1. Do you use a VHF radio on your vessel?
2. What size and type is your vessel?
3. How far would you normally journey out?
4. Do you know the 3 main benefits of VHF over mobile Phones?
1. Yes
2. 30 ft sloop
3. Less than 25 miles
4. This one is a little tough as I think there are more than three benefits but here are three off the top of my head. Longer range/able to contact other ships to relay messages, longer battery life, ability to hail any and all stations in range.

There are several disadvantages to a VHF over my phone. I can't play words with friends or watch the Gangnam Style video, just to name a few...

....... and so we bid a fond farewell to Sean and Tony. I'm sure you'll all join with me in wishing him/them/it well as they set sail on that lonely voyage across the Sea of Banishment.

1. Do you use a VHF radio on your vessel?YES
2. What size and type is your vessel?37' sailboat
3. How far would you normally journey out?up to 10 miles
4. Do you know the 3 main benefits of VHF over mobile Phones?1. 'party line' 2. Coast Guard monitors 16 3. Rugged marine unit with better range
There are many more than 3 main benefits. DSC Mayday, Mayday Relays Signal can be located by RDF. SAR aircraft use marine VHF, Ship to ship channels, communicate with lift bridges and locks...shall I go on? Cell phones are for calling home to say the breeze has died and you will be late for supper.

Safety & Rescue Thesis

Yes
40' sailing sloop
Normally 10-12 miles
Yes - big advantage I see is the coast guard monitoring/safety aspect, and the ability for everyone in the area to know when someone needs help.
