The problem is not that say, eBay, reads that: they created it to track some things for their own purposes. The problem is that any of us can read that, and more to the point when we use the link the site uses that data whether appropriate or not. So putting it out there on a public forum is not always the best idea.

Right on, I appreciate your thoughtfulness Greg. One thing about it, the Sailing Community is full of great and knowledgeable people which to McGee is a blessing. Thank you!

I have decent basic outdated Signet nav instruments in the cockpit; wind direction, speed, knot log, compass, depth sounder and it all works pretty well.

I have one outdated local paper chart and wonder if I could print charts from OpenCPN...
I used my Toshiba Satellite Laptop to test OpenCPN 5.0 (and 5.2) with a GPS Puck and it worked great.

I use the same puck with my Raspberry Pi.

The "little boat" shows up on the chart at my apartment using the Toshiba since it's very close to the water. Perfect for testing the computers before taking them to the boat.

Re: Chart plotter, gps, sonar suggestions

The Garmin 5212 chart plotter and GPS antenna are available from my friend if anyone is interested. This large display unit is overkill for the skipper's 25' boat. It would be wonderful for a bigger boat, especially one with a wheel and helm. I have mine interfaced with an AIS VHF and now with Raymarine instruments via NMEA 2000. Get back to me if interested.

Re: Chart plotter, gps, sonar suggestions

Just a thought: Consider a cheap/used fish finder GPS/depth sounder - where the transducer mounts externally on the transom. These can be lifted/tilted out of the water to prevent weed growth when not required and obviously doesn’t require yet another hole drilled in the hull

Re: Chart plotter, gps, sonar suggestions

I bought a under $100 Android tablet on Amazon, and AquaMaps US for $18 - Lifetime subscription covers all US and Canada. I can expand that incrementally, I just made sure the tablet had integrated true GPS receiver, not dependent on wi-fi or cell networks.

I was looking at the Garmin handhelds that float but I really need something that's going to give me good chart access and the information I need to stay out of trouble. I'm not sure the handheld has all that and I'm not proud but I don't want to make "that" call in any case. I just want to go about my way safely as possible and not get too lost.

Thank you, come again please. D:

You had me at ducketts - consider also sovereigns, guineas, schillings, rupees, ducats, dinars, yuan and talents.
Have to admire the man with a 25 footer and a thirst for circumnavigation with a $200 nav budget. But what MOST pleases me in this terrain of the 40 ft cruisers is the pleasant, helpful responses he obtained. Good on ya!

Re: Chart plotter, gps, sonar suggestions

For a good chartplotter option on a serious budget, I don't think you can do better than a decent used iPad in a waterproof case, and the free software OpenCpn. All the charts in the US are available for free download from NOAA.
OpenCpn will also show you an "instrument" showing depth, speed, wind, etc, etc. if you have that data from sensors.
The rest of the features on a dedicated chartplotter are "nice to haves" and not really worth spending hundreds to thousands to get.

You will find this setup on a number of the serious rond-the-world cruisers, like s/v Delos for instance.

Re: Chart plotter, gps, sonar suggestions

+1 on all the comments below.
So you want to circumnavigate with a McGregor 25 and a $200 budget for nav gear? if there is a small Island near you, say up to 3 miles long, it can be a good place to start practicing.

Good luck

Most smartphones have gps inside, so if you want a 'plotter' simply set it up with a chart of your area and that's that.


If there are many booby traps where you sail, do get a depth sounder though. And then stay in deep water. Rocks, shoals and other such are best watched from a long mile.


I like handhelds. I can keep one in the pocket, no need to fix it anywhere. I can check what the boat is doing also from my bunk then.

Re: Chart plotter, gps, sonar suggestions

I would try and get a older iPad that has no gps. Sync it with a Bad Elf which gives the iPad gps. Then use something like Navionics. You end up with a good size plotter. Always have a back up like a small Garmin gps that gives lat Lon. And some paper charts always. You want it to be fun, not a suicide mission.

Re: Chart plotter, gps, sonar suggestions

Smart phones require either a cell signal or WiFi to engage their gps.

Not if you're using an app that stores the maps and other data it needs locally on the phone. Any semi-modern smartphone has a full GPS receiver in it that doesn't rely on external networks to function.

External to gps.


Gps is an external network already.


Just sayin'
