Nothing anyone has said here addresses these factors.
As for Garmin, how often do any of you, other than Mark, travel far enough that you would require more than a few of Garmin's proprietary charts chips? I use one for Bermuda, one for the eastern Caribbean and one for the western Caribbean. Big deal; 3 chips! Even if one was sailing from the PNW to New England, only 4 or maybe 5 chips would be necessary, considering all US waters (even Ak & Hawaii) are preloaded into all Garmin chartplotters.
That certainly wouldn't (hasn't!) put me off buying a Garmin GPS chartplotter that has given me excellent, reliable and consistently accurate service for over 14 years now, with the last 12 sitting in a pod 24/7/365 at the pedestal, exposed to rain, sun and humidity. It is handy to the helm, easily reached to change screens, view the radar, weather (if in range of SiriusXM Marine Weather), always plugged in and never needs charging, easily read in daylight or dark, 100% waterproof.
And, if one is stuck on the helm for an extended time steering through some heavy weather near shore, what would you folks touting the computer/tablet route use for navigation once your battery has worn down, given that the computer/tablet you are using has survived the several waves that most likely have engulfed the cockpit in those conditions?
Gotta laugh...I had a Toughbook cf52 that did not make it 100 miles last year. A wave in Abelmarle Sound managed to slosh over the windward rail and immediately shorted the thing out. The CF52 is billed as "semi rugged:-) The fully rugged Toughbooks are much more able to survive a boat but I agree, none of them are nearly as good as a good chartplotter and they are power hogs.

Do you hand steer or use a AP or vane? Itís no issue in the middle of the passage but usually fix with a pin so windvane is off and use the AP for the first day and last day of passage.
Charts usually arenít the issue mid ocean but only at the hard edges. Hand steering gets old fast even with a big crew.
Have not been offshore much in the last few years, so have not needed it but I get NOAA Weatherfax over SSB/Pactor/Computer. It's a bit cumbersome but has worked quite well.

Polar Navy's PolarView NS was $30 for 5 (perpetual) licenses when it came out. Then it jumped to $50 for 5 licenses. Last June I paid $70 for 1 (perpetual) license which included a $20/year chart update subscription.

Re: Charts and Chartplotters

For inshore and coastal sailing Iíve found Navionics on the phone in a holder at the helm and OpenCpn on the laptop down below is all thatís needed. Separate depth instrument at the helm station.

Simple, inexpensive, have all the info I need.

No Radar or AIS?

Re: Charts and Chartplotters

No sir.....havenít needed either for the sailing Iíve done in Florida, Keys, Bahamas....can see where both would be convenient to have, but not necessities.

Re: Charts and Chartplotters

Did I respond to this thread? If I did... sorry to do it again.

Our Ray C80 is below decks and it displays radar and AIS etc. Not a great location for single and shorthanded sailing. I have an ancient Standard CP170 down below which I don't bother to turn on... waste amps

We have 7 cockpit dash displays...

Fluxgate compass w/GPS data (XTE, CTW....) connected to C80 (NMEA 183)
Depth
GPS data - XTE, SOG, COG, DTW, CTW, TTG ...+ connected to C80 (NMEA 183)
Boat Speed (#.##)
Race Repeater - VMG, true wind speed, true wind angle ...+
Analog Apparent wind dial
Apparent wind speed.

I have a B&G Zeus T7 under dodger winch mounted

If I have the smartphone in the cockpit... it sits on the coach roof (charging) I may run navionics for a second "chart view"

I do not helm the boat manually except to and from a mooring or to drop the anchor... and on and off the fuel or town dock. All other steering is done by an AP with its control head forward in the cockpit and I set the course with a rotary dial.

++++

N2K Upgrade:

T7 moves down below.
New Zeus3-9 assumes the winch mount location on network
4 dash mounted Triton 2
Vesper AIS B
New masthead AWI
New radar scanner
New External GPS antenna
existing speed, depth, temp transducer

Upgrade will be to N2k

pay attention... someone's life depends on it

I can update my Navionics easily by downloading the update from the website.

Re: Charts and Chartplotters

This updating charts scares me and makes me think things are changing so much I will get into trouble without the latex charts.

Or is added "features/software"?

Don't quite understand the plotter/tablet tie-in to weather, unless you are just mentioning it as a separate topic. Satphone email and SSB/Pactor files are easy to use on tablets and computers. In fact, with a SSB or even a receiver, you can use tablet apps to get weather files through their microphone inputs.

Our radar is at the helm because it is also the plotter display - and I prefer it there - but if I was honest about it, there really isn't much reason for radar to be at the helm. Even using ARPA doesn't generally require immediate and constant attention to the display.

If you do end up getting a new plotter, most of them now connect wirelessly to tablets, which give you viewing and control of the plotter wherever you have your tablet with you.

Installing a NMEA wifi converter will give you all your instrument and AIS data wirelessly to phone/tablet/computer. They aren't too expensive, and with a phone in your pocket, you could stay connected to the boat data while off helm/watch.
