juniordave, Looks good! There are two types of balance in laminates; actually balancing the number of layers/axis, and balancing the cloth itself. Worry about the latter when using lighter weight fiberglass. The ANSYS runs are interesting, but how much that will help vs...

Unbalanced layers is your number one reason, as 99% of carbon comes in a balanced fabric (unlike fiberglass, which you have to watch for!). Also, I'd put the 45-45 layers on the outside when you make the next set. Honestly I'd just do 1 layer of 45-45 on the outside, 3mm rohacell, then another...

As are Nacra with the Infusion, N17 and F16, at the least. These are all wet layup boats though, AFAIK, and SimonN's detailed comments above apply...Thai labor costs are low enough to make the shipping worthwhile.

Looking at the photos, I suspect you are thinking about the 3mm EVA decking material, standard on most all new F18's (well, C2, Infusion, Falcon). I have a roll ready to be applied. A full roll is about 6lbs. For an A you can probably get by with a lot less, a half a roll will probably work...

Thierry thank you for the design comments. In another class we've found the same thing the big volume isn't a problem in the light as long as you get the transom out. It's such an exciting time to be a cat sailor and watch all the latest designs!

Wow the Addiction looks huge! Massive volume in the hulls. Glad she isn't sticky when it's light!

Thanks for the clarification. We've gotten used to the car mounted cleat. Why the difference between the A and the 2-handed boats?

The Nacra Inter 20 was designed in 1998, launched in 1999 and the original boats all had fixed traveler cleats in the middle of the beam.

NED 27 thank you for responding with accurate pricing. I think it is good to disseminate this information, a lot of people are scared off from classes like the A's, Moths, 505's because they see a lot of carbon fiber and jump to the conclusion that it is too expensive for them. We have a sailor...

$27k is quite a lot. The Exploder is currently closer to $14.5 AUS or $13K USD. That is quite attractive; a new A-Cat for the priced of the good used F18's on the market! Even with the price bump they are saying come September, probably after they've paid for the tooling, a complete platform...

That's the kind of boat I'd LIKE to buy, as I think would most people, but even us OCD types find it HARD to buy a top quality product when it costs 25% more than the nearest competitor. Unfortunately this cost increase is inevitable to maintain that quality. Cost performance schedule. I think...

Best of luck the new boats looks good. Like the return to simple!

Foils are much more efficient at solving the lateral reistance problem. The hull adds some but this is only pronounced in super light air on designs that have a knife edge bow and the right rocker to use them when needed. Interesting development, I really wish the Paradox team the best of luck...

Has anyone looked at the data from the F16 stealth with T-foil blades? I'm wondering why they haven't been more prevalent in the A's before now and why more folks aren't using them in the F16 class? Are the tuning issues Simon discussed a hindrance to the average sailor who ends up getting worse...

Fun, thanks for the reports! Any chance you can snap some pictures of loading the J boards into the cases?
