1. **Problem Statement:** We are given two sets of ship parameters and asked to find the effect of GM (metacentric height) and righting moment at a certain heel angle for the first

1. **Problem 1:** Calculate the moment of inertia of a rectangular waterplane 42m long and 9m wide about axes parallel to the beam. - The beam is the width direction, so the axis i

1. **State the problem:** We need to find the distance from amidships where a load can be added without changing the draft aft (T_A). 2. **Given data:**

1. **State the problem:** A ship 55 m long has drafts 3.65 m aft and 2.75 m forward. Two loads (27 t and 70 t) are added at 18 m aft and 19 m forward of amidships respectively. We

1. **State the problem:** We have a ship 140m long with drafts 4.85m aft and 4.25m forward, and LCF 1.9m forward of amidships. 2. **Given data:**

1. Statement of the problem: A ship of length $L = 110\text{ m}$ floats on an even keel with draft $4.85\text{ m}$ and its LCF is $1.0\text{ m}$ forward of amidships. 2. A load of

1. Problem statement: A ship has a target mean (load) draft of $9$ m, current forward draft $8.9$ m and aft draft $8.5$ m, and the only spaces left for cargo are no.2 at $+50$ m (f

1. Problem: A ship has a load draft of $7\text{ m}$ and currently reads $T_F=7.1\text{ m}$ and $T_A=7.5\text{ m}$. 2. Compute the current trim: the trim (stern minus bow) is $T_A-T

1. Statement of the problem: A ship has a draft at the LCF of $8.0 m$ and a trim by the stern of $0.6 m$. A mass of $200 t$ is added $30 m$ aft of the LCF.
