Title: pfd's
Post by: alantani on December 08, 2008, 06:39:51 PM
yeah, yeah, yeah, i know that arguing with the us coast guard will get me nowhere, but we'll try again.

in every situation where there had been a fatality, i think the guys could have gotten out alive if they were wearing a pfd and had a hand held vhf radio. this last one was the exception. apparently, these two guys zippered up the plastic behind them which then completely enclosed the helm station (not the forward cabin), then it filled with water in a matter of seconds. they basically could not unzip or slice their way out of this plastic bag. i did not hear if they had pfd's. i did hear that the diver removed their epirb. yeah, the epirb was trapped under the hull with the crew.

so here's where i am now. the pfd's all have a strobe, a whistle, a 3-pack of flares and a light stick. all pfd's are now equipped with the new standard horizon vhf radio that has an integrated gps. i have a life raft and a handheld epirb. i also have an epirb that will automatically depoly if the boat rolls. it is located on top of the hardtop. i fear that it will release and then get caught underneath the upside down hull, trapped along with the life raft and the handheld epirb.

this standard horizon radio/gps is $250. if i was going to recommend one piece of equipment, i would recommend this radio and that it be worn by the skipper. for those of you that hitchhike alot, i would recommend that you bring your own pfd. you don't have to pack it the way mine is, but at least clip a radio to it. alan

Quote from: FINSEEKER;502233Alan, your logic is all very sound. There is really no argument with the way you have outfitted your boat, or the folks trusting their lives with you...our disagreement is in what we consider the most important piece of livesaving gear (once you get beyond the PFD and a means to stay thawed out in cold water) the EPIRB is fool proof, only has to be activated, and you will be found. The radio for all the good it will do, also depends on line of site signal, your ability to read your position in a very stressful situation (and not transpose the numbers)(or have the GPS set up for the position in degrees, minutes and seconds and mistakenly say point instead of hyphen between the degrees and minutes which would cause an error of many many miles), the ability of the person transmitting to be able to articulate a location accurately if the GPS is somehow disabled, and the ability to transmit your position even if you become unconsious. Remember also, you are the exception when it comes to being prepared, and knowing the capibilitys of your equipment and how to use it. How well do all your passengers know how to use the radio, and call the CG and give a position while treading water in 52 degree water with their teeth chattering and someone next to them going down for the count.

So Alan, its a difference of opinion, and I stand by my thoughts that if I'm on a sinking boat, and had one piece of equipment to alert the Coast Guard (regardless of where I am and my physical capibilites) it would be the EPIRB...hands down, without exception....except, if your boat sank in the middle of the salmon, halibut or even albacore fleet the ability to contact a passing boat would expidite your rescue...thats the only time I'd trade the radio for the EPIRB.  Had this boat not been found right away (do we know how long it had been adrift upside down) and the epirb would have floated away (I'm assuming it was in the cabin) the epirb would have alerted rescue agencies of the problem imidiately (probably much sooner then was the case). I also have a feeling the EPIRB is more water tight then even the best handheld vhf radio (could be wrong).

So Alan, we are simply in somewhat of a disagreement with regard to the most important piece of equipment you can have on your boat to alert the Coast Guard of your position and the fact that there is an emergency in the event of a major event (sinking, fire man overboard expically if the captain on the boat alone assuming personal epirb or handheld vhf) or even a simple breakdown if out of radio range...I say the EPIRB, you I believe say the handheld waterproof VHF or even VHF. The other part here is how well equipment is maintained, while the Coast Guard highsites i believe publish a reception range of 50 miles (don't quote me on this), this is assuming the vhf putting out an optimum signal which means perfect antenna connections etc. You are I'm sure on top of this but most of us (me included) are not. The EPIRB requires no maintainance, the battery experation date is clearly marked, and if an auto release model, the hydrostatic release also has an experation date...BTW, the problem with the hydrostatic release is the depth of water at which it activates which lends the release useless on a capsizing situation where the boat doesn't sink. Thats why having the EPIRB handy for manual activation is IMPORTANT.

One last thing, everytime you argue this point with me, it is healthy because it brings awareness of different options to everyone who reads these little squabbles (that I think have been going on for at least 6 years)...keep it up!

Handheld radio saves kitesurfer
Carolyn Jones, Chronicle Staff Writer

Sunday, March 14, 2010

(03-14) 16:00 PDT SAN FRANCISCO BAY -- The Coast Guard, with help from a Good Samaritan, rescued a stranded kitesurfer after he used a waterproof, handheld radio to call for help.

--------------------------------------------------------------------------------
"This is a great example of why we urge water enthusiasts to carry these radios," said Coast Guard Lt. Jeremy Pichette. "Without the radio, things might have turned out very differently."

The unidentified kitesurfer lost his board at about 5:20 p.m. Saturday while he was four miles north of the San Mateo Bridge and four miles east of San Francisco International Airport.

Treading water, the man used a VHF radio, which he likely kept in a pocket of his wetsuit, to contact the Coast Guard. The agency notified all boaters in the vicinity and dispatched its 25-foot response boat, an MH-65 Dolphin helicopter, a Coast Guard Auxiliary boat and the Foster City Fire Department boat.

A mariner on a small pleasure craft reached the kitesurfer first, about 30 minutes after the initial call. Soon, the Coast Guard vessels arrived, and the kitesurfer was transported to Coyote Point Marina, where paramedics took him to Sequoia Hospital in Redwood City.

Pichette said the kitesurfer is recovering. The water temperature Saturday afternoon was about 54 degrees Fahrenheit.

The Coast Guard strongly recommends windsurfers, kitesurfers and others to carry a VHF radio in case of a mishap. Saturday's incident was the first kitesurfing accident in a few weeks, but in the summer accidents are almost daily events, Pichette said.

In addition to a radio, boaters are encouraged to carry a flare and an emergency position indicating radio beacon, which transmits a location to the Coast Guard if the vessel becomes submerged.

EPIRB vs. VHF Radio

There are pros and cons to both sides of the issue of whether a VHF radio or an EPIRB is more important. A responsible boat owner who ventures out on large bodies of water would have a life raft and both an EPIRB and a 25-watt VHF radio with a good antenna system. A GPS unit is almost as much a necessity as a fire extinguisher or a first aid kit. Whether the PFDs worn by passengers and crew have a portable radio or personal EPIRB would depend on several factors; distance from shore, likelihood of other boats in the area, presence and frequency of USCG patrols, personal budget, and probability of occurrence vs. frequency of exposure to risk. In an ideal situation, each person would have their own radio and EPIRB.

   If a boater only goes out in the bay or fishes within radio distance of land stations, a VHF radio would probably be more useful and cost-effective. I'm disregarding the "what-is-your-life-worth" issue for this discussion. Even a handheld radio, if rated as submersible and figuring a 3-8 mile optimum range, may suffice. In the past several years, I haven't spent any time at the California or Oregon coastline without seeing a Coast Guard helicopter flying along several times an hour. If you're going offshore or cruising long distances along the coast with few opportunities for radio contact, then the game changes. If the captain isn't familiar with the area he or she will be in, then an EPIRB is part of the investment in safe boating.

For someone who doesn't have their own boat and must rely on charter boats or the generosity of others to go fishing, a risk analysis is recommended to make an informed decision. Offshore boating has a higher risk than inshore due to the expanse of the water and the unlikelihood of another boat being nearby to hear your call or see your plight. Do you go out often thereby increasing the frequency of exposure to higher risk? Do you occasionally or often go out on half-day boats that don't venture far from shore? Offshore boating where you may be out of VHF radio range should call for individual EPIRBs to be carried by each person. A portable radio is still invaluable once rescue personnel are in the area for passing critical information and guiding them in. I've spent several years as a helicopter and fixed-wing crewman looking for people and things on the ground and then having to talk to them to find out how I could best help them.

   Because I most often fish near the shore, it is hard for me to justify an EPIRB when a handheld VHF radio will get me "more bang for the buck". I have a Type III PFD set up nearly the same as Alan has for his boat: whistle, aerial flares, strobe, light sticks, and signal mirror. The VHF radio will be added before I go out again. If I'm offshore fishing, I'll have a decent chance of survival with an electronically well-equipped (as in properly equipped) boat. My objective is to increase my chances for survival. If I wanted a 100% guarantee on survival, I probably wouldn't go out at all.

I think this depends on where you are going to be fishing, BUT, I say get both a hand held VHF and either a PLB or an EPIRB.  I have the PLB.  Both the PLB and the VHF will be clipped to my inflatable vest when I go off shore.  For inshore, I have a lap belt style inflatable that I will try to use with the VHF only.

By the way, I also have a knife and fishing pliers on my inflatable belt.  I'd like to think I could have cut my way out of that situation described above, but who knows what your reaction will be in an emergency?

Being a kayaker, i wear my PFD, and have a radio, whistle and signal mirror with me at all times.  I also wear a farmer johns, and a kayak jacket.  For the times I have gone in, they have been a God send.  All the fancy Grudens in the world will not save your body warmth if you go in, and can't get out quickly.  Big blue is very unforgiving, if unprepared.

This year I outfitted my PDFs. (4) anyway because usually that's the number of people I have onboard.
Each has a vhf radio, strobe, whistle and flares, I bought a new ditch bag, USCG approved floating with tethers, an epirb which wil stay in the ditch bag.  I have always carried an inflatable rescue pod.  
 There is no absolute guarantees on any of this gear, I know of fully equipped boats going down all souls lost and Epirbs and life rafts drifting off alone.  
In a real emergency you may have only seconds to make the correct decision or less! There is not time in an emergency to go below decks, dig around and find your pfd put it on much less insure your passengers do.
Locate your handheld, get your life raft overboard.  Sounds terrible but it's true and you can't plan for everything.
I keep my rescue pod onboard, when I leave the Harbor for anything more than near shore fishing (I sometimes go over 100 miles offshore) I set it on the hardtop, no straps.  If the boat rolls hard it will go over.
My ditch bag will stow in close proximity to the aft deck where anyone can grab and jump or throw it over.

And now I have class B AIS tranciever and added PLB and MOB devices to life vests.  Why argue with which is better, VHF or PLB when you can have both!  I feel better and that's half the game right there.
I got something Alan doesn't got!
These are the preparations I make and pray I nev r have to use.  
But just in case, all my grandkids are learning to use the radios and we will be practicing man overboard and abandon ship drills this spring with all gear.  It's going to be fun!

I only use type 1 jackets with strobes, whistles and reflective tape. Some are stored under the  top in netting  the extras in a forward hatch. I have a PLB for me but not for all.  I do have some poly rope and carabiners to latch everyone together along with a floating cooler with potable water bottles in it. That is my plan that I hope I will never use. I think I will add some expired flares to the mix with the other jackets and keep my normal safety kit attached to my jacket. I fish in warm water so hypothermia can happen but is not the first threat.

I think e very high percentage of fatality in the sport fishing world, when looked into they can tell you they all had life jackets, none of them were wearing them.  there never is time to grab one and put it on in an emergency.  put it on before the boat leaves the dock, if its not comfortable to wear doing anything on deck then its the wrong vest, get one that is. don't put yourself in the situation of having to make a choice of grabbing your ditch bag, or your life jacket, or god forbid a child.
just my .02 and its easier for me being older I finally recognize it is possible that I am mortal.  not likely but possible!

I read somewhere that some accidents happen as people board the boat, I make it mandatory to put on a life jacket after kids/grandma/guests get out of the truck before they start walking down the ramp.

Few weeks back in MI a fisherman died after he feel into the water when he was leaning over to net a fish and a big wake from a another boat flipped him over, he was not wearing his life jacket.

FACT
My first "rescue" was my younger brother, when he was 5 and I was 9. The rule was lifejackets before you got on the dock. My brother fell in off the brow to the boat with his jacket on and the brother between us and I fished him out. That isn't the way it would have gone down without that lifejacket. He smacked his head pretty hard on the way down and wasn't plugged in enough to save himself.

Having worked 911 in Philadelphia for 24 years this thread has a whole lot of life saving information. I have handled a few "distress" calls from cell phones. First thing I would tell caller to have everybody put on their PFD's and call USCG radio room in Philadelphia with my cell phone and sent out the proper help. Most did not have any marine radio on board.
The USCG Auxiliary courses should be taken by all boaters before going out on the water. I like the bosses PFD setup.

Just ordered Class Ones for the Thorhammer which hopefully gets maiden fishing trip next month. All have reflective tape, strobes, whistle, vhf (per the Boss) and I will have EPIRB by then as well. Back up GPS and VHF are going on the boat, set up to plug directly to batteries or to the massive Dewalt jumpcharger I just got in case the three batteries (all new) crap the bed. ditch bag with first aid gear and epirb, tethers, and additional dry bag with water and rations. Three extinguishers, one in cabin and one in each seat caddy in helm area. First aid kit also in caddy for on-deck issues, separate from ditch bag.

My wife is a critical care flight nurse and frequently lifts personnel from military bases and other situations more nasty than a hangnail, you might say. My captain is a retired USCG Chief Bosun's mate who ran SAR for 25 years in the waters I fish, and 100 Ton licensed. So I do what they tell me.

My buddy and I ran into a situation two summers back where the weatherman missed the forecast by about six wave feet, and wind by 10 knots. We lost electronics 60 miles out and had a nice wet cruise home at 15 knots, going through inlet in the dark with no sounder (fortunately we could see land and rips) and home at 10pm, after we waited out the t-storms to get off the beach and head inland. We were safe enough in that particular boat, but we still suited up and kept in contact with CG the whole way.

Got a fishing style PFD( no tackle in the pockets, just safety stuff) and in it is a PLB with built in GPS & strobe light, a knife, and a waterproof cellphone/wallet holder.
How exactly would you use a hand-held VHF radio?, i.e., do you godda program channels into it? If so, which ones? Whom would you call first with the VHF? Would it contact the CG? Or is it for other vessels in the area?

Gregg,
Last December I had the same question,
I found this video to be very helpful.

https://www.youtube.com/watch?v=l2dCSKR1jVs

I am assuming your handheld floats and is waterproof,

You broadcast a distress on channel  16,

My walleye club now requires all participants to have marine radio on board.

If you have GPS, you might also MMSI capability, if yes reg is and use that feature in case of emergency.

I need to do my registration, can't figure out what I will call my little boat for my call sign  :D

When you are under way you are supposed to monitor Ch 16 and render assistance if needed, also if you call the Coast Guard or sea tow or another Boat they will tell you what channel to go to that way if another emergency calls in CH 16 is free, but then you also get some who think that the VHF is there cell phone and that's against the law.

Joel,
When I checked the channel list, I saw some channels that could be used for "hailing" other boats, sorta like open channels. Is that not the case?
Title: Re: pfd's
Post by: Ron Jones on April 18, 2019, 04:59:35 PM
It is the case. Channel 16 is the international hailing channel, but there are other local channels typically used for hailing. You used to be able to find that information in some Coast Pilots or NOTAMs, but not so much any more.

Your right  Ron, but over 90% of the boaters use 16 , we all know about the secret channels that the commercial boats use but most of them are on Single side band radios.

The one thing I would point out now that I work on a Navy base and see the sailors running around in blue camouflage...if you don't want to be seen then wearing a dark colored PFD is the way to go.  I just hope the Mighty CG can find you, which is why in the world of Kayaks it is better to stick out then blend into your background.  Fall off of your boat who is going to see you at night in a dark PFD and your not with it enough to yell or blow the whistle?

I use an old mil surp radio pouch, and have it fixed to the left side of PFD. I can squeeze the mike button aka PTT, without issue while it is in the case. As it has external MOLLE loops, I also have a small 3 inch knife in its sheath strapped to it as well.  Both are out of my way when I am paddling, and both are with me at all times, under the radio is a pocket I keep the marine whistle tied off to.  Opposite side pocket has a SS Gerber multitool.

Much good info has been posted here, but I would like to add a few more tidbits.

All marine radios - mounted or handheld are pre-programmed with all the approved channels in them. CAVEAT: after you charge the battery or mount it on the boat, program it for your use, i.e., set it for USA, Canada, or International depending on where you live and go boating. If you don't, channels may not be on the correct frequency of the same number.
If you have GPS, AIS built in, so much the better. Any reliable brand of radio is better than no radio.
Learn the proper procedures - it is NOT CB radio.
Leave it set to monitor Channel 16 either solely or in a dual or triple watch mode.  This IS the international distress and calling channel. After you make contact, switch to a "working" channel. There is a list in the radio manual of what is approved for your use: com'l, non com'l, USCG only, bridges, etc.

PFD's - Inflatable pfd's come in many colors when all buttoned up ready for use, but they are either yellow or orange when inflated.
If you can't read the USCG-required labeling inside a pfd, it's time to retire that unit and get a new one.
If you think it's easy to put on a pfd in the water, try it some time especially when the water is cold and choppy with swells.

ABOVE ALL ELSE - Take an approved boating safety course from the USCG Auxiliary, US Power Squadron, or Boat US. Even the "old salts" I have taught all said they learned worthwhile stuff.

There is much more to be aware of, just ask.
