    ICF Paracanoe Racing

    First, a video that explains the three levels of disability that characterize the single blade paracanoe flatwater sprint race classes: VL1, VL2, VL3. V stands for va'a, which is an outrigger canoe with no rudder or skeg. The 1, 2 and 3 relate to different levels of disability. Next, I will...

    Puffer Tents

    "People certainly might be inspired to get out and camp more if pitching a tent becomes as simple as connecting a battery-powered electric pump and letting it fill the tent into shape while they take care of other camp setup duties. And if that tent sets up in about two minutes flat, all the...

    the physics behind a canoe's pivot point

    Approximately. When the boat is at rest relative to the local water, the pivot point will be under the combined boat+gear+paddler center of gravity (COG). You will probably be shifting the COG a bit, and hence the resting pivot point, as you shift to place your draw stroke in different places...

    the physics behind a canoe's pivot point

    You can empirically test this with the help of another person. The more technical name for the pivot point is the center of lateral resistance (CLR). If you are in your stern seat with your usual gear load, the boat will move perfectly lateral, with no left or right bow yaw, if someone pushes...

    the physics behind a canoe's pivot point

    When a boat is at rest with relation to the water around it, the center of lateral resistance (CLR)—more colloquially known as the pivot point—will be located at the center of gravity of the boat+gear+paddler. In a central seated canoe with no gear, that will put the pivot point at the COG...

    How to recruit new canoe paddlers?

    I like learning new words. I can now relate canoeing to Aesop's Fable about the testudine and lagomorph.

    tent cleaning and treatment

    Hmm . . . so I just looked at the North Face Warranty page. The warranty "does not cover damage caused by accident, improper care, negligence, normal wear and tear, or the natural breakdown of colors and materials over extended time and use. Proof of purchase may be required." If I were North...

    tent cleaning and treatment

    On 15 and 20 year old rain flies from two different tents, a Nemo and a North Face, I've had the stickiness problem, which then progresses to flakiness. In both cases it was the waterproof polyurethane (PU) coating delaminating and breaking down. Nothing to do with sap or forest detritus. PU...

    Poll: Rudders

    I've only had a rudder on my outrigger canoe. It definitely eliminates the need for correction, either by single-sided correction or by switch paddling. I only switch paddled to keep both arms in paddling shape and to reduce muscle fatigue in one arm. Hence, a ruddered canoe is more efficient...

    Moving and turning a canoe left and right with balanced and unbalanced side slips

    Search in the AI world for a boat's "peripatetic pivot point". You can then report the answer to your question on this site, but start a new thread. Although the phenomenon relates to velocity slow downs during side slipping, a full technical discussion with the new source material available...

    Good Find? LL Bean Edition-Old Town Camper 16ft

    The Camper was made in a 15' and 16' version. Both were stable and popular family and cottage canoes. Which is this? I assume a 16' would be worth a bit more than a 15'. The HIN will tell you in what year it was made. It looks in pretty good shape to me, so I'm not sure there's much to...

    Old Canoe

    Old and rare models of canoes, like old and rare models of any product, are often rare for one good reason: They were never popular to begin with; there never was much demand for them. Hence, demand for such an unpopular old model will even be less now than when is was new. Such old models won't...

    Moving and turning a canoe left and right with balanced and unbalanced side slips

    Chris, I'm glad the article caught your technical attention. What you're asking is essentially how, technically, to execute a static side slip. That's not the focus of the article, but "how to do it" is a very important technical question for all paddling control moves. If folks want to discuss...

    Moving and turning a canoe left and right with balanced and unbalanced side slips

    That's not the title of Marc Ornstein's most recent single blade technique article, but it could be. Marc characterizes the hydromechanics of draws, pries and side slips this way: " . . . bow and stern, draws and pries are essentially 'unbalanced' side slips, as you might say. Whereas a...
