Infusion on Video

Is anyone going to distribute a polar chart for this boat?

Also, when watching the spinnaker portion of the video, I noticed the bows were out of the water most of the time. Is this the proper boat trim for this model?

Of course I have no first hand knowledge of the Infusion F18, but I can tell you that the other Flyer A-cat inspired boats like the Capricorn F18, Blade F18 and Blade F16 are all reported to be sailed best under spinnaker with the bow out of the water. This appears to make them faster. It was not expected, nor envisioned during the design stages, but in real life testing it proved to work well. Some people think it has something to do with the "reduced volume in the wvepiercer bows", but actually the bouyancy was never reduced here; if anything it was increased. The explanations are still various. Some say the wide keels allow planing others say that it reduces pitching even more because the wave contact the hulls rather away from the bows. There is no concensus apart from the fact that these new hulls like to be sailed out of the water with their bows when sailing at speed under their spinnaker.

Maybe it is just a way to reduce wetted surface area because the new hullshapes depress their sterns much less than the older shapes and thus suffer only a mild penalty in wave-making drag. More testing and theorizing is required

looks pretty seksy to me.

looks kinda wet too. I was looking for the "wave-piercing" effect that Jake referenced in the other thread, and you can see it in this video where they'd ride up one wave and just plow through the next.

Pretty cool.

Well, I guess it doesn't have "displacement" hulls in the traditional sense where waterline governs speed... But I'm far from being any sort of engineer...

Hey....I recognize that flowery red rash guard...nice form Dan!

I also really like what they've done with the fairing just before the main beam. It grates my nerves when I can feel water smashing into the front beam on most other catamarans including the I20.

Having the bows out with spinnaker relieves the helm, makes it more responsive to steering (less likely to lee helm as well) and just seems to go faster with less likelyhood of "pitching" if the bows are driven through the water.

Yeha jake,

now instead of splashing up into the air, its redirected straight into your eyes!

Darryl.

The first part seems natural, as you effectively rake the rig more aft.
The "go faster" bit, wouldn't that be largely dependent on the type of hull you have? Would this be valid for eg. the Mosquitos and Tornados also?

I have a DVD, with among others, Mitch and Herbie sailing their T. I always tought they had their weight rather far aft, but perhaps you just pointed out why to me..

I was sailing the boat in the video. I was crewing for Pete Melvin. I am in the red rash guard.

Dan

Dan, what were Petes thoughts on the boat? I know he is only going to be possitive, but as someone who has one on order, I am after all the info I can get.
How did it compare to the F18 that you were trialing with?
Are we to see pete on the European F18 circuit this season?

Paul

Not if your windward hull is skimming the water like it's supposed to.

I have not been able to access the video or the nacraeurope web site. Is there another location where I may access this video?

Thanks,

GARY

Gary - I had a bit of trouble with the video as well. I updated my Quicktime on my PC and voila it was there. Did you already try this? I was going to bring it into my video editor and make an NTSC copy (it is in PAL) but the only conversion program I found that worked left a watermark in it. If someone has another suggestion I will take it.

Paul - Pete likes the boat. To tell you the truth he seems to like all the boats he sails and especially the ones he designs. My opinion, comparing it to the F18, is that it seems to be able to carry more weight on it. The position that you sail the boat to weather is a bit back from what I am used to. Pete kept asking be to get back bit. As a crew I was behind the shroud and Pete was as close as he could get next to me. This of course helps with the pitching of the boat. Normally as a skipper I am planted about where I was as a crew on this boat, so that is about shoulder-with back. Most of us sailing both boats thought that the newer one had a slight advantage to weather and a substantial advantage downwind. You will still have to go the right way on the course as you do not have the Ferrarri compared to the moped. The downwind advantage seems to be the way the boat handles more than anything. You will be able to take advantage of the wind and swell with more swiftness. This can be a disadvantage to those that do not keep the tiller still enough to let the boat can get up and go.

Pete mostly sails his A-Cat. I do not think he is likely to show up at too many events even here. I have tried to talk him into the Formula 18 Worlds in France. He did not say no. Maybe if Jay Glaser showed interested in crewing he would go.

Later,
Dan

Damit Dan, I was really looking foreard to seeing you in your red skivies.

I can not get to any part of that nacraeurope site. I have tried different browsers. Forget about what codecs or viewers I have; I can't even get the home page at that site. And I do believe that my player is upgraded too.

Dan, are you the guy who came ashore at Belmont Shore's Claremont beach when we had a fun event known as Catapalooza last year? There was a guy and his father who had just taken delivery of a Nacra F18.

GARY

Gary,
I just tried to get there and it loaded up right away and started playing the video. I can also ping the website from my pc and a tracert takes 19 hops to get to the site from here. If you can ping or traceroute to the site try and lower your web security settings - the site plays a quicktime video automatically and maybe your settings are blocking it. Not sure if that's it but it's worth a try.
Good Luck,

Hi there,

I'm the webmaster of nacraeurope.com and it seems a lot of you can't reach the website (from America). We are trying to fix the problem, and I hope you can help me with it.

Could anyone who can't reach the website do the following (using windows):
Start -> Run -> cmd
tracert nacraeurope.com

Could you send the result (right click -> mark) as a personal message to me? This info would be very helpful to tackle this problem!

If anyone has other problems with the movie, please let me know.

greetings, John

Here's a successful one from the Tampa (FL) area.

Crashed first time and locked up Explorer. Secound time it ran. Maybe there is a bug?

Doug

Hi Doug,

mhh that's not good IE is crashing on the movie. It's programmed to show the movie if Quicktime player is installed on your computer and if not quicktime player is installed, you should get a message to download a plugin.
If you download the movie from Nacra F18 Infusion and watch it, do you get also an error?

John

Jonny,

What is your outbound bandwidth ?

I'm truying to down load and I am only getting 400(approx) kbs. I should be able to take it down at 2.5+ times that rate - Maybe you need to get some more bandwidth from your ISP / Hosting company.

Simon,

I have got no id what the bandwith is of our hosting provider. I'm currently downloading the file with 200+ KB/s (1 mb/5 sec). The server for the movie is located in the US, (gisol.com). I think the upload isn't a big bottleneck for now. If I watch te movie the download is 3x times faster than the file is playing.

Thing is that I am seeing the server as the bottle neck - I have a 10MB connection so I sphould be able to get somewhere near that D/L from the server is the states (assuming the trans-pond link is OK).

Hi Dan,
Do you feel that the bows up sailing style is faster? Did you try sailing it with regular f18 style weight distribution? It looks like they are going for a semi-planing hull shape..

John:

I downloaded it from this link.

http://www.nacraeurope.com/news_details.php?id=5

I don't use Quicktime. Use Windows Media Player 10.

If you ever get a mov you can't play you can get a classic version of Meida Player from the net. I used it to play the 3 Amigos video from thebeachcats.

Doug

I just tried it at this link.

http://www.nacraeurope.com/news_details.php?id=5

Only took a few secounds to download and run.

Problem must be with your connection.

I use Road Runner.

Gary: The boat that came in at Catapalooza was Steve Myrter and his dad. I was with Eileen on the water on the Tiger but did not want to get all kinds of sand in the boat. We launch from inside the bay at ABYC. Although, I was at the beach before that to see if there was anything going on that I had to know about.

Dave: No generally speaking I do not think that “bows out the water” is faster, on my boat (Tiger). Pete designed his boat to carry weight a little further back and it does seem to work with this boat (Infusion). Took me about 2½ minutes to get used to it, but it was comfortable enough. As far as getting the boat to plane, the feel of the boat is that it does seem to get up out of the water a bit with speed on the downwind run. Pete did not strictly design it as a planer, but there was some thought put into the concept.

Later,
Dan
