Fresh water CWT

Thread Status: Hello , There was no answer in this thread for more than 90 days.
It can take a long time to get an up-to-date response or contact with relevant users.
I think Herbert did a WR 100 FIM in fresh water, but I don't know of anyone doing a CWT 100 in freshwater.

Have you found a good location?
 
Nice to hear that Dave, I hope you can be the outsider doing the next WR CWT at Vertical blue. Are you on schedule? Did you find any useful new better approach?

Guilliaume told me that for his WR 113m he trained strength and sprinting, speed was to be important.

Personally I've been only to 65, but I did notice that for swimming up a small undulation and higher frequency is more efficient.

Did you notice any much difference to salt water?
 
I seem to be going pretty well, this year I'm trying to spread out my CWT training so I don't need to do heaps of deep dives right before the comp and tire myself out. I'll be happy if I can push it out to about 110m in the lake before heading over.

I've been doing more strength/speed work this year too. Using long DNF swims to train endurance. Diving lighter, drifting down at 1.2m/s and coming back at 1.5m/s (the opposite of what I was doing in 2008). Taking a leaf out of Herb's book and going slower in the first 20m, with only a half-hearted attempt at streamlining. That kind of thing :)

difference to salt water - I'm more used to training in the lake than I am in salt water; the main difference is obviously the buoyancy. I'm wearing a 3mm suit with a 1.5mm vest and heaps of packing, but only need to wear 1kg. Viscosity seems to be less as well (the fin seems to get less purchase against the water), but I'm still not sure if I'm just imagining that.

!!!!!!! DAVE is back! good to hear the training is going well. i agree fresh water is very different to salt, less weight makes a big difference for me coming off the bottom.

DD

Good luck at vertical Blue mate!
 
Sounds like some radical changes Dave!
So how's you equalisation coming along? And did you manage to deal better with and/or lessen the narcosis?
I agree with Herberts slow entry approach, it's better to let your body ease in the transformation, than to force it.

From my own experience, I find diving light, little suit and weights, very pleasurable, especially at depth where it's easier to get and maintain more speed up. And in you case diving light yields out of a 100, a 90m of lighter swimming, with only a 20m tougher entry. Having less mass is also good for the monofin, as you'll stay within it's rubbers elastic range not overpowering it. At depth it's easy to overpower the fin, as you'll not only have to overcome the water-resistance but also pushing up your body mass and it's negative buoyancy.

How are CNF and FIM coming along? (with your hight you have an advantage over the small devilish William I think ;)

Oh and for the spectators of the vertical blue event, what's your nickname?

Ok, I'm off to the pool, seeking some relaxation practising my subconscious swimming ;)

You may be well the first, Dave. In the records I see only 72m at Herb in a lake. Although it does not mean he did not make more in training, I did not hear about any 100m in fresh water yet. Christian Maldamé does some deep training in a lake too, but I do not think he goes that deep.

Anyway, congrats, to the achievement. Pretty amazing!
 
Herbert did 95 m as WR in fresh watter in 2003. Maybe he did more in training?

Dave 1 kg to your body, lung volume and 3mm suit + 1,5 mm vest is not much. How did you measured the depth? Depth computer is calibrated to salt watter so if you measured by this way it could be even deeper?

In Czech Rep we are forced to dive in fresh watter too. In a better case there is absolute dark in 40+ and a constant watter temp 4 degrees :-) (Same as in Herberts case). It would be interesting to dive 100 in a such case. Unfortunately we are limitted to something about 70 meters :-(.
 
You're lucky Michal, we don't have more than 60, and for that one you need a boat. Generally it's here dark after 20m, so enough mental training here!
 
a soft mud bottom yes, pretty scary when you land abruptly and have not only you head in the mud, but also your outstretched arm.
Now, to avoid sharing the is unique pleasure with the wimpy beginners, we hang the plate a little over a meter above the bottom. Admittedly this happened to me only at -23m, but the feeling of being stuck on the sucking bottom in total darkness wearing a monofin is pretty scary non the less. Therefore my second freediving fear is bumping into the bottom. The first one is bumping into the wall in the pool.

Let me ask one more question regarding the dive speed. If you dive 1.2m/s wown and coming back at 1.5m/s, it takes you 1:24 down and 1:06 back? Does it all take 2:30? Is it your common speed? To me it seems rather fast :confused:.
 
I think it's a nice speed too, but do not forget he now makes a slower entry, excuse me an Herbert Nitch entry ;)

It sounds like his dive is better balanced and he needs a lot less energy over all.
Guilliaume also choose to go fast, doing his latest WR in about 2'30" - 113m! - if I'm not mistaken.
 
Michal, it was a measured rope but because of the fresh water difference my watch only read 98.7m. 1.2m/s is my peak descent speed, which I only hit from about 30-40m onwards. Before then I'm going pretty slowly. The 1.5m/s ascent rate I maintain for almost the entire ascent though, so the dive was 2:50.

Kars, equalisation and narcosis seem less of a problem now. As soon as I got back into CWT after the long layoff I seemed to have a lot more air than I did in 2008. I've only had three or four weekends in deep water so I haven't been able to do FIM or CNF yet.

Conditions in our lake are a bit more pleasant than in yours Michal - at the moment it's 10m vis, 18c surface temp and about 8c on the bottom, thermocline at 32m. The kind of place you can hold a worthwhile CWT competition, except the wind forced us to abandon nationals earlier this year.

Wow, that's not bad, I would think more like 4C. vis. is decent too and thermocline is deep. But still - with 3mm suit, aren't You getting cold?

For me that is a must 5mm

And what is the darkness depth?
 
I'm ok in a 3mm as long as I don't stay in the water very long, the vest helps a lot. Some of the others have been using a 5mm top and 3mm pants. It was very gloomy at 100m but I could still see the plate, just.
 
Indeed 3mm and vest is a nice setup, even for skinny people like me. For me it's key that my chest, head and belly stay warm enough to allow for flexing with the pressure. Limbs can get cold, but that's not that bad.
Granted not good for hours and many long dives, but for a quality dives it will do.

Well Dave I think you're blessed even to see the plate at a 100! wow! Maybe some day I'll have the same pleasure :) Hopefully without needing a sled or tanks.
