How Calculate and Draw Anchor Swinging Circle ⭕️ ⚓️
The Anchor Swinging Circle is the area in which an anchored vessel can swing due to changes in wind, current, and tide. It is also known as the “swing circle” or “swinging room.” The size of the swinging circle is determined by the length of the anchor chain or rode, as well as the depth of the water and the distance between the vessel and the anchor point. It is important to ensure that there is sufficient swinging room when anchoring to avoid collisions with other vessels, underwater hazards, or the shoreline. Additionally, local regulations may limit the size of the swinging circle or require vessels to anchor in designated areas.
Ship’s length (Bridge GPS antenna to fwd) + (How many shackles x 27.5m)
FOR Example :
= 6 shackle on deck and (bridge GPS antenna to fwd) is indicated by L = 100m
= 6 shackle +L
= 6×27.5m +100
= 265m
= (265/ 1852 ) nm
= 0.1431nm
= (0.1431×10) cable at one NM is equal to 10 cable
= 1.431 cable
