Navionics Alternative for marine GPS

Below is a long list of Navionics alternative solutions for marine navigation. First, let’s make the distinction between Navionics charts and the Navionics Boating Marine & Lakes app clear. Boating Marine & Lakes app does use Navionics charts. However, it is by far not the only way to get Navionics charts for marine navigation. Many of the chartplotter chips have Navionics charts on them. It’s also available in other sources, and there plenty of chart alternatives to Navionics marine charts. Are you looking for a reliable marine grade laptop with GPS for marine navigation? Please contact me! Read on to see a long list of marine GPS software which can provide a good Navionics alternative below.


i-Boating marine navigation Navionics alternative

The software has access to inland rivers and lake charts, as well as satellite overlays. It may not be as refined as some of the above alternatives, but the pricing is quite reasonable. Runs on my midrange or premium units. It requires Windows 10 on PC and also runs on Android and iOS devices.

Rose Point Coastal Explorer Navionics alternative

Rose Point, the makers of Coastal Explorer, are based in Seattle. It’s deservedly popular with many recreational boaters along the US & Canada West Coast. Many of my clients run this package on one of my navigation laptops. They provide excellent customer support. The software has extensive functionality, and abundant chart sources. It’s fairly heavy and requires midrange or premium units out of the ones I offer.

OpenCPN budget Navionics alternative

OpenCPN is one of the most well-known software packages for marine navigation. This is the package that I supply standard with my navigation laptops! It supports a large number of affordable digital radar models. It has very low system requirements and runs on even single core computers acceptably well. The latest version has a polished interface, and is quite easy to use. You can’t get small inland lake maps, unfortunately. It runs well on any of my navigation laptops, including the basic models.

TimeZero high end Navionics alternative

An incredible navigation package which requires no introduction, TimeZero has very extensive functionality. The only real downsides are that it be can be slow to load, and will empty our your wallet pretty quickly. If you’re looking for the best of the best, look no further. I have a page with multiple video tutorials for TimeZero, if you want to check out the functionality. TimeZero also allows you to use Navionics charts which you purchase from them.

TimeZero expensive but good i-Boating alternative

P-Sea Windplot PC marine navigation software

This is an old school piece of software which has been around for over 20 years. Nevertheless, it’s supported and has access to the latest charts. Why fix something that isn’t broken? It has pretty extensive functionality with radar and even fish finder support. This is more geared towards commercial fishing than recreational boating.

Olex AS marine software for commercial fishing

This is a high end bathymetric package popular with commercial fishing fleets. The cost is high, the capabilities are impressive. You can do bottom surveys and generate your own highly detailed charts.

EuroNav SeaPro nautical GPS software

This is a UK company that I’m not too familiar with since I’m based in North America. The interface looks pretty clean, and is fairly customizable. The cost does appear somewhat higher than some of the other options below. They do provide quite a lot of equipment, so it could be convenient.

PC Plotter marine navigation software

This is another smaller company. PC Plotter software can use data from Navionics cards: Navionics+, Gold, SonarCharts, Platinum and Platinum+, Hotmaps and Hotmaps+. You can likely expect direct and very helpful support. The pricing is reasonable. Seems like a great option to consider if you already own a Navionics card.

StarNavPilot marine navigation app for Windows i-Boating alternative

This software is made in France, and I am not very familiar with it. The interface looks very customizable with widgets of various sizes which can be docked pretty much anywhere. It is current, and up to date. It comes with French coast charts included, and the price is very reasonable.

Expedition Marine for Windows

This software is geared towards sailing and yacht racing in particular. It’s an old school software that’s been around for ages, yet is still currently supported and up to date. The interface is not what you would call modern in 2021. It is geared towards weather routing and sailing. It supports a lot of marine charts, including: S-57 ENCs, S-63 ENCs, BSB RNCs (v1-5), C-MAP 4D, C-MAP MAX/NT+, NV-Verlag, Softcharts, Maptech PCX.

Why use a navigation laptop or tablet as a chart plotter?

My navigation laptops can be much more affordable than GarminLowranceSimradB&GFurunoHumminbirdRaymarineSi-Tex. I will also support the GPS laptop you purchase forever! Furthermore, I believe that some of the commercial chart plotter brands gouge their customers. Large companies force their clients to upgrade. They stop supporting older units with chart and software updates. In addition, they charge outrageous fees for simple things like a larger screen size. I don’t do any of these things, and never will – guaranteed! Moreover, please take a look at other advantages as well. A navigation laptop can offer a compelling alternative to major brands.
