A guide to fishing vessel stability / Руководство по устойчивости рыболовного судна

Книга на английском языке
Stability is the force of buoyancy from the underwater parts of a vessel combined with the weight of its hull, equipment, fuel stores and load. These forces are affected by changing weather conditions and ocean swell. The stability of your vessel changes throughout your trip.
