    what's your top boatspeed in a J boat?

    Just saw this...some great quotes and stories! J/70's: - at 2018 J/70 Worlds, we hit 18.7 kts on Cats Pajamas on the first day...gusts to 28 kts. - others at J/70 Worlds- heard some hit 20+ kts- only 3-4 footers on Mass Bay - max known- French J/70 in Bay of Biscay- after full gale, 15+ ft waves, 20-30 kts- hit 23.8 kts with kite up J/111's: - Chicago Mac Race- several occasions of 20+ kts bursts, with full-on plane of 14+ kts for miles in the Manitous. - J/111 Worlds on the Solent- blew 15-25+ kts nearly every day- bursts over 19.5+ kts constantly. Fastest ever: - Sailing/ skippering Peter Thornton's SC 70 HOLUA in the Chicago-Mackinac Race- the year Roy Disney's PYEWACKET set record. We broke the 24 hr mark too. Huge squall / front hit just before finish. Gusts to 80 kts west of bridge in the passage. We saw 52 kts over the deck. 5 miles from finish, we set the #1 kite, wind rose in huge jumps- 10-15 kts, then 18-25 kts, then 25-35 kts, then 38-52 kts. Just before the finish line (tent on beach and lighthouse to starboard), we knifed kite halyard to drop it in a "stretch and blow", 8 guys pulled it in. Top speed as 28.7 kts, bow wave hitting end of boom, perfectly flat water. Stan Honey and crew on PYEWACKET were on the beach to watch the carnage, they saw us finish on HOLUA- could not believe what they saw when chatting with them at the Pink Pony later.

    The 1-2-1 will have the sprit completely encapsulated in a tube from the forward bulkhead aft to the main bulkhead- much like the J/133 engineering. Yes, most seals have been addressed correctly (we hope) over time. That is why there are large drain holes in the forward "sprit compartment" for J/70s, J/80s, J/97s, J88s, J/105s, etc etc.

    Not disputing at all, but what sprit change are you hoping for? I'd root for a Spectra/shock cord bobstay like many owners have added. Code Zero's and other furling headsails have/are growing in popularity, and Hall won't condone them with any previous bow sprit design. It's time for Hall & J/Boats to address the issue...overdue IMO. Not really sure what's the best way to do it, but it's not possible to run a proper "upwind" code 0 (3Di + 50% mid girth + REAL forestay tension) from the end of the sprit. That's one of the reasons we run ours "mid sprit" and even then pushing the limits. http://www.blur.se/2014/08/29/j111-blur-code-0-setup/ I'd be happy to implement a similar arrangement if I get a 121, but then with a halyard lock and a proper 2:1 tackline. As you say, this would be a good time för J/boats and Hall to re-invent the retractable sprit :-) Peter- the basic idea as you have outlined is already a design consideration. As you recall, the Ultimate 30s had a very basic, easy to operate "sprit lock" made of machined alum or SS. Discussions with various sailmakers (North, Quantum, UK, Doyle, Ullman, etc) all center on the relative merits of flying a "1/2 pole" or "full pole". Chicago-Mackinac experience shows that J/111s with the Code Zero mounted on the end of the fully extended sprit are faster than those who have tried "1/2 pole". 8 hours under C-0 conditions more than proved that point with about a dozen boats!

    That is the basic idea. The issue with current C40 designs is that they are too wide (lots of wetted surface), too big a rig (start reefing in 17 kts TWS upwind), too much water and too deep on the keel. No question, 17+ TWS from 110 to 165 TWA they will be quicker. However, upwind in breeze or lighter conditions, the 1-2-1 should give away very little in terms of relative performance.

    To answer the question about water ballast for a number of you, the basic idea is to reduce the number of crew needed to sail offshore or around the buoys. 100 US gallon tanks on each side represent about 800 lbs or 5 average size crew members. The target is about a 45 second "dump" from one tank to another using 6" pipe. So, for most Solent racing scenarios, that's more than enough time to move the water (BTW, that's over 3x faster than current designs in Class 40s). Offshore, of course, that's more than enough time, even using the electric water pump which will use one central intake. The use of water ballast systems has been widely used for well over two decades. The systems have been refined for IMOCA 60 and Maxi 100 ft canting keelers. It's cheap, efficient, and works well compared to either (a) lots of crew or ( canting keels. The J design team consulted with the best in the business, including engineers that have done work for IMOCA 60s, Class 40s, and the 100 ft Comanche. The discussion regards ratings is a bit premature at the moment. On-going dialogue with various rating groups is focused on encouraging better sailing, easier to handle boats. For example, PHRF, ORC and IRC would permit up to 12 persons to sail on a 40-41 ft boat- which is absurd from a logistics standpoint. There is no question, the economy and logistics weigh heavily on many owner's sailing schedules- it's no wonder short-handed events continue to grow in popularity. Design considerations? The hull is aimed at sailing fast offshore, optimized to the basic parameters of 15% beat/ 65% reach/ 20% run. As a result, it's beamier relative to the J/111 and far more "powerful" in terms of righting moment. The 1-2-1 will be quick reaching, without sacrificing uphill VMG. The key "horsepower" ratios of SA/DSPL and SA/WS are closer to the famous J/125 than the J/111- with much longer relative luff-lengths on main, gennakers and Codes (Zero and CodeBlade)- that will give you an idea of offwind potential. Relative speeds? The J/111 today can sail faster around the track than existing Class 40s designs in anything under 8 kts TWS. That has been proven in Fastnets, Bermuda and the recent Middle Sea Race. The 1-2-1 is 4 ft longer on SWL and can fit into the Class 40 rules, which means owners may be able to expand their sailing horizons and fit in as a "sub-class". Ease of sailing? The target is to have at least one halyard winch electric standard, with the option to have both primary winches electric (that is a safety consideration as well since it makes it easier to "pull" a person up the rig for double-handed sailors). That feature, plus providing auto-pilots will greatly simplify boat-handling for 1-2-1 class racing around the cans and offshore.

    J/88's at Key West had a lot of fun. Just ask Sandy Butler! BTW, who should be a SCOTW! Here's what happened: The J/88 class was decided on Friday with Rob & Sandy Butler sailing TOUCH2PLAY RACING to victory in both races. That clutch performance gave the Canadian entry the same amount of points as DEVIATION, skippered by Iris Vogel of New Rochelle, New York. TOUCH2PLAY won the tiebreaker by virtue of more first place finishes. "We put the pressure on (Deviation) by winning the last race on Thursday. We still trailed by two points so we knew we had to come out and win both races today," Rob Butler said. "Our crew was really dialed in and we had very good boat speed. I'm proud of the team for doing what we had to do in order to win the regatta." Behind these two, it was David Betts’ INSTANT KARMA that took third, narrowly beating out Joe & Jeff Pawlowski’s EASY EIGHTS in fourth and Chester Kolascz’s SARALYSIA in fifth.

    J/111 Goes Sailing...

    Shape is more important than size when it comes to staysails. It's very easy to choke the flow behind the main (so sprit lenght isn't really the issue). There's been a lot of research done in the TP52 class, and they use staysails as soon as the conditions allows. If the wind is up they loose to much speed having people up front (at least on a short course) so then they keep their jibs up but the better teams goes to staysail asap when possible. We're extremely happy with our staysail (below) and wanted North to make a bigger one. They basically refused to make it bigger... Not that often a sailmaker turns down a sale Next time, tell them to make it TWICE as big, tack it to the stemhead fitting and raise clew high enough to trim from 2/3 back on main boom. Sailmakers are their own worst enemy! We did this on the J/41 and kicked the shit out of anybody who had anything less-- just ask Bill Shore and Kenny Read when we raced the J/41 DAZZLER back in the IOR days. Sprit boats/ asym boats react even BETTER to a properly design staysail. The clowns at the various sail lofts have not figured out how to do these things better-- have no idea what "fashion" they're following today-- as usual, they're wrong. After all, WHY did the AC33 boats in Valencia have HUGE staysails and tried to fly them at ANY time?!!!! Doh!

    J/111 Goes Sailing...

    Interesting to see points of view on staysail/ spaysail and jibs on sprit boats. TP52s have a "short' sprit; so, stay/spaysails are critical in terms of dimension/ trim. On the J/111, with an 8 foot pole, less so. The jib is KEY for faster downwind speed in the absence of any staysail. A MONSTER spay/staysail is simply a "gift". Under ANY rule on the J/111. Anytime you add this "flow control" sail under the a-sail/ main it adds from 1/4 to 3/4 knots, easy. If not higher. The J/111 is an apparent wind machine and does respond to added "flow control" between the main/chute.
