I've got a knotmeter from speedtech http://www.speedtech.com/asp/prodtype.asp?prodtype=35 which records distance travelled, along with speed. They have 2 models of interest to a paddler. An impeller verion that has a small "propeller" on a fin that attaches to your boat. The other version is a trailing wire that you just drop over the side. Neither model requires putting a hole through the hull. I used it a fair amount on a couple outrigger canoes (single and double) that I paddled this year. It's great for letting you know right away what effect boat and stroke adjustments have to your speed. Since we were practicing while paddling into a stiff current the knotmeter gave our real speed in the water versus a gps which would have only given our speed relative to the planet. The impeller version is basically 3 pieces. The reciever, which has nice big legible numbers, that attaches to an angled plate which is velcro'ed to the boat. The impeller is in 2 pieces, a base plate (fairly hydrodynamic, that is about 1/2" by 2" (1.25 X 5cm) and maybe 1/4" thick) which attaches with 3M adhesive, and a removable impeller/fin that slides into the base plate. If you change boats a lot the trailing wire is probably preferable. Additional base plates are available, but they are "permanantly" attached to the boat so you can't get speed results in a borrowed boat. I would be interested in finding a source for the 3M adhesive, since I bought the impeller version but paddle a lot of different boats. The results do go haywire when you go under high tension power lines. I'm fairly certain we never got the outrigger doing 35 knots ;-) Kirk -- http://fastmail.fm - Consolidate POP email and Hotmail in one place *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
