Check draft and trim readings and calculate liquid volume in simple tanks.

Summarize observed forward and aft drafts as a simple arithmetic mean and signed draft difference.

Calculate the arithmetic average of forward and aft draft readings without vessel-specific corrections.

Identify trim by stern, trim by bow or even keel; optionally calculate gradient and angle using a reference length.

Compare aft and forward draft while retaining the sign needed to identify trim direction.

Calculate total capacity, liquid volume, remaining volume and fill percentage for a rectangular tank.

Calculate capacity and current liquid volume for a vertical, flat-bottomed cylindrical tank.
