I don't think what I want to do is unreasonable. I am sorry that some folks here responded so strongly to my comments about the purpose of the marine VHF rules. Maybe they can take a lesson from you... My boat sank off Mitkof Island at night in the winter of 1971. There was moss ice on the water and the air was -20. I had sent a distress call on the radio. A tug cut its tow and pulled me out of the water and resuscitated me. When the boat sank and I went into the water it felt like I had been hit alongside the head with a 2X4. I was mercifully out of consciousness within seconds. I have to say that it would be a very quick way to die. I have to say you were indeed a lucky one to have survived your experience. What you felt is called cold shock, your body's response to immersion in cold water. It is worse with decreasing temperature, but actually reaches it's maximum between 50 and 60 degrees. Colder temperatures than this do not produce a more severe effect because your body is already responding at its maximum. There is often an initial gasp reflex on sudden immersion resulting in a lung full of water which is typically fatal. If you survive this, you lose control of your breathing. It takes some 5 to 15 minutes for you to lose the ability to use your limbs depending on the water temperature. I grew up alongside the Pacific Ocean on the North Coast of Oregon. The water temperature was in the 40s. We could swim in that surf for about 20 minutes before we turned blue. It was great fun in the surf but pretty dangerous. We were forbidden by our parents to do this, but being forbidden made it better. :-) The gasp reflex and cold shock can be mitigated by acclimation. By going into the cold water often you likely built up some resistance to these effects. This will wear off in about the same amount of time it took to acquire it, so it would not have helped you by the time of your accident. I can say from my experience that any kind of cold water can kill. When it is at freezing it kills very quickly, when it is in the 40s it kills a little more slowly. I think the temperature and time probably could be made into a formula for death. That is actually dependent on a number of other factors such as your body fat and of course clothing you are wearing. Increased body fat extends the time you can be immersed before suffering from hypothermia. Physical conditioning does nothing to help. Like I said before, if you can keep from being cited by the FCC, a marine radio would work pretty well for your purposes. It is very short range and if you are using it in a small lake, the chances of your being monitored are remote. Also you would not cause interference to anyone else. Yes, I will be kayaking this weekend and will discuss the issue with some of my fellow paddlers. I'm sure they know more about this than I have heard from them before. Hi Rick Yes I was lucky. My wife was listening to the radio at home. I had a transceiver on 2182 at home. Oh dear, my bad it was illegal. She heard my distress call and was on the edge of her seat. She then heard a report from the tug that I had been recovered and was not breathing. She thought the life she knew was over. Very traumatic for her, but not so for me. She then heard the report that I had regained consciousness. These events give one great respect for the elements and having a radio. Yes, that is why I want to support the kayakers on the paddle next week, as a safety measure. Last year we had a stiff wind from the north which created significant waves at the start and a number of paddlers were not able to make it all the way. I was part of the team which tracked their progress and got them off the water. Cold was not an issue in this case. Cold water makes such events much more dangerous. That is why I want to have good radio communications. I will be doing what is required to do this legally even if it means sitting in a boat at the edge of the water. Please take a look at this web site and let me know what you think. It currently has a definite sea kayaking focus, but the intent is to ultimately be inclusive of anyone who may end up in cold water, even if not in a boat. If you would like to share the details of your story it would be appreciated. You can contact me at the email address gnuarm at gmail dot com http://www.coldwatersafety.org/ Get a "cartopper" boat and strap it to a ladder rack on your truck - put the "radio operator" in the boat. |

I realized that my friend and I had become adjusted somewhat to the cold surf. We did in fact first just go in for 5 minutes and had to get out. As we progressed during the summer we got up to 20 minutes. There are some details I left out about my immersion in very cold water. I don't know if they are important to you or not. I could fill you in on the details if you chose. |

So you probably can assume that they mean you can't be standing in the water, as in on the beach, or in a bucket of water, as in one of the Disney Pirates of the Caribbean movies. Then put the boat in the water. That makes sense anyway, since if an emergency comes up, you'll need the boat. Now maybe this long off-topic wandering thread dealt with that originally, and if so, then the solution is simple. Marine walkie talkies in the kayak, a boat ready for rescue work on water, someone with height and a scanner to wait for emergency calls, and cellphones for that person and the rescue boat. A call comes in, if the rescue boat doesn't hear it the listener higher up will, and calls the rescue boat with the cellphone. Cellphones don't even have to be used, GMRS or CB or hey, amateur radio, can all be used. Once the rescue boat is within range of the kayak, they can ue the marine band, since both are boats and allowed to use the band. Michael |

That is why I want to have good radio communications. IMHO you would be far better off having them get cellphones with GPS in them and have them phone in with their exact location if they need help. You don't need a waterproof phone, if you double bag it in one of those plastic bags sold to boaters to keep things dry, you should be ok. I don't know how close to the shore they intend to stay, but if they get far enough out, the conversation about where they are is something like: "What do you see in front of you"? "Water". "What do you see behind you"? "Water". and so on. Or even worse, when the answer to that question is "Fog". I take it you have not read the full thread, that's ok. Cell phones only work within range of a tower. The bay is miles wide and many areas where we paddle have little or no cell phone coverage. Lake Anna is the same. I have needed to use my cell phone while paddling only to find it can't dial a number. We always carry cell phones because they are useful when they work, but we never rely one them. In fact, we never rely on any one safety mechanism working. We always have a backup or two. That's why the radio is useful. It can work when the cell phones don't and it can do things a cell phone can't, like reach someone close by without knowing their phone number. -- Rick |

Lake Anna is the same. I have needed to use my cell phone while paddling only to find it can't dial a number. Why are you so belligerent? Yes, I have read the entire thread, and I am aware of the size of the bay. GSM cell phone coverage is limited by timing to 35km, about 5-10 times the range of a VHF handheld. If an 850 mHz GSM phone is not going to work where you are then a handheld won't reach land either. We always carry cell phones because they are useful when they work, but we never rely one them. In fact, we never rely on any one safety mechanism working. We always have a backup or two. That's why the radio is useful. It can work when the cell phones don't and it can do things a cell phone can't, like reach someone close by without knowing their phone number. But that was not the point of this whole ****ing contest. It was based upon your mistaken understanding that you could put a 25 watt boat radio in your truck ON LAND and reach kayaks in the water. The laws of physics being what they are, yes you could probably go fairly far with a 25 watt radio, a good antenna and height and with a receive preamp and a beam antenna be able to hear across the entire bay and possibly be heard. Since that is not an option, you are stuck with a handheld radio and a rubber ducky, which will get you a couple of miles on a good day if you are on land, and more if you are on water. Come to think of it the best suggestion was to have someone build a decent listening post on high ground (or with a tower) and relay information to someone via cell phone on the water. The are AFAIK no restrictions on land based fixed receivers and you could take old Motorola Maxtracs (available for almost nothing these days), connect them up to 3 element beam antennas, add a cheap receive preamplifier and hear everything on the bay if you had enough receivers with their antennas spread in an overlapping pattern.
