Are PBO fibres allowed in the lay up of the hull?.I see kevlar is and carbon is not. Is this right?

I see in the rules it allows Glass ,is the only fabric not allowed in the hull carbon fabric? but carbon  allowed in the bulkheads etc.

No exotics in the hull shell..including centreboard case and transom - apart from that it is open.

Some may argue that wood is now exotic, but let's not go there just yet...

GGGGGGGGG

So is only bog standard glass allowed in the hull?

Did you see the reinforcing fibre in the Sunday Papers? It's already in Cars its Cannabis Fibre!
Where does the MR class sit on this?
When it says glass does it include the high volume stuff that caused much trouble in the Solings/Stars/Dragons and Etchells a fwew years back?

Usually its not the glass that breaks down ,its the crap resin used!Sell by date etc.

..bog standard glass....

The high volume stuff "Speretex" is not less strong or less reliable indeed the reverse and holds the resin better but it is also MUCH stiffer and that caused the problem, the few boats that were built using it before it was noticed are still at a premium, does the MR Class regard this as Bog Standard Glass? The ISAF does not but there are many advantages to not being an ISAF class!

How come Speretex caused the problem if it is stiffer ? Would I be right in saying that Speretex was the problem because it was not consolidated properly (ie) not vacuum bagged ! Never had any problems with carbon,and that suppose to be very exotic . So I suppose the simpler the cloth the more problems you have .Paper mache Merlin ,now theres a thought. Is PBO allowed? Would it be classed as Exotic in the class?

Because it put the existing boats - we are taking one-design here! - out of contention in the stiffness stakes.

As I recall the problem with the semtex as it was sometimes referred to in heated discussion was the way it was being used.

A certain well known east cost keel boat builder may possibly have been putting less matter into the ends of the boats.  Naughty naughty.  As a result the Dragons now have the swing test (bunch of arse) and a couple sail around with a load of lead in the ends.

There was no problem with the material, just the fact that the way it was used contravened the very sensible rules they had at the time and still have.  Nothing to do with ISAF just a cheating boat builders

MR Chairman 
Bog Standard meaning only the white stuff!

I'd like a glass boat, I could see the fishes then

HUH 
Boatbuilders,Want anything built ,build it yourself.

When you capsize you can still see whos doing what and what is doing who

If you have a boat reinforced with cannibis straw is this what they refer to as grass fibre?

Grass Fibre!
Boom Boom Mr Derrick!
As to cheating boatyards I doubt the yard in question needed to cheat and I know they checked everything through thier measurer who ok'd it but then with the benefit of hindsight said measurer has made quite a few rickets in the past. So an uncalled for slight on a double Olympic Gold Medalist and winner of over 100 major titles.
As to swing tests they are fun to do.
The cheating boat builder was German from Bavaria.

PBO YES OR NO

Whats the best way to appeal againsta parking ticket?

Pay up!

BAILIFFS, THEN NUT THEM.

Apologies  
BAILIFFS NUT THEM ,IF THAT DOESNT WORK ,OFFER CANABIS STRAW.

CANABIS FIBRE

I would refer the honourable gentleman to rule 4(n)i and he can make up his own mind.

If he is building a boat and is proposing to use any particular material that may or may not fit the descriptions in the rule, adjudication prior to construction is advised...

GGGGGGGGGG

I assume that the origional poster (Presumably Mr Connor of racing finish?) has a large stock of Practical Boat Owner magazines he needs to dispose of.

I'm not sure whether papier mache is considered an exotic fibre or not but i think Practical Boat Owner fibres may not be stiff enough to withstand the pressures of a full championship course.

My class and I would very interested to hear how effective vacuum bagging papier mache is, especially in containing the water/glue mixture and preventing it going all over the kids.

Beano, Dandy , Bunty ,sorry no yachty mags.

PBO probably won't work in a layup anyway as it doesn't take resin very well.

Ah ha, was wondering where the old GCRF had gone....

Dear Primary School teacher, 
Seriously if you are going to vacumn bag papier mache and it's easy with a suck end of a vacumn cleaner DO use a chemical glue that will set without air! The FT is good so is the Telegraph stay clear of the Murdoch Press! I used Cascamite and the compass housing is still in use moved from yot to yot after 16 years.

Mr HH 
Have you laid up and had experience with PBO?

Mr Stilloncourse ,your way off course with GCRF.

Well I reckon you've posted as "Balanced View" too.

Nope he's not Balanced View!!  I am he!!! Time to come out of the closet and like I said I wasn't having a pop at anyone at all - just trying to be humourous (even in the posting name) and from a FEW of the postings subsequently I did get a response but some people may be a little sensitive and for that I apologise.

Dont Apologise. 
I had feed back saying that PBO is difficult to wet out and for the  positive feedback I thank you.

Well SpliffySkiffy me old fruitcake, I reckon that leaves the disctinct possibility, although unlikely, that you're the patriarch of a certain 2 merlin family.

WHAAAAA

Now im confused. $6%&*"!(= oh yeh was where I, to much resin !Now did I mix the catalyst in @£$%

Still on course? - 2 Merlin Family doesn't narrow it down much. I think about 50% of Merlin families have at least 2 if not more.

yes I have used resin with PBO on standing rigging coverings on yachts, its okay for that job but laying up a boat I think it wouldn't wet out enough. If your looking for material that looks good maybe look at some anodised E Glass.

USED 
ANODISED E glass to heavy. Still holographic carbon looks good but im not going there.I have some PBO coming from Japan ,ill let you know about wetting out.

Best to save it for your rigging, let me know how you get on, have you got PBO weave or a spool of line?

Yes ,and we have got it coming in cloth format.

Drats Ive been rumbled

Ha ha!!!!  So Mr Primary School Teacher got it in one....  Now should we rumble him too???

No He or she will do it themselves .

AS WILL STILL ON COURSE .

AS WILL FLOPPY TOPPY

Try the caps lock button

what will I do myself???????

DONT WANT TO TRY THE CAPS LOCK BUTTON

so how many of you are talking to yourselves now?

Well if they are at least they'll understand the question and agree with the answer which may cut this short - on the other hand! Got to go race.

This fibre your all talking about, can you put milk on it and haveit for breakfast.

Personally I can't think of a better use for PBO than to pour resin all over it, jaming it's pages firmly shut!
 It must hold the world record for showing ditch crawlers how to pick up or leave there moorings month after month, year after year!!!!!!!!

Whats a ditch crawler on the water ? Inlighten

Canal boat mate!

Keep taking the pills Barry
G

It's not the pills that are the problem it's the "liquid" I'm taking them with!!!!!!!!!!!!!!1
