It can go toe-to-toe with a sophisticated chartplotter, and if you keep it below at the nav station, it is an excellent backup and repeat station.

Even at the high price, it is so much cheaper than stand-alone chartplotters that you can cover a good part of the cost of a MacMini or MacBook Air and get a sophisticated computer in the bargain. PolarView PolarView is the most recent entry into computer chartplotting software for the Mac. It is produced by the Florida company Polar Navy, which like the MacEnc company, is pretty much a one-person operation.

An email to Polar Navy will get a very rapid response from the programmer, Gene Antsilevich. You can download a day trial version that has most functions; paying the purchase price will get you a code that activates all functions. The versions operate virtually identically. One peculiarity is that you have to download a second program for free called PolarCOM and open it when you open PolarView.

It connects the GPS to the program, which otherwise would work only as a chart viewer and planner. Another feature not available on the other Mac programs we tested is the inclusion of Active Captain info. Once you subscribe to Active Captain free , you can download the information and store it on a computer. Youll have to remember to update the info occasionally. NOAA raster charts and S vector charts can be downloaded free.

Other raster charts, like the Canadian BSB charts and the international S charts, must be purchased. The S vector charts are the same format as the S charts but are encrypted so that companies and foreign hydrographic offices can charge a fee for their download. The difference from other programs is primarily in user-friendliness, which of course is somewhat subjective. PolarView somehow displays more crisp and bright colors on the charts than the other programs.

Computer screens, of course, can be adjusted, but we consistently found that PolarView displayed identical charts brighter and crisper than either MacEnc or OpenCPN. Also, the display of instrument information through PolarCOM is good; the default pop-up screen shows positions, speed over ground, and course. Some users might find it too busy when viewing the chart, but the display is very customizable. Setting it up with on-board instruments will be a challenge for non-tech savvy sailors, but there are discussion forums online where you can get help from other users or the programmer.

We found that basic operation of the program was more difficult than with the others we evaluated. The extensive use of the shift and control keys, combined with mouse clicks, seemed very Windows-like and more awkward than the other Mac programs. Another niggle: When you click on an Active Captain icon, only a tiny box pops up, with a couple lines of summary information.

It was several weeks into using the program before we discovered that you can get the full Active Captain information, including reviews and details of services. We discovered this by accident, and our method was not what PolarNavy later advised PS editors to do. We didnt do a lot of integrating other instruments into the charting, but the little we did suggested that PolarCOM is quite good at identifying and using NMEA input, actually better than the other programs. However, integrating may still be somewhat challenging.

If its the only chartplotter that you use, youll rapidly become comfortable with it, but if you use it as a backup to other programs, youre likely to have consistent minor frustrations in using the program. The company also has an iPad app that can be used as a planning and chart-reading tool.

Bottom line: For the price, this is a very good program. Its hard to justify paying 10 times more for a program, such as the expensive Windows programs, that does nothing more. Unlike all the other programs, OpenCPN is free. If youre unfamiliar with open-source software, it is non-commercial software that is created by a committee of volunteers and distributed for free or nearly free. The source-code can be copied and re-distributed to other people.

Donations cover basic costs, such as maintaining a website and facilitating communication among volunteers. To say volunteer is not to say amateur, since the volunteers tend to be experienced programmers. Most often, they actually work in the programming field but may find themselves in dull or boring jobs and are eager to do something related to their other or real interests-in the case of OpenCPN, sailing and navigating.

The authors are listed in the about section of the program, with certain individuals taking responsibility for specific aspects of the program. OpenCPN is a very good chartplotting program that generally works well-after two three-month cruises with it, testers were sold on it. This is not to say that it is perfect-like most open-source software, it has glitches and is still evolving. When users discover a problem, they should report it to the committee, and the committee will put fixing the problem on a to-do list.

Theres no telling for sure when the problem will be resolved, but it should eventually be fixed. For example, the version we are using had the help and tutorial info available only on the Web, so you could not access it if youre off the grid during a cruise. A query connected us to one of the developers who was working on integrating the help section into the program. He walked us through installing it on our version, and it works very well.

This feature was included in version 3. Its notable that some parts of the help section seem to be aimed at the Windows version and may be slightly off for the Mac program. Theres also a very active section on it in the Cruisers Forum website. In general, the documentation of open-source software could be better developed, and thats true of OpenCPN. The glitches in the software are mostly minor. Obviously, you learn not to unplug the GPS. The minor glitches have proved not to hurt the basic functioning of the program.

Closing and re-opening the program seems to solve all problems that weve encountered. An example: Sometimes when you are using the route manager, some of the route names will disappear from the screen-the routes are still there, but the text goes invisible. If you get out of the chart manager and re-open it, the text re-appears. Not a calamity, of course, and no need to freak out and think youve lost several dozen routes that youve created.

Overall, the program works very well as a chartplotter, with all the functions of the most sophisticated programs, except that integrating other NMEA data is somewhat limited no radar interface, for example. Integration is do-able, but if thats essential to you, youd probably be happier with MacEnc, or youd need some techie expertise.

Displaying both raster and vector charts is done well, and raster charts are quilted, as they are in MacEnc and PolarView.
