrew,

Brilliant! Huge thanks to all.
When the boat was launched these seats where the biggest rave item on the boat. There is a huge kudos thing with this. The boss will be laughing his way all around the world!!

Big thanks.


Captain of SY Atares Royal Hauseman 55m

Thanks Andrew,

You’re the best guardiennage we have ever encounterd.

Your efforts will certainly help us sell Proteus and when we do,  we look forward to have our new yacht looked after by you as well.

A very big thank you.

Denise and Chris

Owner of Oyster 655 SY Proteus

Our beautiful yacht Amitié is just like a great woman – exciting, beautiful, stunning. But – you may know it already - it takes a lot of time, effort and care to "make her happy".  

Without Andrew, I would certainly be desperate sometimes. He is not just very reliable and works fast enough to cope with an impatient man like me, yet he is very careful.

I find it equally reassuring and impressive how ingenuity Andrew always finds solutions to all complex and new problems. He's the only one I know who invented the perfect treatment method for stainless steel. He will always be the right person - for winter storage, repairs, details of beauty or other issues that may arise. Time to say: Thanks. With absolute recommendation.

Many thanks

Burkhard Grassmann

Owner of Gunfleet 58 SY Amitié

Hi Andrew,

 Thank you for the service.

Everything works perfect and we have wonderful day on our yacht!

I'd also  like to thank you very much for the cool beer in the refrigerator 🙂
