Science of fastest stroke? --Stand, kneel, canoe, kayak?
I'm thinking there's probably been both science done and comparison done
between all the various possible ways to paddle. Anyone have any details on it? Here are the options I see: *standing up, single blade *standing up, poling *high-kneeling *sitting, canoe *sitting, kayak (dbl blade) I've recently been fooling around with stand-up paddling. Man, it's fun! And it seems very fast and all-body dynamic. I vaguely recall that highkneeling is tested as faster than paddling even over a long distance, so I'm wondering if maybe standing is faster yet. ?? It seems like one can also pole nicely with a stand-up paddle when it is shallow then paddle well when it's deep. But poles supposedly paddle well when deep as well and really get traction in the shallows. Anyone know how all this plays out? Thanks. I was out standing in my J200 the other day. That's still a somewhat viable fla****er race hull. Not too bad. Tippier than my Advantage, for sure, but quite a bit faster shape, too. I heard from a local guy who has a 6 foot paddle for me to test in standing. --Big George Stockman (of yore). I believe he has a national OC title or two under his belt.

Heh, heh. I'm not, frankly, very interested in all this (I have never
raced because I have never yet put on a river with the express intention of getting back off it as soon as I can; I take my time and make the most I can of the river) but I can tell you *this* much "science": Kayaks have two distinct speed advantages over canoes (not to mention other advantages not directly related to speed). These are (1) nearly double the natural stroke rate, because each "recovery" stroke is simultaneously a power stroke on the other side, and (2) alternating power strokes from side to side means a kayaker (going straight, no current, etc.) never has to make a correction stroke or waste time *hut-hutting*. Correction strokes reduce yer speed in two ways, (a) yer forward stroke rate is reduced due to the time spent correcting rather than powering, and (b) there is a small braking component to every correction stroke. -Richard, His Kanubic Travesty -- ================================================== ==================== Richard Hopley, Winston-Salem, NC, USA rhopley[at]earthlink[dot]net 1-301-775-0471 Nothing really matters except Boats, Sex, and Rock'n'Roll. rhople[at]wfubmc[dot]edu 1-336-713-5077 OK, OK; computer programming for scientific research also matters. ================================================== ==================== Jeff Potter typed: I'm thinking there's probably been both science done and comparison done between all the various possible ways to paddle.

I can't imagine labeling those WW 'slippers' as boats. Or not going anywhere, as per today's WW mode of simulating liftserved skiing on water. All that waiting your turn for waves...yuck! Kayaks have two distinct speed advantages over canoes But are these realworld advantages? I don't recall that kayaks beat canoes in distance events. Maybe sometimes. Doesn't one typically get more lactic buildup when kayaking for speed so that the events are shorter? I vaguely recall that highkneel beats all even in 2 hour events. Hmmm, maybe Landick used a kayak paddle in his huge hull at the Texas Water Safari---or maybe he alternated paddle-types. Oh well maybe someone has some real science. -- Jeff Potter **** *Out Your Backdoor * http://www.outyourbackdoor.com for modern folkways and culture revival... ...offering "small world" views on bikes, bows, books, movies... ...new books featuring: XC ski culture, a Gulf Coast thriller folding bicycles ... with radical novels coming up! ...original downloadable music ... and articles galore! plus national "Off the Beaten Path" travel forums!

Why I prefer 'hut-hut-hut'...
10. If it's over mild Class 2, I don't want to be there anyway... 9. I don't get warm for at least an hour 8. My paddle weighs a lot less than yours (8-9oz) 7. I like paddling balanced on a razor blade. 6. Riding/drafting is a lot tougher with a double paddle 5. Hut gives your partner something to do 4. I can see farther down the river than you can 3. My back hurts too much sitting down in a yak for that long 2. My boat weighs less than yours does (and the real reason I like sit & switch) 1. My knees would never put up with a high-kneeler anyway. Aside from poking fun at each other, I paddle sea kayak, surf ski (a little) touring and racing canoes. I can't imagine taking a kayak to most of the places I go in the BWCA, nor would I take a canoe to Superior. While I *can* J-stroke, I prefer to 'hut' even when touring. Experienced paddlers/racers lose perhaps 1/4 stroke per hut, so assuming a 72 stroke/min and hutting every 6 strokes, that's only 3 strokes/ minute lost. Not quite what Barton can do in a K-1 over a thousand meters, but I'm still going at that clip after 3-4 hours. As they say, 'different strokes'. I fully appreciate His Kanubic Heresy's goal of leaving no hole unsurfed, but I'd rather a different way. (and no waterwings requiredG) Marsh Jones New Brighton, MN Oci-One Kanubi wrote: Heh, heh.

Friend of mine who's into adventure racing tells me that in one race they lost to competitors who used twin-blade kayak paddles in canoes, I assume because of the advantages that Kanubi elucidated and enumerated.

I'll be curious to see how you manage to 'pop' a boat going thru the
shallows while poling. Have you tried standing up in your J200 while getting beam waved by the kids in their butt-dragging wakeboard boat? I go out and do 'fartlek' on one of the local lakes here just to play in the ski boat waves, and have played submarine just from the curl coming up over the wing on my Jboat. The local hotshots have a wake board specialty boat with a tuna tower and a ballast tank to make the stern really dig in. It does generate a significant wave - 2-3 feet before it hits the shallow. Poling and standup paddling have their place in the swamps and even going upstream in rapids, but I'd caution trying to make them cure-alls - rather another tool in the arsenal.

Poling is simply the best in the shallows from what I can tell, and I'm a longtime hutter. I seem to stand-paddle fine in the shallows, too---but not enough data yet. (Long paddle also seems to make a good pole. I'm interested in testing 6-7' paddles.) --JP |

(Long paddle also seems to make a good pole. I'm interested in testing 6-7' paddles.) Hey Jeff: glad to see youre still a poling afficinado. My primary method of canoe movement is poling. I take a 6" beavertail paddle and a 16" pole whenever I go on trips, and I find that I spend about 80% of my time poling. This is in shallows, fast water, slow water, rocky rapids, moving upstream, and moving downstream. The only water I don't pole in as a matter of habit is deep, flat water, because the pole just doesn't work as well as a paddle, and the correction stroke (really a long drag of the pole behind the boat) slows it to almost a stop between strokes...not very efficient. However, in any river where you can reach the bottom, there's no replacement for that satisfying feeling that every single push of the pole results in forward motion. And its a lot more comfortable walking around my boat than sitting there on my butt and knees. However, again, the correction strokes (a little pry against the hull behind you) takes away some of the forward motion. Anecdotal evidence: When I was on the Snake River in the NWT, leading 6 other tandem boats on a river with some good current, I was poling in the lead so I could read the braided channels between the islands. After a few hours, the clients begged me to paddle instead of pole because they kept piling up on my stern since I was going so much slower than them. I assume its because I was snubbing (slowing down) as much as I was drifting, to buy time, but even in well-known channelized rivers, I find that poling goes about 2/3 as fast as paddling, except in hurried, thrashing races which only last for a few minutes until you are out of control. --riverman (A man at olympic event sees another man carrying an aluminum pole. He asks "Are you a pole vaulter?" The other man says "No, I'm a German, but how did you know my name?") |

You're a boater dog, dude! : )
Yeah, walkin around the boat is where it's at. But our territory must be different and styles too, but stand-up and poling adapts to em all just fine, eh? I tend toward the race style and I don't use correction strokes and am on fla****er. So from my experience so far both standup and poling seem FASTER than sit-down kayak or single. But my data is mostly subjective so far. I did one 1-mile fla****er up and down test and my times were about the same. Oh, it's also far superior for obstacle-clearing. Step out, heave, step back in. Or for real shallow water: step out, trot along, step back in. So nice! I can pole or stand up indefinitely it seems, at race pace. As easy as sitting anyway. Good rhythm, no worries. Good hull speed carrying along (when I stand in middle, or end up with weighted foot in middle after thrust, anyway---it's very dynamic). -- Jeff Potter **** *Out Your Backdoor * http://www.outyourbackdoor.com for modern folkways and culture revival... ...offering "small world" views on bikes, bows, books, movies... ...new books featuring: XC ski culture, a Gulf Coast thriller folding bicycles ... with radical novels coming up! ...original downloadable music ... and articles galore! plus national "Off the Beaten Path" travel forums!

Thanks for helping with this probably obvious stuff.
I recall that 30 mile marathons in Europe are still won with highkneelers, tho. So the design isn't always stressfully tippy. Also a friend of mine went overseas and used a highkneel hull in the sit-down marathon style at the Worlds and other events and 'only' got fourth. I recall he was real impressed with the kneelers, but maybe he wasn't at his own fitness peak then. Again, for a, say, 2 hour race in a given hull, which paddle style would win based on science? Kayak, highkneel or sit'n'hut. ?? Cutter wrote: I'm not sure what you are really seeking. A kayak will be faster given similar hull design. I base this in finish times in 500M and 1000M Olympic events vs. a canoe. A kayak's cadence is faster, though each stroke is weaker. More x weaker = faster. Yes a high kneel canoe is faster than a low kneel, or sit down marathon style. It is very tiring when distances exceed 10,000 meters. The fastest paddle boat out there? K-4. The boat most likely to finish a 150 mile race in front... a sit down canoe. Any energy used to keep a tippy boat upright will depleat energy available to propell it. This is why a good 500 M boat may not be a good 10,000 M boat. -- Jeff Potter **** *Out Your Backdoor * http://www.outyourbackdoor.com for modern folkways and culture revival... ...offering "small world" views on bikes, bows, books, movies... ...new books featuring: XC ski culture, a Gulf Coast thriller folding bicycles ... with radical novels coming up! ...original downloadable music ... and articles galore! plus national "Off the Beaten Path" travel forums!
