The DEEP DRILLER, while loaded as shown in the Sample Load Form #5 (Survival) loads an additional 137.88 long tons. The resulting trim by the stern is 2 feet and the list to port is 3 feet. What is the draft at the port forward draft mark?
• Using the Sample Load Form #5 (Survival) to read the original drafts at each draft mark • How trim by the stern changes forward and aft drafts (relationship with vessel’s length and trim in feet) • How list to port affects port and starboard drafts at the same end of the vessel
• What were the original drafts at the port forward and port aft marks before adding 137.88 long tons? • If the vessel trims 2 feet by the stern, will the forward draft increase or decrease, and by about how much at the forward mark? • If the vessel lists 3 feet to port, will the port drafts be deeper or shallower than the starboard drafts at the same end?
• Be sure you are using the correct initial draft from Sample Load Form #5 at the port forward draft mark • Check that you apply trim along the length (forward vs aft) and list across the beam (port vs starboard) separately • After applying trim and list, confirm that the resulting mean draft is consistent with the added weight (137.88 LT) shown on the loading form
