Kona

I have to put in some culinary content here, so below is a picture of Lava Java, which is in the main plaza in the center of Kailua, Coconut Grove. It has excellent food, from coffee and pastries to full-on dinner. Our group eats there all the time -- Performance Freediving should try to get a deal or commission from them, but the company is way too busy with its core-mission to have time for things like that.

Saturday
I finally got my act together to do a max breathhold in the pool. If you don't get a consistent procedure down, then it's hard to do a max breath hold, you experience a lot of discomfort, and if you're lik me, you wind up quitting early. That's why, e.g., I only did 5 min yesterday. Today felt pretty good, so I was going for 6:30. I planned to "wake up" at around 6 mins (conserve energy for the first part, then wake up at the end to monitor whether you are going unconscious/hypoxic). However, I started to go hypoxic at 5:40, so came up at 5:45 with what we call a loss of motor control. Instructors said it was probably beccause I did a lot of deep diving yesterday. Hypoxia from one day does not generally carry over to the next day, at least not in a major way, but I guess it does in a minor way, and this incident is an example of that, as 5:45 breath hold shows a diminshment in oxygen capacity, but a minor one. However, since oxygen deficit does affect the rest of the day, because of my incident, I would not be allowed to dive the rest of this day.

The rest of my time in Kona is going to be spent on safety drills and learning instruction, so I might not get a crack at 50m or even 45m. That's OK because it's actually more important for me to perfect my technique to 40-42m than to just force it down to 50m. I may get to squeeze in a few of those between drills. I also will be able to practice some 40-42m if I teach for them in coming months.

Friday

Did an easy 5 min breathold in the pool (Ben did 6:30 yesterday). Went to the ocean and did two 41m pulldown dives fairly smooth, but not perfect with the equalization. I have never had been able to get beyond 40m with at least some pause for equalization, but I'm getting better. Also I did not feel tired at all after doing 41m dives, so my tolerance for depth is getting better.

More Kona

Thursday
Went to the ocean in the afternoon and did 2 41m pulldown dives.

Wednesday
Today the advanced class started. Went to the ocean in the afternoon, had some problems with my equalization procedure, only got to 37m.

Tuesday

On Tuesday morning I accompanied the class to Place of Refuge.  I helped quite a bit more this time, helping set up, working with the two people with ear problems, and doing some safetys and practice rescues.  I also squeezed in a 37m dive, which came quite easily.  So that counts as my warmup for the advanced class starting tomorrow.  Most of the students in the class were able to do 30-40m.  No dolphins today.  Now I have the afternoon off.

Oh, here is my application for the Great Barrier Reef job that has been making the rounds on the Internet.

Kona Out of Time

So my friend Ben just posted video of my last trip to Kona, November 2008, so please don't be confused just because I am here now.

Here are two videos, which I won't bother embedding here, I'll just provide the links.  The first is my dive to 44meters.  On the way down I had to pause to deal with pressure equalization issues (I seem to have this problem more than most freedivers).  On the way up I took a few initial arm pulls as a little safety margin, as it was my deepest dive to date.  In fact, I would be inclined not to post this video, except the bonus, DOLPHINS!

Look at the end of the dive and you can see a dolphin behind me.  Dolphins in Kona are rather ho hum, though.  After the dive is some more dolphin action.

The second video is a more textbook dive to the same depth.  Julie is a member of the Canadian national team, and her dive is a lot smoother.  She is also using a top-of-the-line monofin and freediving suit (low-friction smooth skin).  It was also her personal best.

Monday

Went to Place of Refuge in the afternoon with PFI.  I was somewhat useful this time, as two people had trouble equalizing pressure even at a few meters, so I worked with them directly.  Mandy and Kirk said I could also get in a few dives since I would have a small three-person safety rotation with them.  I had plenty of time to do this, but events conspired against me again, as another diver forgot his depth gauge, so I had to lend him mine, and the lens in my mask came loose, causing it to leak and making it hard to do deep dives.  Still a good day.  I think I left my shoes at Place of Refuge yesterday and of course they were gone today, but even I know that's not a big deal (probably got them at Big 5 for $25).

Sunday

In the morning, Bill gave me a ride down to Place of Refuge to join their regular Sunday diving group.  These people are quite serious, and train almost every week, so many of them are over 70m.  I made a somewhat poor decision today.  I started following them out to the deep 75m buoy but lost track of them.  I thought I had an idea where the buoy was, problem visiting it a few years ago, but I was wrong.  So I swam around for a couple of hours looking for them.  I went out way too far, and so it took my a while to get back.  The group was mildly concerned until I showed up.  It wasn't a very much of a poor decision considering this is a sport with a high mortality rate.

As soon as I got lost, I should have swam back to shore too see if I could spot them.  If I had done this I might have been only 30 mins late.  Also, if I wasn't going to be able to see them from shore, I certainly wouldn't have been able to see them bobbing in the ocean.

I had been hoping to start my trip off this day with a 35meter dive as a start.  Oh well, again, another day in paradise.  The two positives are that I got a hell of a workout swimming around (a few miles at least) and I ran into a five-foot reeftip shark.  I was swimming around and I kicked something solid.  I heard something thrash and I saw the shark swimming off.  I don't think they attack people, but they could definitely deliver a nasty bite.

After I came ashore and checked in with the group, I went out with the PFD group doing their first ocean session.  Again their wasn't much for me to do, but it's always fun out there.  I had a spinach salad for dinner, then the butter avocado.  I love avocado but that a little too much.  It weighed almost a pound, albeit with a large pit.

Sat

Performance Freediving started their Intermediate clinic today.  I joined them in the afternoon and did a 4 minute breathhold in the pool with them, along with some rescues.  Their are twelve people in the class for three instructors, which are perfect numbers, so I'm kind of a third wheel.  If there had been an odd number and/or a few too many people in the class, I could have paired up with someone and had more to do.  But I can't complain, it's another day in paradise.

Kona, Fri February 13

So why did I take the time to muse and write about the above decision rather than just looking to the right (in terms of decision theory) and just get right out and enjoy Kona?  I think that bears some discussion. For one, I have been to Kailua Kona almost a dozen times so it is more of a second home to me than truly exotic. Also, admittedly, I am more of a thinker and a described than a doer. In the past, the problem was that my thinking would be so abstracted from experience that it was irrelevant. I think I have managed to fix that, now I make sure to experience things enough to make my commentary meaningful, but that I am still by nature more a thinker than a doer.

For instance, I am probably not going to be the guy that freedives to 100m (the current world record is 113m). I am the guy that may dive 60m and does a physiology study on the 100m guy, or writes an article about the sport for Outside Magazine.

In any case, I did get out of the condo and took a quick walk to the farmer's market, where I scored a butter avocado, three sherwil avocados, and a pound of rambutans.  It's the dead of winter in Kona, so the temperature is like 75F.  Traffic in town is crazy due to the long weekend! I saw a Model T Ford in the streets.  The surf is pretty pounding in Kailua.  However, we dive at Place of Refuge, which is generally safe from swell.

The condo  is right next to Jack's Diving Locker, and while the building is a little worn, the condo itself is quite nice, 1 BD 2 bath, quite a deal for $99/night plus tax I think. Since the condos are individually owned, they may vary in quality. This one is Kona Alii #209.

Now I am off to do my pranayama yoga (life force/breath practice) which I learned from Elle in LA. I'm thinking maybe eventually I can learn to control my heart beat.


*****

My loose goals for this trip, in order of importance are:

(1) become a certified instructor with Performance Freediving

(2) take a 15 second rest in the sand at the shallow buoy (45m/147 feet)

(3) do a 50m dive (167 feet) at the deep buoy (about 80m)

(4) complete a 100m underwater swim (no fins)

I just had dinner with Mandy, Kirk and Craig.  The local rental agency didn't have any cars, but Kirk was able to get a 12 seat minibus at the last minute from Thrifty, but not cheap.

Freedive to 32 m/ 105 ft/ 79 sec with cheap snorkeling fins, Catalina Island

My very first youtube video, couldn't resist embedding it here. I didn't get any fish or seaweed on this dive.

With Performance Freediving intermediate class, Sept 2008. I would be invisible at the bottom save for the day-glo fins. I did 44/144/100 with a monofin in Kona, November, but don't have video of that.
