Well if it doesn't get sailed against comparable boats it's never going to be properly tested. Almost any boat I've sailed feels ok in itself, but some feel great. So whilst all the following boats might seem fine when sailed in isolation, After Comparison, some might prefer Cadet to a Mirror, or an Ent to a GP. Some might like the 5o5 more than a Fireball and some a 29er to an RS500. The point is that you can't really tell without direct comparison. A large measure of the success of this design concept must be whether it does the things I listed better than the nearest comparable boat. (I accept that Graeme has done it for himself not us and in that sense it might work for him). If it doesn't, then what's the point?

Well with any luck, tonight might be the night I finally get to find out if the weather holds and it's not sheeting with rain and likely to freeze my butt.
But already it does enough of the stuff on that list, It must be faster than a bloody Vortex upwind, I've had to double the size of the jib, that Vortex sail is so Gutless and the few minutes prior to that video being shot where we did have some wind and a boat to compare against it more than matched a Contender (not that light wind and a none trapezed Contender is anything to shout about) in ability to point whilst still making the same way for that short period. Stable? Can you walk right up to the front and untangle the spinnaker without batting an eyelid in a Vortex? Easier to handle ashore? No it's not, one of the weaknesses is the lack of any sharp edges to grip everyone has asked for somewhere to grab to help it up the steep shingle at high tide. It tacks OK, it's ponderous like a Blaze, but the jib helps assure you it'll go round, it missed a couple of very low wind go a bouts with the small jib on the lake, then I spotted the centreboard wasn't down. Aesthetics, well they are in the eye of the beholder and I don't mind the way the Vortex looked, would indeed have owned one had it been more beach friendly as you know, and in truth it was the Vortex that inspired me to try something the same but different. I'm not 100% happy with the way it turned out, the snub nose serves no purpose because of the way they manufactured it, the design called for the pole to come out through the nose hence it being wide for the pole to swivel, but manufacturing constraints at the time prevented that. Other than that the colour choice Black and Red were mine . But until it lines up on a half decent start line with a half decent breeze and half the systems working properly, I'll not really know and if it doesn't then I'll have to take it apart, flip it and rework the under hull to see if I can improve whatever might be hindering performance.. It does work at least, even in the crappest conditions it can get round a race course when it might not have even managed that, the plate & rudder could have ventilated and not functioned, the balance could have been so screwed it just wouldn't sail and remained head to wind or bearing off continually. So either way it's still a fun project and better than trashing myself trying to make someone else's mistake go better with my limited time, ability, body mass and now inland revenue reduced funds and it's taking way longer than it would if it were being developed by a builder with access to decent water and rescue back up, but even so, cast your mind back.. How long would it have been before they put retracting centreboards and mast tracks in racing longboards if I hadn't cut a TC39 about in 79? Would Roger Tushingham and Lester Noble have broken through if I hadn't designed and had Parkers build a round board... Someone has to try this stuff, as it was it took until 82 before those things were in general production (the retracting centreboard, by 83 round boards were dead in the water mores the pity) so I'm recapturing my youth all over again probably thanks to the onset of senility, like I said to Andy Patterson on Facebook last night (he had a picture of the 88 Moth Euros that I RO'd) if you'd told me then what I'd be doing twenty years on I'd have sworn at you then said something like "put me down before i get that mental.."

it's ponderous like a Blaze ..
?? How on earth were you tacking your Blaze then - all you needed to do is keep your weight forward in each tack and make sure tha rig rake was set up within the guidelines. Do it wrong and you will be s-l-o-w for sure but the idea is and always was to keep the stern 'UP' with this sort of hull ... I'd have thought with your weight this would have been a doddle. Some people seem to have the rake all wrong which can slow up tacking as the overall balance is all wrong - can you recall what the settings were ?. Incidentally I cut a fully retracting c'board into one of the first Tornado hulls to get to the UK (board that is) to great advantage around the same time or very slightly later as you were hacking the TC39 ... coincidentally that was the first board I defected to from dinghies ! (I think about £ 200 all in and brand new !) I also had a Turbo ... but it was not going to last long with the rate of development at the time and its durability proved a bit 'iffy' ..... old history now. btw I don't think you will ever get the vortex rig going that well - too small, too flat and far far too heavy and unresponsive and 'draggy' . Should have gone with a slimline 'nice and simple' Blaze or Halo rig ... and preferably in carbon ;-) Mike L. |

I meant in the same way that rack to rack is a bit of a mission, it is very reminiscent of the Blaze.
had another Jib mare tonight, the thin spectra I'd used to save weight doesn't jam so well in the cleat when wet, and the kite halyard I managed to trap in between the main bolt rope guide and the mast, not to mention my new sheeting system totally un ravelling just as I launched into the shore break,the wind also dropped and went dead offshore, nothing like launching into breaking surf, with no main sheet or shortly after no jib control either.. One day I'm going to get it all working. I did surf a couple of biggish waves tonight without the slightest hint of nosing under, it was bloody horrible on off wind, hail storm and it had looked so promising earlier, so typical, just as the gun goes, so does the wind....

Hey Graeme - As I said I hope it does something really well and so leads a big advance of some sort. The retracting centreboard on a windsurfer must rank as the biggest advance I've personally ever experienced - transforming the near impossible task of getting downwind on a big board into a joy.
Masttracks were another. Lets hope we have a similar revelation to celebrate soon. The Vortex is pretty quick upwind in all but very light conditions. I'd agree the sail is a little flat - faster in a breeze of course. The tip for lighter breezes is to have the lowers bar tight - so that with no kicker, the mast is either dead straight or even very slightly inverted. That helps the leach stand up, keeps a bit of fullness in the sail and so powers it up significantly. No cunningham whatsoever unless overpowered. (Quick tug to 'smooth creases' then let it off and leave it). Of course its not cut to be used with a jib, but as its quite a flat entry, I can't see that being a big problem. And yes, I can go to the bow on the Vortex - often do between races to adjust rig tension - but wouldn't dispute that the V twin will be more stable when thats needed!

And yes, a bigger carbon rig would have been better - you skinflint!

I always felt that flatness of the sail was due to the mismatch with the RS700 noodle mast, I don't think I've come across anything as flexi in dinghy land.
how can you "go to the bow" when there are two? and correct me if I'm wrong, but they sink don't they. ![]() Hindsite being the exact science I'm all too frequently familiar with in my life, I should have gone with an MPS rig and bunged a small jib on that, then I would have been closer to what I set out to achieve in the first place, but hey ho, it is what it is. Interesting point, at what wind strength does the vortex act anything like half decently? I can't see it totally sticking like the V2, there's hardly any wetted surface to stick. And when it does go slow, how slow is it? Laser Slow or something worse (nothing springs to mind).

If it's any consolation, in sub-wiring wind and I could beat an asymmetric one in my Vareo..... over the water.

Ah. there's a thing, then we're close, down the lake the only thing I occasionally got past was a vareo, and I managed to stave off a laser last night even without a working jib, it's pathetic really all this, it's too heavy, has too much wetted area, I can't lift it onto the trailer without help, I should give up, admit it's a two hander, put a sensible rig on it, see if I can't blag an ex Olympic 49er set up, then we'll see some action...

As with all these things, 'It depends'.
a) On who is sailing it b) On where it's being sailed c) On the course So if a good sailor is sailing it on a big lake with a one tack beat, and offwind legs that just suit the asymmetric, then I'd say it will beat an RS400 over the water in winds of say 3 kts +. BUT If its sailed by a beginner on a small shifty pond then it will potentially fall into the clutches of RS200s and Vareos in any winds. In less than F1 its a dog - no other word suits better. In F2 its very sailor / course dependent. In F3 its exceptionally quick offwind and if trapezing (IE not a porker) quick upwind. In F4-5 its very quick off and up wind, but waves downwind can catch you out. In F6+ Its very quick upwind - but steep chop /waves getting to be an issue. Its very quick downwind but waves are a BIG issue. I don't know of any trapeze boat that's really good on PY in light winds - it's not their thing. The Vortex is no worse than most. No it doesn't sink when I go to the bow(s). It suppose it might if I tried to 'hang ten'. Anyway, I'm still intrigued to see how the V twin measures up in terms of speed and manouvreability. |
