Collision between two vessels is caused by various conditions. In fact, I can point out that there is not enough look out and that the various actions taken to avoid collision are not done in ample time. About 30% of the vessels that collided caught sight of the other vessel at a distance less than 3 times the length of the ship, and about 70% of the vessels that collided took action to avoid collision at a distance less than 3 times the length of the ship. We think that to avoid collision, we must keep good watch and that any action against it should be taken in ample time.
