Available in ash, black cherry, butternut, and walnut - 32" or 34" long Kit Contains: Thwart Silicon Bronze Carriage Bolt 3/16 X 2" (4) Silicon Bronze Hex Nuts 10-24 (4) Silicon Bronze Flat Washers #10 (4) The thwarts MUST be mounted at the BALANCE POINT of the canoe (which is not the center-although close!) A builder might, at a future date, decide to change the thwart for a carrying yoke; this will prove easy as our center thwarts and yokes have the same end profile so are interchangeable. Canoes LONGER than 16'-consider a narrow second thwart 5" approximately aft of the bow seat - see image of the Nomad. The narrow thwart must be installed BEFORE balancing the canoe and installing the centre yoke or thwart.
