Condition Survey and Valuation 2023

'I have just had a chance to have a detailed look through your survey report. I am delighted with the content, in particular all of the trouble-shooting pointers. This gives me plenty to work on and the reassurance that the boat has had a decent once-over by an experienced eye. The phone call before you finalised the report was particularly valuable.

In my line of work I'm expected to do a good job so I expect that of others and am therefore not usually lavish with praise unless it is well deserved. I found your service exceptional'.

Thank you for revisiting the boat today and for a staightforward and professional service in general. I have already recommended your services to the Westerly Owners Association.




Thank you very much for the survey. You did a great job and I would highly recommend to others. I will tranfer the funds this morning and have added a little extra so you can get yourself a few beers to say thank you!




I have just had Guy Simmons from GMS Marine Surveys complete a pre-purchase survey on a boat that i'm buying, the report was very thorough and the report that he sent was very detailed, he left no stone unturned. I would, without hesitation, recommend him very highly to anyone purchasing a boat, I do not think you will find anyone better. Very professional and very approachable.

R. Mackenzie



Really very thorough, great report and very knowledgable. He was even happy with me being present during the survey! 

The report had digital photos of the problem areas and a summary of what could be done to remediate. I received a digital copy and another colour printed copy in the post. 


To whom it may concern,

I recently acquired a Westerly Discus based in the Tide Mill Yacht Marina, Woodbridge.

As such I requested the services of Guy Simmons to conduct a full pre purchase survey of the vessel, both in and out of the water.

Mr Simmons was entirely professional throughout both visits to the vessel and presented me with a brief verbal assessment of his findings which was extremely helpful and was communicated in an informal but expert manner.

This was shortly followed by an extremely in depth and comprehensive 26 page report which was compiled in an easy to understand manner, which for a "non technical" person such as myself, was excellent.

Any manners requiring rectification were highlighted through the report, these and other matters were subsequently subject to an addendum at the conclusion of the report.

I consider that the cost of the report was extremely good value and I cannot speak too highly of the service provided.

Mr J.M.Ablitt



Hi Guy,

Just want to say many thanks for an excellent report.

I've transferred the £xxx across to your account so it should be there when you check online.

Once again an excellent job


Thank you very much. I surely think you are a very serious and will recommend your company to friends buying boats in UK.


Henrik, SWEDEN
