The "SILVER" is identical to the "JACK" except for materials used. The great value of the "SILVER" model is accomplished by using 25% fiberglass in place of some carbon. This is still Chinook's most innovative design featuring an oval shaft creating natural hand indexing for proper paddle position. The oval shape also allows us to make a very light shaft with incredible control over stiffness. This paddle has superior feel and performance. The Silver incorporates our smaller blade design for easier paddling or a higher cadence. Carbon content plus oval design provides best control of flex to strength to stiffness properties. Dihedral blade face provides smooth directional paddling stability. Ergonomic handle is extremely comfortable and simplifies proper paddle direction. Max length: 87". To be cut to your desired length. Blade dimensions 16" x 7.5" (82 square inches) at 10 degrees. Weight- 1.25 lbs. One year warranty.
