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.

Thank you for watching Chris. I wish I could help you, but that one has me stumped. CUOTO

Interesting, I am a scuba diver, in Charleston SC I was diving the Cooper River, a working river. The dive master gave me a hammer and steel rebar told me if I hear a large ship coming up or down the channel to conserve air, get on bottom,drive rebar into river bottom and tie myself down. Well guess what a large barge came. I was in around 20ft maybe less of water. I felt the suction. I always thought it was the propellers but The suction well before, I think now it wAs the Venturi effect on the bottom. Also it was black water so no visibility. Thanks for video, always wander what happened, it did scare me, have not dive the Cooper since.

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.

[@debbieknowlton9794]

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.

Another great one! For the ballasting issue - RoRo Cougar Ace was reballasting to flush tanks while approaching US NW coast in 2006. Something got screwed up and she ended up with a 60 degree list and couldn't recover. Another fun fact, the ocean eats a car carrier about every two years or so.

[@dickdaley9059]

We have the Golden Ray laying on the bottom port side down in Brunswick, GA since last Sept. It lost stability coming out of port with 4200 vehicles aboard and a harbor pilot in command. He decided to beach the vessel to get it out of the channel when the port list was beyond recovery. The public is trying to understand how this could happen. Maybe it was a reballasting failure as you described...?

[@jonathanleonard1152]

Your drawings and conceptual talk are very good for the use here. Regarding invasive species, when I was young, I was always inspected and had to show a clean bottom every time I exited the head. Regular lightning can have two parts. The negative change comes from clouds (or cloud to cloud). There can be a positive part that can be seen as lightning in super slow motion videography, this comes up from the ground or a tree or ships mast.

Very Informative Tim, The section on Confined Spaces is paramount to Marine Safety. Your chain locker example was very chilling! Explains the concept of never entering a confined space to assist a man down without the proper safety preparations and equipment. Entering confined spaces in today's marine industry is very strict and controlled. Precautions include: risk assessments, testing by Marine Chemists, Safe to Enter Permits, Work Permits, certified entry equipment, adequate training for all team members and a comprehensive Rescue Plan.

[@LeeB48]

Great topics. On the waterway I used to work at we would refer to channel suction as "bank" suction. There was always the chance if you were not near the center of the channel in the more narrow spots the vessel could be drawn into the bank if you had a little too much way on. A good friend of mine who was a pilot, would love to do a little showboating and maneuver through a rather tight turn to port by using starboard rudder. What he would do his hug the starboard side of the channel going into the turn at around 10 knots, as the vessel entered the turn he would wait for the bank suction to start to pull the stern towards the bank. As the stern moved towards the bank he would check it with starboard rudder, just using enough starboard rudder to allow the bow to swing to the port, thereby making the turn to port using starboard rudder. He would always make sure that the quartermaster understood his order very clearly before he attempted the turn. All the while really enjoying the stir it would create with some of the bridge staff.

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.

Something I learned while inspecting vessels in New Haven, USCG Captain of the Port. Certain types of manure used to be transported (as everything was back then) by ship … well in dry form it weighs a lot less, but once water (at sea) hit it, it not only became heavier, but the process of fermentation began again, and one of the by products is methane gas . . . and as the stuff was stored below decks in bundles you can see what could (and did) happen, methane began to build up below decks and the first time someone came below at night with a lantern . . . BOOOOM! Several ships were destroyed in this manner before it was discovered what was happening. After that the bundles of manure where always stamped with the term S.H.I.T on them which meant to the sailors to “Ship High In Transit”. In other words high enough off the lower decks so that any water that came into the hold would not touch this volatile cargo and start the production of methane.

@timbatsea as a airline pilot we regularly encounter saint elmos fire probably once a month or so. It will light up our entire windscreen when we are flying through weather it will generally stay on the window for a good ten minutes or so. It’s pretty impressive. I’ve also thought that squatting was also associated with the vessel sinking into the trough of its bow wave? I’ve noticed the the draft of my 38’ sailboat probably increases about a foot when I approach hull speed.

[@TimBatSea]

Thank you for watching Lars. Very cool! I wish I had video of that!

[@larsvihlen2185]

TimBatSea I’d have to imagine that some one could survive In a atmosphere of less than 19.5% O2 at sea level. I’ve attended a FAA sponsored mobile high altitude simulator where they displace the oxygen with nitrogen to equal the partial pressure of oxygen at 25,000 ft. The simulator is held at sealevel the oxygen concentration gets down to 7.8%. Now we only had about 3-5 min time of useful conscious. Interesting thing is once you go on 100% O2 with the quick don mask in about one breath you immediately regain all color vision, regain full field of view and get back to thinking. The cabin pressure in airliners is typically 8000’ and below which is equivalent of 15.75% oxygen at sealevel. It’s allowed to be upwards of 10000’ which is equivalent to 14.6% oxygen at sealevel. Unpressurized airplanes are allowed to cruise at 12,500’ for unlimited periods of time and up to 14,000’ for less than 30 min 12.8% and 11.4% oxygen at sealevel respectively.

On the Great Lakes there is an atmospheric phenomena called Fata Morgana. It is a mirage that seem to happen when the water is cold and the air is hot. I mainly notice it with the large bulk freighters that run north and south on lake Michigan. I grew up with it so don't pay too much attention but it can on occasion confuse right of way situations, never a good thing with a fast ship coming toward you.

Great insight to the mariners trade. Not boring, not to long, in fact i wish you had more "sea stories" to relate. imagine being a "stoker" on an early steam ship. But then i have always been fascinated with the old sailing ship stories. Read every book on the subject i could find. When ships were made of wood and men of steel. i always thought "rounding the Horn" on a square rigger was something i would have liked to do. i mean actually working the ship. Climbing the rigging to bring in or add sail and all the daily mundane tasks they had to do. Tho i would want modern clothing & gear. They did that stuff barefoot in the winter, wet and freezing. i am to old and soft now for that. Just like 40 some years ago i drove trucks without power steering and no A/C and thought nothing of it. Actually had a ball. Now, no way, no A/C, no go. and i can't remember the last time i drove a truck with no power steering.

Another great Video, Captain. I would like to make a motion that you continue on with your most excellent way of explaining maritime phenomena! You are accurate and easy to listen to. re: St. Elmo's fire, ... ... in the 1960s I lived in northeast Brazil helping fishermen start up a cooperative.. Before landing there, I thought, "Must ask about St. Elmo's fire". On several nights the fishermen told me about the 'Fire Potato' (Batata de Fogo), a small blue fireball that at night flew slowly above the water , circling around at random, willy nilly, with a twitchy uncertain course over boats that were anchored far offshore, trolling, or fishing the reefs. If it passed over a vessel then someone on that sailboat would die within two weeks; they cited several cases. They never described this blue fireball attached to their sailboats, they all fished under sail... so mast, boom, one sail. The fireball was free and wandered slowly at will. I never saw it. (Happy to be a subscriber, I wouldn't miss an episode.)

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

[@TheByard]

Tim You've stirred my brain again and I like that, don't won't the grey matter going soft. My father was building a slaughter house for Wall's Pork Sausages in London and some Saturdays he would take me as a school boy into work with him. This Saturday he told me to stay clear of the truck park, driver training was taking place. Me being curious crept over to the fence and spoke with an instructor, he was training driver to handle Live Loads. The pig carcass was hung from rails in the roof of the truck and would swing when cornering and braking. Just like your tray of water. I spent most of my working life in an Enclosed Space and I'm trained in Tunnel Rescue. Tunnel Boring Machine's rust, ground types will consume oxygen, some construction methods will also consume oxygen and of course the danger of fire. Just to add a bit more excitement some tunnels were constructed using compressed air to keep ground water out. So we had a higher concentrate of oxygen. In the old days miners used canaries in cages, they would fall over at a lower concentrate to humans, so if the bird toppled the guys got out quick. The squat effect: Several years back a cruise ship was built somewhere in the Baltic and needed to use the Storbaelt Channel between the Danish island of Zeeland and Fyn, But a suspension bridge had been built. So the ship was equipped with a telescopic mast and maybe funnel top that would lower. Calculations were done on air draft, tide and bridge clearance that all would be OK But as to be on the safe side the captain ordered full throttle so the ship would squat and gain extra clearance.

Thank you for watching Christoffer. I have reached out to Chief Makoi a few times (I am a huge fan), but he is a busy guy and his channel (rightfully so) is massive! I'm sure he never sees or has time to respond to me. I have tried to contact him on other platforms as well, but have not been successful. If you get through to him, please let him know that I am want to contact him.

Chief Makoi has a great channel. Sometimes he has a livestream on his 2nd channel 'Pep talk with Chief Makoi' where he talks with the viewers. I've got a couple replays from him on the premiere of his videos in the livechat on his main channel. But now when he is out at sea it's difficult with internet access.

Hey Tim I remember when I was a kid the Qe 2 went aground off the vineyard like you mentioned. It was towed to Boston Harbor at Dry-dock that is right on the other side of black falcon pier where the cruise ships come in. It was placed in a berth for repairs. I have pics of her from when my parents took them coming home from a trip. That ship was massive. That area housed some pretty good size war ships for ww2. They also have 2 buildings where they made tanks during that era. It's all retail now. Rebook has rented a large portion of the area for sports equip testing. Oh btw the mug is shipped🙏 And hope this one comes in one piece😄 Stay safe Boston is getting the crap weather now.

Thanks for the interesting talk. I was particularly interested in the parton the speed of water. In the early seventies there was an unfortunate event in the British Navy involving a minesweeper call HMS Fittleton which brought about "the Fittleton Effect" I am sure if you Google that you will be able toread all about it. Basically it involved refueling at sea. The minsweeper was being refueled by a frigate(much larger ship) The minsweeper got too far ahead and swung round into the path of the frigate. the out come was not good and there was considerable loss of life. Many lessons were learnt. I am sure you will find it intersting.

Other phenomena was sailing in a race in the fog and as the daylight came up all the boats around us in the fog was upside down. I also worked on a TV transmitting tower and was working on a microwave dish a 100 ft level at night and in a snowstorm and watched the tower glow green and an arc flashed off. There was no big bang. but the bolt knocked the operator on his ass in the transmitting building.

In this case, on a barge sitting at the dock a guy want down the hatch and was soon overcome and fell off the ladder landing in the bottom.

Have you ever heard the sirens? I was sailing with my Uncle a long time ago, before GPS. I was on the night watch. We had hove to because we weren't really sure where we were in the dark and needed to enter an inlet in the morning. Late that night I began to hear singing and music, like people were partying on the beach. I looked at each stay to see if anything was whistling but could not find anything. I could hear the singing very clearly and I worried we had drifted too close to shore, but I saw no lights so I sat listening for a long time. The next morning when we finally coaxed our position out of the LORAN, we were 5 miles offshore from the inlet. I told my uncle about the singing and he just laughed..

You can see the overflowing ballast scenario on Deadliest Catch where they keep the tanks constantly pumping and overflowing like you said to keep the tank pressed up to eliminate free surface and also continue a fresh supply of water to the crabs.

Thank you for watching John. Yes, our tugs are all twin screw. And yes, I should have talked about prop-walk because it seems to come up quite often. The green flash has been mentioned in comments below. I had said that I am not sold on it's validity, but after further consideration and watching what people are calling a green flash, then yes. I have seen that many times. It's just not (well at least in my experience) the Flash you see in movies and more of a dim fading afterglow that looses other colors before loosing it's green. Now I know that millions claim to have seen the Flash, but I have spent the better part of my life on the water and watched countless sunsets and I am not a believer although I want to be. (And perhaps I was hoping for something bigger than it was...... I think my wife said that)lol

[@Mrsnichols1965]

The odd effect that happens with squat in a relatively small waterway is that it'll pull the water off the beach as a result. In Tolchester, before they dredged the channel years ago, if a ship with deep draught went through, just before it was directly abeam the water would start draining off the beach. Water level would drop by about a foot or two. The result was a bad sort of erosion, and they slowed the channel speed limit to try and mitigate the damage. As kids, we always thought it was pretty cool. Once the channel was dredged in the 80's (I think) that effect became lesser, as did the wakes, which smoothed out quite a bit once the depth could dissipate the energy. Neat stuff unless you are a land owner, lol

[@TimBatSea]

Thank you for watching. We experience the same thing. When a barge is pumping off in a tight channel, we try to let the tankermen know when I ship is approaching. They have been know to suck a barge off the dock enough to break the hose.

[@donaldkearney3932]

Re draft suction: Since air, like water, is a fluid, this concept is a common problem for people hauling travel trailers at highway speeds. A passing trailer truck first pushes you away from it because of the "bow wave" of air pressure when the truck approaches your trailer. You have to steer slightly to the left to counteract this force. When the truck's trailer has caught up to your's, the pressure turns into a strong suction force and you have to steer right (sometimes forcefully) to maintain control of your trailer and prevent it from being sucked into the side of the truck's trailer or create violent swaying which could lead to an accident. Stock car racers use this concept strategically by pulling up to the rear bumper of another race car (hopefully a team-mate's) and locking onto the suction from the airflow of the car ahead. This is called "drafting" and can save huge amounts of fuel in a long race -- maybe enough to avoid a last-lap pit stop.

Confined spaces the probably the biggest single killer of crews, we all know about it, yet still sadly it goes on. An inland port near to me had a tragic case that involved a wood pulp cargo which had taken the oxygen out of the hold access trunking killing one of the crew who had entered it to get a broom. I had a "reverse" stowaway case! Sailed from Dagenham which is on the River Thames in the early hours of the morning. Arrived up on the dredge area later that morning. Loading and we could hear noises coming from on top of the wheelhouse. Sent the deckhand up to investigate who found a young lad up there. Seems he had managed to get on board un-noticed whilst we were discharging. He had decided that London wasn't for him, he had actually been a refugee and wanted to get back to Europe. Well he didn't get too far as we were loading for Dagenham again but I certainly had to do a bit of explaining to our office when I called in that morning.

@@TimBatSea Work Permits (safe for men) are a critical aspect for ships and tugs. Unfortunately, many mariners do not understand the hazards of not using their Companies Safety Management System Permits. Another problem is that many SMS's simple say that the company does not permit entry into confined spaces...so they have little to no training on the hazards and some have no Entry Permits in the SMS. The reality is that there is no tug or ship where people don't have to go into a void space or cofferdam at some point. Permits save lives!

I spent ten years at a medium size shipyard in San Francisco Bay; lots of tugs, ferries, barges, yachts, LST's, up to a 378' Coast Guard cutter. Anytime a "foreign" vessel (out of the area) came to us we had to pump out the bilges and dispose of the bilge water to a treatment facility. Also, without fail every open confined space had to be certified by a chemist every morning before anyone could go in. Finally, the welders had a hard and fast rule they had to follow. If they were using an acetylene torch in a confined space, at the end of his shift he had to shut off the supply lines at the manifolds on deck, then remove his torch from the hoses, then he had to pull the hoses all the way up to the deck and coil them up. Twice in the ten years welders forgot, and the Chemists stopped them from entering the area due to the gas concentrations. Both of the welders were fired instantly. Towards the end they were phasing out gas torches in favor of plasma cutters, which only used electricity and pressurized air to work.

A small tanker split in the middle as it was pulling away from the dock in Port Jefferson harbor in 1972. The ship was only 9 months old and had gone through a couple of storms at sea. Fortunately it had unloaded its fuel load at the depot. It ended up in a "V", with stern and the bow on the bottom in 32 feet of water. I think usually things like this happen if not carefully balancing the loading/unloading of cargo. This ship was empty. One of my favorite quotes "There is always the unexpected" (Movie Bridge on the River Kwai}

[@seanwaite4755]

The vessel was the Martha R. Ingram which was actually a ITB (integrated tug barge) Were the tug was basically a engine pod coupled to the barge as one unit (then a modern technique to reduce Manning requirements, a different topic) I grew up in Port Jefferson and remembered going to the harbor on a freezing January day to see her broken and I saw them tow the two pieces out with Ice chunks floating across the harbor. I was told and it even came up as a case study in a stability class in college (URI Commercial Fisheries and Marine Technology) that it broke do to loading ballast fore and aft, leaving the middle empty, like Tim talks about as Hogging. Though I just read a Coast Guard Marine causality report that mentioned her being ballasted to be able to turn around in the shallow water but doesn't say how or what tanks were loaded. The report blamed the kind of steel ABS allowed the hull to be made of being brittle and the lack of crack arrestors welded in the hull. They believe a deck crack from where the cargo booms were traveled splitting her in two. In my opinion Most likely from Hogging from the ballast. If that was the case they're error probably saved their lives and she didn't crack in two offshore in bad weather.

Your explanation of ‘squat’ makes a certain amount of sense especially with unpowered barges but I was under the impression that in a power vessel in shallow water squat was caused by the action of the screws pulling water from under the vessel. If you remember the ferry disaster in the English Channel (Spirit of Free Enterprise?.. or something like that) a crewman failed to close the bow doors after loading, the bridge crew accelerated hard, the bow squatted and scooped up half the North Sea and the free surface effect did the rest. But in that case I think the squat was caused by the screws pulling water from under the ferry. Bernoulli’s law relates to pressure dropping as a gas or liquid accelerates ( if memory serves).

Thank you for watching Peter. I am not thinking the bow dropping was an effect of ground induced squat, but I could be wrong.

Tired strained eyes wanting to see and not blinking for so long that they end up seeing something that isn't there.

Tim, you'll just have to come down to the Gulf Coast of Florida. Perhaps it's the lower humidity of February, or our elevation (an upper floor). I credit it to clear skies and a completely unobstructed horizon that I have seen the Green Flash on multiple occasions over the years. I've twice seen weaker, less green flashes on the Pacific when the weather was less clear. It seems to be the momentary shallow angle refraction of sunlight off of sea.

@timbatsea Imagine if you will a 900 foot+aircraft carrier and a 650 foot oiler. Assume draft for both at around 35 feet. Now picture them steaming side-by-side at 17 knots with 150-200 feet of separation while connected together with 2 or 3 1" wire ropes carrying 8" rubber hoses transferring JP-5 (Jet A) at around 60 PSI. Also picture NO automation for station keeping, and relying on manual control at the helm and in the engineering spaces. For fun, add a 2nd ship off of the OTHER side of the oiler doing the same thing, for a total of 3 ships. There is your venturi effect. Surface effect comes in with the 7.5 Million gallons of cargo Marine Diesel and JP-5 that the oiler is carrying. Just plain wallowing around comes with the additional 1000 tons of ordnance, food and supplies you are carrying as cargo. Should probably also mention that throttle response on the oiler is typical for a twin-screw deep-draft ship with a 600-PSI steam plant...you can pretty much smoke a cigarette while transitioning from full ahead to full astern. Even with 16,000 HP per shaft, nothing happens quickly. You have just imagined a day in the life of a US Navy Replenishment Oiler. This is called an "Underway Replenishment" and is used for transferring fuel as well as palletized ordnance, food, and supplies. We sometimes did this several times per day (or night), in sea states that you wouldn't consider it possible at, and with everything from the smallest allied frigate to our largest supercarriers. For added spice, remember that the helmsmen on all three ships during this whole mess are quite possibly young enough that he/she cannot even go legally have a beer when they get back to port...
