Folks,

I've just made up a prototype of my wing net rails.

The plans have the nets terminating on a 50mm round al section between the beams out near the float. Thinking this would not be that comfortable to sit on when sailing from the nets I had some M80 corcell foam machined into a wing shape. Then I made a glass tube with a 16mm intenal dia and 2mm wall thickness. Routed out the foam to take the tube. If I cut a slot the length of the tube I'd have a luff grove but I will cut slots 90 deg to this at intervals that I will work out once I get the netting.
My aim is to use an open weave netting that will be laced in place to avoid the need of stitching as the stitching is always the first thing to fail.
I wrapped the foam and glass tube in a layer of 200gm plain weave glass , 2 layers of 300gm Uni carbon running lengthways and another layer of 200gm glass and cured it under a vacuum.
This will give me a nice comfortable wing shape to sit on when sailing from the nets.
So far I've only made a 1200mm section to test out the concept and test for both strength and weight. This section seems very robust and only weighs 1.2kg per metre. I'll leave it a few days for the resin to get to full strength and then do some deflection tests. Even so I'm so happy with how it has turned out so I've just given the rest of the foam to Mark to get CNC cut so I can make up 2 wing net rails 3600mm long. I only need 3300mm and the off cuts will be used as supports between the wing net rail and the float.
I think I'll use the prototype as the bow foil.
There is a lot more work in this than getting a bit of al tube but I enjoy the work so it is just good fun.

Regards,
Phill

sounds great. One of these I days I am going to do some stuff like this, though I don't know if I have the attention to detail to get it all right

Ian Farrier will not be selling plans anymore after September 25 2012.
If you think that there is any chance that you may want to build a Farrier design in the near future you are better off buying the plans now while you still can.

I would think that if you change your mind there will probably be people out there that decide after the end date and desperate to source plans.

BTW:- I still love working on this project. I just vacuumed the laminate on the underside of all 4 beams. I'm very happy with how it worked out. I'm taking plenty of photos of all the work.
Damn shame Ian has decided to stop selling plans I think I'd like to build another one when this one is finished.

Cool down Phill,

if you want to build another one, Ian will sell you the plans for it. You are a good boat builder. With all your knowledge you have now and will learn during your built, you don't need the full support.

I think the real reason is that Ian is bored and frustrated by answering the same questions on the telephone over and over again.

And if not??? Ian Farrier is not the Messias of Boatdesign. There are other good Designers drwawing wonderful boats.

Hi Phill, do you have a larger break in your build or did you decide to stop just reporting here? I would like to read about the next steps of your project.

Best Regards, Michel

Michel,
I'm still working away. All 4 beams are ready for painting.
I've built nearly all aspects of the beams under a good vacuum of between 25 and 27 inches or mercury.

Building the beams is a very long process and doing it under vacuum has made the job much much longer than I expected.

This has also probably made more work in one beam than both floats. I'm happy that I've done it this way but would not recommend it just because of the amount of work involved.

Also I got side tracked organising and helping a group of 6 friends build some kayaks.

My next step is to paint the beams and floats including top coat prior to building the main hull. I figure that it will be easier to touch up the area where the beams and floats join than do the full paint job once they are joined. Just because they will be more difficult to move around once joined.

Phill

Just downloading a few pics, with a forecast of 42 deg C, its too hot to do much else.

IN the first pic I applied the glue with a caulking gun. Just went to hardware store and bought a water solluble gap filler cartridge for $1.98. Squeezed the gap filler out and washed it out. Put glue in, insert cartridge in gun and away you go.It is also a great way of applying bog for fillets and was a great help when joining the float halves together.




Clamping the tops on with flat sections of wood rather than screwing gave me a very fair top on the beams. Only downside is it took 40 clamps to do it.

A couple more

Finally some paint. Well hi build primer.

Mark Hasting has done an excellent job of machining a plug to make a mould for my F85 rudder.
Hand shaping doesn't hold a candle to the accuracy of his CNC machine.
I'm in the process of putting a finish on the plug.
After spraying with two pack the foil section has been cut back.
Once I've done the same to the back board I'll start waxing it to make sure we get a good release.
