Now that GPS devices are cheap and plentiful we have the ability of measuring boat speed at specific distances. At the recently held 2007 US Nationals and Internationals a couple boats used a GPS device made by Velocitek to record their location and speeds. For more information on this device, visit their web site: http://www.velocitek.com/.
If you are interested in purchasing a Velocitek GPS device, HAPCO is a distributor. Contact Peter Duncan at SailFaster [at] aol [dot] com for more information.
