Centre Board Question

[westsail1]

I’m renovating 1914 “Maisy” and have the C/B out at present. When I removed it I noticed that, with the handle tight on the deck, there was about 2″ of the tip of the board still below the slot opening. Is this “Normal”. If so is there a reason (e.g. downwind tracking etc) for this. Is there a limit to the projection below the hull in the rules? Is it a “good Idea”? I have no idea as I am new to the class. The Board seems to be a good quality laminated “Milanes” type but has had some rather “splodgy” carbon fibre cheeks added to the handle. This is either a repair or an attempt to tighten up the clearance in the case. There seems to be little damage to the edges and foot so I think it is “As built”.

Also:

The sheet track has been rather amateurishly formed in a series of bends and has a metal repair at the centre point which spoils the appearance and acts as a “Detent” to the carriage at the centre position. Where can I get a replacement track from please?

Hi,

As far as I know, in the rules it says that the c/b should not protrude beyond the keelband when retracted. I think I am reading this correctly but the rules gurus can probably confirm this.

Bill is correct.
The board must not protrude below the keelband when fully raised.
You seem to have other problems though as carbon is not allowed to be used in OK foils.

If you are competent with tools you could cut the bottom edge off the handle to get extra rotation and grind off the carbon (use a mask please).

Good luck

Thanks Guys
I was rather afraid that might be the answer. I’m wondering if the issue is just to do with the way the slot for the pivot bolt is fashioned and I need to replace a missing packer piece. Anyway I’ll get the tape out and check it all over now. The stuff on the sides is black and has some sort of cloth content so I suspect it is Carbon fibre. It looks like a bit of warmth and a decorators knife should remove it again. It looks nasty anyway so I’m glad of the excuse to lose it. Am I allowed to build up in some other material e.g. laminate some timber veneers onto the area above the controlled line?

Any thoughts on where I might lay hands on a replacement track while at it?

I think the c/b must be 20mm thickness or less all over, unless it is metal in which it must not be more than 6mm. The rudder just has to be 20mm below the waterline. You can use wood or glass on the c/b. The rules are fairly clear and you can download what you want easily enough.

I think this is right, but please check it.

Hi, are you sure the board is not pivoting on a slot in the centreboard rather than a hole, my board is doing the same. Will the board come up further if you pull it across the deck toward the mast? mine does. Anyone know the proper way of fixing the centre board in? Mine is slotted with shock cord holding it tight, surely this is not correct? R.

The centreboard should pivot on the bolt and the clearance between the bolt and the hole is controlled. You used to have to have a packing piece in the slot to make up the hole but, as far as I know, now you can just have a screw across the slot as long as the board can not move on the bolt more than is allowed. Does this help? It sounds like you have got a screw missing (in the c/b of course).

Hi Bill, You could be right about the screw missing, dont all sailors? ha ha. Thanks that clears up the mystery of my centre board slot and why the board hangs down slightly sometimes. R.
