F85SR Concept Boat

I see that F85SR stands for Super Racer.
The way I see it, if you omit the curved board option and keep the larger cabin, you could have a cruiser that would put most racing craft to shame.
Just something to ponder over a rum or two.

Anyone interested in turning this concept into reality should let Ian know.
It would be a fun project.

Folks,
I just couldn't resist the attraction of this

concept

craft. F-85SR

So I've bitten the bullet and started to build the (F-85SR) Farrier 8.5metre Super Racer.

I have found personally that armed with the right attitude building can be nearly as much fun as sailing.
Well not quite but it can be a lot of fun and good quality and highly detailed plans make it so much easier to enjoy the build.
You can't get better plans than the ones Ian Farrier draws up.

A photo album has been created on Catsailor to file away pics of the build for anyone who may be interested.
I hope to keep adding pics as I go along.

So far the float frames have been cut out and the float bulkheads have been made.

I hope to get the strong back down next week so I can start on the floats.

Fun times ahead.
Regards,
Phill

Farriers just became sexy! I want one too..

Rolf,
I always try to build good looking boats. From the plans that I have received the F85SR really is a great looking boat.

All I have to do is build it and......

Don't you need to finish your current project <img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" /> <img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" /> <img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />

And also needs to build a couple of smaller boats as pay for his daughters kitchen <img src="<>/laugh.gif" alt="laugh" title="laugh" height="15" width="15" /> <img src="<>/laugh.gif" alt="laugh" title="laugh" height="15" width="15" /> <img src="<>/laugh.gif" alt="laugh" title="laugh" height="15" width="15" />
Hi Phill, Can you email me my computer died(insert swear words in any lanuage here)
Thanks Richard

I have not been able to get near the F85SR for several months because of some pressing issues of more importance. I know that is hard to believe.
Anyway I have posted a couple more pics and now hope to start making some real progress. My next step is to make an oven 600mm x 1200mm x 2400mm. I don't really need it to build the boat but it would be handy to have when heating large quantities of resin, post curing smaller components and heating foam so it can be shaped to the batten mould. The F85 is a good excuse to build toys that I can use in later projects.

I quickly threw an oven together today with the help of a couple of friends who dropped around to see what I was up to.
This is not the

all singing all dancing

oven that I want to build to post cure and rapid cure of components but something that will heat both sides of foam up to 1200mm x 450mm so I can start planking the floats. The oven has 3 configurations that will deliver either 78degC, 103degC or 120degC. I put a couple of test pieces of foam through it today and while the foam can be bent at 78 it is easier and has a much better memory at 103 deg C and above. So I'll go with the 103 deg C config and this should help the planking go smoothly and quickly.

I started planking the float hull with foam today. Started late this arvo because it was a great day for bike riding , 1 metre planked and 7 to go. .
I went down to the local supermarket and bought 3 x 5kg bags of rice. I'm using the rice as weights instead of point loading the foam with clamps.
The foam goes into the oven, comes out and goes onto the mould and the bags of rice go on top to hold the foam into shape while the screws are screwed in from the back.
It cost me $37 for the 15kg of rice but it seems to work rather well and we can eat the rice when done so it really didn't cost anything.

I'm rebating the foam with a rebate 10mm wide in each sheet and 5mm deep. Cutting the rebate is taking a bit of extra time but this helps to ensure the level of the adjacent sheets is the same and will hopefully help reduce the fairing.

I'm assembling dry and leaving a 5 to 7mm slot and will force bog into the gap to form the seal that will be needed when I'm applying a vacuum for the glassing.
I will probably take some more pics tomorrow.

Phill how about a post with some pictures on the design of the oven?

Les,
The oven is very simple. I ordered some fan heater from an electronics store a couple years back,. The were offerring 2kw heater for $15 ea. I ordered 5 of them and they sent me 10.
Each heater has 3 heating elements and a fan all wired separately.
I'm using 2 elements in each heater and the fans.
The oven is simply a box made from 33mm mdf on the top of a steel frame. (Normally used as a table.) Ply sides and a 9mm MDF botton. The are two timber rails inside to slide the foam in on.
The hot air is blown along the lower surface of the foam and then turns around and runs across the upper surface before it can exit out a slot just blow the 33mm mdf table.
A baffel is made up to help the heaters grab the already preheated air- heat it some more and it is driven back in. When the heaters are operating with out the baffel and only two elements running you get 78 deg C.
Insert the baffel and you get a bit over 100deg C - around 103 to 106.
Switch in the third element and you go over 120 dg C.
I have added some pics of the heaters used and the oven itself with others to my photo albumn.

Thanks Phill

The Float half is laminated with foam and will probably get its inside laminated next Monday. I've added a pic of the float and the left over foam to my albumn.

Hi Phill, The link http://www.geocities.com/phillbrander takes me to what seem to be a

page. Do you have a current link to your album?

Thanks
les

Les,
That is a blast from the past.
I put that stuff up back in the late 90s. Yahoo made changes and most of it went into the ether.
I had to move the pics to flickr. I don't even know if they are still there.

The album I was referring to was my album on catsailor.

F85SR Building

I hope this helps.

PS- how does one become a member of the -

Royal Society for Making Cool Stuff

I laminated the inside of the float half today. Managed to pull 22.5 inches of mercury using the foam itself as one side of the vacuum membrane. I've added a couple pics. It did some maths and that is something like 53 tons of pressure over the surface on the hull. Nothing like a good vacuum.

It doesn't look like you used peel ply, bleeder, or breather.
Any reason why?
Did you put the sticky s*** on the outside?

Les,
The absorption fabric is black. Maybe that is misleading as the order of layers is foam screwed to the frame battens from the outside (screws miss penetrating through the foam by 3mm), bi-di glass(0/90), peel ply, perforated film to release the absorption fabric and then the black absorption fabric and then vacuum film.

I used slow hardener and given our temp at the time I would have had to run the vacuum pump for 15 hours so I covered the structure in black plastic , stuck a fan eater up one end and after 30 mins the temp of the structure stabilised at 40deg C. So with that temp I ran the vacuum for a little over 5 hours.
I have just started to strip the layers off and the laminate is looking great. After peeling all the layers off except the peel ply I took some pics and put them in my photo albumn.

Phill

Folks,
I've been off on a holiday up the coast with extended family. Bike riding, Kayaking and bush walking. Camped on the grass just above the beach. It's a damn hard life but someone has to do it- well I suppose I should get some more boat building done. I'll probably pull the first float half out of the mould on monday,if I can get around to it. I'll post some some more pics beforehand.
It's all fun and games.
Regards,
Phill

A couple more pics have been added to my F85SR building Albumn.
Below is just a pic of the bulkheads and stringer forward of the main beam.

The first float half is out of the mould. I'm very happy with how fair it has come out. Just the tougue of the rebates are pushed up a little but this will get fixed very quickly with a long board. Then I'll fill the rebate gaps and it will be ready to glass after it is joined to another float half.

I've put more pics in my albumn as per below:-

The first float half has been hoisted to the ceiling out of the way and yesterday I spent 2 hours cutting and cutting rebates in the foam for the next float half.

Today I planked the second float half in 4 hours. The oven we made makes it so easy. Each foam plank needs 5 mins in the oven and when it comes out you can make almost any shape out of it, but you have to be quick because it cools very quickly.
The time taken to make the oven was well worth it.
I was helped with my 3 x 5kg bags of rice. They hold the foam down really well while I screw the foam to the mould.
I will probably apply the inside laminate later in the week when I can get some friends together to help. It's not so much that I need help but extra hands really make a difference when chasing the smallest of details to get everything just right.

Hi Phill. I see the trimmer is still working, More butt than class,hopefully it'll last the whole process. Then it might be time to retire it??
Richard

Richard,
You missed out on a fun day today laminating the second float half. It must have taken us around 30 mins to find all the leaks when we turned the vacuum pump on but it was worth it. We managed to pull 25 inches of mercury,12 pounds of pressure on every square inch of the laminate.

I'll fit the bulkheads later in the week and then the lifting foil center cases that arrived a couple of days ago.

They forecast rain for the rest of the week so that should give me more time to work on the boat.

Regards,
Phill

Hi Phill,
I sent you a pm but as a new member perhaps it didn't go through. If you could send me some blade plans I'd like to send you some money.
Thanks.
pat

Hi Phill
A fun day laminating, Is probably better than a night shift. I'll catch up again when you are ready to join the two halves, Sing out when

Richard,
I don't think I've touched the Tri in the last two weeks. Too busy taking advantage of the good weather, after all that rain and renovating our kitchen. Hopefully the kitchen will be finished by the end of the week and I'll get stuck into the third float half. I'll give you a call when I'm about to join them together.

Regards,
Phill
