I know I sound like an old farte, but anchoring a small, narrow boat at both ends is a dangerous thing. Notice, if you anchor a canoe at one end, and rather suddenly lean and dip one gunwale deeper than the other, the boat responds by "sliding" away from the low gunwale. Anchor both ends and the boat responds by filling and dumping you. I'd rather sit in a full canoe than a full yak. And, I rather not swamp anything I'm riding in. Think hard before you restrain BOTH ends. piper
