There is always some thing, just don't deplay it deep when your close to shore. I've started contructing my skeg. i found some tougher tubing for the cable hosing, Synflex, brake hose for trucks. I'm going to use brass fittings to ease replacement of the hose if it wears or the cable if it becomes damaged.

Later, gotta get some sleep so I can tackle more on the boat before the weekend is gone.
