A ship's forward draft is 22'-04" and its after draft is 23'-00". The draft amidships is 23'-04". Using this information, where is the concentration of weight on the vessel?
• Relationship between draft readings and weight distribution along the length of the vessel • How increased draft in an area indicates where the ship is being pulled down by weight • Difference between forward draft, aft draft, and draft amidships and what they say about trim vs. weight concentration
• Compare the draft amidships with the forward and after drafts: is the ship deeper in the water in the middle or at the ends? • Ask yourself: where the draft is greatest, is that where the hull is being pressed down the most by weight? • Is this situation showing mainly a trim by the bow or stern, or is it showing a bending (hogging/sagging) effect with extra weight in a particular region?
• Identify where the largest draft value occurs (forward, aft, or amidships) • Distinguish between trim (difference between forward and aft drafts) and bending (difference between end drafts and midships draft) • Verify whether a greater midships draft than both end drafts indicates a concentration of weight in the middle or at the ends
