Freeboard calculation

(At the ship design stage)

Introduction

Calculation of the freeboard is one of the basic and primaries that are to be done at the initial ship design stage, where it is not absolutely necesary to be quite exact. An approximate and quick calculation is therefore very suitable. After a brief concepts reminder I enclose a form where main ship dimensions are to be input by the user and freeboard results are displayed.

Cruising ships

An approximation to their dimensions

In my post of April 8, 2010 in this blog, entitled "Preliminary dimensioning of merchant ships," I included a procedure to calculate a first approximation of most significant particulars of 9 different merchant ship types, but I omitted a very important one, which is the passengers cruising vessel (hereinafter Cruising Vessel (CV)). One friend suggested me to extend the procedure to include the CV, because of the interest presently have these vessels, which are among the few that can successfully compete in Europe with eastern shipyards. Following this suggestion I have prepared a preliminary CV's dimensioning procedure, but I warn from just now that the data I base on have been obtained from Internet sites and some of them are not quite reliable, as I shall comment further on.
