      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.

  1. Garmin Instruments - Any Experience

    On the mast we keep info to sail the boat as fast as possible: BSP + TWA (sometimes AWA upwind) w big numbers. This correlates to target numbers posted in the cockpit. Upwind we talk target BSP, downwind target TWA. Also on the mast TWS/TWD + PolBSP% + sometimes VMG + HDG naturally. In cockpit we focus on tactical numbers. Most come from Expedition. set/drift or damped BSP/SOG HDG/COG to figure out current/tide - and to hit max/min time on starboard /port (to get a feel for where we are on the course), time to laylines BRG/RNG/time to mark TWA next leg = sail choice talk Depth All numbers are on the navigators iPad, but shorthanded it's nice to have on the displays + it keeps the stress level down

    The biggest reason for me was quality. We burnt through 7 Nexus sensors (4 on the J/109 and 3 on the J/111). Second is to replicate a "standard setup" to get proper help with calibration. Also, it's always fun to move through-hulls around Here's the status right now (Swedish): http://www.blur.se/2018/02/26/j-111-blur³-bg-h5000-installation/

    Guess so. Naturally, there are boundary effects around the hull, but the flow here should be laminar with perhaps 1 mm or "barrier layer". The tip of the wheel is well beyond that. With the original mount, you create turbulence that seems more unpredictable than anything else. And it's not a coincidence that the mounts have looked the same for 50+ years (should we guess it's because they're easy to mount)? We're now changing to B&G, and they/Airmar have no problem shipping a flush mount

    Why? The primary reason is to get it on the centerline, to get the same reading on both tacks. Then the flange doesn't work as intended. Bonus is lower resistance :-) I guess the "barrier layer" behaves differently there since we got it to perform extremely well on both boats.
  5. Douses on a 105

    Two on bow where the first guy jumps down the hatch with the chute and later checks that it's in order to be rehoisted. Second guy focus on tack and goes back to hike when ~30% of the kite is left and under control + help jib/genoa over the lifelines. Weight is not an issue vs a clean rounding and 100% hit-rate Same on J/105, J109 and J/111.

    I would say it's essential if you want to get 100% out of a modern cruiser/racer. Especially if you're getting into a new boat that lacks a good local OD fleet and have limited time (who doesn't). There's no way to find crossovers, optimum VMG or evaluate the difference in trim or crew placement without proper instrumentation. Or see if you're lifted or not without a compass. Often something that feels worse is actually faster, both sailing the boat flat upwind as well as soaking downwind. And I still havn't met the guy who kan feel the difference in current down to 1/10 of a knot. Looking at the top boats in a competitive fleet like C&C30 or Melges 32 this isn't really a discussion. ALL boats have this as a top priority. Even more so in offshore classes
  7. Garmin Instruments - Any Experience

    An unusual approach if you want a data-driven approach to performance and decision making? We find that data is good 99% of the time (Nexus/Garmin NXR w best practice calibration) and is extremely helpful for performance analysis vs targets, starts, next leg analysis, routing etc. In post-race analysis, it's common that we were wrong and should have trusted the software On charts, if you want to use Expedition or a "normal" plotters you have to get Navionics (or C-MAP) to work. I find it mostly comes down to settings and procedures for zooming (re the advice from the Vestas report). I have no issue getting the coloring right in Navionics. Use both Transas and Seapilot as excellent complements on iPad. BTW. This is our typical race course - so we tend to be somewhat picky about our tools Different approaches to details/zooming, but no major difference in shading or usability.

    How was the luck with calibration? Every system has its pros and cons. Nothing is perfect. Have been running C-MAP (in Expedition) and Navionics (on Raymarine e7 - now being replaced by Zeus3 - and iPad) without any issues in the worlds busiest archipelago races. Prefer Navionics because of plotter sync and some other cool features. Also, the update rate is pretty awesome.
  9. Doyle Cable less Code Zero

    Latest feedback is that it's hard to achieve the same AWA as with a cable, where it's ok/fast to sail with a large bubble in the luff. But the cable less code have a number of other benefits (versatility, weight, ...) Good: no need to replace the current IRC code 0. Bad: the leach still looks like crap :-)
  10. J 121

    Except that you get rid of it downwind and in light breeze
  11. Garmin Instruments - Any Experience

    :-) most of it is gone. I flushed it, but with the original mushroom housing on both the J/109 and the 111.
  12. Did you hear anything at the boat show about likely ratings for the 121, in any ratings system? Or likely comparison boats? 

    1. Blur


      Nope. Some talk re water ballas or not, but no specifics.

  13. Garmin Instruments - Any Experience

    We've used Nexus/Garmin for both the J/109 (5 years) and the J/111 (6 years) but with a busy schedule, we get approx 2 years out of some of the components (wind, log, HPC-compass). If you have a good service contact it's definitely an option and good bang for the buck. I think the new Garmin displays are superb, but some transducers will have a limited lifespan. Wireless might be an option, but I still advise people to use cables to be able to hunt down problems. I'm right now replacing it w B&G H5000 which is probably overkill for most. And there seem to be lots of people who need spare parts for their Nexus systems

    Just visited #5 at boot Düsseldorf, going to the east coat in UK. Was there with Fredrikj from Stockholm who's going to get #10 in may. Photos at the end of this gallery:
  15. Doyle Cable less Code Zero

    We've been talking with both Doyle and North Sails (new Helix Code with same principle). I can understand the benefit of being able to use it both with a loose tack as a reaching gennaker as well as a code, where you get rid of some of the mid girth / shape by pulling excess material into the luff "ellipse". What I'm trying to get answered is TWA range or max depth compared to the "standard" 75% code allowed in IRC. Any experiences here. Today, we run a 50% super flat code in our local handicap system, but for IRC we need/use a 75%. The Helix/cable-less might be an expensive addition/replacement just to push TWA from 80 to 85 :-)
