Marine Surveys

Having worked as a surveyor for over 14 years I have looked at probably every type of vessel and probably all construction types and materials.

Survey Process

I find out as much of the vessel and vessel history as available. This is always helpful although not all information is taken for granted and is checked during the inspection.

For an average 30-40ft sailing vessel I would expect the inspection to take anything between 5-7 hours.  Using a comprehensive check list the inspection starts at the external hull and fittings and moves logically up and through the boat. As well as making comprehensive notes it is usual to take over 100 photos as both a record and an aide memoir.


The report will be a record of everything I inspected. A report is usually from 10 – 15 pages. Where there are issues or items that need attention a See Recommendation is written at the bottom of the relevant paragraph and a list of recommendations is provided at the end of the report. These are rated in order of priority.

Costs are based on several factors depending on the type of survey required.

These are principally based on vessel length but are finalised after discussion with the client. Travel outside a ten mile radius is added based on mileage. Any additional costs are agreed before the survey.

For unusual or very large vessels such as houseboats it has proved more reasonable to charge an hourly rate rather than by vessel length.

Terms and Conditions of Business

As part of my PI insurance I am required to provide my Terms and Conditions.

These come with a request for survey form.

Vessel Preparation Cost

1. The client will be responsible for any costs incurred in preparing the vessel for survey or inspection, including any boat movements, removal of boat from the water, securing ashore and any other boatyard or marina costs including the repainting of sample areas of removed antifouling or other coatings.

2. The client will be responsible for all costs incurred of removal and reinstatement of fittings and fixtures including linings, claddings, the removal and replacement of secured sole boards and the opening of sheathing or other coverings at the discretion of the surveyor. The surveyor will not undertake the dismantling of any part of the vessel and will only remove portable items. No removal of other items as outlined above will be carried out without the prior consent of the owner or the owner's agent.


3. The client will reimburse the surveyor for any expenses reasonably incurred in the execution of her services. The surveyor will where practicable, advise the client before undertaking any work as to the approximate total of expected expenses.

4. Surveys undertaken within a ten (10) mile radius of the Bursledon office (excluding the Isle of Wight) will not incur travelling expenses.

5. Expenses will be paid upon receipt of the report of the survey for which they were incurred unless otherwise agreed

The Report

6. All reports of surveys and other services issued by the surveyor will be an impartial statement of all findings and will be subject to the limitations and conditions stated therein. Opinions will be given in good faith and without prejudice.

7. Reports of surveys will only be valid for the time at which they were undertaken.

8. No guarantee of is given or implied against any latent defects or any design faults, or the suitability of the vessel for any particular purpose or for the general safety of any vessel.

Surveyor's responsibility to client

9. The surveyor's responsibility is to the client commissioning the survey, inspection or service and to no other party, unless specified to the contrary in writing.

10. All reports, photographic records and other records of surveys or other work carried out by myself will be treated as confidential unless otherwise agreed in writing.


11. Fees for the standard range of surveys are based on the size of the vessel.

13. The fee or balance of the fee is payable prior to the receipt of the report.

14. Interest will be charged on accounts outstanding over 30 days at 8% plus the current reference rate plus any administration costs. Delay in payment may result in the delay of written reports.
