One illustrative case history of a Classic Cruising Yacht

Windrose is a 50 ft. Rhodes design classic cruising yacht constructed from single skin carvel planking over big oak frames. It comes to Robertson Boats for its maintenance and servicing along with any work the owners want done.

On a recent visit to the yard it was discovered some of the planks in the centre of the bilge had decayed and needed replacing. This was caused by water being trapped under some big bronze strapping that was running over the oak frames to help distribute the load. To fix the problem a section as long as possible was cut out of the affected planks to make it easier to bend the inch and 3/8 thick replacement planks back into place.

The new sections of planking were machined up and cut to length. Next the edges were slightly bevelled for the caulking process. With that done the planks were taken to the boat and installed. They were fastened to the oak frames with big bronze screws, and butt straps were fitted on the inside to reinforce the butt joins in the planking, then the new planking was faired up. Then the seams were caulked before being primed and puttied.

The internal surface of the repair was painted out with red lead and the external surface was primed with thinned down Primercon, two coats with a day to dry before the process was repeated until 6 coats had been built up. It was then faired up and antifouled. While the repair was being done, engineering work was also taking place with a new bronze heat exchanger built and installed.

The Teak coaming was stabilised to stop the movement in it. This required rebating out along the joints and inlaying a new piece of teak. The shakes in the coaming were also opened out a bit and splined with fine teak wedges, then cleaned off flush. The owner now stripped the coamings right back to clean fresh timber and varnishing them again. The boat was launched and run up to test the new heat exchanger. All was good – there were no leaks in the heat exchanger or the hull. The owners were happy and took the boat back to its mooring.
