  1. Spent some time looking at the B&G manuals. The bad news: - The H5000 Graphic Display doesn’t seem to have a WhatIf? function (which is a Zeus-only app), so you’re not going to get an identical view as on the Zeus. - The H5000 Graphic Display has a Layline view but that is not detailed in the H5000 manual, so it may (or not) provide you the data you want. You can also create a custom view (eg 2x2 grid) and display next leg AWS/AWA. But all these functions are tagged as Hercules+, so if you only have the baseline H5000 then you need the paid software upgrade… The reason seems t
  2. For 4 numbers another option would be one B&G H5000 graphic display in 2x2 grid mode, as shown on the mast here: https://www.bandg.com/en-gb/blog/calibrating-an-h5000-instrument-system/ But that’s about the same price as 2x Triton and probably less readable/flexible overall. The H5000 graphic display only has a 5” screen so a lot less screen real estate than 2x 4.1” Triton 2s, though the rectangular screen is a little more space efficient. No idea on NASA, never seemed very popular or modern (still NMEA 0183).
  3. Good older thread here (2017) - lots of discussion. Note: Racegeek went out of business, so not an option. Also this thread on B&G Nemesis (not an option for most people due to eye-watering pricing by B&G): https://forums.sailinganarchy.com/index.php?/topic/218276-bg-nemesis/
  4. Depends what are you trying to do, what information you want on the mast, budget and how much you care about custom fields (eg polar data). Below are a bunch of mast-compatible options. General NMEA 2000 repeaters: - Garmin GNX 120 is a popular 7” repeater nowadays. Displays 1 large and 2 small data fields. Will not usually display proprietary non-Garmin fields (eg B&G H5000 polar-related fields) unless you go through a laptop running Expedition or similar to convert the proprietary fields to custom N2K fields. - B&G 20/20 HV displays 1 large field. - Sai
  5. Great to hear first hand experience. Impressive boat speed too… I’m curious, how do you decide which angle to set? For example for TWA downwind, does the autopilot just take whatever TWA you’re at when you engage the TWA mode (and then you adjust it manually, same as in heading mode)? Or are there some more “smarts” and self-adjustments by the autopilot?
  6. Right, starting to sound like a B&G firmware issue. A bit surprising for something as basic as a knotmeter, unless you’re talking esoteric sensors, not plain-vanilla Airmar paddlewheels…. I would hope any knotmeter connectivity issues get caught early in B&G QA bench tests… Keep us posted, I’m curious what you find.
  7. So your sensor has been tested on two H5000 CPUs and did not register each time… Sounds like a dud sensor - I would ask the supplier to send a new sensor. Either that or it is a more systematic compatibility issue or B&G H5000 firmware issue…. (Or a settings issue on both H5000s, but that seems unlikely with certified installers). As WHK said, it would really help to know the sensor brand & model number (plus a picture of the sensor’s label itself).
  8. I think this happens to be both true and false. Depends on what you mean by TWA… - Basic TWA (steer to fixed TWA = X deg set by user): NAC-3 should be able to do this (as can even older Raymarine units I have more experience with). This is cruising level TWA piloting. The support is clearly specified in the manual, and user “Rabbi” describes using a NAC-3 on a Lagoon 38 in auto AWA/TWA mode here: https://www.cruisersforum.com/forums/f48/b-and-g-autopilots-195586.html - Polar TWA (steer to computed optimum TWA given TWS and target waypoint): this is an advanced 4th mode specified in H
  9. Under B&G Downloads/Manuals, look at the Commissioning Manual. Looks like it works with TWA and AWA, though few details on specifics. If you have a rotating mast, TWA likely will be meaningless anyways unless you have another way to compensate rotation (or have a H5000…). ”Wind mode: Select what wind angle the autopilot will steer towards. The following options are available: • Auto If True Wind Angle (TWA) is <70: Wind mode will steer towards Apparant Wind Angle (AWA) If TWA is ≥70: Wind mode will steer towards TWA • Apparent: Steers towards AWA • True: Steers
  10. Good idea - hadn’t seen one of those before. Maybe a bit challenging to recharge in a wet environment like a beach cat, but would work in calmer days or in a cabin. I like the idea of this for routine charging of handheld VHF/GPS plus a separate AAA battery tray for true emergencies. Back to OP - nothing wrong with HX870 in my personal experience. I would buy it again, or the HX890. ICOM reputation is always a bit better but Standard Horizon pricing is good value. (Note: in my prior posts I wrote HX890 but actually my experience was with the prior gen model, HX870. Too late to
  11. I think it depends on the use case. I chose the SH HX890 for R2AK 2017, specifically because of the battery tray (we were on a beach cat with no onboard charging source). Our trip was 7.5 days, and we ended up going ashore long enough to recharge the standard battery only twice. I used the standard battery whenever possible, while keeping a battery tray in my pfd for emergencies. Of course I didn't keep the VHF on full-time, only turned it on periodically when I wanted to check weather channels, or sometimes at night -- so the number of hours of use was not high. Still, I felt much happier
  12. +1 for F18's wrist suggestion. For R2AK 2017 on a Nacra Inter 20, a Garmin GPSMap 78 practically lived on my wrist for 7 days. Very convenient, out of sight when you don't need it, while still only a glance away. No mobility issues even when going for a swim (capsizing). That plus Navionics on a smartphone in a neck pouch tucked under the pfd (much easier for route planning/strategy than the small-screen of the 78). Both of us onboard had the same electronics setup for redundancy in case of breakage or if one of us went overboard... See starting 2:15 here: https://youtu.be/YTWp4D
  13. What’s your program? Racing, cruising, a bit of both? In the Bay Area most boats that race are the F-31R rotating+extended mast version with transum hung rudders, rating -15 to +10 on PHRF. Fun boats to sail. Interiors vary a lot, as do boat weights. You probably want the R variants since you are in a light airs area. F-9 / F-9R is homebuilt / kit version of the F-31R, as far as I know. But i’m no expert - there are good specs / materials online if you google. F-31-1D is the turbocharged version of the F-31R with a bigger mast, significantly faster (about -35 PHRF if I rem
  14. The Ad says a "Banks 35". Not sure which one -- looks like a newer build (ad says 1989) of a 1970s design. Were popular up in PNW if you look at this site: http://bcmultihulls.blogspot.com/ (Banks 35 are: Limelight V, Solar Heat) Folks up in PNW may be able to tell us more. To me it looks like a longer version of a Stilleto -- light but pretty low on the water.
  15. Good deal ($80K) on a F-25C up in Seattle with basically brand new sails: https://seattle.craigslist.org/see/boa/d/farrier-25c-race-trimaran/6496222856.html. A bit too high for my budget, but I suspect this is going to make one multihull sailor mighty happy... In the meantime, less than 48H left on bidding Hurts Like Heaven, an even better deal (I suspect): https://www.trademe.co.nz/Browse/Listing.aspx?id=1546764972. TradeMe is limited to residents of NZ or AUS, so I figure I'm going to be watching this one from afar -- otherwise I'd be sinking my teeth in with a decent offer...!
