When mooring starboard side to, with no wind or current, the approach angle should be as _________________________ as possible. Twin-Screw Boats

• A. as shallow as possible
• B. as steep as possible
• C. as wide as possible
• D. as slow as possible

Answer: (A)

When bringing a vessel in to moor beside a dock in still water, the path you follow toward the quay should be almost parallel to the dock line. That is what a shallow approach angle accomplishes. Moving in with a very small angle keeps the hull close to the dock and allows you to ease the vessel into position without the bow or stern colliding with pilings or fenders. It also makes line handling and fender placement easier, since you’re not trying to stop a large sideways swing at once. Having two propellers helps with this maneuver because you can fine-tune thrust on each engine to hold a steady, near-parallel approach and make small heading adjustments without rushing the boat or losing control in still water. Steeper angles would bring the bow into contact sooner and harder, making control more challenging. Angles that are too wide would cause the boat to strike the dock or overshoot the intended position. Speed alone doesn’t define a good approach; the angle is what determines how smoothly you can settle in alongside the dock. Therefore, the best approach is as shallow as possible.
