[quote=Wolfman]Any of the Garmin Forerunner series work well and are waterproof to 2 m. THat is probably the one you saw. You may want to bag it to make sure it stays waterproof. There are others specific for sailing or other sports but they are generally way more expensive.
I wear my Garmin Forerunner 201 for running and on the boat on occasion. It is a pretty accurate little piece of equipment. And the software gives you a nice summary of how fast you were going, when, how far you went etc. and will give you velocity measurements while you are on the way (as you saw). Most of them also have a hear rate monitor you can wear so you can see how big your cojones were that day. :) It's is not a good navigation aid though since you have to post process the info after the fact and it doesn't display way point or things like that. I like it for training because it doesn't matter what I'm doing, running, biking, etc. it provides a lot of useful information.
