I'm pretty certain that the red/orange boat on their website is ply, and this is certainly funny looking carbon: http://www.dynautic.com/Slideshow1.swfBut you're right: it seems that they are producing carbon/epoxy boats.

Posts: 3,348 | I have had no builder related problems with the Vectorworks system. However, I have two distinct operator problems! <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" /> Launching in surf; and kicking the lock open while sailing.
I think the Dynautics ruddersystem may be easier for ME to operate. If it isn't too costly, I will convert.
IMO, this is one of the nice things about our class, i.e. the freedom to customize according to personal sailing habits. If I understand correctly, SMOD doesn't permit this.

Posts: 61 Northwest-Germany Hamburg | Hi there, as Dynautic's first customer for the Blade i may add some comments here: The orange Blade is made of plywood, i had a test sail on it. Like many others who tried the Blade i was very impressed about the Cat and placed my order. First Dynautic intended to make the hulls in plywood carbon, for maximum stiffness and dent resistance. This was the main difference at that time to the other builder, Vectorworks. But as there was no experience with this composite structure, Phill the Blade designer convinced Dynautic to build the first hulls with foam core for reliability reasons. Now a high-density foam core is used, with pre preg carbon layers. Denting is also no issue, i saw someone hammering on the composite with no effect on the surface. For the rudders there are some options now. The orange plywood Blade had a AHPC rudder system, which pros and cons are well known. I decided for another one, made by a local supplier to me, shake design in Hamburg/Germany. Supports regional business, and spare parts mustn't shipped around halve the earth to me. On their website you can see an A-Cat rudder, similar to the F16 system which is now in design process. The head will be stronger with the tiller fixed to both sides of the rudderblade. The rudder will get a 20% larger surface compared to A-Cat and is then also used for F18ht. The stern at the Blade is higher with more volume compared to A-Cat or F18, so we chose the F18ht type that spinout problems shouldn't occur with this setup. see:http://www.catsailor.com/bb_files/94003-F18ht-1.pdf Now the moulds for the rudder are 3D-modelled and then CNC milled. At beginning of march my rudders will be available, hopefully together with the gray carbon Blade you can see on the Dynautic website. links: www.dynautic.comwww.shakedesign.de/rudder.htmHolger

I would use the Nacra rudder system, that is also used on the Eagle cats, this system is perfect (for me) not to say that other rudder systems are bad! | | | Re: Commercial Blades (Vectorworks & Dynautic)

It most definately did NOT have the AHPC rudders. Those would have worked, is that other type, Robi named the supplier in his post earlier. Looking forward to seeing you and your boat at Zandvoort Holger. Wouter

Posts: 61 Northwest-Germany Hamburg | Indeed i have to correct this, the rudders on the orange Blade were made by a former worker at AHPC who started for himself. But regardless who makes the rod system, i don't like it for myself. The system at my former Nacra500 worked always fine, but for a F16 it is a bit overdimensioned and heavy. Let's see how the new System behaves, i'll keep you informed... Holger

This could be informative, if you weren’t being so vague, perhaps you’d care to elaborate? <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

Well, we'll see both builds next to one another at the Zandvoort event in 5 months time so we can indeed directly compare the two.
Mirjam, are you coming ?
