    OVERVIEW

    This unit provides an overwiew on the design process of motor yachts, focusing on high speed craft and relevant design issues.

    AIMS AND CONTENT

    LEARNING OUTCOMES

    This units aims to complete the student skills in the naval architecture field through the study of advanced topics specifically concerning the preliminary phase of the design.

    AIMS AND LEARNING OUTCOMES

    This unit aims to complete the student skills in the naval architecture field through the study of topics relevant to high speed craft, namely planing hull forms and surface piercing propellers.

    TEACHING METHODS
