It's pissing down outside and yes, we are back to Level 3. To all those moaning and bitching about it and calling the PM childish names, get a grip, we are the luckiest people in the world right

They towed out around 11am and the breeze was light and puffy to start with. Foiled down the Channel and headed out to the Bays. The breeze started to build around midday and they got some long runs i

Yes, quite light but I didn't see all the afternoon's sailing, can only comment on later in the day, when Britannia 2 was running a #1 jib and foiling around no problem. They look quite quick at times

Crikey you make Smack look classy.

Coming from the guy that has nothing better to do with his time than hurl insults at Me. 

I get it. You think I'm a "fanboy".

I am, I'm a "fanboy"of ETNZ. Have been since I went to Auckland in 1987 and welcomed KZ-7 home, and 30 years later welcomed ETNZ home even though it was pissing down with rain. I'm also a "Fanboy"of the Black Caps and the All Blacks, and I'm proud of it. Sport is better when you get behind a team.

I'm also a taxpayer and I don't care that my tax goes toward a sports team that I support. I'd rather that than it going to paying for a fucking terrorist to get 3 meals a day and a roof over his head for the rest of his shitty life. But that's not my call, and I accept that. So Dalton can wear as many hats as he wants, and pay himself what ever he thinks he's worth as long as he wins and puts on an event Kiwi's enjoy. Thats his job.

If you have a problem with the team/ Dalton taking tax payers money, that's your problem, deal with it. But its not going to stop it from happening.

Taxpayers money is going to the team and the event, it already has, so you might as well get over it.

I don't care if you want to call me names like a 5 year old.

Insults from nameless, faceless anonymous posters on an internet forum don't bother Me. So you're wasting your time if you think your little insults are going to get under my skin. I come on here because I want to, not because others want me to, or don't want me to, just like everyone else does.

Like I said, I thought SD should've stayed.

But what ever.

Carry on.

There are a lot of people, myself included that thought SD should've stayed. I don't care if he's a troll. I really don't. If he can take it like he dishes it out, I have no problem what so ever with it.

Thats what the Iggy is for.

I don't give a shit if you agree with Me or not. Thats the great thing about the internet.

If you do, Great. If you don't, Who gives a shit?

quit moaning like a 5 year old because I say stuff you don't agree with. Put your point forward and be prepared to debate, Or just use the iggy

button. Thats what its for.

Sheesh. Its like its rocket science for some people.

Since its been a point of debate in the Amway thread: TNZ got some mighty slender little spreaders.

wellll, maybe discussion?

but i'm at a real computer tonight so i thought i'd do a bicubic zoom of the bits. looks like a control rod running up the mast to just below the spreader. serious voodoo.

Honestly, I think a lot of the furor over use or misuse of NZ "public funds" is because NZ does not waste enough public money in an absolute or percentage sense. We're #1 in that and now that we're also world leaders in covid we don't fuss over a wasted billion here or there. ;)

nice effort :D

First rule of drawing ... make sure you have a flat piece of paper

the boat is not square on and it's slightly rotated away from you, the section of the mast also reduces in the to 1/3rd or so, I would imagine the Flat section of the D needs to be built straight so pinch the line to the back of the mast

from this view, there seems to be a slight consistant Bow

here is one I prepared earlier

I cheated on the mast line. I did a selection on the highlight and filled that -_-. I used Photoshop, not really the correct tool. Am proficient in Maya for vector, but again not quite right.

C’mon, why try shoot this messenger? My take on the BV report was an eyebrows riser much like what this Kiwi took from it. 
 

‘Good headlines’ but wtf? is basically what I originally posted, this article agrees. 
 

I don’t actually care if MBIE loses the argument or not but the subject is headlines in NZ for now, why should we here ignore it?

from the transport pictures they look to be straight ... easy to get some flex into the mast if you design it to be that way

 

looks like ETNZ have opted for the smallest length allowed at the upper mast plane of 2.6m

Yep, they've headed back in.

It was rather unexpected - they came up the harbour at speed, looking very normal, with only one chase boat then just kept going. Eventually the rest of the chase/spy boats followed.

That's a good article, it puts things in a much broader context.

The government contribution is from the Tourism NZ budget - just like AC34 and -35. Now then, if Tourism NZ did not sponsor ETNZ but spent their contribution on advertising and promotional work around the world, do you think anyone in the country would seriously expect to see an accounting of exactly how the TNZ funds were spent?? Yet here we are...again. Can't help but feel there's a strong green-eyed infection behind the sneering at ETNZ.

I would not blame Dalts if he takes their AC37 Defence elsewhere, but he won't. He's a proud Kiwi who deserves a lot better that he receives from some quarters.

MBIE - and by default Dalton - really didn't have an option to keep schram after the M&C allegations, and especially after the media got hold of it and the feeding frenzy went all the way to the High Court.

And Dalts did what he does best - attack as the best form of defence.

If indeed there is much sneering at ETNZ I suspect it stems largely from ignorance of the true state of play.

I hope you realize that virtually every mast (spar, boom, bowsprit, beam, the whole boat, for that matter) bends. Wood, alloy, carbon- they all bend. The standing rigging limits, controls, and often induces bend (think backstays and runners). 170mm is nothing on a rig that length. Have you ever looked at a skiff rig? Mast bend (fore and aft, side to side) is elementary in understanding how to set up and trim a main, just as headstay tension is elementary to set up and trim a headsail. To think that the masts on any race boat would be static and straight isn't even in the conceptual ballpark.

being a 75 year old Laser sailor, I know sweet f'all about shaping a main with all those adjustments.  But I thought, naively that carbon fibre was brittle?  Looking at that picture I wonder how many of those masts go "bang!!" with shards everywhere?
This D mast has quite a big cross section I thought it would be hard to bend but .....?  The aft side must open a little when it bends? which must provide some flexibility fore and aft?

Carbon is brittle in relation to impact and point loading. But it can be layed up into very accurate and precise flex patterns. 
 

the flex/bend in that mast isnt unusual in terms of the deflection of a structure like that. 
 

realistically it would be possible to control twist in high wind by increasing the bend to free off the leech of the rig, exactly what you do with the Cunningham on your laser.

In the case of a laser- you control mast bend with the mainsheet and Cunningham. The more main sheet you pull on, pulls on the leech, which in turn pulls on the head of the sail, and therefore the mast.

Ice Hockey sticks are carbon fibre and take on some pretty extreme loads when the pros shoot with them. They do snap on occasion, but in 90% of cases its because its been slashed by another stick, or stood on with a skate.

Just a minor (now historical) tidbit from Bermuda.

I was talking to a guy from Southern Spars who built ETNZ's foils for AC35. He said they were ultra-sounding every day and the damage had got so bad they were expecting the foil to give at any moment. Their advise to TNZ in the final race was to hold back and nurse it as much as they could. The crew ignored them and went for glory.

Just like Spithill saying they had some mast breakage in the last race of the cup in SF.  They were grinding and gluing patches as NZ was practicing.  They told him to take it easy and give time for the glue to set, but he was flying 40 knots right at the start.

Dalts admitted as much after the win, said he spent a lot of sleepless nights worrying about if that set of slow, extreme-light-air foils would break. He’d also been concerned about if the wind would freshen after the 5 day break.

Love these pictures of bendy carbon fiber, and must say that I was a bit surprised how extreme they bend. They surely must be using a low modulus carbon fiber.

The AC75 rule only specifies a maximum modulus, so they could easily make it a bit more bendy, but I doubt they would like to introduce a less controllable variable.

And dinghy classes with square head mainsails seem to have gone to stiffer mast as well.

BTW, the British 12 meter Lionheart had (or still has?) a very bendy fiberglass top section.

With the correct laminate schedule and fibre modulus, carbon can bend however you want. I used to make model yacht masts and tested their impact strength by smashing a test section against the corner or a table, without failure.

Hmm, I had been assuming the D was OD -> odd that one might be more bendy than others but actually its a lot more open than I assumed

20.3

The mast tube laminate provided by Rule 20.1 (b) is a minimum required laminate.

Laminates resulting in greater fibre weight, resin content, core density, and/or core thickness than specified in the mast drawing package are permitted.

Additional reinforcements are permitted and may be external to the mast surface but must remain within the tolerances given in Rule 20.2.

Higher the modulus = more stiffness, less weight, more brittle.  Layup schedule is everything.  

 

 

the matrix/resin is the key

high temperature cured pre-pregs are massively tougher and more flexible . you will be able to achieve the similar bend characteristics with different fibers but within reason you just need less of the high modulus stuff  -- lighter

Grab from the recent video. Clearly a lot of parallax error and conditions would make a difference for VMG, but what do we think of the upwind angle here from the two tacks? Seems like they sail pretty close to the wind to me.

I also got to see Te Aihe launch off the tow - they towed into the middle of the harbor with sails up in a decent breeze.

The tow RIB eases off slightly, Te Aihe lifts the windward foil, the guy at the base of the mast lets the line go (third shot) and Te Aihe flies away ...
