Hi there,
I am working on a water safety and rescue product design thesis. And as part of my research I was hoping anyone reading this who ventures out into the sea could fill in any of these 4 questions.As much replies as possible is truly helpful. Thanks for your time.

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?

If you don't mind some critique, your questions are not well constructed for this medium, and any answers posted will skew your results...

I'll try to help you though;
1. Do you use a VHF radio on your vessel? Yes
2. What size and type is your vessel? 35' Sailing Vessel (sloop)
3. How far would you normally journey out? 1-5 miles (from shore)
4. Do you know the 3 main benefits of VHF over mobile Phones?
  1. One to many communication
  2. All vessels equipped with a radio are supposed to maintain a radio watch (i.e. monitor ch 16)
  3. The Coast Guard monitors channel 16
  4. Range can be greater for a well maintained VHF than for a cell.
  5. Cell phones rely on land based antennas to receive your signal (no nearby cell tower, no worky), VHF radios do not.

Choose any three.

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.

Thanks for all the replies. One other big factor which I am investigating is the fact VHF signals can be traced by lifeboat and coast guard but mobile phone signals can not

I'm not too sure what made you think that but you nailed it. Thanks for the heads up.

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.

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...
