y-axis is positive right on the page.
y-axis is positive up on the page.
Assume vessel is lying parallel to x-axis with an arbitrary, longitudinal base-line at y = 0; z = 0.
Prow of the vessel is at x = 0, z = 0; y position of the prow is irrelevant.
Assume foil wings are rectangular and positioned at the bottom of the struts.
Assume elevator is physically attached to the bottom of the rudder.
Assume elevator angle is changed by pivoting the rudder about a horizontal axis at the the top of the rudder leading edge.
Assume propellor force acts in a direction parallel to the base line.
N.B. The dimensions below do not describe the construction of the vessel.
They are used to define the directions of the various forces acting on
the vessel and the points at which they are applied.
The magnitude of the forces will be calculated from supplied tables.
Phase 1 of the development considers the vessel moving in a straight line.
