发明名称 Kayak paddle
摘要 A wood kayak or canoe paddle having a rubber-like shock-absorbing abrasion-resistant flexible strong strip of urethane rubber adhered to the tip of each blade, and preferably extending also along the opposite edges of the blade, to strengthen the blade and reduce the likelihood of damage to the blade by rocks sand or other solid abrasive material during paddle use. Each paddle face is reinforced adjacent the rubber-like strip by a thin layer of carbon fibers lying parallel to the strip and each entire paddle face is covered with a thin layer of glass fabric embedded in a water resistant flexible coating. The paddle shaft is laminated of ash and sitka spruce with reinforcement by high tensile strength fibers at the lamination interfaces and added ash laminations adjacent the shaft extension in the paddle blade.
