Ocean Ramsey

I’ve spoken to a number of people about diving with sharks, both freediving and with open and closed circuit rigs. In the photo, Ocean Ramsey, who owns One Ocean Diving in Hawaii, swims with a 20′ Great Normal Shark.  (there are complaints that calling them Great White Sharks is racist). If you’re not bleeding and if you’re not in a seal rookery where they are feeding and you’re not splashing on the surface like a dead fish or a surfer, sharks leave you alone. When you’re underwater with them, they tend to circle you to try and figure out what you are because you don’t look like a fish to them.


Yeah, like that



Copper Bottoms

One of the greatest enemies of saltwater sailors was the teredo worm. Commonly called the shipworm, the teredo worm ate through submerged wood, and could turn the hull of an oceangoing ship into a leaky sponge in less than a year.

The solution – covering the underwater hull with thin sheets of copper. It was first proposed in 1708, but the first copper-plated ship would not emerge until 1762. HMS Alarm received the first copper bottom, she was chosen because she was in such poor condition due to the teredo worm having taken a significant toll on her hull.


Recoppering the CONSTITUTION by Aiden Lassell Ripley, ca. 1965.

That trial showed copper not only poisoned the teredo, but it prevented hull marine growth, too. Coppered ships were not only proof against shipworm, they sailed faster. But other experiments in the 1760s revealed that copper, when it came in contact with iron fittings in the hull, destroyed the iron through galvanic corrosion. This problem was solved in 1783 when orders went out that copper and zinc bolts should replace iron bolts.

In early 1779 the Royal Navy ordered all ships larger than 32 guns to be coppered when they entered the dockyard.



Bullet Points:

** h/t Claudio – Pakistan’s Air Force Woes – Pakistan has problems with its 134 JF-17 jet fighters. The Russian-built RD-33 engines that power the JF-17s have been cut off from replacement engines, spare parts for maintenance, and technical assistance by the heavier sanctions imposed on Russia because of its February 2022 invasion of Ukraine. There are no legal solutions to this problem and all alternatives are being explored by Pakistan to keep their most modern jet fighters operational.

Pakistan made a huge financial investment in the JF-17 to replace 270 French Mirage fighters acquired during the late 1960s and early 70s. These are now grounded. Some of the 140 Chinese F-7 (Mig-21 clone) fighters acquired in 2002 are still operational, and the same with the 75 American F-16s acquired since the 1980s. Updating or replacing the American F-16s has been disrupted by Pakistani deceptions about its support for Islamic terror groups it was supposed to be fighting. Pakistan is still trying to revive relations with the United States but that is not going well. The only other modern fighters Pakistan has are 14 of the 72 Chinese J-10CE fighters ordered in 2022. This is the first export order for the J-10, which was developed at about the same time as the JF-17 but for use by the Chinese air forces. Pakistan considered the J-10 too much of an F-16 clone and vulnerable to retaliation for technology theft.

** (RFE/RL) Ukraine’s military on January 21 cited ongoing fighting in the east of the country after Russia claimed to capture a village in the area, while Western officials offered more help but also tested Ukrainian “resiliency” as Russia’s full-scale conflict approached its 12th month. The British Defense Ministry suggested that “overall” the war currently appeared to be “in a state of deadlock.”

The report comes with Britain poised to start training Ukrainian troops ahead of a shipment of Challenger 2 battle tanks but other NATO allies are still debating the supply of modern Western battle tanks.

The U.S. official that Reuters quoted said Washington was still not ready to provide Ukraine with any of its highly regarded Abrams tanks.

** The US Food Supply – Is the United States government or some other malicious entity behind the dozens of mysterious food processing plant fires that occurred over the past year? EcoHealth Alliance whistleblower and bioterrorism expert Dr. Andrew Huff seems to think so.

** Housekeeping – I want to thank you who come by this blog and those of you who contribute. If it wasn’t for the comments,  I wouldn’t go through the effort of doing this (without advertising income) almost every day. I’ve been accused by some in emails of being some sort of manic-depressive to do this sort of posting. That is not my problem. Neither have I ever been referred to as a narcissist.  Though I do some things very well and know that I do, blogging isn’t one of them. It’s an inexact thing. We’re up to about 60,000 page views a month (or 3/4 of a million a year) on Virtual Mirage.  So thanks again to all of you who visit. By comparison, Khloe Kardashian’s weight loss journey received 10X that many hits in a day.  The Internet is funny.

  1. Though I check this site several times a day, I generally just lurk because I really don’t have much to contribute. In response to “Housekeeping” I want to say that I am a history buff who thinks you post some of the most interesting tidbits on the internet. Good work!

  2. I think I have learned something every time I visit Virtual Mirage, either from you or the commenters. Thanks!

    Never used the modern large fins when snorkeling, it looks like it would require a different, much slower, cadence.

    Interesting article about Dr. Huff. When do things change from being a conspiracy theorist to there actually being a conspiracy? Don’t know if it is the eco terrorists, shear chance or the government but these fires certainly make people more reliant on a central gov so have the tendency to centralize power.

    • I still use the old ScubaPro Gorilla fins. They’re rigid and a lot of people don’t like them because it takes muscles to push them but they deliver superior propulsion.

  3. Ocean- Uh huh, a theory stays one until it doesn’t and one realizes it is better to be lucky than good, might end up like Timothy Treadwell when his beloved grizzly’s ate him and his girlfriend for dinner. Thing is, it is still a free enough country [barely] she can do a dangerous activity if she wants.

    Processing ‘Plant’ fires (does that make them semi-vegan?)- Congress will assemble a Commission to exonerate the CIA then seal the records for 50-70 years. This IS purposeful.

    Self-depreciation aside (I don’t believe you don’t know what you are doing for one second) this is one of THE BEST blogs I read each day, and all of us are extraordinarily grateful for your continued plugging away on it.

    COPPER BOTTOMS (no, not talking about any of the Kardashians who have sold their souls for 30 pieces of silver)- Take a look here, This incredible young man (yes, Jules, a Bristol Brit) is brilliantly restoring (actually rebuilding) the Tally Ho, a 1910 Gaff Cutter. And he seriously knows what he is doing, even sailed across the Atlantic on a 26’ Ketch. To avoid the prior boats problem with rot due to cast iron and other metals used in it’s construction, he is opting for bronze and copper fittings and fasteners. He’s up in Sequim, WA, at a rural property (his hosts), and for years (started in 2017) has been there working and employing local people and businesses for materials and skills, but mostly doing it himself (“The boat is only as good the Captain steering it”…henceforth why America is badly teetering over the abyss…but that another discussion.) Leo’s Tally Ho Blog is likely the ONLY one in the world showcasing the art and amount of work required (despite the county trying to shut him down because of one nimrod neighbor complaining, Ep 92).

    Boatbuilding is like ranching/cowboying, a dying industry at the hands of bureaucrats and nudges, however, this has reenergized the industry as thousands have become enamored with his work and passion to maintain authenticity, giving us more seasoned folks some hope that young men and woman are carrying forward the skills and effort required to do critical industries and aren’t afraid of hard work. Leo’s very well done YouTube videos are up to 144 episodes (Jan 14th), I’m at 92. As a former building restoration professional it is refreshing to see the level of skills involved as well as the progress. Take a watch, you’ll be hooked.

    • Paul, I think you made my point about me learning something from commenters. Just spent over an hour wandering around the url you posted. Will wander more tonight but right now I have outside chores to do. Thanks for posting it though, much appreciated.

      • CW over at Dailytimewaster deserves the h/t, posted ep.58 back on the 15th. This is the amazing and innovative and good stuff we should be championing in America, not a bunch of losers and talkers from the Dufus Club in DC or the lazy who think they’re owed something simply for being born.

  4. Food Plant fires.
    There may well be several different actors with different agendas. For example, some ultra wealthy people are heavily invested in agriculture. Won’t sell, on their terms? Burn them out. Serious competitor? Put them out of business. CIA, eco-terrorists, disgruntled employees, human error, or deliberate to cash in on insurance are all possibilities. I’m not a trained investigator. Don’t most investigations begin with looking at motives?

    Your blog is a must read everyday. Takes me out of my comfort zone and promotes thinking. Please don’t stop.

  5. I think the Kardashians get all those hits for the softcore content.
    It’s a remarkably loathsome family.

    – Kle.

  6. Regarding swimming in clear water with sharks around. When I was 7, I was taught that if the sharks are swimming smoothly, with their pectoral fins at a reasonably horizontal position, all things are cool. It is when the shark starts swimming in a jerky motion with the pectoral fins more down, then the shark goes from being just another fish to becoming a Teeth Person (which is the direct Micronesian translation of their word for ‘shark.’)

    Reef white tips, reef black tips, most of the other species, all follow this rule.

    The critical thing here is… CLEAR WATER. So you can see shark, shark can see you and, most importantly, shark can sense and see you and not have to take a taste to check out what this new thing in this world is. Muddy water is dangerous water.

    Of course, this was back in 1970, in the middle of the Pacific, so I am sure some PhD or other ‘expert’ will tell me that I am wrong. But in the three years living at Kwajalein, in the Marshall Islands, with pert near everyone swimming in the lagoon and snorkeling and diving being a common thing, only one jackass got bit, and that was because, yes, he FAFOd. Provoked a shark, shark exhibited jerky motion and downward pectorals, jerk continued to provoke shark, shark said in shark language, FAFO. Prevailing mood about shark bite was jackass deserved it.

  7. Ocean Ramsey has bigger huevos than I do, not to mention much better lookin’, and I’m not at all ashamed to fess up to the obvious.

  8. Agree with WSF: “Your blog[s] is a must read everyday.”
    Learn more in 5/10 minutes than I ever did in college; e.g. Copper Bottoms, Pakistan’s Air Force Woes, Ukraine’s [soi-disant] military.
    Yeah! I know: some opinion, some fact and it’s up to me to take out the threshing machine and either keep the results of my knowledge/viewpoint/research to myself or argue it out (primarilly with Beans or Paul M) in Comments.
    No question ’bout it: IMHO the best blog in “da sphere.”

    • I mostly emote..heh.

      Discourse, even agreeing to disagree while still being respectful of another’s viewpoint, is critical to understanding. That is one major factor in why I really enjoy this blog…it never gets petty and everyone commenting brings something to the table. VM is a 5-Course epic meal on a daily basis.

  9. While diving in the Gulf of Mexico, I noticed the spear fishing around the platforms was better when the sharks were around. They would circle just within vision, and the fish would congregate around the legs of the platform. I don’t know if the electromagnet field of the platform caused problems with the sharks, or they were wary of the “huge fish” they rarely encountered. I do know they made me nervous. As a diving instructor told me: “If you’re scared of a dog the size of a small shark, you should be scared of a shark the size of a small dog.”

  10. Yep, if you have a wooden boat and put it in salt water without a copper bottom or the ‘correct’ paint, you’re asking for a sponge… Funny story out of NAS JAX, senior O4 bought a 42 foot ‘yacht’, was told the ZINCs needed replacement. He went out and bought two new SINKS for the heads on the boat and wondered why he got laughed at… Airdales… sigh… And yes, I was one!

  11. A lifetime ago, when I as 18, a group of us all got scuba certification and would go from north Miami down to the Keys once every six weeks on a “Teachers’ Work Day” long weekend in our senior year of high school. We’d grab lobsters when and where legal, spearfish, and live off what we hunted.

    Sharks were there all the time, mostly lemon sharks, bulls and nurses. Saw one blacktip and a handful of hammerheads at different times. Never far enough offshore to see whitetips, or tiger sharks. We never had one go after a fish we’d speared, or us, but they’d be checking us out, trying to decide what we were. Our instructors and friends all said what Beans was saying, when their pectorals start pointing down and they kind of arch their backs, nose and tail up, it’s a good time to retreat slowly while doing your best to keep them in sight.

  12. I’m with the others that say keep up the blogging. I get a lot of information here both from you as well as many of the commenters.

  13. We saw the videos from that shark encounter off Oahu. There was a whale carcass nearby and the sharks were very well fed. Apparently, the tigers all left just before the huge white showed up. The big female white was identified as one known from South America. They get around. Personally, I have a low tolerance for sharks and won’t intentionally get in the water with them.

  14. I know 20 to 30 percent of Aircraft and one of the tracked or wheeled vehicles about every 6 months. But I was also Air Force and if you were in a squadron that had a real budget Supply would order the decks of cards that had aircraft on them. I have been retired for 19 years and it has been 27 since I was in a squadron that had a real budget but I think I still have an unopened pack from 1990.

  15. I try to keep up, and there are times I resent your output for the burden you place on me to read your post and all the comments.
    Then there are times I’m caught up and waiting impatiently for you to post next.
    This, NFO and Bunkervile with the occasional LSP are my goto’s.

  16. You all are welcome to play with the sharks as much as you desire. I prefer to mind my own business and let them mind theirs.

    Living on Guam, I snorkeled on the western and northern beaches where the sharks usually didn’t hang around. There was one deep hole that the sharks did enjoy and many of the compressed air divers enjoyed going there to play with them and to look at the float Zero on the bottom. The same guys who liked playing with the sharks would poke at the lion fish and puffers. I preferred watching the reef fish and corals.

    As a note, puffers are box shaped before being threatened and make quite a funny sight as their fins and tails work at high speed while the puffer barely moves.

    • I don’t dive much anymore, but when I did it for a living, I left the sharks alone and found that they seemed inclined to do the same. Beans has a good point about diving in obscured water. Technical dives like those can be exceptionally difficult if you don’t have a solid handle on currents. Swimming from A to B with a compass board and a swim buddy sounds easy until you have 12″ of visibility at night. Ship attacks from combat swimmers occur mainly in harbors and they’re almost always turgid, full of sewage and trash. And if there are sharks feeding on carrion or whatever, you can’t see them.

  17. Matt Hooper from Jaws: “Sharks only do three things…eat, sleep and make little sharks.” They may be docile at times, but a tiny part of their tiny brain will always say, “Eat it.” Like crocs and gators, sharks haven’t evolved much since the prehistoric dinosaur age. Your blog and the time and energy you put into it are mucho appreciado.

  18. Back in my early days of Gulf Coast Shrimping, when we’d pull the bag (closed end of the shrimp trawl) out of the water before dumping it to cull out the catch, I noticed some small fish darting in toward and away from the bag. After picking up the bag by hand, noticed the trash fish (poggie/menhaden) that poked through the net mesh were headless. Next drag prior to grabbing the bag, paid close attention to what was going on. The small fish were small sharks going after anything that was poking through the net…mostly poggie/menhaden heads. From then on, unless absolutely necessary, tried to avoid putting my hands in the water when picking up the bag.

  19. I stop by several times a day to read your posts, AND the comments. All are greatly appreciated. Sometimes I learn a lot from the comments, and almost always get a chuckle or two out them. Paul M, WSF, and I should get together. I’ll bet we’d have quite a hoot! Add LL to the mix and we might even see some drones…
