Dynamic trimming is a method

Methodology

Methodology is generally a guideline for solving a problem, with specificcomponents such as phases, tasks, methods, techniques and tools . It can be defined also as follows:...

 of operating seagoing vessels in a way that ensures minimum water resistance

Drag (physics)

In fluid dynamics, drag refers to forces which act on a solid object in the direction of the relative fluid flow velocity...

 in all circumstances. The method is based on collection and multidimensional analysis of exact real-time data on vessel attitude.

The method is based on automatized retrieval of data from operational vessel management applications and purpose-built sensors using sensor network technology. The core of the method is a multidimensional analysis model, which continuously calculates the key forces affecting the vessel attitude.

The method is aimed to help officers ensure their vessels are operated right. The key metrics are brought to vessel officers in a graphic form to facilitate decision-making.
The data helps vessel officers to optimize trim

Sailing ballast

Ballast is used in sailboats to provide moment to resist the lateral forces on the sail. Insufficiently ballasted boats will tend to tip, or heel, excessively in high winds. Too much heel may result in the boat capsizing. If a sailing vessel should need to voyage without cargo then ballast of...

at all times, thus minimizing water resistance.
