519. The DEEP DRILLER, at 58.0 feet draft in sea water, places 200 long tons on board. What is the new draft?

Adding 200 long tons to the DEEP DRILLER increases the draft by 1.45 feet, resulting in a new draft of 59.45 feet. This is calculated using the vessel's tons-per-inch immersion (TPI), which is approximately 11.5 long tons per inch at a draft of 58.0 feet. Adding weight always increases draft; decreasing draft or a drastically large increase are unrealistic.
