Your drafts are: FWD 24'-09", AFT 27'-02". Use the blue pages of the Stability Data Reference Book to determine the vessels displacement if you are in salt water.
• Mean draft calculation from forward and aft drafts • Using blue pages hydrostatic tables to read displacement for a given draft • Effect of salt water vs. fresh water on displacement readings
• How do you correctly find the mean draft from different forward and aft drafts? • Once you have the mean draft, where in the blue pages do you look to find the corresponding displacement? • Do you need to apply any density correction, or are the blue-page displacements already based on salt water?
• Be sure you computed the mean draft correctly before entering the tables • Confirm you are on the correct vessel and condition hydrostatic page that matches these drafts • Verify whether the hydrostatic table you are using is labeled for salt water so you know if a correction is needed or not
