    Arete' tri going for Chicago to Mac record

    https://photos.app.goo.gl/qpXxj7m4R8TfDyjH7 From the top of Sleeping Bear Point. It's hard to spot, but the boat is roughly in the middle. I don't own a fancy camera with a big zoom lens. Will try to post some better pictures later.

    Negative. Looks to be about 22kts since the start.

    B&G H2000 Backlight Problem w/ Expedition

    Thanks, the terminators appear to be correct. I forgot to post back with an update - it turns out I was loading up the H3000 with too much external data. I talked to our B&G guy, who explained that while the H2000 system received an update to process tags from external sources, the H3000 never did. Support was discontinued in favor of H5000. Anyway, I cut back on the Expedition data displayed, and the problems with freezing and lights cutting out went away. I haven't had time to experiment with turning off the "send tags" option.

    B&G H2000 Backlight Problem w/ Expedition

    Aside from the computer, the only device connected to the B&G is the Garmin GPSMap chartplotter. The Nport is connected to the B&G performance processor with a serial cable. This is wired to a wifi router with an ethernet cable. The Garmin is connected through one of it's NMEA ports through the second serial port on the Moxa. RTS/CTS seems to be working properly. Each device is treated by the PC as it's own COM port over wifi, using Moxa drivers. The Fastnet system seems fine, and everything works when the computer is not connected. There are two terminators. The H2000 system has the latest firmware, but I am not sure if the H3000 GFD has had any updates. This seems like a problem with data overload, particularly with the H3000 display being used on an older system. I can't confirm, but I have a feeling the lights are shutting off at the moment the H3000 GFD freezes. I will turn off tags and reduce Expedition channels when I get back to the boat. I probably cannot borrow another display or update this one before the race. Thanks for the insight!
  5. Throughout the off-season, I worked to install a computer running Expedition on a boat with a slightly cobbled B&G H2000 system. Everything has been working, until we noticed a few problems during the delivery to Port Huron. The boat has an H2000 processor and performance processor, with a wireless connection to the computer via a Moxa Nport serial to ethernet converter. The displays are 4 x 20/20's, 2 x H2000 NMEA FFD, and one H3000 GFD. The H3000 display has been freezing when receiving waypoint data and targets from Expedition. It has always frozen occasionally while receiving waypoint data from the Garmin chartplotter. The more recent problem is that the instrument backlight shuts off at random intervals, and must be turned back on by pressing one of the power/light buttons. Sometimes it shuts off after a minute, and sometimes up to an hour. Of course, this is bound to happen in the worst conditions during the race. Has anyone experienced any of this? I kept the computer after getting off at the first stop, and it sounds like they had no more trouble with the freezing or lights while Expedition was not connected.

    PredictWind vs Sail Flow vs Whoever - The sequel

    I can say that last year during the Mackinac races, ECMWF consistently forecasted a bit higher wind speed than actual. This is also consistent with local experience lately. It may have something to do with how the ECMWF model averages gusts, compared to GFS/NWS. I have not used Windy, but I have heard they use ECMWF. On the same topic, has anyone been paying attention to GRIB accuracy in the Great Lakes? Seems like the GFS has been off by several hours either way for the last couple of weeks.

    It's knot a boat, but a local restaurant is called

    Sweet, good luck! I'm on Relentless, the Schock 40 up north.

    Got ours today, too. 1.038 AP and 1.046 OW. Looks like we're all in the Section 02 club?

    Musto Vs Zhik

    I have had Zhik Aroshell salopettes for three years now. They have held up well and are plenty waterproof. I wish the ankles had some neoprene or something in the cuff, but the big velcro closure stays put. I mostly bought them for the size, as I am 6'3" and 180lbs. Many of the other companies require an XXL for my leg length, with a gargantuan chest size.

    PredictWind vs Sail Flow vs Whoever - The sequel

    This is my opinion of almost all bouy racing locations, as we tend to race in protected waters. The basic idea is that hot air rises over land, because the hot sun warms up dirt or concrete or whatever. This rising air disrupts the pressure gradient wind. Because the pressure gradient is different every day, the effect of disruption will also differ. Predict Wind claims their algorithm accounts for land influence, but the size of our bouy courses are too small for a world-wide algorithm to figure out. Check out Wind Strategy by David Houghton. It's a short book with lots of illustrations, and the rules described seem pretty accurate.

    PredictWind vs Sail Flow vs Whoever - The sequel

    I used Predict Wind on the Great Lakes last summer, and was not particularly impressed. The PW models almost always understated the wind speed. The ECMWF model overstated regularly, and the timing was out of sync. The GFS model seems to be the most accurate for my region, and is available for free from several sources. To answer your question, no weather forecast will be accurate enough to win you a buoy race. I have not sailed in Narragansett Bay, but I would guess that the influence of surrounding land is going to make a larger difference on what wind you experience than any major pressure system changes within the hour or two you are racing. For something like a Wednesday night buoy race, I usually look at the chart attached in the morning. Then check your favorite weather station all day, and note changes. If you have an all-day Saturday race, then watching a GRIB can be helpful for being aware those changes are coming - but only for the big picture. As far as which one is most accurate - watch and compare regularly for days or weeks.

    Is this from personal observation, or is there a source that regularly compares gribs to reality?

    B&G to Expedition

    I am working to set up a similar package as we speak. I should know more this week, after the boat is in the water. I am planning to use rs232 into a serial to WiFi access point. From what I understand so far, you want to use rs232 and not nmea 0183. This way, you can show all of the fancy Expedition calculations on the b&g displays.
