For the purposes of loadline marks, freshwater is considered to have a density of 1,000 kg/m3 (62 lb/cu ft) and typical seawater 1,025 kg/m3 (64 lb/cu ft). Freshwater marks make allowance for the fact that the ship will float deeper in freshwater than saltwater. A ship loaded to her fresh water mark in fresh water will float at her summer mark once she has passed into seawater at the same displacement.
