It's a high end 2 part poly that has UV inhibitors in it. I don't use it (I prefer to paint my carbon white), but I know it is used in many different applications, especially for carbon pieces. It is used in both marine and auto industries.

Spray or brush a quality clear coat into the mold first, such as Awlgrip. It can also be sprayed afterwards, but spraying the mold will yield better results.

Way to go! My quote is slightly different (smile): I think ISAF updated the case book for 2005-2008, and case 81 now notes only that 18.2(c) ceases to apply to the boat that tacked, rather than the whole of 18 ceases to apply. This makes quite a difference! Yes, It does. I'd expect that since they ...

Ok, all. I've done a bit of homework, and I have it here straight from ISAF, Case 81. Quote in full: "When two boats on the same tack are about to round a mark, rule 18 applies even if the boats are on a beat. When one boat enters the two-length zone clear ahead of another boat on the same tack, rul...

Either way - as diagrammed, I would still rule in favour of Blue if I was unfortunate enough to have to sit in that particular protest hearing. :lol: Marko I would disagree. I have always favored Green in this situation, although I think my rule number has changed. Initially as stated, I thought Bl...

Hi, Marko. I'm having difficulty going with Lester on this one as well, but I am beginning to understand why it may be intended to work this way. Allowing the clear ahead boat to tack within the zone causes unnecessary chaos. Usually, if clear ahead wants to tack in this situation, it is to protect ...

Re-kindling an old topic that is sure to be looked at in our upcoming rules evaluation; F6.2(b) allows for the use of a topping lift restraint line . F6.3(a) allows for terminations that pertain directly to the running rigging . As an example, the termination for a headsail tack control line is not ...

For years I thought I had the meaning of 18 completely understood. Now, Lester has to come in and wreck everything. How on earth am I to get any work done (at work) when my life has been turned upside down because I have to learn rule 18 all over again..... sigh...... :( :) :shock: :? I'm sticking w...

Lester, I see where you are going with this, and it has a certain amount of merit. Most importantly, is that I think we both agree that Blue is wrong, at least at the point of contact. To stir things up a bit put Blue tacking to starboard at least 1 boatlength further to leeward, so she can establis...

Isn't it just 18.2(c) which is turned off, not the whole of 18? 18.2 Giving Room; Keeping Clear (c) NOT OVERLAPPED AT THE ZONE If a boat was clear ahead [...]. If the boat that was clear ahead passes head to wind, rule 18.2(c) no longer applies and remains inapplicable. Yes, that is true, but since...

Why doesn't 18 apply?

18 is turned off as soon as blue crosses head to wind (18.2c).

Rule 15 was broken.

I have always found it difficult to "predict" how much the lighter jib booms will bend while under way, making it difficult to get correct jib twist. With a boom that flexes, you're either too flat in the light stuff, or are carrying too much twist in the puff. I find the same truth with my mast. I ...

Anders, are you using S glass or E glass?

Hi Lester Unfortunately it seems that is not allowed in Germany, despite I thought Iomica and Isaf rules were valable for every Country. Interesting that an NCA would allow a willing skipper and an unused boat to sit sidelines while the rest of the fleet sails on. I guess your NCA feels confident t...

Hi, Anders. I'm experienced, but would not consider myself an expert. I have been lightly trained in aerospace composites , so I have a bit more knowledge than the average home builder. From what I have learned, your molds generally must be able to withstand your post curing temp. Yes, it is highly ...

I have a tex. deck. It has developed a lot of pin holes and leaks quite badly. For this reason alone I am not in favour of them. I suspect a standard deck would not have developed the leaks. I am also a firm believer in afforability for the class. I'm sorry to hear your deck is leaking. The reason ...

You will find your answers in the ERS. I thought there was a link at our homepage, but I was unable to find it quickly. Here is the link to the ISAF ERS page. The IOM class is using ERS 2001-2004. http://www.sailing.org/default.asp?MenuID=t87gGWxs/B7wq`QsLGLVxyzMZsaHJMUHYHl2QWODqDliRvIJKrzDDI6Xz1U-c...

One important thing that I would like to hear more about are the structural benefits (if any) of texalium. I have heard annecdotal evidence that this material is stronger than standard fiberglass. I have also head stories that the coating does nothing other than change the appearance of the fibergl...

I am just returning to R/C racing after many years These are two very different issues. Hello, John. We hope to see you in the IOM class soon. You are correct, there are 2 different issues on Texalium being discussed around the forums. However, if Texalium is allowed within the rules as a permitted...

How 'bout:
"Materials added to GRP that have the sole purpose of cosmetics, and are easily identified as such shall be allowed."
This may be a situation that the material in question be submitted and approved on a case by case basis.

The Texalium deadline is approaching. Soon, if not already, it will be discussed within the TC. This time 'round, I think the owners should be involved. It is after all, a class controlled by it's owners, correct?
What do you all think? Use it, or lose it?

Beautiful work, it makes me want to build a wooden boat.
keep us posted on your progress!

Bye to all

The only pictures I've seen of one close up are already posted here. What information are you specifically looking for?

I also have one as an old project. I am building a standard type foredeck for it, with a bulkhead just forward of the mast. The original foredeck is currently removed. It will have an arm winch just forward of the mast trunk (keel stepped).

Hi Steve, Just as a clarification (not sure if I understood correctly). It is clear the twin rudders are not class legal but you mentioned "Wings" are? Does this specifically mean a hydrofoil type of wing? Or at least a wing at the end of the rudder that will help lift the transom of the boat? or f...

Ok, that's fine, as is also what I expected.
It just seemed strange that the class is practically begging for volunteers, and you have a person that is willing to take the job, and the vote was nearly 50/50.

I don't suppose it would be as simple as giving the position to the candidate that lost?
