CUTAWAY

THE SIDES

Sides with tumblehome are comfortable to paddle. Frare ones help to keep waves outside. Plumb is a compromise

THE BOTTOM

A round bottom is not very stable and is used mainly in races. A flat bottom is good for big charges. An arch bottom is a good and usual compromise. A "V" bottom is also good for speed, but is difficult to turn

SIDE VIEW

A high rocker canoe is good for quick pivots and turns in a river, a straight keel is berrer suited for speed on flat water
