Boating Weather Forecasts, VHF, Cell, Computers, Satellite, SSB, Navtex, Chart Plotter, and home Weather Stations.
At home and before you go boating you can see the latest report on TV or listen to the radio, go online or access your home weather station. Here we discuss the systems available once you get onboard. Article overview & Quick links To fully understand all the weather options available to you, we will discuss, the following options. VHF and Cell, Navtex, Weather Fax and SSB, Chartplotters with XM or Sirius, On board Computers & PC's and Satellite systems Iridium, GlobalStar and Skmate. Learn how to read weather and the tools We also give you some companies that provide Weather Services Plus Weather routing services Also here are weather sources & links.
VHF
VHF is limited to range of 20 miles or so. Like Cell Phones it can offer lots of information if you are sailing within this range
Cell Phone
If you are coastal sailing you can use a high speed wireless network offered by the cellular companies. Once connected you can download weather data. You may pay $70-80/month for this type of service but it may be all you need.
Cell phones can offer weather information including this smart phone from Memory map Memory-Map now offers a version of the award-winning Pocket Navigator package for the Microsoft Windows Mobile Smartphone. On this smaller platform, the lack of a touch screen, or other pointing device, has required a fresh look at the Pocket Navigator user interface. The implementation does not have many of the features found on the desktop or Pocket PC version. However, it does have some unique and powerful features, such as weather overlay, that take advantage of the phone platform.
Next stop we look at the systems for beyond VHF and Cell range What is Navtex? NAVTEX is a worldwide coastal English language telex broadcast system. Navtex provides shipping with navigational and meteorological warnings and urgent information through automatic printouts either as a paper feed or on screen from a dedicated receiver. Navtex is a component of the IMO/IHO Worldwide Navigational Warning Service (WWNWS). It has also been included as an element of the Global Maritime Distress and Safety System (GMDSS). Navtex receiving capability is required to be carried in certain vessels under the provisions of the International Convention for the Safety of Life at Sea (SOLAS). How does it Work? Navtex transmissions are sent via a medium wave frequency from localized stations situated worldwide. The power of each transmission is regulated so as to avoid the possibility of interference between transmitters. Users can set their Navtex receivers to receive specific message types and reject others. Typical range is up to 400NM. Two frequencies are utilized 518KHz (International frequency) and 490KHz (National frequency). Navtex may be difficult to receive in port due to the antenna and high rise buildings
The new Clipper navtex is the culmination of nearly 20 years of
experience in manufacturing navtex instruments. The compact display unit
will grace any instrument panel with its sharp high contrast liquid
crystal display. Standard features of the receiver include 518 and 490kHz
message reception and a non volatile program memory - if your sailing is
confined to one
This device will give you Navtex on your PC.
Economical - Paperless navtex receiver The NX-300 receives NAVTEX messages and verifies the ID of received messages. It features two narrowband receivers, one tuned to the 518 kHz international Navtex frequency and the other to the 490 kHz domestic or local country frequency. Selection is made by a Frequency Select switch on the front panel. See also newsletter on SSB

Coverage for XM and Sirius is the 48 States of the US plus coastal waters. Some have received XM in Bermuda and the Caribbean.
Hardware for Sirius includes this antenna
from Shakespeare Here are some chartplotters set up for satellite weather
The GDL™ 30 and 30A weather data receivers bring XM satellite weather data and XM satellite radio directly to your Garmin chartplotter — without the need for a separate PC interface. For the first time, mariners using the GDL 30 weather data receiver can view the same leading-edge satellite weather data provided to television meterologists across the United States. The GDL 30 receives XM WX Satellite Weather data, including animated NEXRAD weather radar and forecasts, current conditions, surface air pressure, visibility, precipitation, wind data, wave data, storm cell size, speed and direction and surface temperatures, for your boat’s current location or along a projected path. This information appears right on the Map page of your chartplotter, so you can see how the weather will affect your current position
$1,000 hardware and then $30-100/month subscription.
You will have the ability to receive high-quality and comprehensive weather information and forecasting that you can overlay onto your C-Map MAX charts.

Sources of weather for PC's
GRIB programs Gridded binary files are a worldwide standard convention for computer file structure of weather data. Your specialized grib handling software knows the numerical value of the weather parameter and decides how best to display the data. ProGrib
Source of GRIB files on subscription basis. Cost about $36/month or £20 pounds.
With a satellite phone you can add a data kit and browse the internet or receive GRIB files. Safety net is the weather via Inmarsat-C. Inmarsat-C, is a text only e mail system between 70N and 70S. GMDSS safety distress signal sends out MMSI number lat & lon, course & speed, when the red distress button is pushed.. Priced per character.
Iridium mainly aimed at voice communications. Iridium operates 66 LEO satellites and is truly global. Handheld telephones can transmit to this lower orbit, without the need to be stabilized. Iridium operates at 2,400 bps same as mini -M. The department of defense uses Iridium.
with Globalstar you get Ocens text & images, e mail and WeatherNet. With OCENS XWeb service you can achieve effective data transfer speeds of up to 56 kbps over the Internet using your Globalstar satellite phone and data kit.
Skymate has received full type approval by NOOA for its
VMS Vessel Monitoring System which is required for fishing vessels.
Weather downloads are also a benefit. The outgoing message is read by computerized voice and delivered to a phone number. Skymate is not GMDSS capable. The antenna is a 38 inch whip. Pricing is per character transmitted, ranging from a $16/month plan for 8,000 characters sent and received, to $70/month for 50,000 characters. Skymate coverage map
