These posts are all about my daily experiences as I meet clients, boatyard staff and during the surveys themselves. When I find the boat especially interesting or unusual, I like to write a little about the history of the boat. Please feel free to give any comments that you might have.

The Correct Anode Material for your Yacht

I'm not going to go into depth about the correct size, distribution and correct anode material for your yacht. The correct choice will depend on the hull material, salinity of water, berth location and quantity of submerged metallic equipment. There's already plenty of information out there and I would recommend the website of MGDuff for…

Flooded Yacht: Damage Survey

I was recently asked to undertake a Damage Survey of a flooded yacht. My instruction from the Insurance Company was to inspect and assess the nature, extent and cause of the damage to the vessel.

Water had entered the vessel over a period of time, leaving the boat low in the water and the engine partially submerged.

Mud accumulation around rudder bearing assembly

She was inspected out of the water at East Cowes, Isle of Wight. In my search for the cause of the leak and working my way from bow to stern, I found water and muddy residue around the upper bearing & seal of the rudder assembly. This provided good evidence that water had leaked into the vessel from the top of the bearing assembly. At this stage of the inspection, I could have packed up, gone back to my office and simply reported that the rudder bearing & seal assembly was the most likely origin of the leak. This conclusion would have been unsatisfactory as it would have required the re-floating of the vessel in order to test & confirm that the rudder bearing & seal assembly was leaking. This task would have involved significant additional costs, which would have to be borne by the Insurance Company or the Insured.

Flooding from around rudder bearing assembly of sailing yacht

In order to confirm that water had leaked around the seal of the rudder bearing, I built a dam around the bearing assembly, which was then fed with water from a hose. I then went outside to check for water. The YouTube video shows the test.

The result of this test confirmed that the faulty or worn water seal of the rudder bearing was the proximate cause of the water ingress. The head of pressure on the bearing seal from this water test was approximately 2 to 5 cm, which was considered to be very low. The rate of water leaking was estimated to be at least 3 to 4 drops per second. When the vessel was originally afloat, the pressure head would have been approximately 20 cm, which would have created a flooding rate that would have been approximately 4 to 10 times greater than the leakage rate seen during this test, although this rate would have been reduced due to the accumulation of mud inside the rudder bearing & seal assembly.

Survey of a Westerly Fulmar

The pre-purchase survey of this 1987 Westerly Fulmar 32 recently took place in Gosport, Hampshire, with the vessel ashore for the majority of the survey. The boat yard wouldn’t allow me to run the engine whilst the boat was in her cradle, so once the boat had been lifted into the water, I returned on…
