Development of Bezier Chine

Describes the three types of Bezier Chine hulls and how they came to be.  Read 'True Round Metal Boat Building - Bezier Chine Design' for a full understanding of the construction method.

Required Drawings

To convert an existing Double Hard Chine hull to a True Round hull specfic information is required.  This section describes the Lines drawing, Table of Offsets, and the Construction Plan and Profile drawings.Required Drawings.

Conversion Process

Describes the conversion process, which is broken down into two steps.  The first step is the conversion of the hull form to True Round.  The second step is to correct the Displacement and Center of Gravity as related to the Design Waterline.

Hull Form - Hydrostatics - Coefficients

In this Chapter I review the true round hull form and compare the hydrostatics ans coefficients of both hull forms.


The stability of both designs are compared to each other.


The resistance of both designs are compared to each other.

In the last chapter I will leave it up to the Reader to make the final Analysis based on all the aboved.

Speed Predictions

Both design are calculated here and presented Charts and Graphs.  From these calculations a race will be run over a 10 mile windward-Leeward course
