1 Onboard Communications WxLive! Session 1

2 Expectations Broad Overview of Comm Equipment Compare and Contrast Them Links and Resources Question Management

3 Objectives For the Series How do we get weather info onboard? How do we decide which equipment? How do we start the planning process Suit needs for acquiring wx info! (this Session) How do we interpret wx data acquired? (Session 2) How do we use that info to plan strategy? (Sessions 3 and 4)

4 Hosts Bill Biewenga Over 400,000 nm at sea Multiple speed records, numerous races and deliveries 37 Transatlantics as well as passages through virtually every ocean of the world Author & lecturer Lou Roberts Co-owner Weather4Sailors.com Winner 2008 Marion to Bermuda Short Handed Trophy Corporate consultant in instructional media and training

5 Speakers Phil Lee, Cay Electronics Mark Freeberg, Ocens Jim Corenman, SailMail Rick Garrison, KVH

6 Technologies Covered VHF SSB / HF Satellite

7 Weather Data Typical weather products that can be received and used offshore while underway*: Voice forecasts Text forecasts Weather faxes Weather images (satellite, radar, gulf stream charts) GRIB files Buoy data (current conditions) *subject to race committee restrictions

8 Receiving Weather Data Weather products are received while underway in one of the following ways: Voice broadcast Dedicated weatherfax machine File download attachment Internet Browser (view webpages)

9 VHF Within a Weather Context NWS Marine Forecasts DSC info available in our Resources List Technology Issues Range Masthead vs handheld Emergency antennas Main Installation vs handheld Special regulations for 25 W output How do I receive VHF weather broadcasts?

10 VHF Technology Issues Range Installation Technical details Frequencies Use in foreign countries Race rule limitations

11 NOAA Weather Channels in MHz WX WX WX WX WX WX WX

12 SSB / HF Radio Technical Issues Licensing Coverage areas global w/atmospheric constraints Transceiver vs Receiver Software-driven solutions (blackbox) Wx Fax Navtex Telex Graphics Maps GRIB Files

13 Stand Alone Wx Fax Furuno Weather Fax 408 ($2,600 - $3,400) Furuno Weather Fax 410 ($8,500 - $9,000) JRC Jax-9A Weather Fax ($2,200 - $2,900)

14 via SSB/HF Radio Why get ? What can I get through ? Text Graphics (GRIBs) How do I use SSB to get ? Are they allowed during offshore races? Do I need additional hardware?

15 SSB/ HF Radio SSB Unique Qualities Able to broadcast, receive common broadcasts Often already installed onboard Costs Coastal radio station talk time is not inexpensive Ham radio is inexpensive

16 Satellite Communications Types of weather information available Weathernet as an example Graphics (including GRIB, maps, satellite pictures) Text Coverage areas Speeds available Costs
