defining The Perfect Breach

[HJ]

I'm starting a new thread because of Ted's (zerog) tagline of "pursue the perfect breach," which caught my eye. Don't know who is interested, but I am intrigued by the concept of humans breaching the waterline. I never really thought about it much until Ted came on here in pursuit of this idea (I apologize if I've left out others also pursuing this). And obviously, Ted's very serious about it. I couldn't find much on the SubHuman website about it, and Googling doesn't turn up a lot, although here's a good Wikipedia entry about whales breaching:
http://en.wikipedia.org/wiki/Whale_surfacing_behaviour
If you google "the perfect breach", here is one of the entries:
http://www.fotosearch.com/DSN013/1787703

So here's my question (rather, questions), whether for Ted or anyone else...

What defines a true human-powered breach? What is the goal? Is it 100% clearance of the water surface by the entire body and anything attached? Or 40% as with whales and Whitehead (see first link above).

Is it an "all or nothing" clearance of the whole body, or can it be a "one part at a time" breach? Like the Fosbury Flop in high-jumping where parts of the body are clearing the bar while others parts are still below it? see:
http://en.wikipedia.org/wiki/Fosbury_flop

Will there be an International Association of Breaching that will set the rules? Should I be on the Rules Committee?

So what *is* The Perfect Breach?

Some things to ponder on a gray day from the Land of Thomas Jefferson...

Hi Harald,

To me it is maximizing the power of the human body through proper technique, and proper mechanics and geometry of a high performance mono, to get as far out of the water as possible. In my opinion, getting complete air is possible and I am pursuing it with a passion!

Aha. Great to hear, Ted. I predict there will breaching competitions some day, with everyone breaching, but some breaching higher. Just like High Jump in Track. Maybe a laser beam will be the pole. And the sportscasters will be gushing: "Did you see that? Perfect form and 1 meter of pure air in a tight double tuck." And I'm very good at predicting the future.

Nice one. Think I'm going to get myself a membersip to the "Y" to get my pool training in for the upcoming 2008 Breach Finals. I presume I'll need a graduated pole or laser and cameraman for all deeprblue forum competitions posted here. Will there be a w/ fins class and w.o./fins class?

In all seriousness though, sounds like alot of fun and has a potentialy competative edge to it.

As a first attempt

The Breach

Come on, my grandmother can get higher than that using her bunny slippers... just kidding... very nice!!

Hey, don't be so hard on him. He put himself on record and "set the standard". Looks to me like he actually cleared the water in a 'high jump' way. Which is why a definition is in order.

FYI, I tried a breach a la "skyhopping" in my 3-meter-deep pool with my bi-fins. Got up to my Speedos. Need a little more depth!

Of course! That's just a bait which was made using inefficient v-folding (you can see it from the video) monofin! Waiting for the result of an athlete improved by Lunocet

[monkeyhatfork]

if you can catch air then potentually tricks could be developed, spins/flips/etc like skateboarding/snowboarding. who will be the first to do a McTwist with a mono?

[Ol Dirty Diver]

I've always thought this a great shot of a human breaching. It's from an advertisement for the triathlon apparel brand Orca (same brand that Trubridge likes for wetsuits):



I'm not sure if he's using a monofin or not. As monofins are not used in triathlon, he may not be, which would make this breach all the more impressive.

The few times I've played with breaching, I had a problem with my mask being dragged off my face. Of course, the solution is simply to not use a mask. But I was wondering if you guys have discussed innovations in mask design or even headwear to maximize hydrodynamics?

I'm one of the lucky individuals that jumped on the release of 10 newly-prepared Aqueons (should arrive in the mail any day now). The inventor, Calvin Gongwer, sent some interesting literature on the Aqueon's performance. In it he provides the tip that conventional dive masks contribute an enormous amount of drag to forward propulsion (perhaps up to a third of the total drag?). I believe he created a special piece of hydrodynamic headwear for use in his impressive long-distance ocean swims.

The other thing I've thought about is overcoming the drag associated with our shoulders by filling the space between the head and shoulders with some kind of material. Of course, we already achieve this by extending the arms above the head, but there are many obvious drawbacks to this (requires constant contraction of large muscles, reduces relaxation, limits chest flexibility, difficult with restraining wetsuit, some don't have the flexibility for it, etc.). Some very accomplished divers even choose to neglect extending their arms overhead on constant weight dives due to the associated oxygen consumption (e.g.:

Herbert's 112m WR dive

Additionally, some of the ocean's fastest creatures have relatively low girth to length ratios (e.g., tuna), certainly lower than that of an average human with his arms down.

I don't have the background in physics to begin proposing ideas for applying these principles, much less to comprehend you guys' in-depth discussion of the Lunocet and all of the complex principles it involves. So I leave it to you to develop these ideas. But I do believe that putting some focus into outfitting the head/eyewear area with hydrodynamic accessories could yield drastic improvements in underwater efficiency, and is worth pursuing in our quest to realize greater underwater self-propulsion.

Sorry if this idea has already been a topic of focus in a past thread!

[Mullins]

I've played around with breaching (haven't we all!) and when you're assisted by positive buoyancy the drag you start to incur around the head/shoulders as you reach your maximum speed in those last few metres is huge.

A covering to smooth the head/shoulder area would probably make you go heaps faster but you'd end up being more of a science experiment than a swimmer. I prefer the idea of leaving the human form pretty much intact and working on better flexibility and technique. Otherwise we'll end up wearing ever more elaborate costumes that prevent us doing anything other than swimming very fast in a straight line.

Then again, we're already making use of some pretty unnatural gear so that's just my preference.

That's a pretty dramatic shot. It's look staged somehow. He could be jumping off the bottom or a platform!

But here's the target to shoot for folks (see dolpin shot from Fish PDF, page 69).

And here are two pages from same Fish PDF explaining how and why this occurs. (It's called vertical jump height) (hope this shows up)

Now THAT is a breach!

Oops... pages didn't show. I'll try again...

Looks like a guy doing a backstroke start, photoshopped onto a different background?

[Lastonogiy]

I think he is doing a start too because his arms are not in the lock yet. Perhaps the photo is not photoshopped and a guy is jumping up from the underwater thumb.
