    Spinlock PXR slippage

    Has anyone had the problem or know the solution to this? Just fitted the PXR 0206 sw new cleats to replace difficult release cam cleats on my dinghy jib sheets and they are slipping up to 15 cm under mild loads. I have tried replacing 6 mm stock double braid with dyneema 5 mm and it is still a problem. Cams feel like they are sprung too lightly? Any advice appreciated.
  2. Sad old OverlayTroll dribbling on his keyboard again, always wakes up to have a kick at any volunteers or well run regattas like this one. Just wish someone would explain what OMR is so he can deal with it. Magpies at least are happy to show their feathers, this pitiful fella refuses to name himself in spite of requests. The rest of us are happy to stay out of the shadows when the debates here get robust. Sorry to have missed that good breeze John, will be back on the sacred Wangi grass once I get a boat under me again.

    F7 Folding Trimaran...This is interesting

    No such thing as a free lunch. You get what you pay for. Any other good sayings?
  4. Was keen to do so, but a boat change in the wind has me high and dry. Instead I have been trying to stay connected by keeping the OMR ratings right, just uploaded now. Some interesting numbers this year, optimising experiments have had a good trial.....
  5. That is the view of the slime tri I enjoyed most, but not often enough... Unfolded of course.

    I can't wait to see what creature comes out the "V-birth" of this development.

    Spinlock PXR slippage

    I was actually issued 2 new cleats and they are still slipping the same so have reverted to the old cams and 2:1.

    costal cruising trailerable recommendation

    +1 for the F27 Definitely the best bang for buck cruise daysail race boat out there and really defying the years on the clock. I imported #33 from US to AUS after it featured in the original Corsair video there. Over here we thrashed it hard and added a cassette rudder plus second diamonds and it is still going great with current owner thrashing it in coastal waters. With non rotating mast the lowers made it really easy to rig single handed. Peter H

    Corsair Trimaran

    And the Nuclear Engineer MultiDoubtingThom has to tell me I am having a psychological event when I try to find words for a quantifiable jump in speed that is too complex/messy for existing sailboat modelling to predict. Pumping, Ooching, Rocking, all sorts of hard to define physical actions often help produce the "breaking free" phenomenon, talk to any sailors who race at the pointy end of the fleet, they are the ones at the psychedelic end of the bar. Sorry for the apparent thread hijack, but after bhyde did such a wonderful answer, there is not much more to add, so I tried to answer the other bits in the debate. I would say go for whatever 24 footer in good shape fits in your budget. Try for drystored over floating, and garaged is even better. Bigger Dash size floats are definitely faster and also good for load carrying for cruising. Here in OZ we have a shortage of boats that size available, and bang for buck, the Sprint is probably the best around if cruising is not high on the list. Peter H

    Corsair Trimaran

    There has been a similar discussion about the way our boats behave on the new Fboats forum and I resisted answering as (believe it or not) I resisted here. For my 2c worth after owning/steering and racing a TT720, F24 MkII, F27, F22R, F28R, and racing on most of the boats mentioned here, I have found that the word "planing" does not work here, nor do any of the hull speed predictions and wave interference theories. IMHO, a better description is "break free of the complex drag on one or more of our hulls", or today I will call it "breakfree". Sailboarders have similar discussions about how/when hulls break free, and in some designs with some sailors there is a time when they jump to "glide mode", typically displacing like a div II board or raceboard edge. Other designs and sailors actually "froth" on the concave sections to make them break free before they actually plane. And in fresh winds they just about all let go completely and plane before they completely break free and touch down on a surface the size of a dinner plate with only a skeg for control (and yes they can foil on that skeg). That drag reduction is why the conventional sailboard is still faster than a foiling sailboard. This week anyway. I digressed because our boats are like sailboards but more complex. Certainly the nicest time in all our boats is when the centre hull joins the windward hull and breaks free, even if only sporadically. Sometimes the centre hull is contributing to the lift by doing a version of planing, but the lift is mainly provided by resistance of the foils and leeward hull, and the increasing efficiency of our sails. Sailing a powered up Sprint/ F82R/ F25C close to the wind for example, you can in flat water keep it oversheeted like a beachcat and drive away to load the foils and pop most hulls so only the leeward hull is frothing/blasting/knifing through the water. Careful steering through a long period sinewave can get the boat going very quickly to an endpoint a lot faster than sailing in a straight line, and VMG is lovely. We even had days on the F22R where the leeward hull while being the only one in the water, would start to plane/ break free with the right wind conditions and crew hanging out the back of the boat like your Randy. It mainly worked on free reaching conditions, and the speedo went through the roof as we passed boats that we should not have. The conditions had to be just right mind you, and I have to admit that the possibility of a few more knots across the deck while your crew are doing the wildarse thing used to give me nightmares post race. This lee hull lift in the 22 is what convinced me to not be too excited about the foiling 22, which in my little mind would have had too many days where the weight and the drag of the foils would not help the boat do anything better than it does now.

    Corsair Pulse 600

    Sailabout, you are really setting yourself up here as a moron flicking mud and references to designers and brands with absolutely no idea of what you are talking about. All the websites and forums and even google have the answers you want, but here they are again for you: The recess pictured looks like a F/C24 but underneath is clearly nothing like the mechanism and engineering and scantlings designed by Ian Farrier. The F22 is nothing like that and is totally nextgen with shorter and very different beams.

    Airlie Hammo Maggie 2018

    With a few lovely new boats joining us from across the paddock, I am really looking forward to the trip this year. I have gone the easy way again this year, operating the dive flaps and snorkel controls on McJak the Diam 24. Test sail in 8 knots last week blew my mind on what apparent wind can mean even without foils. The boom that stays in the centre all the time? Nooo. Anyway, I have just been working on the OMR for Airlie and thought that the fleet data for the first regattas would be interesting to share. OMR is as usual on the MYCQ site but still waiting on a couple of boat's crew weights. There are still some nomination glitches of course. Fantastic to see the cruising fleet so big at Hammo, I am sure some old crock will say something bad about small racing fleets blah blah blah, but I look at it as an opportunity and reckon we should be chasing some of these party-crews to join more regular real racing. Or should we keep changing real racing to get them in???? In any case they are cool people, and the vibe across the fleets in all of these regattas is better than anything you can inhale. I am thinking of refloating a Seawind 24 and getting some garden seats off a footpath cleanup and heading up there and really cleaning up. Peter H Airlie Hammo

    Farrier bought by Daedalus

    Sailabout you seem to have a fair degree of bitter and twisted and are doing the equivalent of picking on Mercedes engineers based on your 20 your old POS from a used car lot. Samc has done a good answer for but to waste a minute of my time as your Google: I owned an old and tired F24 Mk II for years and it was nothing like what you have said. Mine crossed OZ and was thrashed and then crossed to NZ and is getting thrashed and still is a great example of Farrier/Ostac (predecessor of Corsair here). All moving parts were like swiss watch components, traveller nothing like your report here. One big thing for all owners of all Farrier/Corsairs is to be careful with shim thicknesses where beams contact hulls. Refer to many sources for the document on that. Google Intrigue F24 or PM me for help if you can't manage the basics. Pic below to get you started. Perhaps yours is Mk I which was a big swerve of Corsair away from Ian's design. No boat builders here have had to do any of the fixes you have described, but the sensible place to start is the Groups.IO forum FCT, replacing the old yahoo forums, and see if some guys with similar experiences can help you out.

    Farrier bought by Daedalus

    You would need to elaborate on that pile of accusation carefully, the "I assume" phrase is just a silly way to go public. IMHO The genius of IF is undeniable and his output could be summarized by 1. An enormous number of plan built boats from plans that were always more detailed than anything else out there. Period. Until he died, the support he gave to plan builders was unequalled. 2. An enormous number of boats produced from partnership with the various "versions" of Corsair around the world. Would 453 F27's still regarded as the very best of any sailboat help you understand this? When issues related to control of production and development were not resolved amicably, IF moved on to 3. 3. A growing number of F-22 boats coming out of the NZ factory and soon the US factory that are light years ahead of any swing wing/ water stayed/ teak lined heavyweight boats out there. Production still only one boat per month, but after 20 boats things are going well. I invite you to come and have a sail on my old boat "Boom!" #1 off the production line, if you can illuminate me on any "poor production design detail" I will give you my 20 year old F28R (Boat #14) and you can look just as hard.

    https://youtu.be/3WLlZLXfa6s Yesterday's race in 15-20 knots was a lot of fun, some action uploading now to above link. We had some itchy moments on the short upwind leg, but as usual the downwind was great fun. There are some good nosedives, and some nice bits passing glamour-lead. Not on film is the main halyard blowing halfway home, froggie dynex underspec rope broke at splice where the 2:1 goes over a 20 mm sheave. Lucky the masthead spin halyard could get the sail back up to first reef point and we could limp home (still doing 13 knots upwind!!). With light stuff predicted today we started the pack yesterday and after 2.5 hours she is roadtrip ready. At 12 ish they finally got a start away for a little bay triangle so we don't feel too bad.

    No but thanks for looking. They are on a motor replacement research trial and I have seen them. Next year port will be electric and starboard fuel cell plasmadrive if Drew keeps pushing the envelope.

    Square top main

    The jury is still out in OZ as to whether the new mainsails are any better in a wider range of conditions. The only thing we can agree on is that they look better.

    Spinlock PXR slippage

    Original ropes were 6mm double braid, slipped bad. New ropes 5 mm dyneema , same. Advice from Spinlock UK is that application should be fine but they are sending another set to try. Nice guys. In the meantime racing all weekend from today so will try 2:1 setup to see if the reduced load helps. Thanks for input, I really like the cleats compared to cams.

    Latest boat headed to a mate in Norway a few weeks ago, producing recent boats in less than a month has been achievable now. Some other interesting news on this front coming soon.....

    Spinlock PXR slippage

    No, the advice was that this rotating version would be fine for typical jib sheet where the line comes aft, through the cleat, and then across to the windward side. Probably turns through 90 degrees and the cleat naturally splits that angle. The locking mechanism works just fine with adjustment, but the teeth do not hold. There is no polishing of teeth apparent. I have asked Spinlock also for opinion.

    Spinlock PXR slippage

    Definitely slipping. The cam is engaged but spring tension is very weak. If I come out of a tack and reach to leeward to push the cam down, there is no slippage. Next to useless in a single handed boat.
