    Jeanne Socrates - nonstop solo RTW 2018

    Yes, the unnamed targets are from sat reception, unless you are paying big bucks to have full sat-ais reporting. I'm paying about $6 a month to have Marinetraffic.com show me Jeanne's AIS reports when a satellite picks them up (you can pay for one vessel, more vessels, or all). It's actually been a couple of weeks since her previous sat reception, but one came in last night:

    Here is her reply: I've found some sea ice charts and South Africa marine WX, and sent her the links. I also found an old schedule for Cape Naval WFAX, and sent her the text (same data as in the big NOAA worldwide WFAX schedule). Can anyone find good sources for this stuff? The ones I found were really too large (in kBytes) for her to use regularly.

    Those are good links! I'm not in regular contact, but I can send her email via SSB WInlink (I don't have her satphone #). I will send her a short list of the synoptic chart URLs, and she should be able to request the image files via saildocs. I assume that she has the NOAA "Big list of worldwide WFAX transmissions", but will offer to send her that as well.

    Nov 4, 20:22 UTC -- Jeanne has crossed the equator! She's currently sailing almost due south, at 5.8 kts. And she's making some progress on her electrical problems. Way to go, Jeanne!

    Equipment issues: Neither solar panel is providing any juice. In a way that's a good thing, since it tells me that it's a wiring problem. Having both panels fail so close together is quite unlikely. (And she has mentioned green butt connections). I hope she's got enough spare wire, connectors, etc.

    OK, what could she have done better, given the boat she's got and the resources available to her? Here's my list: She could have installed a stronger windvane, such as a Monitor. Her aux-rudder Windpilot doesn't have the power to keep her on-course when conditions abruptly change, so she finds herself hove-to on the wrong tack. This will be less of an issue when she gets to strong and steady winds. And regarding the off-course issue, she should have a loud off-course and/or wind angle alarm. She should have been more thorough when inspecting her rigging before she cast off. Her solar panel problems are self-inflicted. There's no reason that the wiring and connections should be failing so soon. She probably could have found a better day to start, even given the season/schedule constraints of her RTW voyage. A few days plus or minus could have made a big difference at the beginning. Gosh, isn't hindsight great, especially from the comfort of my La-Z-Boy recliner? And honestly, I've always got a similar list after any of my big passages, so no disrespect intended.

    To be sure. There's a reason that the RTW speed records are set by multihulls. But the boat has to be matched to the crew. I don't think putting Jeanne (or me) on a 100-ft trimaran would work very well, although it did for Gabart.

    So you're saying that two guys sailing a proa from Half Moon Bay to the Marquesas in June were faster than Jeanne on her singlehanded route from Victoria towards Cape Horn in a displacement monohull during October? Yep, she's slower, but I'm not sure that's the point of her voyage. What I'm curious to see is how she gets through the southern trades and horse latitudes. There is a somewhat persistent high near 130W/35S, but it does get shoved around by the lows as they move east. Will she stay to the west of that, or try to find a route in front of one of the lows? (remember, lows spin clockwise south of the equator) Those lows move fast though, and it looks like she would be facing adverse winds more often than not if she tries to thread that needle.

    The rhumb line is what you get when you plot a straight line on a Mercator projection chart (a typical marine chart or map). As you note, this gives you a constant compass bearing. A great circle route is the result if you stretch a string from one point to another on a spherical globe. It's usually shorter than the matching rhumb line (if the direction exactly is north/south or east/west, the two lines are identical.) Jeanne still has some patches of light air ahead, but yes, it looks like she's through the worst of that now. She will sail SE when she has to, but I suspect that she will be trying to make it due south when she can for the next 1000 miles or so, given the average wind directions. Check out the windy.com GRIB display for the next nine days: There is a persistent south-pacific high around 35S / 130W that she has to get around. If it's anything like the NPAC High (and I assume it is), she's going to want to sail around the western edge of that. While you're looking at the forecast, watch the low-pressure systems marching from west to east at around 50S. In some areas the waves are 32 ft @ 13 seconds. It's all pretty hairy. Of course Jeanne is currently about 2,500 miles north of that spot.

    Here's the wind in 24 hours. Even though the "Maxwell's Daemon" strategy of maximizing the microscopic gains and minimizing the microscopic losses during random light-air conditions is probably her best bet, this is hard on the boat. During my Pacific Cup races, many of the fleet's gear failures were caused by slatting about in no wind and confused seas. We always tried to get somewhere else, but if she can just sit it out and wait for favorable winds it might be prudent to button things up so there's less shock-loading on the rigging. But that's uncomfortable too, and having sail up will reduce the rolling...

    So she sailed in whatever direction she could for nearly two days, then was able to head south-ish for a day, gaining about 60 miles. But now a much larger dead zone has moved on top of Nereida. It's going to be another few frustrating days.

    Wait long enough and the wind will find you. Still waiting...

    You said this: So we assumed this related to whatever point you were trying to make.

    So it's kind of like San Francisco's "Three Bridge Fiasco" race? 300+/- sailboats.
