Thursday last week was devoted to supervising the assembly of the fin onto the bulb which is now filled with a tonne of lead. The laser level came in handy for getting the vertical alignment right and in six hours the fin was welded to the base ready for final structural welding around the perimeter. It looks large and as my daughter says “serious metal.”
Bulb and fin of our Didi 40 Cr keel joined ready for final structural welding.
The upper and lower rudder bearings are glassed to the hull so I fitted the first half of the rudder to the stock on the hull today. The size of the rudder came up in two separate discussions over the weekend so after the fit today I was able to stand back and get a good idea of the size. It looks pretty big to me. What to you think?
After a successful trial fit and final adjustment of the top of the rudder to the hull shape I bonded the two halves to the stock with a lot of glue.

The rudder half clamped to the rudder stock of our Didi 40 Cr for final adjustment.
With the two halves of the rudder of our Didi 40 Cr glued together the total weight is too heavy for me to handle so the next time the rudder stock will go into the hull will be just prior to launch.
