    Vendee Globe 2016?

    If true, and I want it to be - a masterstroke! I guess the calc is 200kg additional weight in a symetrical foil vs loss of speed from hitting a UFO at some point... It scans if it can be inserted from deck. OTOH, would thought we would have heard about it before now - dock talk, boat tours, prepateures (spelling), etc

    Ker 43 Ptarmigan

    FWIW - UK Ker 40's were marginally slower than the Farr 45's (except Ran) on the water. Hardest conditions were mid range when the 45's were poled back and heading straight at the leeward mark. Tonnerre would be 4+ minutes/ hour further down the track. Bill, congrats on the boat and early results, and thanks for the insights into what you're doing, sounds like you've got a good programme going. Re your comment on the light airs performance and apart from the rig tune that you mentioned - from 40 experience, sail it flat, uphill and down. From memory, polars for the 40 called for 2/3 degrees of heel, can't imagine the 46 is much different. Very counter-intuitive for a big boat, and took us a while to believe it, but good for .5+ of a knot, try it off the race track.
  3. FOP - been following this thread for a while, and I am still amazed at the the standard of your work every time you post. I seem to remember some talk of getting contractors to finish the work - pleased that that doesn't seem to be going so well! I think they must have read this topic... Looking forward to continuing updates and seeing a splash at the right time - it seems to be coming together now. :-)

    Something of nothing wrt Adrian Newey, mostly as per the Guardian report. http://www.bbc.co.uk/sport/0/sailing/25653476

    Some good shots of Jungle Drum from Paul Wyeth here- linky and other linky

    I should probably be the first to say well done to Jungle Drum on todays bullet in GHWS race 10, and putting them selves into 2nd o/a with 2 races left. Guessing conditions were 5-8 knots, which would suit the design under IRC. Anyone know if they had the full strength team on board?

    Operator - you could work for J-Uk with that spin on the results! Jungle Drum finished todays race behind all of the even vaguely competitive boats you mention - on the water, nevermind on corrected. I don't know the reasons why, guessing they had an issue??? Water in the afterburners possibly? http://www.hamblewinterseries.com/results (not sure how that link will work out - you need GHWS_IRC2 under 'class' drop down, then you can select race 9 results from column header)

    Can't argue the results - well done on beating the Corby & 105 this weekend, although you did drop points to the Elan 37. Guess you've got the speedo on dealer calibration though, as in 20 knots tws a Ker 40 has downhill VMG targets of c.16 knots and sails off IRC rating of 1.195ish, similarly, a Farr 30 targets c.12, IRC c 1.090.....either your speedo's overeading, or your IRC assessment is way, way, way under..... As for the bulb - well, agricultural is probably a complement, but in fairness is in keeping with the design ethos of the rudder and hull, and consistency has to count for something. Okay, I'll drop the attitude, and attempt to be convinced for a moment. wrt the windspeed, ph suggested 18-23, you're now claiming 28? We (not in your class, but racing) saw a max gust of 20.5 during the two races at the weekend. During the two race times over the weekend, archives from Bramblemet shows a peak of 15.2 knots, Chimet 25, given the geographical locations of those two stations and where we were racing I'd suggest 20.5 is probably not far out. I can't see it now, but seem to recall bramble and chi figures are 5 second averages. If you're planning is the speedo still in the water?? Flaming mentioned seeing you lit up, bow out - that pretty much fucks with the best calibration of all the numbers. That aside, was 17.2 SOG on vmg target? What do you reckon your average boatspeed was? What do you reckon you're target bs in 20 knots TWS is? Can you relate this to a Farr 30 target of 11.94 knots target bs in 20, or even a Melges 32 at 12.9, both more powered up boats.

    That rudder shows not much design evolution since 1976... seriously - from a uk perspective, can someone explain what all the love for this this boat is about? Design - rudder looks like it will be fine if replaced by the heads door. keel looks about 2 feet short. Bulb looks to have been modeled on the end of the discarded cigar the johnstones have been smoking while laughing all the way to the bank. Really - has anyone seen a rudder like that on a (non J) new boat in recent years? OD - not going to happen for a long long while - as an example the previous J marketing exercise - the J70 - manged 9 at J Cup this year including 4 ringers - (one was even entered with the name 'FOR SALE'!!!)), and currently 4/5 at Hamble Winter Series which is J -Uk's home ground. I reckon its going to be take a while for any J88 OD to happen IRC - likewise, it just won't happen - just like the 111 it will get spanked under IRC, apart from the odd downwind passage race. towing - J-uk is currently claiming it can be 'owner trailed' - that's fine if the owner has an artic - it's over 7m and so uk legal limit for towing means a vehicle over 3,500kg, before you even start thinking about GTW, recommended max trailer height of 3.0m ( 1.8m draft, say 1.0m freeboard, 0.5m road clearance = fail) DoT codes of practice for trailers,etc etc etc Price - am I right in thinking £100k base so OTW = £125k? WTF - for that money you can buy a QT, mumm 30 and, say, X99, kit them all out with sails and get a better seasons sailing from any one of those in virtual OD, passage racing or IRC. For not too much more you could put a bolt 37 in the water. Sorry, think it's probably an ok 'ish sort of boat, but really don't get it, I'll go play on better boats. Put simply, can you think of anything else around at the moment that's likely to get OD in the near future in this size range? The Solent could really do with a 30ish foot OD, and I can't see any other contenders. No I can't, but there's plenty of OD already in the solent, in classes that have bigger events elsewhere that are easier to get to than with an 88 (really, there is navigable water outside the solent!) I also don't think the 88 will succeed in getting OD going where the 111 & 70 are struggling, despite the marketing. Would you be prepared to sink £125k+ into it? Why is 30 foot important?

    J/111 Goes Sailing...

    Cheers Jambalaya, Blur is this the boat you were talking about? Might be. Just came up in a discussione when I was in The Netherlands. Couldn't find the old results. With a bit more digging, it looks like it was the 2002 race when co-skipper of J-Xcentric won RBI 'Robin Verhoef, co-skipper of J/111, J-Xcentric is no stranger to short handed racing. In 2002, the Dutchman won the grueling Two Handed Round Britain and Ireland Race.' linky Not the same guy who got DSQ from 2h Fastnet - Henk Bulthuis in 2005. Hijack over - back to your scheduled J111 programme.....

    J/111 Goes Sailing...

    Blur Which boat/race was that? Only one I can think of from (literally) a couple of years ago is RWYC RBI2H from Plymouth, don't recall a 109 winning it, but can't find results on line atm. Actually think that 111 will make a great shorthanded offshore boat, as you say, less loaded than a more typical IRC boat, enough sail area to be a challenge/rewarding, has a rating that it has shown it can sail to off W/L courses, its smack in the middle of my ideal size range for short handed racing and has an interior that provides everything you need, without a lot of unnecessary ballast.

    Congrats, hope you have as much success as you seem to have had with the 109, and a lot more fun.
