Anchor Swing Report
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.
The values determined from this calculator should be used for educational purposes only. This calculator should not be used in determining the suitability of purchase, charter or passage on a boat. Instead the manufacturer should be contacted to obtain the boat's characteristics. The results of this calculator should not be relied upon for navigational purposes.
