      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

    Just spend more time on deck, Duncan! Just cos you're an old bloke doesn't give you a licence to curl up downstairs the whole race...
  2. what is it?

    Just correctin'
  3. The 70th Brisbane to Gladstone race.

    Excellent, and you can still hold a flaccid penis in one hand anyway.
  4. The 70th Brisbane to Gladstone race.

    I think we need a thread that combines IRC, Yachting Australia and Foiling so the Demon and Doug can find a home together.
  5. Sydney to Hobart 2017

    So Keef is an A4 or the A3?
  6. Sydney to Hobart 2017

    Oats has no option but to sail deep as they simply haven't the righting moment to sail tighter angles. It's very clear how much lower they can sail from those plots - thanks forthe post Duncan! Naturally, the Indian's optimal angles will always be much higher as it needs to exploit its big RM and reduce wetted area through running heel angles. Hence WOXI runs loose luff kites as well as zeroes. The Indian only runs Xeros, ditto Blackjack. Blackjack could well benefit from some big loose luff kites as it has even less RM than WOXI and is lighter.
  7. SuperFoiler Grand Prix 2018

    I hope you're right and that the entire fleet gets close in speed and capability but look at the personnel on Euroflex. Light years of hig speed foiling experience and I'd suggest a hard act for anyone else to follow. Proof will be if more Adelaidians come out to the next edition, too early to claim victory or defeat yet. I hope the fleet does get some respect up on the GC, the risks of a collision or wake-induced capsize are pretty high for the boats and sailors.
  8. Sydney to Hobart 2017

    Nah, Riechel-Pugh. Loki, Limit, Shockwave, Bella Mente, Moneypenny and a few more IIRC. Around 2005-6
  9. SuperFoiler Grand Prix 2018

    I hope it succeeds too but I fear the whole concept is fundamentally flawed: Boats are way too difficult to sail. This means that even competition is a long way off simply due to capability gaps across the fleet - even at this high level. If it's close and even toe-to-toe competition that punters find engaging, SF is a long way from being able to deliver that. There's a reason why most match racing circuits use easy to sail boats like RC44, MRX, Darings, Elliott 7s, whatever. Boats are way too bleeding edge - technical issues a long way from being sorted at this point. The whole scheme will be a money pit for a long time as the bugs are sorted out (e.g. the speculation about rig size above) and the spectacle will suffer continually from breakdowns and risk losing audience interest along the way. Boats too unforgiving - one capsize and that's the end of the race, potentially a series, with a real risk to crew safety and integrity through capsize-induced injuries. At least an aydeen crew can get back on the bike unassisted in a rapid time frame and get back to business. Boats too fast - crew on trapeze and risk of collisions with serious implications is too high to allow really close racing, related to points 1 - 3. We barely saw any toe-to-toe stuff in the Americas Cup, and look at the resources devoted to that. Chances are SF crews (even if they're AC veterans) won't be drilled enough to be confident taking much risk at all - they have careers to think about. They'd need to train full time for a year to be as sharp as AC crews, and the boats are every bit as edgy it seems. Boats have no spinnakers, related to point 4 - they obviously can't carry extras given the performance envelope. Punters understand spinnakers / extras and think they look cool, plus commentators can talk about sail handling to fill space, plus sail handling becomes a variable in the match racing eqation whereas it isn't at present. Most other match racing boats have extras. even the M32s. Boats too narrow band. Boring when they can’t foil, dangerous in over 15, big waves will cancel racing. Risk of entire events being lost to weather is sky high. That’s not a recipe for commercial success
  10. Sydney to Hobart 2017

    One of the more suprising things I've heard from a protest defendant...

    What do you get when you divide those raw percentages by the delta between the boats two handicaps? IRC, ORCi Inshore and ORCi Offshore. You get a measure of competitiveness between the two worth betting on.
  12. Club/offshore racers in Aus up to $80k AUD

    That would seriously harsh my mellow
  13. Club/offshore racers in Aus up to $80k AUD

    I found a mysterious button in our new Cookson 50 during the Coffs race that does the disco light colour change thing wth the lights. That was a huge value add...
  14. DD, having had a chance to put the Cookson 12 (Voodoo ex A cunning plan ex Blackadder) around the course a few more times it seems the thing's a rocketship under 10kts breeze, but struggles over 15kts (even with 850kg on the rail). Also I have q's about Assy v Syms on W/L courses...with a narrow waterline I get the impression a smaller Sym would be better.

    Before we start doing mods to chase handicap reduction, I'd value your thoughts on set up and next steps. Here's what I know:

    VooDoo                   1.136   Assy + sprit                     154m²

    Philosophers          1.138   Symm + Pole + sprit      138m²

    Grace O’Malley       1.130   Symm + Pole + sprit      140m² 

    Powerplay ??           1.130

    Avalanche                1.145   Symm + Pole + sprit     135m²

    I’m trying to find the IRC ratings for C12’s with short rigs:

    Sail Exchange (ex- About time)

    Occasional course Language

    Any input is valued - Cheers Couta

      Hi there - is it Hugh?  David Eastwood here.

      I navigated About Time and was in charge of data, polars etc. for 15 years.  The previous owner, Julian Farren-Price is very well tuned in to C12 modding of course and I'm sure he'd be happy to talk.  If you give me your contact details I'll ask him.  david.r.eastwood@gmail.com

      Net-net there's a major configuration difference between the earlier and later C12s.  SailExchange and OCL1 were built together in 2000, and were the last two built with the original cast lead IMS keel.  The later boats are more powered up with deeper steel fin / bulb keels and bigger rigs.  Unclear to me that this is actually an improvement as it's always seemed to me that they struggle a bit to sail fast enough to offset the big rating hit.

      I have relatively recent IRC certs for ex About Time, though all the detail you need is visible on the current ORCi Cert too - that's public domain and free of charge.  Go to ORC Sailor Services, set up an account (free) and search for Cookson 12 in boat type. 

      Shane Guanaria at Doyle Sails ran our sail program for many years and will also be a useful person to talk to. 

      At your rating you should be regularly hitting 7.3, maybe even 7.4 upwind in good breeze.  As you're new to the boat don't underestimate the experience factor, they are tweaky and no doubt you will sail it faster than you are now as you become more familiar with the boat!  850 is about what we carried on About Time when sailing 10-up (fat bastards...) so maybe even heavier would be worth thinking about?.  That said, not much room on the rail for another body...we sailed 9 up whenever it was light - medium.

      SailExchange rated 1.114 last I checked, OCL 1 a bit lower (has a heavier rig and motor than SailExchange).  You won't get Voodoo that low with the big keel and rig, however.  I'm guessing, but if you could get it down around 1.123, say, you'd be looking very competitive. IRC ratings are also public domain: https://www.ircrating.org/racing/on-line-tcc-listings  Not much detail data in there but download the complete spreadsheet and the right combination of length, beam, DLR and age date filters should pick up all the C12s currently rated worldwide.

      I'm reasonably familiar with Grace O'Malley as it was, having sailed it with the previous owner Rob Drury and having talked through modding the boat before their Hobart division win.  We delivered it back from Southport mid last year together and it was clear the drag from the deep keel and big bulb were very significant, it felt notably less slippery than About Time despite being allegedly lighter.  As a result he modded the keel, which seemed to work well.  Rob would have some views too, and I'm sure he'd be happy to share them.  Grace O'Malley is possibly not as light as its certificates suggest, I spotted some big measurement errors (e.g. 600kg discrepancy between IRC and ORCi displacements...) in that boat a few years back and it's unclear to me that they are entirely rectified yet.  Looking at its displacement, keel depth and righting moment together those three seem a little misaligned compared to other C12s.  It shouldn't be as stable as it measures in under ORCi at that displacement and keel depth.  Its interior isn't any lighter than any other C12.

      IMHO Sym kites are definitely the go on C12.  These boats aren't light or stable enough to really get up and boogie under an A-sail like say a Fast 40 or TP 52, but, sailing relatively fat angles under Symmetrics they can surf much earlier and better than IRC leadmines like Beneteaus etc, or even Sydney 38s, which gives them an advantage sailing under IRC/ORCi.  We were fully competitive with TP52s downwind until they started planing.

      The displacement on Sail Exchange's ORCi certificate is pretty close to the right number.  Within 30kg or so I'd guess.  We set it up with a short sprit for a Code 0 and long-ish pole (same length for measurement purposes) and that worked very well.  Our biggest kites were 132 sqm.  Code 0 was 80sqm and fractional, we made that call based on limited stability. We had a 125sqm A3 we flew off the little sprit but didn't use it much.  I understand that Carl Crafoord, current owner, is talking to Shane about a masthead zero for the boat.

      Years ago we reduced the main on About Time and detected no obvious drop off in light air performance so that's an option.  That said, we sail very well in the light, many crews don't, so that may be what offset the penalty.  If you can back yourself in that way then there's a potentially lucrative avenue.

      Do get the mast weighed if you want to race under ORCi, every bit helps!  The rig we put in About Time a couple of years ago is an absolute glamour, stiff as and weighs 156kg, around 20kg lighter than yours I'd be guessing.

      Peter Sorensen's boat, Philosophers, is moded very differently.  Has a massive bulb and is a lot heavier than most other C12s.  So far it's been unconvincing, and he's an excellent sailor with good crews.  Very fast upwind in any breeze, but pretty slow in light to medium airs and we were much faster downwind in About Time as we were a lot more slippery.

      We looked at About Time's configuration pretty much every season, and slowly optimised it over time, but were very focused on our program and aligning the boat's performance to the sort of racing and weather we expected.  We'd have moded it differently were we planning a Hobart tilt.  (That's what our new boat is for...) You probably ought to think through the program goal and its implactions for Voodoo mods, as there are plenty of options.

      G'day David - It's Andrew Coutts here - sailing with Hugh Ellis (Voodoo owner) and with Dave Allen running the program. There's a small core crew apart from Hugh with lots of experience (ex AC, ex RTW, ex Farr40 OD, ex, ex ex...). I'm just getting to know Hugh and get a real feel for what he wants to do...not just with this boat (training platform) but in the future. He has the means to do anything(!) Right now I'm hearing competitive "Syd -Hobart" alot in the conversation. He got burned with the Avalanche fiasco and wants to put together an under the radar "moneyball" team. I'm taking him at face value re the C12 and want him to achieve its potential. I'm not on any payroll - just an ex, ex, "back in the day" serious racer that doesn't want to see another owner "burned".

      You're absolutely right to say "think through the program goals" as irc W/L racing is a totally different config to an "offshore" like the hobart. 

      My thoughts regardless, based on 10 races are: reduce the main & go Sym with a smaller kite and retain the small prod for code 0. The optimisation beyond that will depend on the program.

      I'll chase the certs and details as you've suggested to run some scenarios, but as you said, it comes down to the program. Dave & I will be working on that once Hugh confirms.

      Really appreciate you taking the time to share this info David, restores my jaded faith in the sport!!!

      Thanks again


      PS with a moniker like "Dick Dastardly" you and Hugh would hit it off - The latest addition to his personal fleet is a Grainger 60 that he named "Muttley"!!

      Ha Ha!  Very welcome Andrew.  We're nice guys in this program.  We figure it'll pay us back.  When we bought Terra Firma (now About Time) we got a lot of help from the Melba community in giving us intel on the boat.  Have to say, we now know for sure that program was seriously dodgy on measurement...but that's a whole other story.

      One thing I forgot: remeasure the sails annually.  They shrink! 

      A couple of IRC certificates attached - the About Time one reflects the boat as it was when sold to Carl and renamed Sail Exchange.  Note the different hull factors, you should aim to get that as low as possible.  I'd say Pazazz HF is too high, can't recall whether that boat has an oven and a table, cushions etc, About Time did, very deliberately.  IRC rating is pretty sensitive to hull factor, and while Voodoo has plenty of visible carbon in the interior, as far as I am aware it's purely cosmetic and there's nothing tricky about the interior structure.  I'd be arguing politely but firmly with the IRC Rating office about that number if Voodoo HF is higher than 10.0 assuming it's fitted out as About Time was.

      Pazazz was re-weighed late 2014 after team About Time pointed out some strange anomalies (the 600kg delta I mentioned)  in the certificates to Rob Drury.  The IRC boat weight on the post-reweighing cert at 5072 is still 200kg above the ORCi displacement at that time (4864).  The freeboards must be screwy in ORCi, or the scale which weighed the boat in 2014 was massively out of calibration, or Rob was cheating and had more gear in the boat than allowed when it was weighed (I've known him over 15 years and that's very unlikely).  It's very important to check the ORCi and IRC displacements - they should be very close as the measurement conditions under the two rules are essentially the same. If they're not, ratings may be materially wrong.

      I see all the local C12s seem to have current ORCi certs so you can sharpen your rig and optimisation thinking using the data in there. 

      Comparing Voodoo and G.O righting moments, there's definitely something odd going on.  How could G.O be 150kg lighter than Voodoo, have 4mm less draft and have a 10% higher measured RM?  Makes no sense, the interior fitouts are pretty much the same (I've seen them both), keels are the same.  If Voodoo's rig is heavier that may explain things, but I suspect it's identical to G.O too.  That said, if the inclination done on Voodoo way back when came out assessing it with less than actual RM, expect a rating hit if it's re-done properly.  Sleeping dogs...

      Pre and post keel mod ORCi certificates for Pazazz are also available on the ORCi database for reference.

    Wasn't the 55 stuck in some sort of insurance related vortex? Surely that'd have been resolved by now, it's been a couple of years at least. And yes, the 42 was a lovely piece of kit too. Where did that end up?
