The randomness of the weather, children, Maths projects and life in general has slowed work on the boat.
I did manage to fit the Centreboard Case Cover, and the Centreboard Pin Covers. The Case Cover was easy. The Pin Covers not so.
It would have taken about 30 seconds to drill the pilot holes for the screws before the Centreboard case was installed in the boat. The Covers are very close to the hull, which is of course angled upwards.
Good luck getting a drill in there, or even a 90 degree adapter for your drill. In the end I used a 45 degree adaptor for a power screwdriver (much smaller) and a drill bit with a Hex Adapter built onto it, and I had to cut the drill bit short.
Then to get the screws in, I used a ratchet screwdriver with the 45 degree adapter. Using a power screwdriver risked making much of the screw head, and getting a messed up screw out from there was not going to be fun.
The first Pin Cover took about 2 hours ! It involved a lot of trial and error. Particularly the error part.
The second, about 20 minutes.
You can get ratchet offset screwdrivers and I see one of these going into my tool kit. Should there be any problem with the CB which required removing the cover, I'd be toast without one.
