Calculate the Fresh Water Allowance & Dock Water Allowance II Change in Ship's Drafts due t

In this video, it shows how to calculate the Fresh Water Allowance & Dock Water Allowance. It includes how to determine the change in the Ship's drafts due to the changes in water Density. Find the Relative Density and determine the arrival draft from salt water to fresh water & vice versa. Determine the arrival draft from dock water to salt water & vice versa.

Fresh Water Allowance (FWA) is the number of millimeters by which the mean draught changes when a ship passes from salt water to fresh water, or vice-versa when the ship is loaded to the Summer displacement.
