    J/111 Goes Sailing...

    I typically calculate 2 l/h @2300 RPM. Below figures from the official test w J/composites in France & Volvo Penta.

    Yup. I will update the shorthanded ones soon... The biggest problem is that we've been racing in 5 different rating rules with multiple configurations. Also had to adjust crew weight at the crew just got fatter and fatter... Never ends.

    Great looking boat!!! Note that the ORC polars are based on wind at 10 meter. On the J/111 with a B&G sensor the height is 17.6 meter. So target speed at 10 knots in the Speed Guide is really target speed at 9.32 knots wind on the instruments. Or just add 4-6% boat speed to the target speed for a given TWS (a bit more at v3 knots and a bit less at 18. ORC underestimates the effect of crew weight somewhat; i e you will be a bit faster shorthanded in light airs and downwind where I easily beat the fully crewed polars, but be 5-10% off pace when you're powered up. Typically at 92-93% upwind. Below are our targets. As said, drive to speed upwind. NEVER point before you're on target. We've also drive to target TWA (and heel angle) downwind. Very easy to hunt for speed without increasing VMG

    J/99 vs. J/111 for DH racing

    We designed our own in carbon w Seldén, and I know some other Scandinavian and Australian (?) boats went with a similar one. NOT class legal and carbon is not in the price list.

    Bit of an overkill... but... I started out the same way but figured a black shock cord hidden in the groove on top of the boom, with just two loops coming up at the proper places, would also hold the reef lines in the proper location. When we replaced the boom to carbon, we made two of those. Reef line is lashed on top.

    I found the trick here is to mark the halyard at reef point + x cm (long enough) so you can just dump the halyard to the mark, run forward to the mast and attach the hook. We have no issues with the sail coming down other than downwind. See video below at 02:55,

    Not really. From my perspective, the J/120 is a great offshore ride, but need to stretch out to excel. J/109, J/122 as well as the new J/112e are windward/leeward machines focused on VMG up and down. Also in a handicap fleet. Not super exciting, but does the job extremely well. If w/l was my thing, I would go for a J/112e in a heartbeat. J/88, J/111, and J/121 are different, more in line with J/90, J/125 and J/145... not really great from a rating perspective, as you need to beat much bigger boats (i e J/122), but with an added fun-factor. For us the choice was similar. Coming from the J/109, the J/122 was the natural successor. But we wanted a bigger challenge, and more smiles on board going downwind. Hence, the J/111. We might have won more races in a J/122 J/boats ofthen get flack for the wide range, but they are masters at picking distinct pockets in the market, with very specific needs or "jobs-to-be-done".

    Reef. A small Dyneema loop with a snap hook, that I loop through itself on one of the pad eyes. Important that the length is right so that the sail looks good when tensioning the reef + halyard. Furling the jib is easier, as the kite fills earlier and you don't need to head up so much. My shorthanded jib is on hanks, so I kind of nurse it around, pre sheeting on the new side (ord midships). Fordeck tends to be a mess... Letterbox is the way to go. Our biggest kite is 155 m2 and hasn't had any issues getting it down. Socks havn't been on boartd since 2013.

    Guys, let me know if I can help in any way. I'd be happy to write a piece on "top 5 tips on shorthanding the J/111" or "7 things that you will fuck up when you try to push the J/111 shorthanded" But your questions/thoughts would be a great start.

    As I said; >20 knots of wind, downwind over >100 nm a Class 40 (or a Pogo) is the ride you want. For normal racing in typical summer conditions, a J/111 is 10X more fun. And often faster around the course; elapsed times from Rolex Middle Sea Race 2019; Blur J/111 d4 h12 m14 s53 Andastra Class 40/Axion 40 d4 h17 m57 s33 Crazy Akilaria, Class 40 d4 h23 m34 s31 Akouavi Pogo 12.50 d5 h21 m58 s33

    J111 v Finn Flyer 36 - IRC racing

    Where do you sail? Average wind range? W/L or distance racing? Have you seen the IRC TCC for a FinnFlyer with similar config? We've been battling with one of the best prepared/sailed FinnFlyers anywhere, "Zlatan", with a semi-professional crew. So might have some insight into both boats. Also test sailed the FF36 when it was new. We rate 2.75% higher w the J/111 in OD mode (in local single number system), and are competitive on W/L-courses in most conditions. If you want to compare times, here's a good regatta from last summer. Winds range from 20 kts early on to 8-12 for the last 3 races. For offshore I wouldn´t hesitate to go with the 111
  14. A good starting point to figure out the target speeds is to start out with an ORC Speed Guide. Find a similar config to what you got below, add 4% to most numbers (at least upwind) and then iterate from there. https://data.orc.org/public/WPub.dll/CC/113898.pdf https://data.orc.org/public/WPub.dll/CC/115946.pdf https://data.orc.org/public/WPub.dll/CC/120802.pdf That would result the following upwind numbers w a big genoa (5-6% faster than those in the brochure). Yup. To much time and no life

    J/111 sail configs in ORR?

    No hurry. We'll spend 2020 in the Med (Rolex Giraglia Cup + Copa del Rey), but it's great to have a long term plan for both the team and the sailmaker. Looks like a 55% half-width to foot ratio Code 0 will fit the LHR definition rather nicely. From my understanding, ORR tries to rate any LHR as "fairly" as possible, which makes the choice easier. The J/111 build lot's of apparent speed in light air so the 75% IRC code isn't working very well. 55% have worked very well, and we're fine with the smaller area. The J0 with 51% is not an LHR (LPG = 1.03*JLRH) but could be a large headsail. But I guess that would increase J to the new tacking point and would affect the rating in a disproportional way. In the ORC VPP, it doesn't affect upwind speed which is kind of a loophole. The number of sails seems fine. Thanks for the useful info!
