Furuno's MaxSea software packages offer four levels to choose from based on your navigation needs. Starting with the base level Navigator+, followed by the Commander, Explorer, and Professional. The Commander, Explorer, and Professional levels also come in a NavNet package that allows MaxSea to interface with your Furuno NavNet system via NavNet's Ethernet connection. The NavNet package allows you to view radar overlay, echo soundings, and weather fax directly onto your PC. All of the MaxSea packages offer the ability to connect your GPS and autopilot, download and overlay weather, and perform advanced planning. You can begin using them right out of the box with the 130 US planning charts that are included. Both allow you to use your favorite raster charts from MapMedia, MapTech, Softchart, ARCS, and NDI/Digital Ocean and vector charts from C-Map93, C-Map NT+, and S-57. If you already own electronic charts, odds are that the MaxSea will read them. MaxSea works with more charts than any other platform and displays them seamlessly. MaxSea is also the only platform that supports MapMedia charts with their patented M2 technology. In addition to providing the world's most advanced raster charts, MapMedia's 3D bathymetric charts are the most accurate available. With MaxSea's layers, the amount of text or other elements you can add to a chart is virtually limitless. The overwhelming advantage of layers is that they allow you to segregate your marks and only show the information critical to the task at hand. Information gathering is automatic and intuitive with MaxSea. You can generate logbook entries based on any information coming into the system. You can quickly and easily save tracks, load and read wrecks and rookeries data, and mark your favorite spots or where you've set traps. MaxSea grows with you and quickly becomes the repository for priceless information accumulated while underway. One of the things that makes MaxSea's interface so advanced is its simplicity. Routes can be created or changed in seconds. MaxSea can drive autopilots, upload routes to your plotter, and save them for future reference. Not only does MaxSea provide free access to the most comprehensive weather data available, it gives you the ability to really use it. With a single button click, wind, waves, sea surface temperature, ocean currents, and pressure can be overlaid onto your navigation chart for display while planning or while underway. Detailed tide and current indicators are also displayed over your chart. These graphic displays show the height of the tide and whether it is rising or falling, as well as the strength and direction of tidal currents. Double-clicking on any of these graphic indicators gives you a complete tide or current table for that station. Unlike most PC-based applications that just change the colors, MaxSea offers full day/dusk/night control, which dims the entire PC screen. Every element and chart detail on the screen is adjusted for maximum clarity under any light condition.
