This is fairly easy to get, although the last section is a bit frustrating (when you jump and you have both a hawk and a flying fish ready to knock you off the boat). What I did was: slow down and shoot the hawk during the jump over the obstacle, then quickly jump over the fish.
Just remember that you can shoot, and not to touch anything except for money (if you're not confident, or if you have heaps, you can skip the cash if it looks tricky to get.) Once you clear the hawk+fish combo, you're home free.
