The IMO Severe Wind and Rolling (Severe-Weather) Criterion is a stability criterion that has been developed to assess the dynamic stability of a vessel…

The theory behind the Severe-Weather Criterion is sound, and has a lot of merit. However, many of the new generation of high-speed monohulls are having trouble passing the criterion

• State the general topic and give some background

• Provide a review of the literature related to the topic

• Define the terms and scope of the topic

• Outline the current situation

As a result, it is believed that the formula used to predict the windward roll angle θ1 is flawed and over-predicts the rolling amplitude for high-speed monohulls.

• Outline the current situation

• Evaluate the current situation (advantages/ disadvantages) and identify the gap

• Identify the importance of the proposed research

• State the research problem/ questions

Thus it is desired to evaluate the actual rolling amplitude that these vessels will experience

• State the research problem/ questions

• State the research aims and/or research objectives

• State the hypotheses

• Outline the order of information in the thesis

In order to evaluate how the Severe-Weather Criterion is applied to high-speed monohulls, two vessels have been used as a case study
