Bill - thanks for the info!! Here is some info on salmon sharks: researchers put satellite tags on dozens of us salmon sharks, starting in summer 2002. They grow large -- Salmon sharks grow to 10 feet long, are stout -- almost 900 pounds of muscle. And FAST -- one of the speediest! The U.S. Navy's has clocked Salmon sharks at nearly 50 mph.!! That may be just a little faster than the Star craft Super sport you use !! Obviously, they are predators, whose favorite food is Pacific salmon!
