Strange Maritime Phenomenon and Anomalies



In this video we discuss the often strange phenomenon and anomalies that happen at sea. Unfortunately I don’t have a lot of video to show you, so we have to conceptionally describe how and why these things happen.

I've had St Elmo's fire visit me several times over the years while flying a Cessna 206!
Free surface effect, a new one for me, will watch for it next time I come alongside my friend's 60 SV.

Always an interesting video, thanks Tim.

In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. The principle is named after Daniel Bernoulli, a swiss mathemetician, who published it in 1738 in his book Hydrodynamics.

Simplified, the water is pushed away from the space between two vessels or a vessel and a stationary vessel or land bank. Water gives way to solids; water rather is wishy-washy. 😆

Luv your vids!

Fascinating phenomena, Tim! I've known about the science, but had never really thought about how boats/ships might be uniquely affected, except, as a sailor, I knew about St Elmo's Fire. You asked about other experiences – A similar phenomenon I've experienced on land is ball lightning. It , too, is a form of lightning caused by heavily ionized air, but usually during a bad thunderstorm. My family was in a lakeside cottage years ago, and the storm was bad enough that I could feel the electricity on my scalp & in my hair. The telephone kept "dinging", and crackling, blue electric streamers were coming off wall switches (until they melted). Our electric oven door blew open at one point, when suddenly a 3-foot ball of electricity came out of the fireplace into the main room to add to the scary experience. It appeared almost alive, the air currents moving it a short distance into the room. It looked like a miniature 4th of July firework piece with tiny bits lighting up and going out. I don't remember how it left, but I think it just fizzled out. Most of what I remember are snatches of pictures, sounds, and emotions from that thoroughly unnerving evening's experience many years ago.

So you talk about wood sucking oxygen out of the air in confined spaces, the same thing actually happens/has happened in underground mines that are cribbed with timber. When someone not competent in underground mining goes into one of these mines with no proper ventilation or air supply in place, they end up passing out and if not recovered on time will die.

As a retired paramedic/flight medic, with extensive training in confined space, as well as technical rescue, I am extremely surprised to learn of the hypoxic deaths in the industry. I can understand going back into the 70s and before of the danger. But going forward I would have expected that the training of crews and the ability to not only react but provide emergent care for them until rescue/coasties arrive and take over care. I am the FNG here who stumbled across both of you channels and enjoy them very, very much… and have a million questions that I will ask in time to come. But thank you for such informative, and for me relaxing channel with wonderful content that is truly wonderful, please keep up the amazing content. Please be safe in your adventures. Much love n prayers from upstate NY.🙏💜

I was a pilot most of my life, and we would get st elmos on the props. On time it was so much that the st elmos on the props made a ring. It would change shape and color as we change the pitch and RPM of the prop. It lasted for a good 20 minutes, so much that our radios were total static and Everyone in the back was scared shitless until I explained it to them.

Brilliant. Thanks for the unique lesson. Ahoy!

excellent video thank you tim

Great video and thank you Tim . St. Elmo's fire also occurs to the propellers on aircraft or on jet liners penetrating a charged cloud layer. It can be especially bright around the heated forward windscreens on jets. These have a very thin gold foil screen inside that is the heating element sandwiched between two thick glass panels . The outside circumference of the windscreen will glow or the energy bolt(s) will work around to nest on the outer rims of the window. Note to Self. Don't ever, ever reach out and touch the GD window again when St. Elmo's is occurring. That was really stupid! Stupid!💥

OOORRGH OOORGH you hit that sooo hard OOOORGHHH! That is hilarious Tim, I remember hearing it awhile ago when I first watched this video, but could not find it again. Thanks for the smiles man!

I caught a giant squid (around 60' long) between the Bahamas and Cuba in a trench at around 1,500'down. I wasn't fishing for it- as a matter of fact at that point I thought they were a myth- but I caught something, began to pull it up, and a massive bite nearly broke the rod. I fought that beast for a long, long time… When I got it to the surface the captain got a gun; he said sometimes before you get a chance to cut the line they'll grab the transom etc. He said when he was a longline sword fisherman they'd squid come up at night to the surface (where the swords feed) and grab a huge swordfish and just pull it right down. Anyway, seeing that massive silhouette of the squid behind the boat was wild- I told friends back up in Chicago about the experience, and they thought I was just making it up because, "there's no such thing as giant squid". Then in like 2004 I see an article in some online paper about how some scientist 'just discovered a giant squid, which proves they're real'. Yeah I beat that by 13 years, and the captains knew about them even long before that! Very, very powerful creatures; beautiful, but just immense.

Love you're videos. Keep 'em commin.
Bernoulli's principle of lift. I was a pilot and an old-time New England sailor. It’s easy. Your explanations are good however, when siding up to a solid wall, like on the East River, it’s properly called “bank suction." And the bigger the screw, the worse the phenomenon.

Here’s something that you can help me out with. I forgot the name of the phenomenon when a vessel gets dragged along in another’s prop wash. I’d demonstrated both bank suction and this other phenomenon to my, then girlfriend and now, wife. I was crossing Long Island Sound from Norwalk to Huntington. There was an eastbound tug whose wake I crossed at about 80 yards astern of. I was sailing my Catalina 320 MK IV, shoal draft winged keel. As I crossed the tugs wake, my vessel immediately heeled 15°+ to starboard. It scared the crap outta’ my lady. I just cannot for the like of me remember what they call it.

LOST CAUSE

Man I thought you was going to tell us what happened to flight 19.

Mike Willis

The Draft Suction you talked about is called the Bernoulli Effect, or Bernoulli Principle. The water between the two ships speeds up as they get close to each other. Making the water pressure drop between the hulls. the faster water moves in a confined space the lower the pressure becomes. The water pressure on the outboard side of the ships remains the same. The outside pressure is higher so it pushes the ships together

FireEscape

Still over a year behind but working my way through your videos. Several of the phenomenon you mention should be familiar to firefighters as well as mariners. Rookie drivers occasionally learn the hard way that a full water tank or an empty one is pretty stable but a half full tank can be deadly. Today's trucks are much better baffled than in 'the good old days' so we don't crash as often. Two or three bodies in a drained septic tank wasn't too unusual before we got a better understanding of confined space. It looks like such a short drop that you could just jump down and lift out the first victim, but you become the second. Thanks for the content, it will make winter more palatable.

Great explanation – thank you. I am a retired Engineer who is learning to sail. Your explanation works very well for me.

Jim Serhant

Excellent video, Capt. I’m sorry for the loss of your 3 colleagues. Not being an airline pilot, I can only tell you what I’ve heard from pilot friends in the past. They’ve said “St. Elmo’s fire” would light up their windscreens with a purplish glow. Stay safe.

I had confined space training several times over my career, and part of the training information was that on average there would be one victim and two supposed rescuers pasted out in the space, before someone clued in not to go in to rescue those people. Also heavier than air gases can displace the air/oxygen in the spaces causing the same issues. Loved this video.

Very interesting and quite informative!!!

Thanks

What a great segment, all very interesting!

Awesome

I found your channel a few weeks ago while doing research about Tugboats. I'm a artist who was comitioned to paint a boat like yours for another captain. A present from his older sister.
Being from Wyoming I know nothing about the sea, let alone ships and tugs. I so enjoying your channel introducing me into this world of yours. I did live on the Great Lakes, my big brothers sailed of ore carriers. So I was intrigued with their stories.
Thank you for what you do, its so interesting.
