  1. On H5 there are three derived variables that kinda do this: Average True Wind Direction, Wind Lift and Wind Phase. Wind lift shows + for a lift on each tack Wind phase shows difference from mean regardless of tack (i.e. positive is left)
  2. Easiest thing to do is to get the ip address from a graphic display or a zeus2/3 vulcan5/7/9 On the H5000 graphic display its Settings->System->Network->CPU Info On the Zeus/Vulcan its Home->H5000->CPU Info I know you said the whole IT thing is not your strong point, but do you know if there is something on your network that is acting as the DHCP server (the thing that hands out IP addresses) this is usually a router?
  3. Haha these helpful suggestions were even better than I anticipated!
  4. Has anyone got an suggestions on what material to use to line a cradle for a dry-sailed 40 foot IRC boat. We had some issues last year with the hull getting marked, I guess because the moisture was not draining well from the cradle.
  5. The brightness is ok... I agree not the best, but I spend most of my time on the south coast of the UK so not so much of an issue!! Here are the full list of touchscreen options. I didn't buy the B2 stylus because the wet mode for touch seems plenty good enough. The stylus would be good for using expedition over RDP where the buttons are a little too small. I am slightly confused because the stylus listed here: is listed as capacitive rather than some other tech that won't be affected by water Anyway... the Touch (water) setting seems to be a million times better than standard pen and touch
  6. Others will have found this before me, but I can't believe I hadn't so I thought I would share... Last season I started to use a panasonic toughpad FZ-B2 as a deck tablet to repeat either the b&g zeus2 or a windows machine running expedition below. It's a great little device. It has a solid feel and is the perfect size for me despite sounding a bit small on paper. The one downside to it has been that it suffers really badly from false water touches and can suddenly become totally unusable even when the screen has been locked and wiped dry. However this morning I was searching to see whether there was a digitizer available for this model when I found a menu in the android device settings Settings -> Display -> Touchscreen Mode -> Touch (Water) On changing to this setting the screen is amazingly responsive even when covered with water droplets. I can't believe I did a whole season before finding this!
  7. What is it? ZG100? I wouldn't worry. As said above GPS speed is Doppler calculated and is hard to get right stopped. Will be more accurate when you're moving.
  8. You can put some dedicated instrument pages on the vulcan 5. For me the main issue with using the vulcan family in a system with other MFDs is that because it doesn't have ethernet it can't share charts it won't seamlessly start navigating to the same waypoint as the Zeus (I don't think this has been worked around yet but happy to be corrected) As long as you are aware of these issues the vulcan 5 is a cute little display.
  9. So if you don't have H3/5000 you don't want to choose polar. If you have latest software you should have an option called targets table (or similar, I can't remember) The polar option is only if you have an H5000 cpu on the network that manages your polars and other advanced features.
  10. You can configure the targets under settings -> chart settings -> sailsteer The tide corrected lay lines on the chart would previously just use current boat speed and either current twa or a simple upwind/downind target angle for all speeds. Now there is a lookup table which will adjust your laylines for the given wind strength using the targets from the tables. This already happened if you had an H3000/H5000 connected and had target wind angles set to polar, but it is a nice trickle down from the higher end packages.
  11. No. And why on earth would you want to? Buy a $100 windows tablet.
  12. Opencpn is written in c++ using the wx widget framework and can be built for pretty much any platform that you can get a c++ compiler for... windows, linux, macOs, android. Apples iOS operating system is really tightly locked down and app development is completely differrent. You would basically be asking them to start from scratch. If you want open cpn on a tablet, buy a windows tablet.
  13. I think the version I mentioned gets called Zeus 2 4.0
  14. Doesn't latest software (NOS55 and above) give you basic start line, what if page and target speed/angle tables without an H5000 system? Amazingly they don't do a great job of publicising when these new features get added to released products!! These should be present in Zeus2, Vulcan and Zeus3
  15. I think the display is much brighter and higher resolution, More physical buttons is a big bonus for me. I always felt it was tough to operate the z2 with just the rotary knob.
