Simon Allan Marine Surveyor



Simon is a marine surveyor providing surveys on yachts and small craft for both first time buyers and experienced sailors alike. Covering mainly the South West of England and South Wales his work takes him all over the country helping Clients to better understand the condition of the boats they already own or are thinking of buying.

Before becoming a qualified marine surveyor with the International Institute of Marine Surveyors, he studied mechanical and production engineering at college and obtained a post graduate fellowship from Cranfield University gaining membership of:

  • International Institute of Marine Surveyors
  • Institute of Engineering and Technology
  • Fellowship in Manufacturing Management

Born and raised on the inland waterways - his father owned a steam narrow boat - Simon now focuses on sea going vessels. A keen sailor himself, he owns the wooden 50’ Laurent Giles ketch, September Moon that he recently sailed to the Baltic and back. He also owns a classic 1964 Aqua Craft ski boat that he restored himself.

Survey request dealt with promptly at the agreed price and resulted a in very comprehensive report, backed up with a picture library and explanations, plus recommendations for repairs and possible additions. First rate, professional and highly recommended.

Simon's helpful guidance in discussion before the survey, the immediate post survey phone call with a synopsis of the result and subsequent speedy issue of the final report made the buying decision easy with the confidence of Simon's undoubted knowledge and experience. Followed by the offer to refer back to Simon means that the survey fee was a real investment for the future ownership of my new boat.

Preparation for a Survey


Make sure we have the correct vessel details and location. Ensure the boatyard and broker or owner know when we are coming and we have access to both the yard and the vessel.

Health and safety

The vessel must be safe and accessible. We may not be able to go aboard if the vessel is unsafe or access to the site is unsafe.


Please ensure all the keys are available for the boat and for access to the yard or site.


Have sails available for inspection. Remove unnecessary equipment and personal effects. Please leave bilges clean and make sure we have access to all areas.

Masts, Booms and Standing Rigging

These can only be surveyed to head height if they are stepped. If they are un-stepped please make sure they can be easily found and identified in the boatyard.


Have all service records, warranty documents and invoices to confirm major repairs and renewal of major equipment available. Invoices for Standing Rigging and for Sail Drive Gaskets and Stern Drive Bearings and Bellows are very important. Try to locate the Invoices rather than Quotations.
Please have equipment manuals available. The broker’s inventory would also be of great assistance.


If they have been removed please have Make, Type and Serial no.


The vessel will need to be lifted out of the water and safely chocked on the hard. This needs to be arranged by the Client with the boatyard and broker or owner. Have the hull pressure washed to remove fouling growth. Please do not reapply antifouling until after the survey as we may need to remove small areas of antifouling to get moisture readings and to check condition of the gelcoat.

Moisture Readings for GRP Hulls

To get meaningful meter readings the vessel should ideally have been out the water for four or five days, depending upon the temperature and humidity.

FAQ - Frequently asked questions

  • Not sure how old my rigging is?

    Most insurance companies have policies that only cover the service life of items. Some of these are determined by the manufacturers guidelines and or by the insurers experience of claims.
    The same is true for standing rigging, even if it looks fine, there may be crevice corrosion unseen in the fittings and therefore most insurance companies deem the service life of standing rigging as 10 years or less if the vessel has been raced.

  • Age of Saildrive and stern leg seals?

    Most insurance companies only cover claims within the service life of items. The service life can be determined by the manufacturers guidelines or by the insurers policy.
    Most manufacturers specify the service life of seals and bellows for Saildrive units and stern leg however they do vary. For example Yanmar and Volvo are between 5 and 7 years whilst Bukh say they should be inspected and not replaced unless damaged or aged. Check with your insurance company and try to keep receipts of seal changes.

  • Do I need to be there for the survey?

    Nice as it is go over a boat with the owner or purchaser, it does distract the surveyor from a logical inspection process that can lead to a less than complete survey. Ideally, the surveyor is best left to get on with the job so that you get the most accurate and complete report possible. A the end of the survey the surveyor will call you to discuss his initial findings but you should wait for the written report which is his considered opinion on which you should base any decisions.

  • How much does it cost?

    Thee are standard rates for the different surveys available. These are competitive and reasonable so please call to discuss your vessel and the type of survey you require.
    There is no VAT charged or hidden costs. Travel costs are charged at 35p/mile if over 25 miles plus any marina contractor charges or bridge tolls.

  • How do I get the report?

    How do I get the report?
    The written report will be emailed to you normally within three days of the survey. You should wait making a decision on purchases until you have the written report, as that is the surveyors considered opinion.
