Exam Question
The ratios of length, breadth and draught of a vessel are 18.5 : 2.5 : 1. The water plane area coefficient is 0.73 and the TPC is 0.77 more in sea water than in fresh water. Calculate the beam of the ship and TPC in fresh water. (16)

Reference Answer
### Objective
To calculate the beam (breadth) of the ship and its Tonnes Per Centimetre Immersion (TPC) in fresh water, based on the provided dimensional ratios, waterplane area coefficient, and the difference in TPC between sea water and fresh water.
### Given Data and Assumptions
* **Ratios:** Length : Breadth : Draught (L:B:D) = 18.5 : 2.5 : 1
