**Quiet Down **
It all starts with the proper craft. The quietest canoes are made of acrylonitrile butadiene styrene, or ABS, a common material for durable, general-purpose boats. (Royalex is a familiar brand of it.) Fiberglass is next best, as long as your stretch of stream is free of hull-shredding rapids. Far worse are aluminum canoes, which hang up easily on rocks and often make you sound as if you're paddling a tambourine. If you must float in a metal boat, dampen the decibels by lining it with outdoor carpeting or old carpet samples. No matter what you paddle, soundproof the rest of your gear: zipper pulls, pockets full of shells, even the tiny metal tabs on glove cuffs will produce clinks and clanks loud enough to send a preening pintail scrambling.
