The shoulder is a ball and socket joint with a large range of movement. Such a mobile joint tends to be more susceptible to injury. Shoulder pain can stem from one or more of the following causes: Strains from overexertion.
The gunwale (/ËÉ¡ÊnÉl/) is the top edge of the side of a boat. Originally the gunwale was the gun ridge on a sailing warship. This represented the strengthening wale or structural band added to the design of the ship, at and above the level of a gun deck.
Third, the outer gunwale protects the edge of the hull from damage and deflects water from entering the boat when waves splash against the sides. The gunwales also serve as a convenient hand hold when the canoe is being carried or lifted. If you choose to radically modify the gunwale design on your canoe, make sure that it can still adequately fulfill these design functions.
