The keel box, which has been a difficult nut to crack for the builders, is finally making progress:

The keel fin now passes through the box with a reasonably good fit. One corner of the box became too loose, but we will fix that by making the slider sheet on the fin 3mm thicker in that corner.

In case you wonder about the curved shape at the bottom of the box, this is the 25mm thick high strength plate that will take the main blow to the hull in case of running aground at speed.
