Volume of a two by four that's seven feet long = 1.5x3.375x12x7 = 425 cu.in Let's say 40% of the wood is left after carving = 170 cu.in. = 2.77 liters =2.77 kg = 6.1 lb of water displaced. Subtract from that the weight of the paddle. So around, idunno, 4 - 4.5 lbs (note: fully submerged)? That's _not_ a trivial force, but it ain't an inflated paddle float either. I find it amazing that somewhat less than that is used to provide stability by jamming the end of the blade under the deck lines. It's very well documented so I gotta try it and see.* Mike *going to a wedding this weekend. Maybe I should take the unfinished storm paddle, some sandpaper etc and get going on it. Think anyone would notice? *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
