Wayne Horodowich , one of the excellent speaker/instructors at the 2003 Gulf of Maine Sea Kayak Symposium last year said that the foam paddle floats were standard issue in certain Canadian waters where temperatures were just too cold to make an air tight lip lock on a blow-up padde float. Having been so cold that almost nothing works, including my lips, I can see where the foam floats could be a life saver. Personally, I paddle when the weather/water is tolerably warm and so use an air bag paddle float. If I paddled in the winter, I would use a foam float for obvious reasons. Tom Pumkin/white Explorer
