Replacing little plastic flaps at top of rudder
      #1861916 - 17/05/2008 07:49

This is Witchfinder's annual weekend out of the water.

Attached to the hull on either side of the top of the rudder are two plastic flaps. They are pretty flimsy and I suspect are there either to shape the flow over the where the rudder post enters the hull or to stop free floating bits of weed getting caught in there.

Well, they both now have tears in them. How to I replace them? I can't recall ever seeing such things in chandlers. Would the material that poly bottles are made of be adequate?

Perhaps there is a picture of your boat there already.

We initially replaced ours with Mylar centre board gasket strip as found in dinghy chandlers. Use impact adhesive.

I'm not sure how effective they were, and eventually we abandoned them with no obvious effect on performance.

Try a dinghy chandlery.... they are often made from Mylar, and are common on dinghies to seal the centre board slot....

[Darn... beaten to it!]

Thanks to you both. Saves me the embarrassment of going into Foxes and waving my arms and talking about little plasic flaps. "Dingy center board slot" and "mylar" will make me sound much more like I know what I am talking about. A trick I seldom accomplish.

A pleasure. Actually many dinghies these days use sailcloth for centreboard gaskets, as Mylar can be too stiff for the job. Don't let them sell you that, its Mylar you need.

Are you talking about this?


Missing from my Moody. It is just to stop bits getting in there. I made a new one out of some hard plastic but I was told the original (still there on the other side but well painted) was made of tufnol.

Yes, just like that only a bit longer. I now have some mylar "Slot Strip" and will fit it this afternoon. Leaving it off is not an option as the Admiral has ordered me to replace it.

Wish I'd asked this question a few weeks ago.
I just used some stiff thin plastic (cut from a box) on my Sigma 362. Apart from how long it would last I was concerned about antifoul adhesion so roughed up the surface with some sandpaper.

If it doesn't prove durable at least I now know what to ask for.

I was not planning to anti-foul the mylar on the grounds that it would be a clever foul-thing that could stick to the mirror non-stick finish. We shall see...
