C'mon gearheads! Get a hand-held anemometer. They run from US$25 - US$165. Try Edmund Scientific Catalog for the largest selection. -chris PS Still saving up for a waterproof datascope (binocs+rangefinder+compass). Its that or insulate the attic this winter... *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************

Wind speed in ms-1 = 8.1 * sqrt(tan(angle of thread)) Wind speed in mph = 18 * sqrt(tan(angle of thread)) So next time you want to know the wind speed simply: 1. Raft up, attach sponsons, or stand up in your klepper (delete as appropriate) 2. Duck tape the thread and the protractor onto the end of your greenland style paddle, and hold it up into the wind. Hey presto!!!!! Never overestimate the wind speed you managed to paddle against again!!!!!!!! Who says you don't get useful information on paddlewise :-) Cheers Colin Calder 57º19'N 2º10'W PS - For an extra sophisticated instrument, build a spirit level into the protractor, or have your native paddle carver incorporate one into your paddle looms. PPS - For a super extra deluxe sohpisticated instrument, as above but also have your native paddle carver engrave the protractor scale directly onto your paddle and add a recessed hook for the thread. PPS - ALWAYS use an authentic native greenland style paddle or storm paddle. Under *** NO *** circumstances try this with a Western style paddle - the teeth of the wind will simply whip the paddle from your hands and laugh in your face. PPPS - Always keep your tongue firmly in your cheek and out or your wise ass PPPPS - There is a actually a plan out there on the net somewhere (on a kite flyers site) for an anemometer made with a ping pong ball, thread, and a card/plywood protractor marked in the beaufort scale. If anyone is interested I'll see if I can find the site. *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************

I'm not worthy.... *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************
