Cruising Yacht Keel Failure Research - Fixed, Drop and Canter Keel

Thank you for taking part in this research, the research is being undertaken by Kevin Gorringe at Plymouth University and the Maritime Learning Alliance College ( IMarEST), to identify the reasons for keel failure from an engineers perspective, approaches to surveys and failure to identify early stages of keel failure.

The problem: “ Since the mid-1980’s more than 75 boats have lost the keel with the loss of 28 lives.”Verisonal Law ( 2019 ), “‘We are currently involved in a number of cases where owners have discovered defective keels on their new or recently purchased used vessels, two such cases involve clients who had each purchased their vessels with the benefit of a full professional survey, and in both instances the surveyor failed to spot clear signs of early failures in the all-important internal keel support structure.”

Four identified primary reasons for keel failure:

1.       Failing to reach expected or required standards of engineering
2.       Substandard building practice
3.       Inadequate maintenance
4.       Coming into contact with an immovable object

It is important to have a cross-section of yachts types, construction and ages.

My thanks to the “Practical Boat Owners” magazine and “The Old Gaffers Association” for their support in this research. All information supplied is for research purposes only and will not be shared with any third party organisation outside of the University.

Question Title

* 1. Information about your yacht:

Question Title

* 2. Is the yacht sailed in heavy weather conditions regularly or has it been subject to grounding without a professional survey being completed? ( More than 1 answer if required)

Question Title

* 3. When the yacht was last surveyed were any keel issues identified ?

Question Title

* 4. Would you as the owner/skipper be able to identify the early signs of keel damage, give examples below?

Question Title

* 5. Have the keel bolts been tested ( if applicable ),  is the electric system of the boat bonded to the keel bolts. ( More than 1 answer)

Question Title

* 6. Are there any signs of water penetration between the keel and hull body. ( more than 1 answer )

Question Title

* 7. Has a professional marine engineer / surveyor undertaken any form of engineering or scientific testing in the past of the keel and fittings, such as ultrasound, x-ray, thermographic camera

Question Title

* 8. Has the yacht ever suffered a keel failure or serious keel incident at sea, please detail.

Question Title

* 9. Any relevant further information regarding keel issues, surveying etc.

Question Title

* 10. Thank you for your assistance, this research is to be used to improve  yacht safety and understanding of engineering issues. 

If you have had experience of keel failure it would help me if I could discuss this further with you, if you consent to me contacting you further to discuss this research information please complete the details below.
