Navigator Pro blends the looks of paper with the facility of bytes.

THE MAGIC OF LAYERING: MaxSea navigation software, distributed by Furuno, offers a flexible mix of navigation data are all there. Two versions, wide ($260) and megawide ($390), are offered. In addition to the charts, C-Map offers such online services as real-time updating and weather. On a weekly basis, sailors can download "Notice to Mariners" changes with a click of a button. Weather forecasts up to 10 days out can be overlayed directly on the charts.

Speaking of weather overlays, Northport Systems recently added that service as a free update to its suite of Marine ENC Version 4 charts. The charts ($200 for the entire United States) are based on the public-domain

THE MAGIC OF LAYERING: MaxSea navigation software, distributed by Furuno, offers a flexible mix of navigation data electronic-navigation charts provided by NOAA, with lots of value-added features like three-dimensional perspectives, marine services, and superimposed streets. The weather data comes by way of e-mail in GRIB files that are small enough to be handled by such low-bandwidth systems as the SSB-based SailMail program. The files typically come in between 2 kilobytes and 5 kilobytes.

For PC users, Maptech recently introduced its Chart Navigator Pro suite of charts and software for U.S. and international waters ($500). The package combines raster and vector maps with overhead photos, Coast Pilot, Light List, tides and currents, weather, and more. To run it,

you'll need Windows 2000 or XP and a DVD ROM drive.

MaxSea navigation software, distributed lately by Furuno, has recently introduced its 12.5 version. Available in three versions—Navigator+ ($580), NavNet Commander ($1,430), and NavNet Explorer ($3,300)—the software has long been popular among sailors for its flexibility. It will accept cartography from many different sources, including Softchart, Maptech, C-Map, MapMedia, and the Canadian Hydrographic Service. When used in conjunction with Furuno's Navnet network, it provides prediction of tides and currents, radar overlay, and seamless quilted charts. Updates in the 12.5 version include weather routing, an AIS module, and a simpler system for managing routes and waypoints.

uses proprietary cables and connectors and enables other Raymarine SeaTalk2 devices to talk to each other while maintaining near-transparent NMEA 2000 compatibility. SeaTalk2 products aren't NMEA 2000 certified, but Raymarine offers the ST290 Data Processing Unit and the E80 and E120 radar/chart plotters that are fully NMEA 2000 compliant and certified.

Xantrex's Xanbus is a proprietary protocol that builds on the NMEA 2000 interface and is said to provide unique configuration and control for network-managed power. Xantrex uses proprietary cables and connectors but provides a gateway to filter and translate Xan-bus messages to seamlessly connect a Xanbus network to a NMEA 2000 network. The Xanbus gateway is pending NMEA 2000 certification.

Yamaha's Command Link is a proprietary implementation of the NMEA 2000 open protocol. The proprietary cables and connectors used to connect the outboard motor to the multifunction gauges aren't NMEA certified. The Command Link multifunction displays, tachometers, speedometers, fuel-management gauges, and triducer are NMEA 2000 certified.

Moritz Aerospace, a Carling Technologies Company, produces the OctoPlex system for the management of shipboard power, circuit protection, and monitoring. The system uses dual NMEA 2000 networks with automatic network switchover if a network fails or is severed. The system is protected from obsolescence with the availability of software upgrades and the installation of NMEA 2000 components. The communications protocol is certified to NMEA 2000.

E-T-A Circuit Breakers' PowerBus network is a distributed electrical power-management system for control of AC and DC circuits and alarms systems in marine applications. Power nodes are distributed around the boat to reduce the amount of heavy current-carrying wires; circuits are switched electronically. This system is based on the SAE J1939/NMEA 2000 CANbus. E-T-A hasn't pursued U.S. certification and doesn't use an NMEA 2000-compliant physical layer.

SmartCraft is a proprietary network that uses the control area network (CAN), but there the similarity with NMEA 2000 stops. SmartCraft was developed by Mercury Marine as an alternative to NMEA 2000 and is now under the control of Mototron Corporation, a subsidiary of Brunswick Corporation, the parent company of Mercury Marine.

A closed system, SmartCraft is controlled by a main controller, usually the engine, and isn't plug-and-play; systems are planned ahead of time, and devices are added to the network using network tools. Smart-Craft is a managed-data bus system, and products must be certified both individually and with other products in the SmartCraft networked community. A full system can consist of up to three CAN networks: CAN X for critical engine systems, CAN P for engine diagnostics and backup, and CAN V for such systems as generators, navigation, and power-circuit switching. The physical layer uses non-isolated interfaces and unshielded cables and employs automotive type connectors.

The network is used by companies in the Brunswick family, including Mercury Marine, Northstar Technologies, and Navman Ltd. Also, through a partnership with Cummins Power Products, it's used on the Mercruiser line of diesels and Onan generators. Through the "SmartCraft Networked" program, Mototron licenses outside companies to partner in managed SmartCraft systems to deliver fully integrated vessel systems. They include Airmar Technologies, Xantrex inverters, FW Murphy engine/generator controllers, and Faria In struments, each of which also produces NMEA 2000 products. Others that don't also make NMEA 2000 products include Beede Electrical Instruments, Medallion Instruments, DNA power-switching products, BEP Marine switches and circuit breakers, Domestic Corporation's marine air-conditioning systems, and Kohler gasoline generators. Another Brunswick company, Integrated Dealer Services (IDS), produces diagnostic equipment and is set up to provide training, installation, and technical support for SmartCraft.

High-Speed, High-Volume Applications: Networks for systems meant to carry video throughout the boat typically rely on an Ethernet bus. Here are some systems you're likely to encounter.

Furuno's NavNet is an Ethernet system using the same network technology seen in most professional office environments. NavNet is used to network selected Furuno radar, chart plotter, GPS, sounder, weatherfax, and remote-display products. Any two devices can be connected directly, but three or more require the use of a 10BaseT- or 10/100BaseT-type Ethernet hub. NavNet uses open-architecture TCP/IP protocol for the transport mechanism, and although the actual data is proprietary to Furuno, it's partnered with MaxSea, so Furuno information is available on laptops using MaxSea software.

SeaTalk High Speed is the newest generation of Rayma-rine's high-speed networking approach, replacing the HSB and HSB2 networks. It's an Ethernet-based marine network provided in selected products that supports up to eight nodes to give access to radar, fish-finder, chart and instrument data, and navigation information. Two devices can't be connected directly together; rather, the cables from each device connect via a Raymarine

How To Have A Perfect Boating Experience

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
