Under sail and power: When a sailboat is using engine power it will display an inverted cone. When your gear is out extended distance the day shape is a single black cone, point up. Any kind of boat that is doing any kind of fishing needs to display this day shape.įishing with gear out over 150 meters: This is different from normal fishing. A boat that is constrained by draft cannot move in shallow waters.įishing boat: When a boat is fishing or trawling it displays two black cones points together. In fact, you cannot expect them to follow the rules of the road.īoat constrained by draft: A black cylinder is the day shape that indicates this. Don’t expect them to respect your signals. Not under command and restricted maneuverability mean give way. In both cases the boat is incapable of following rules. A white light between red lights signals this at night. One red light on top of another red light signals this at night.īoat is restricted in ability to maneuver: The day shape to indicate this is a ball on top of a diamond on top of another ball. Understanding how these day shapes works will let you understand when you need to give way.īoat not under command: The day shape for this is two balls. However, different day shapes can be displayed side-by-side. They should be keeping with the size of the vessel.ĭay shapes are often displayed vertically in a straight line from the mast head. If your vessel is less than 20 meters in length you can use shapes of a lesser size.the vertical distance between shapes she’ll be at least 1.5 m.a diamond shape shall consist of two cones as defined above having a common base.a cylinder shall have a diameter of at least 0.6 meters at a height twice its diameter.A cone shall have a base diameter of not less than 0.6 M and a height equal to its diameter.A ball shall have a diameter of not less than 0.6 m.Navigation regulations lay out the minimum size. The size of day shapes depends on the size of your boat. They can be combined together to create different meanings. There are four basic shapes in use with day shapes. When in use they should be hung where they are visible from all sides of your boat. They can be rolled or folded up for storage. They are similar to flags and many are made of heavy-duty vinyl. You can buy these shapes at most nautical supply stores. They also let you know when you need to avoid another vessel. When you can’t see navigation lights, day shapes let you know when to give way to other vessels. It is important to understand what day shapes mean to remain safe on the water. Unlike many flags or lights that vessels display the only color here is black. Day shapes need to be shown from sunrise to sunset. Some can identify a fishing vessel, or a sailboat under power, and so on. Different shapes indicate different things about the vessel. What is a Day Shape?ĭay shapes are geometric figures that relay something important about vessel navigation. Masthead light and running lights can only be seen at night, don’t forget. Likewise, they can communicate with you important information. The use of day shapes is how you can ensure that you are able to communicate what you were doing to other boats. Communication with other vessels is essential on the water.
