I made the drawing back in January last year. It lacks dimensions, that's all.

I dare say you did, chuck.  But I can't find that drawing anywhere in my files!  Dimensions wouldn't go amiss ;-) if you could manage them. 

These might save a bit of time with the rudder leading edge:

Cheap enough for what they are but I have not used them myself.

Even the "nose only" section may not be big enough enough though.

Not sure I am terribly impressed with their asym section, and its hard to see that nose scaling to an 800 mm chord.

Then again David's asym foils would be dead easy to construct and those box sections look pretty strong to me.

Are the bilge boards going to be solid timber? That little design I have been looking at has the daggerboards and rudder blades fabricated out of plywood bent around internal formers and a center solid longitudinal. This seems a much more sensible way of making these rather than starting off with a solid block of timber and then planing a large proportion of the timber away as waste.

Way back, before I left NZ, I made a drawing of the bilgeboard like this. The outboard surface is 12mm flat plywood, and several longitudinals are glued onto it. Then two layers of 6mm plywood are bent over the longitudinals, and a solid radiused nose is glued on and shaped up. Yes, this is a better way of making them, reducing the weight to be hauled up and making the boards less likely to warp.

I think it's a different situation for the rudders. Annie has a pile of timber suitable for laminating them in three layers, and there's less shaping to do than for the bilgeboards.

In spite of the AGM, I've made more progress on the boat.  Fitting out is great fun.  I'm looking forward to putting on the deck, too, but confess to wishing I could farm out the rudders and bilgeboards.  I'm not worried about doing them particularly, but don't find this type of woodwork anywhere near as exciting as the accommodation!

I've decided to try using the new WA gizmo of attaching files, rather than my photo album for people to see where I'm at.  If nothing else, it's a lot quicker for me.
