Take a class to be a safer paddler - by Bill Vonnegut

 A few years ago I was kayaking in the north end of Lake Natoma, a small lake in Sacramento. Folsom dam releases water a couple of miles up from the put-in that flows through a canyon with some very steep walled sections. Since they release water from the bottom of Folsom Lake,it is very cold in this canyon. It was warm and sunny when I launched and headed up the canyon. A large release from the dam was causing
strong currents.

 As I made my way up I came across a group of 4 paddlers in recreational boats. Like me, they were eddy hopping up through the canyon. I said “hi” as I passed by, they looked like they were having fun but were coming into an area where the current increased. As I went around the next corner I found a nice rock with a surfable wave on it and stopped to play around for a while. Then I realized that the group of 4 hadn’t arrived yet and decided to take a peek back around the corner. What I saw was a boat with no one in it floating down the middle of the river about a 100 yards away. The boater of a second kayak was paddling around it without saying a word. I decided to paddle back and see what was going on. As I rounded the corner I saw two of the boaters sitting in an eddy, I asked if everything was all right and they replied “yes, everything is fine.” Not believing them I continued back down river where, around the next corner, I found the missing kayaker holding himself pinned up against a sheer rock wall almost chest deep and no place for him to exit the water. He was shivering in his shorts and t-shirt. I had him climb onto my back deck and paddled him down river where I was able to get him back into his boat. This could have turned out pretty bad if he was in the water for much longer.
A basic class would cover all of this and make everyone much safer on the water–likely preventing this from getting as far as it did. It would have taught them how to get their friend back into the boat on the water, how to tow the boat over to their friend instead of just watching it drift down the river, how to signal someone for help, and a little bit about hypothermia and what will happen if they just leave there friend sitting in very cold water. It may have even taught them the paddling skills to prevent the wet exit in the first place… 

 The Foundation,
 When you build a tall building, if you just set it on the ground it will still stand. But when a storm kicks up, you will want one that was built with a strong foundation. So, in construction we have professional architects and engineers that design a solid building from the ground up. Sure, you and your buddy can fumble through it and build the building on your own. But it will probably take longer and wobble a little more than if you had paid a professional who has been doing it for years and knows the best way to proceed from the ground up.  
Which brings us to kayaking. When I started paddling, I started with a basic day-long sea kayak class at California Canoe & Kayak (where I now teach) and then went out and practiced on my own. Then, I took the next level class, which reviewed the prior taught skills and built upon them. For example, in the second class I learned what edging was, the how, and why we use it (and I still to this day use these skills). I benefited from the time the school spent over the years determining the best way to teach the skills progression. My buddy could have showed me this, but it would not have provided me the foundation and progression to let me really learn it.
The type of class you want varies by the type of paddling you will be doing. For flat water kayaking, the initial focus is on basic strokes and rescues. For white water, rolling is considered an essential skill, and thus is taught relatively early on.
 Never Stop Learning,
 There are classes for all levels of paddlers. Just because you paddle well doesn’t mean you know it all. I am a certified instructor who is comfortable paddling in all sorts of conditions in the bay and on the open coast, but there is still much for me to learn.
 One day on a coastal paddle I initiated for our club, we had an incident where someone came out of his boat in a very nasty spot in the rocks. After about 20 minutes of solid efforts from the group, the paddler was rescued. Afterwards, I felt I needed to be more prepared if something like this happened again, so, together with a few other solid paddlers, we contacted Roger Schumann who developed and taught a white water rock garden rescue class for us. He set it up and we spent a whole day on the coast doing actual rescues in conditions that were challenging just to paddle in. Many of the local shops have advanced classes for all types of kayaking. Some are regularly scheduled, and some are special classes where the school brings in a renowned expert from outside our area to teach. And there are also symposiums, such as the Golden Gate Sea Kayak Symposium or Traditional Arctic Kayak Symposium where high-level instructors are brought in for a few days of intensive classes.
Also, as classes progress so does the safety instruction. Every class should have a safety component to it.
Whether it’s a river rescue class or a surf zone class, getting instruction on how to be safe is important.

Don’t Forget the Fun,
 After writing this I realized I missed an important issue: FUN. I had sent a draft to Gregg Berman, a kayaking instructor, guide, and author of articles in kayaking magazines who summed it up well: “Your enjoyment can be greater with an increased skill level, whether you want to surf or rock garden or fish or watch birds. Learning to control your boat can make you more efficient so you have more energy while paddling. And wherever you go, instead of worrying over conditions or distance from shore (though some level of awareness is certainly prudent) or whether you’ll capsize, you can play. People always remark to me how much fun it looks like I’m having on the water, because my skills give me the confidence to goof off and have fun, regardless of where I’m paddling or what I’m doing”.

So instead of sitting on the sidelines, wishing you had the skills to paddle in all except the nicest of conditions, get out and take a class and become a better paddler.

One Month until the Liquidlogic XPdition to the Grand Canyon


This years trip will be the 5th annual pilgrimage through the Grand Canyon for the Liquidlogic team.  Unfortunately I am not going to be able to go on the trip this year but what I do have is a bunch of footage that I never put together of my trip last year.  So for your viewing pleasure here is a video loosely documenting our trip self support style down the Colorado River in 12 days.

XPdition Grand Canyon 2012 from Shaneslogic on Vimeo.

Here are a bunch of photos that I took during the trip. Thanks to all the folks on the trip it was a trip of a lifetime and you all made it fantastic.  Hopefully I will be back on the XPdition next year.

Trapped Inside at Devils Slide - by Bill vonnegut

 “Myself and a few friends got together for a paddle down the coast last December. The plan was to start a Linda Mar beach in Pacifica and head down the coast to Grey Whale cove while exploring the rocky features on the way. The forecast swell for that day was about 4-5 ft with a larger 9ft swell coming in late that night. We discussed before launching that we may get some bigger than average waves rolling in ahead of the upcoming surge. However we were not expecting the extreme change in conditions that occurred while we were working our way down the coast. Going back to the Half Moon Bay buoy history for that day this is what we found: According to the HMB buoy:
                       Wv-Ht     DPd    APd
        1:50pm    4.6           12      8.1
        2:50pm    5.2           21      9.1
 Note the 21sec period waves mixed in. These readings came a short while after our incident occurred, but we were there for the preview. Since the longer the period swell travels faster than the short they will arrive first and since the height of the swell was almost the same as the short period swell these would be hard to see coming also break in deeper water so that would explain how that first set seem to have come out of nowhere on the outside of our position. We paddled down the coast that day exploring many coves and features along the way. It was a normal day with very consistent sets of waves some bigger than the others but nothing more than an average day. As we neared Grey Whale cove our destination for the day we had paddled into the bay just north of it. This is an interesting area where you find constant waves reflecting off the wall of the cove and colliding with the on coming swell creating a zipper effect.
We have been in this area before under what seemed to be at the time larger conditions and found it a very exciting area. Everyone who went close in to this area had a solid roll. We had been in that cove for a while that day and had seen where the biggest sets would break and were staying outside of that area. I was caught totally off guard to what happened next. A wave up from what seemed to be out of nowhere appeared just behind me and caught me totally off guard. It knocked me over and picked Mark up and dragged him quite a ways into shore. Since that wave was much further out than all the waves that day and I had seen nothing break in that spot, I made the mistake of watching Mark rather than looking outside like I should have. Then I turned around and saw a monster wall up on the outside. If you notice the shot in the video where Cass is backing his 17ft boat over this wave and narrowly escaping, the face of the wave is at least a few feet longer than his boat. There was not enough time to turn into the wave so I ended up getting broadsided and sent screaming toward the rocky shore. All I could do was lay the boat on its side with the boat between myself and shore and side surf awaiting the collision with the rocks that I was sure to come. To my great relief the wave pushed me into a small cove and let go of me. At that point I had no idea if the next wave would come crashing over me or not. So I decided to jump out of the boat and scramble up the rocks and asses the situation. At that point I saw Tony paddling up, note that Tony’s hatch cover got blown off and he made it to the beach paddling a boat full of water. Mark got washed into the same cove after he had lost his boat to a large wave that had blown his spray skirt just outside the rocks.” Myself and Mark ended up getting trapped inside what was luckily for us the only spot in the large cove that did not have sheer cliffs. So we decided to climb our boats up about 800 ft to HWY 1 rather than risk getting stuck in another spot where we could not get out.

 Sergey was also hit by the same wave but was out of my camera range. He ended up loosing his spray skirt to that wave and we have been impressed how he has done a great job building his skill level in the short time he has been paddling.
Bill Vonnegut

 This is Sergey Yechikov's account of what happened and I would like to share it: “As for the incident I believe that boat full of water worked as a sea anchor that prevented me to be washed ashore at the same spot as you guys. I did rolled back after a first set of huge waves but realized that I am flooded and can not make over breaking stuff due to instability. I tried to swim away from impact zone and empty the boat enough to scramble in. I almost did that but was knocked over by the second set. Then I kept swimming to the right side of the cove seemed to be more safe and eventually trying to empty the boat. I had 2 possible options in the mind in the case of failure – abandon the boat and swim toward Cass and Peter or let the wave wash me and the boat onto the same spot as you. But at that moment from what I saw I was not sure that we can hike out of the spot. Luckily I did not have to make such a decision since I put my foot onto some solid surface. Probably that was rather a top of the rock than a sea floor because later I was not able to reach it. It was enough to partially empty the boat and do re-entry and roll. Then I punched through another set of breaking waves and paddle out to safety in submarine mode. Peter tried to reach me but I sent him away as we were still in breaking zone. Then we left the zone we did T-rescue to dump all water out.” Best, Sergey. “This is a good reason why you should use a high quality white water skirt and have float bags in the hatches when paddling on the coast. I will leave it here as I have a video below that explains the whole incident very well”

Parsing Jerez: SBK/CRT/MotoGP

I used to think that MotoGP and World SBK went out of their way to avoid giving punters like me a chance to directly compare lap times. But the recent Jerez test, in which the world's two premier classes briefly overlapped, allowed for a nearly apples-to-apples comparison.

Let's call it apples to quinces.

Sure, the fastest SBK lap -- Laverty (Aprilia) 1:40.1 -- was a banzai effort on Pirelli qualifying tires, while Hayden's fastest lap of the test, coming a day later, was a 1:40.090 done in serious testing-for-data mode on Bridgestones. And Superbike Planet may have been correct to point out that "Jerez has never been a sweet spot for the Ducati." (Although when MotoGP raced at Jerez last April, in similar conditions, Hayden recorded essentially the same best lap, and started from third -- wouldn't that have made it his, and Ducati's, best dry qualifying session of the year?)

More to the point, while the fastest SBK bikes and riders were present in Jerez, the fastest MotoGP bikes and riders were not. I'm guessing that Lorenzo and Pedrosa, had they been present, would have put in laps in the 1:39s, just as they did when they qualified 1 & 2 there in April.

What was more interesting to me than any single best-lap stats, however, was that Melandri and Sykes were both under 1:41 on Superbikes as well. I.E., the best laps recorded by three different Superbikes at this test would have qualified ahead of Ben Spies, who was just over 1:41 on the factory Yamaha MotoGP bike last April.

Unanswered question: how much faster are the fastest MotoGP riders than the fastest SBK riders?

My point in all this is, at least in a qualifying-at-Jerez simulation, the fastest Superbikes are at least as fast as MotoGP prototypes (if the prototypes are ridden by humans, not aliens). 

Plus ca change, plus c'est la meme chose, eh?

Ten years ago, we were kind of shocked when, during qualifying for the British Superbike Championship round at Donington Park, Steve Hislop set the outright motorcycle lap record on his Ducati Superbike, eclipsing Valentino Rossi's record set on the fire-breathing Honda 500GP two-stroke. Hizzy was a special case, but it's clear that the technological convergence of Superbikes and MotoGP bikes have resulted in a lap-time convergence, too.


Where were/are the CRT-class MotoGP bikes in all this? Last April, the fastest CRT rider was Espargo, who was four seconds off the pole. Over the course of the year, the CRT bikes in general and Espargo in particular closed the gap. At the season finale last month, Espargo was two seconds off the pole. Which is good, for what it is, although I guess the CRT experiment won't be very long-lived if Honda comes through with a promised customer MotoGP bike.


I don't want to say, "I told you so" (OK, I love saying that) but it was obvious that the CRT bikes weren't going to be faster than the Superbikes from which their engines were sourced. It's still interesting that they aren't faster. 

I mean, you're basically taking a Superbike motor and handing it to a bunch of really smart guys and saying, "Throw out the rest of the rule book; give it carbon brakes, go nuts." But at the end of the day, what they make isn't faster than a production-based bike that's fairly tightly constrained by SBK rules.

Unanswered question: How much faster are the fastest SBK riders than the fastest CRT riders, if at all?

Why haven't CRT class bikes improved on production-based SBK lap times?

  • As important as the bike is to the rider, it's not as important as the rider is to the bike.
  • Current production bikes are fucking incredible, and yes, they really are almost as fast as MotoGP bikes. This is crazy, really. Anyone with a reasonable job can afford a street bike that is almost as fast as the fastest prototype. It's as if a showroom Dodge Charger was only a few seconds a lap slower than Sebastian Vettel's F-1 car.
  • Motorcycle chassis are complex, dynamic systems. If you took all the restrictions off the chassis, you could use a Dodge Charger motor to power a car that could lap within 10% of an F-1 car. It's not so easy with bikes.
  • More than anything else, electronics -- it's your choice whether you call them 'traction control' or 'rider aids' -- have become the rate-limiting factor in motorcycle racing.


Now that Dorna controls both MotoGP and World SBK racing, it will be interesting to see how they go about packaging the two racing 'brands'. One thing is sure: the prototype class loses its raison d'être if it is not faster than the production-based class. With cost-control and safety concerns arguing against any changes that will make MotoGP bikes faster, the only solution in sight is making Superbikes slower.

Until they do that, they'd better avoid putting Superbikes and MotoGP bikes on track together.

Ford Fiesta 1.0 ecoboost - economical & refined!

Fiesta ST 1.6 ecoboost


The advanced 1 litre 3 cylinder engine first seen in Ford's Focus has now found a home in the latest incarnation of Fiesta and will come in three different specifications - two ecoboost (or turbocharged to you sir!)98 or 123 bhp and one normally aspirated version of 79 bhp. Economy will be around the 65 mpg mark for the more powerful version and should be higher for the less powerful models.

The advanced design of the 1.0 ecoboost engine means extremely light weight and near Motorcycle levels of horsepower and a perfectly reasonable 148 lb ft of torque, remarkable figures from such a relatively small lightweight engine.

Lower weight means that the already class leading Fiesta, introduced in 2008, improves it's handling and poise still further -  this car is quiet, refined, good-looking, fun to drive and economical !!

It can't make a cup of tea though - yet! Although the Fiesta does have some trick features up it's sleeve, like the MyKey system, which allows parents to limit the car's top speed to 80 MPH and also the radio volume. Another feature of note is Sync - one of the most advanced systems around for integrating mobile phones, audio and voice control, although this has proved unpopular with Americans, who have had the system for a few years.

All 3 models come in under the 99g/km emission threshold meaning cheap road tax.

If you like your Fiesta to come with a bit more oomph, the ST version 1.6 litre ecoboost (pictured above) is also due out very soon, and should be a little firecracker with 180ps available through the front wheels.
