ANCHOR SWINGING ROOM CALCULATION
The following is the formula used to calculate Swing Radius of a boat at anchor.:
Swing Radius = LOA + [ ( RODE ) 2 - ( DEPTH + FREEBOARD)2 ] 1/2
LOA: Overall length of the boat, including any additions or extensions from the stern
RODE: The length (line to the anchor) of the rode from the bow pulpit to the anchor.
DEPTH: The water depth over the anchor.
FREEBOARD: The distance from the deck at the bow pulpit to the water.
Note all measurements of length and distance must be in the same units.
