Ed,
Its a bit early for me to know for sure but I do
expect if built with care 900kg would be achievable.
I expect my floats beamed and painted will be well under 100kg each and that leaves over 700kg for main hull rig and sailing gear.


I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!

Phill-

I would be interested on how your numbers compare to my F25c...

See info from Bill Adams Jr who built all 48 F25c below:

"Thom,

If I remember right the main deck and hull were about 600#, the beams with hardware were about 100# each and the ama's were about 150# each. For a total of about 1300#. I remember that 2 guys could lift the hull and carry it around the shop before it had bulkheads etc!(The main deck was heavier than the hull). All of these weights were before paint and hardware and all the other add-ons.

The way we flipped them was to remove the ama's and then support the bow using the spinnaker pole in a cradle that allows it to turn. Support the pole close to the bow, not at the tip. Then pick up the back of the boat with as many friends as you can find and roll it over. We used to do it all the time with 6 guys. When it is upside down support it under the beam pads front and back. (Don't let it hang on the pole for a long time)

Thom,
I have been taking weights but not lately and currently held up working on it by a broken collar bone so I can't do much with the boat except give you estimates from what I've measured so far. Bear in mind that I'm building using the heavier glass laminate option and carbon beams built under vacuum.

The floats were around 130 each with the lifting foil cases installed but still some internals and fairing which has already been done but not weighed since. I expect it to be less than the 150. and the floats are much more bouyant , ie- larger, than the F82.

The beams and hardware should come out quite a bit lighter. Maybe as low as half. The folding mech only weighs around 5kg 11pounds plus bolts per beam.
I don't know about the main hull as I have not started it yet.

I will be able to provide more info when I am a little more mobile and can do some more work.

Regards,
Phill

Sorry to hear about your injury.

I wanted to ask you if you had seen Tor Rabe's mast for his F22R? Its a custom shape and similar to some CST shapes.

Take care of yourself,

I have been following this thread for a while now and finally took the plunge yesterday to get a F-85SR built. I wish I had the time and patience to build one of these trimarans myself, but I don't.

Instead, I have commissioned Michael Mallory of Multihullsdirect in the Philippines to build the boat. I have been assigned Sail No. 10 and I hope to launch the boat around the 1st October this year.

I have decided to get a standard F-85 built, with following modifications:
- centreboard option (so that it will kick back if I hit a rock)
- reinforcement for the lifting foil cases, so that I can fit them in the future
- all the necessary attachments so that I can race in Category 3 passage races.
- It is an epoxy foam boat with carbon reinforcement only as specified in the plans

Initially I will be racing in the Philippines, but will probably take it back to Perth once my current assignment is over, maybe in 2015.

I am very excited to see how this trimaran performs and will keep you updated with photos. According to Michael, by the end of April, the hull should be well and truly taking shape.

Michael is looking for more customers, so if you want his contact details, please PM me. I think it is a pretty competitive build price, compared to what second Farriers are currently priced at in Australia.

Have just received the first F-85SR main hull photo, which is hopefully attached?

Edit - Seems it is attached, but how do I make it display in the message itself?

BTW:- this is not my boat however this F85SR builder only lives a few kms from me.
Always handy to have someone to compare notes. Especially when it is someone who has built a Farrier Tri before.

Phill

Hello Ian-

I am always amazed to see these photos from builders around the globe.. The surfaces appear to have come from a mold.

Have you heard from Fiat about his F32SRX?

How is the new factory coming along? When do you think the manufacturing of the F22s will start??

I managed to put my folding mechanism together and pinned it up on the back wall for storage.
Mark Hastings machined the mechanism for me on his CNC and then offered to put a 10mm drill
through the centre of the pins so I could use a tool to remove them easily should I ever need to once
the boat is finished. Interestingly that hole through the pins reduced the weight of all the pins by 1kg.

Small savings add up.

I have just finished the internal laminate of all 4 beams.
My broken collar bone really slowed me down for around 3 months but that is finally coming good so it is all ahead full again.

On the last beam ,which was a front beam, I took some notes.
I noted the quantity of resin in each mix, the time of the mix and the temp in the workshop at the time of the mix.

The reason I noted down the temp & time was because the day was supposed to get quite hot but at the time I started it was quite cool. I just wanted to make sure that I stayed inside the vacuum window prescribed for the resin I was using.

I found that the combined weight of glass and uni carbon was 1.17kg. All up I mixed 1.45kg of resin. 80gms of this was used to mix up a bog for fillets along the beam side/bottom join, leaving 1.37kg of resin to wet out the 1.17kg of laminate.
Following wetting out the laminate I pulled a good vacuum of 25 inches. Upon cure I weighed the peel ply and absorption fabric as it was removed to work out how much resin came out in the fabrics. I found that around 200 gms of resin came out leaving 1.17kg of resin in the laminate.
I was very happy with these results.

I must say it is a relief to get this work done, it is fiddly working inside the beams because of the flanges.
Since then most of the internal beam B/Hs have been fitted so after a bit of work to install the UFS recess and some reinforcing around the inner beam end I will be able to start laminating the outside of the beams which should be much easier work.

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.

Regards,
Phill

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.

Best Regards, Michel

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.

Regards,
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.

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.
