Ship Stability for Masters and Mates Exercise 9 (a) Define 'coefficient of fineness of the water-plane'. (b) The length of a ship at the waterline is \( 100 \mathrm{~m} \), the maximum beam is \( 15 \mathrm{~m} \) and the coefficient of fineness of the water-plane is \( 0.8 \). Find the TPC at this draft. 2 (a) Define 'block coefficient of fineness of displacement'. (b) A ship's length at the waterline is \( 120 \mathrm{~m} \) when floating on an even keel at a draft of \( 4.5 \mathrm{~m} \). The maximum beam is \( 20 \mathrm{~m} \). If the ship's block coefficient is \( 0.75 \), find the displacement in tonnes at this draft in salt water. A ship is \( 150 \mathrm{~m} \) long, has \( 20 \mathrm{~m} \) beam, load draft \( 8 \mathrm{~m} \), light draft \( 3 \mathrm{~m} \). The block coefficient at the load draft is \( 0.766 \), and at the light draft is \( 0.668 \). Find the ship's deadweight. A ship \( 120 \mathrm{~m} \) long \( \times 15 \mathrm{~m} \) beam has a block coefficient of \( 0.700 \) and is floating at the load draft of \( 7 \mathrm{~m} \) in fresh water. Find how much more cargo can be loaded if the ship is to float at the same draft in salt water. 221 Gornct 5 A ship \( 100 \mathrm{~m} \) long, \( 15 \mathrm{~m} \) beam and \( 12 \mathrm{~m} \) deep is floating on an even keel at a draft of \( 6 \mathrm{~m} \), block coefficient \( 0.8 \). The ship is floating in salt water. Find the cargo to discharge so that the ship will float at the same draft in fresh water. 6 A ship's lifeboat is \( 10 \mathrm{~m} \) long, \( 3 \mathrm{~m} \) beam and \( 1.5 \mathrm{~m} \) deep. Find the number of persons which may be carried. 7 A ship's lifeboat measures \( 10 \mathrm{~m} \times 2.5 \mathrm{~m} \times 1 \mathrm{~m} \). Find the number of persons which may be carried.
