![]() ![]() The competition hated when the blue A5 came up. It should be a weapon at TWA 120-130 when we had a blast in the 109. It’s narrow and have more twist, but still relatively powerful. This sail is a development of the A5 we used on the 109. Will be exciting…Īsymmetric spinnaker A5 Supercote 130-90 aka “The Reacher” Hoefully we’re able to carry it up to 24 knots before changing down to a smaller kite. We figure that the A2 will work in TWA 130-150 in light conditions up to 140-170 when the wind picks up. The same sail in one design size on J-Dream, one of the faster boats in the UK fleet. On the 109 we didn’t need it since the A2 was a pure runner. When going low it’s easy to get to much twist. Naturally the design becomes a compromise since it should work in both “modes”. The 111 doesn’t have much stability so it’s important to find the right balance. ![]() High enough to generate power, low enough to sail flat. In more wind the boat will plane, and we usually end up with TWA 140-150. Then we want the sail to rotate to windward so we release the tack and hike the boat to help the sail. ![]() On the J/111 we go low at displacement speed between 4 and 16 knots of wind. When we switched to North and the latest generation of pure runners for the 109, it was super fast on the run but choked at tighter angles. On the 109 we started out with a Quantum design that was very versatile and fast in many conditions, TWA 125-160. Also, with 157 m² nylon, we’ll get some exciting downwind runs throughout the register :-)Īn A2 can come in many shapes. If we get it going in our normal see breeze conditions, that would pay dividends. One reason is to get more power in the light stuff, another is that we want to lower the treshold where the boat planes. The one design runner for J/111 is ~130 m² but we’ve chosen to make it bigger. All photos from our sail tests in Långedrag taken by Olof Stenlund.Īsymmetric spinnaker A2 Superkote 80-60 aka “The Whomper” What works and what doesn’t? Sweet spots and blind spots? With limited time, we’ve identified a short list of questions that’s important right now: primarily cross overs for the code 0 as well as target speeds and VMG downwind. ![]() Now we have started the endless task of verifying and adjusting the chart. With fewer sails it’s even more important to get this right. Sail selection is always a balance between being around, without weak spots, or having rally fast sails for some special conditions. Thanks to Anders Lewander from North Sails who helped map the sails to TWA and TWS. Here’s the first version of our Sail Selection Chart. The difference with the J/111 is that it builds apparent wind much faster, that we need to get it on a plane as soon as possible and that we might miss the genoa in certain conditions offshore or going around islands. The A5 also doubled as a heavy weather chute, especially shorthanded. Naturally we brought a lot of the thinking from the J/109, where we’ve done great with the class A2 runner in TWA 135-170 and a smaller and flatter A5 reacher in 100-135. Naturally we would pay with a higher rating, but we were prepared to do that and didn’t want to optimize for any rule. Also we wanted the boat to be really fast in light air, when many of our races are decided. The crazy downwind rides are the ones you remember after the season, and we wanted more of those. One goal with the J/111 is to get as much fun downwind sailing as possible. When it comes to the downwind inventory our philosophy is slightly different. In an earlier article on upwind sails, I focused on our inventory that was basically one-design. This is an English version of this article.

Also, the cable spins faster than the sail during furling which means the latter sometimes jams. Problem: Because asymmetric spinnaker cloth is both light and fragile, the anti-twist cable has a tendency to damage it. SAIL BEARING TECHNOLOGY: EFFICIENT, RELIABLE FURLING ![]()
