Solution: The speed of the ship is equal to the combined speed along the rope direction and perpendicular to the rope direction. According to the law of parallelogram, if there is a V-ship cosθ=v, then V-ship = VCOS θ.

A, as can be seen from the above, the speed of the car v 1 is always less than the speed of the ship v2, so A is wrong and B is correct;

C, if the car is moving at a constant speed, the ship will accelerate with the increase of the included angle θ, so C is right and D is wrong;

So: BC.
