I have several vintage oval types that I like to collect..... especially the really old ones that have the strap attach point all the way to the rear of the skirt (like the Voit B4 used by LLoyd Bridges) When you push these up on the top of you head like Mike Nelson used to always do, it looks like you're wearing a top hat it really freaks out the tech divers to see that However, the one that I use the most (even with modern gear is my Nemrod Max-Vue) It is the Mother of all the old fish tank wrap arounds. I've never seen a larger one. This thing is like strapping your living room picture window to the front of your face. After wearing this thing once.....any other mask will give you claustrophobia.

>i was just wondering if the mask were on sale in US < You can order goods internationally using a credit card. I live in the UK and routinely order things online from the USA and continental Europe. They may take a little while to arrive, but they always do eventually, so give "Au Vieux Plongeur" a go. Otherwise try and find, say, a Beuchat dealer in the USA. Here's a clickable map of the USA where you can locate one: www.beuchatdiving.com/map3.htmThey probably won't stock the compensator-less mask, but you can ask them to order one for you. David

Just noticed something on the Miss Vintage Scuba Photo Gallery.....the girl Molly is not wearing Vikings as the text says....those are really the Voit SkinDiver model in the two tone black\blue. Surely I'm not the first to catch that mistake..... Buzz

Buzz Soooooooooooo, Buz.......................none of my business..............................but, just how many times did you have to view that image to notice THAT! You're looking kind of closely, aren't you ? Good golly, Miss Molly, you're in the wrong fin!

Yes, those open toes give the game away... In the US Divers pictures, she's wearing Otarie fins. Very comfortable, because they fit in such a way that the toes tend not to protrude through the end of the foot pockets. The fins have more powerful and heavy blades than they look.
The Japanese model is holding what look like Gull open-heel Power Emden fins, which are currently available in a choice of eight different colours: Black, Yellow, Blue, Pink, Green, Purple, White and Teal. Who says only plastic fins can come in a wide variety of colours?

Well, I found a few more of my photos of the Voit Viking fins that I modified. I'll add this photo, as it shows the fin more closely. You can see from the ragged edge of the heel cutouts that I have actually cut these out, and that it is not the way the fin came to me. Photo Copyright 2005, John C. Ratliff You can also see more clearly the lines that show the water flow across the fins. I'll be putting together a separate thread on this subject soon (probably tomorrow evening) to discuss in more detail my ideas (again vintage, since they originated in the 1970s) of the scoop fin.

Makes more sense to me than split fins. Is that other guy's patent still current? They expire.

I never really understood why Voit made the Skindiver and the Viking A6. They were essentially the same size and shape aside for a modified toe-pocket. They also perform the same. The Viking has the cool Viking ship and the Skindiver has the even cooler Skindiver with speargun molded into the blade. Did anyone see the thing on the "Ten Deadliest Sharks". There were claims and a very interesting video clip that alleged speeds of up to 68 MPH for a Mako shark!!!!! Clocked speeds of over 30 MPH were also claimed!! The video showed the Mako striking at a towed lure and however fast he was going it was severely quick. I find both of those speeds to be fairly unbelievable, the energy output to push something like that through the water at 60 MPH or even 30 would be very large. How fast are the fastest nuke powered attack submarines? I find it diffucult to imagine that as I charge along propelled by 150 straining horses at close to 50 MPH that a shark could outrun my Boston Whaler. Well, if he bites a hole in it at least it won't sink and maybe he will get indigestion from the foam and find something more tasty elsewhere to snack upon. If the patent has expired then it seems that one would be free to produce simialr designs. I would settle for a modern all rubber Viking with a longer and stiffer blade. What about a "scoop kit" that could be marketed for retrofitting to someting like a Biofin or even the chunky Jetfin etc.? Buy a fin, buy the retrofit kit and then voila--scoop fin! James

Been out for 24 years but served on a nuke fast attack SSN 614 USS Greenling. this was of the 594 Permit class (which was originally the 593 Thresher class) The last 3 of the class 613 Flasher, 614 Greenling and 615 Gato were lengthened by 13 feet at the aft end of the operations compartment during construction. We were a bit slower than the 637 Sturgeon class and 688 Los Angeles class. Speeds are classified and our reply when asked was limited to "in excess of twenty knots". Your Whaler would pass us with no problem, the MK 48 torpedo will pass your whaler with no problem. Going fast just made it harder for us to hear and easier to be heard. Just a little too much rudder would cause cavitation. Our screw resembled a huge trolling motor prop but with 7 blades. The fastest sub in the water back then was the Soviet Alpha class which had a titanium hull and for a time could also go deeper than our torpedoes. Rumored to be capable of high forties

Well, if he bites a hole in it at least it won't sink and maybe he will get indigestion from the foam and find something more tasty elsewhere to snack upon... James James, that is plausible. The new issue of American Scientist has an article titled "How Tunas and Lamnid Sharks Swim: An Evolutionary Covergence" ( American Scientist, Volume 93, 2005 November-December). I picked it up to further my studies of underwater swimming. It shows that the sharks and the tunas are both somewhat warm-blooded, and use similar adaptations to swim fast. Curiously, they never talk about the actual speed in the article. But this source does: hypertextbook.com/facts/2000/IsaacKlein.shtmlThey are talking about tuna going 60-80 km/hour, or 35 to 50 mph. I would say that this is a fairly fast clip! Shorter bursts may be even faster. Remember, the tuna (or shark) doesn't have to be slowed down by contact with the surface of the water. When I entered "22 meters per second in miles per hour" into Google, here's what it spit out: 22 (meters per second) = 49.2125984 miles per hour. Wow, that's fast! If the patent has expired then it seems that one would be free to produce simialr designs. I would settle for a modern all rubber Viking with a longer and stiffer blade. What about a "scoop kit" that could be marketed for retrofitting to someting like a Biofin or even the chunky Jetfin etc.? Buy a fin, buy the retrofit kit and then voila--scoop fin! James While I would like to think this is a good idea, unfortunately it takes much too much time for most divers to try. The biofin would work, as would any flat bladed fin. But the JetFin would not, as there is too much rubber in the way. This would take cutting and drilling and pop-riveting (which I've done on my current fins), and is not something someone is likely to try to a pair of fairly expensive fins. But if you do like I do, and buy used fins which can be converted, my last pair of full-foot Plana fins were $15. John

SeaRat, when that Mako accelerated toward the lure the distance closed so fast it appeared animated and surreal. I don't know how fast they can go for a short burst of a few dozen feet vs sustained swimming for some distance but I find it scary as well as hard to believe. Mako sharks, and I knew this already, are adapted to maintain a pseudo warm blooded state allowing higher energy output even in cold water. James

What I find strangest of all is observing Dolfins swimming along with your boat in front of the stern. If you look at their fins....they are barely moving!! Even as your boat is up to full speed, they look as though they are being towed instead of swimming at that speed. If a human coud go that fast, his flippers would be going at lightening speed and cavitating like crazy. If they can go that kind of speed with no effort, I find it easy to believe that bursts of speed in the 60's mph are quite possible.

Buzz,
The dolphins you are seeing are riding your bow wave, which is why they look like they are not moving. They actually are getting a free ride. In the open ocean, away from your boat, they have to expend a bit more energy.
James,
Now I wished that I had seen that TV show. I like watching any of the televised shows on dolphin, whale or sharks swimming. I find that information interesting, and continue my study of swimming styles in the water.
John
