Hi
Thanks for you wishes.
The damage was caused by running the bottom of the keel into the sde of a concrete dinghy lanching ramp.
The keel was not quite down.
The shoe at the top of the keel "head butted" the box.
Not started on the repair yet due to other commitments.
Hope to start next weekend.
I am trying to keep a blog going as things progress.
