Posts: 69 | I agree that this boat is bad butt. All of the details look so nicely executed. I think a few are coming to the US this summer as are new eXploders. As I understand it, both manufacturers now use CFD for analysis and design. Incredible to see that level of refinement for a small catamaran. Foiling is really powerful even in the lake environment. At Lake Lanier in lighter air if I or others can get on the foils, the distance to other boats increases dramatically. At the very best case for foilers in just foiling conditions, they can sail about the same angle as a boat that is going mild downwind but be foiling. It's a good thing we have gone to breaking out classic and foiling boats in scores for this reason. The downside seems to be that as the boats get more optimized for foiling, they are suffering on mild downwind performance. I haven't seen any deck sweeper that will go as well as a regular sail and boom configuration in light air downwind. When I bought a DNA before in 2012, it was 15.5K Euros for the platform, so this one has gone up about 5K Euros and a ton of advancement in style and design and performance. PS - check out the sealed trampoline Bach made for me on the eXploder. I think he has gotten quite a few orders and has started putting a lighter pentex material underneath to reduce weight a couple of months ago just like the newly released DNA. Way to go Carolina Sails in Greenville, SC. I noticed the boat felt quicker upwind even when sailing with a traditional rig and not the deck sweeper Bach built for me that I use now. I also seem to be getting better gas mileage when towing and noticed the trailer getting a little skittish at 80. It's cool that both the DNA and eXploders from the last several years are already built with a wing shape in the underside of the trampoline.

Posts: 12,310 South Carolina | I really wish you guys would come up with another moniker than "classic". average classic clichéd conventional exemplary hackneyed model most characteristic paradigmatic prime quintessential representative standard stereotypical stock textbook No, no, no...something contextually entirely different. A "classic" car is old as crap. My A-cat is not old. To infer that an A-cat that is only a few years old is a "classic" is just terrible marketing for the class, bad for boat resale value, and marginally insulting (it's obvious that the "classic" moniker was conceived by people who owned foilers). Besides, the real "classic" a-cats have always been the higher weight wood a-cats that even have their own portsmouth rating. Full Foiler, semi-foiler...something like that. We essentially have two different classes of boats. While it's likely that the future class will eventually be all foilers, that isn't set in stone just yet. Even the non-foiling A-cats are a genuine pleasure to sail and unlike what happened with the moth, there really isn't another boat that competes with the features of either a-cat variation. Maybe the foilers should be the ones that get a new designation - let's call them A-cat-BMWs. (Buying My Wins)

Or "low-riders"?

Posts: 69 | I kinda like low-riders. The problem is the older C board boats still foil too, but not very often. I watched Ken Marshak foiling upwind one time on his 2012 DNA C board boat when sailing in heavy air on a close reach back to the beach. It wasn't stable flight but it was definitely getting up there. And here is another video of him sailing in heavy air and trying to get air born by mistake. https://www.youtube.com/watch?v=qzgmXL32U5slow-riders is fun. | | | Re: The new DNA F1 A-cat

I thought the old boats were called the intergalactic fleet? "Intergalactic" started when the ISAF started giving people fits over using the word "World" in the event name. They threatened to ban sailors that participated in any sailing event with "World" in the title that wasn't an official ISAF event. Hence, some events started calling themselves the Intergalactic Championship instead. I think the Hobie Waves did this a few times. I suspect in this case, that the A-cat "Intergalactic" event is another phrase we owe to that humorous Swedish John fellow

Posts: 12,310 South Carolina | I keep coming back to something like "A1" and "A2" for the foiler/non-foiler but the dad-gum manufacturers have been numbering their models with number designations that this would be really confusing. Maybe we need a couple of sponsors to make us like Busch Cup and Sprint Cup

Posts: 6,049 Sebring, Florida. | I see the T rudders on this boat, but how are they adjusting the tilt of the daggers, or are they not? I didn't see any mechanisms on the hulls to adjust the rake of the boards/foils.
And I agree that adding a hard wing sail would make it even faster, but then you're really going to need a lot of help launching/retrieving it, more so if you have to insert the boards from the bottom with a full wing up on top, going to be a pita, and you'll need a big box to store the wing mast in too.

Posts: 12,310 South Carolina | Rudder rake adjustment: ![[Linked Image]](https://1.bp.blogspot.com/-5G2avbSLRdU/VwrT43Fr6sI/AAAAAAAAnCc/7-qo1yiM_hostQpZGfhxnkCuIQU-CWV-w/s1600/2016_DNA%2B_F1_A-CAT_m.jpg) The top red plastic piece slides fore and aft to adjust the top of the daggerboard / daggerboard rake. Presumably there is a threaded wheel / line mechanism inside the hull to adjust the board rake. Here's a LINK to the bigger picture.

Posts: 6,049 Sebring, Florida. | Ahhhh, there it is! Thanks Jake. That is one slick looking beast!
For you guys who do foil, how much time, or how many times do you need to adjust the board rake while under way? Can you do it while out on the wire, or do you pretty much know about where to set it based on the wind/wave conditions, then set it and forget it? Is there an upwind setting, and a different one for downwind?
And once you set the starboard board, do you then have to crawl across the tramp to set the port board to match, or do they both move with one line?

Posts: 5,590 Naples, FL | wow.. is that a fish-eye lens on the camera? It almost looks as if one hull is longer (the near one) than the other (far one)...
Just looking at this gives me newfound respect for anyone who can fly this thing effectively with only two hands... let me think: - adjust mainsheet/traveler - adjust diamond tension - adjust downhaul - adjust daggar depth - adjust daggar angle - adjust rudder rake/angle
oh yeah... and steer, trap out, move weight around, etc.
How the F do you keep your "head out of the boat" with all that going on?
