Re: Ever seen a submarine on sonar?

I'm doubting anyone is going to see a sub on sonar from your sailboat sonar unless you luck out.

If it were that easy, we wouldn't have P3 aircraft etc dropping buoys simply to "listen" for subs

Re: Ever seen a submarine on sonar?

While we were doing man overboard training, some months ago, near the Isle of Wight, we had to abandon "Steve" the Bucket Fender man in the water because a BIG black submarine decided to surface and move in our direction, the escorting police and pilot boats were waiting somewhat at the wrong place and we decided to abort and move and give them the right of way (plus they had torpedoes ) and an exclusion zone around them.

We did go back for poor "Steve" the Bucket Fender man, but by the time we recovered him from the water he was very cold and not moving.
We buried him in the Cockpit locker under lengths of rope with full sailing honours.

Re: Ever seen a submarine on sonar?

A little off topic, but I wonder how many serving or retired Submariners are on Cruisers Forum? I see Catapault, SailShabby, jlcnuke, sailorboy1 & Zulu40.
There is at least one Sailing Vlog on YouTube produced by a retired Submariner from the USN, "Sailing Zingaro".
As an ex "O" boat sailor of 20 years & now retired for longer than I was in, I offer a warm welcome to anyone who has earnt their Dolphins regardless of race, colour, Country served etc. If any of u guys (& Women) are ever on the East coast of Australia please drop me a line as would love to catch up. Sundowners onboard my boat any time of the day or night
I am currently putting together sailing days for Veterans suffering from PTSD & Cancer survivors (Victims).
Cheers all,

Re: Ever seen a submarine on sonar?

It's the most amazing thing, I NEVER considered that I had to pay attention to submarines. Ships? as soon as they are in view I keep them under watch to see where they are going and not find myself in their path, sailboats, any other type of vessel no matter what type or shape.
But seeing a SUB appear where there was NOTHING really took the cake.
And no, our "sonar" did not beep beep ... was interesting and made for a nice few pics, but also a warning to keep a look out for the harbourmaster announcements which we obviously missed.

It is policy except in rare circumstances never to reveal the location of nuclear submarines, which is just about the entire USN submersible fleet composition. I think I can remember a USN sub that was involved in an accident which initially the USN wouldnt admit to, but came clean when the boat was dry docked in Virginia for extensive repairs and her story came out.

By way of explanation just as a footnote, the USN did lease a small Swedish conventional submarine of the Gotland-class and her crew for at least 12 months. That vessel was the basis of the RAN Collins boats. But for the USN conventional boats do not suit their force constitution or deployment and the usage was purely 'investigative' and experimental.

Re: Ever seen a submarine on sonar?

In 1990’s there was a fishing trawler sunk in Scotland when it’s nets got in a tangle with an English nuclear submarine that passed underneath where they were fishing. I do remember that the Navy said no way and it kind of blew up on their faces, I believe the crew of the trawler was lost if I remember right.


Damn, i'm gonna have to google that now.

Fishing trawler was the "Antares" and 4 man crew was lost in 1990
The submarine was : Royal Navy submarine HMS Trenchant. A hunter/killer



Story of the incident http://britishseafishing.co.uk/the-s...of-fv-antares/

We had a fleet of Lockheed Orions too, notable for their lengthened tail housing the magnetic anomaly detector (MAD). When their age overtook them despite their sterling service they are all due to be scrapped by 2019 and replaced by Boeing P-8 Poseidons and MQ-4C Tritons.

plus MAD has strong countermeasures these days, at least for us. And hydrophone technology has overwhelmingly surpassed mere buoys. Despite this the Orion remains one of my favourite aircraft.

Re: Ever seen a submarine on sonar?

Once about 7 hours out of the Chesapeake Bay I began to hear a noise that very quickly grew loader and loader. I was under sail and had no machinery running at the time. Of course I looked all the horizon and no vessel or aircraft could be seen. At one point the sound peaked in intensity and then just as it arrived it faded away. Given all the navel activity in the area form the large navy bases in Norfolk Va I assume what I was hearing was the prop wash from a submerged vessel as it passed near or even under my hull. I was offshore and in deep water so I did not have my depth sounder on.
I do however own a commercial fishing vessel in Alaska and I do indeed see whales on my sonar. This is nothing I desire to happen because I know Orca will feed upon the salmon I’m catching and in doing so will destroy my expensive gear.
Today there are many high quality depth sounders on the market. They are measured in both output watts and the frequency of the signal. Frequency’s can range from 35 kHz to 200. Your transducer must match this. Many units use duel frequency because the 200 kHz will give better detail at shallow depth but cannot reach the bottom much beyond 60 fathoms so when you range to a deeper setting the unit will then switch to the more common 50 kHz and there you can often get readings several hundred fathoms.
I like Furuno and it’s about all I buy in terms of radar, plotters and sounders. But beware.....Furuno VHF radios are not what one would expect from the reputable name of Furuno. Better to buy Icom, Standard, Sailor or even Kenwood but we are not talking radios that’s another subject all together.
I have a friend who just buys Garmin and B&G. Looking at B&G it seems to be just as good as North Star and it’s made in America I think. I would consider this brand too.

Re: Ever seen a submarine on sonar?

Last December we were sailing down the Baja nearing Cabo. Now we had run out of fuel the previous day and eventually having made our way back inshore, which had provided nothing but light fluky winds, enjoyed a great slay ride on the night land wind for about 8 hours until we had rounded the heal and in the lee of the baja peninsula we bimbled along at 2 to 4 knots on a calm and tranquil sea.

Now the light winds of the previous day had had the sails slating and banging so sleep had been impossible. Then the 30 knots as we closed with the land made it imperative I stayed awake even as the Admiral steered. We had 3 independent electronic charts and non of them were good, at times down the coast we had anchored a mile and a half inland?

That meant that the admiral and I definately where on the tired side as we approached Cabo. So we had a quick discussion and had a vote which meant that I stayed awake while she slept.

After being in very low population areas for so long the miroriod of lights as we approached Cabo with its hotels and condos was a very different landfall. As we neared the famous rock formations that form the Western edge of the bay at Cabo I was aware of a line of white lights that marked the way to the harbour. These lights were bright and seemed to be very close to the water if not under it. In my 40 years of navigation I had never seen the like. I was unsure which side to steer and came to the reasoned conclusion they must be an aid for the cruise ships that infest this part of the world. I passed several and thought that if they were for cruise ships they must be Ok for me as well. That was until these Navigation lights started to overtake us.

I did consider Aliens or that my mind was playing tricks, so took it on myself to call the Admiral from her slumbers. Lets just say she was less than helpful but did confirm that I was not seeing things. As we reached the last outcrop that allowed us to enter the bay I caught an outline 30 ft away. I called out Hola Amigo and received an Hola in reply. Guess the Mexican Navy had some semi submersible sleds out for a night ride.http://www.cruisersforum.com/forums/...lies/peace.gif
