After the last sail and putting onto the trailer, the centre board plate on my MkIII would not retract fully. The raising blocks go cheek to cheek at the Samson post, yet the board is not right up. It is as if the lift wire has mysteriously stretched by approx 30mm. I cannot see any obvious damage. I have not hit anything that I can recall. I think I can effect a fix by simply shortening the wire, but would like to understand why. I raised and lowered the board in the water today, and apart from not retracting fully, it seemed Ok.
Has anybody experienced anything similar? Would a broken front swing bolt cause this?
The pivot bolt on my 24 is a huge stainless steel device which I couldnt see breaking. If it did break then when you lowered the board, the whole thing would fall out and be suspended by the wire. I have had my board out so I doubt there is any problem with the bolt, however the hole in the plate is not bushed so maybe there is some wear there or some elongation in the casing. good luck, look for the simple things first!
