Thank you all for that information.

The blade seems to be a really nice design and if, for a similar cost, I can build a hi-tech cat, sure I will do. That's exactly the kind of boat I was looking for my test. Many large Cats are also builds from striped plank or ply design, so it will be very good for me to see if I can manage a good result with a small one before starting a big one. Anyway the big one is for a live aboard project in about 10 years from here, so I have some time to play on the water before.

I have already checked the WHARRAM designs for the large cat, but the Hitia 17 is not what I’m looking for right now. But you’re right, they’re designs for large cat are very interesting.

Anyone haves an idea of the price range it can cost me to build a blade 16 using plywood? I don’t need all hi-tech parts as I don’t plan to race with it.

Thanks again to all of you. I really appreciate.
