I managed to get up the mast this morning. Kudu was brought alongside the high harbour wall yesterday, and when the water had ebbed, I borrowed a ladder which I attached to both the topping lift and main halyard, then created as make shift bridge up to the masthead from the shore.
Once upon a time I wouldn’t have thought twice about it, but I haven’t been climbing for years so the height got to me a little. Well, not quite the height, more the moving ladder.

Once I got up there I assesed the damage.  The antenna bracket is broken, and the masthead light is in tatters. I think I might be able to to fix it, but one of the (not cheap, LED) bulbs was broken, so I decided to just snip the cables and remove it. I still have nav lights, although I might be breaking the colregs very slightly by having the steaming light on… I guess I’ll just sail with the engine on tickover :p
It’s a bit annoying that it’s broken since I’ve only just fitted it all. Nevermind, these things happen… especially when Bridlington harbour put a flippin long keel boat next to you.
