Controlling Hull Generation

Within the parameters group are a number of control which are used to control how the surface is updated.

Update Manually updates the surface after any changes to the parameters
Interactive Update Checking this box causes the surface to be automatically updated after any changes to the parameters
Default Returns the parameters to the initial values

Hull Generation Parameters

The parameters group is used to specify all of the parameters used to generate the surface.

Loa Length over all
Lwl Waterline Length
Ovh Length of the forward overhand. i.e longitudinal distance from the forward perpendicular to the extreme forward end of the vessel
BMax Maximum breadth of the hull
Bwl Waterline breadth of the hull
BTransom Breadth of the hull at the deck at the top of the transom
Tc Draught of the hull
Cp Prismatric Coefficient
Cm Midship Section Coefficient
LCB Longitudinal centre of Buoyancy
Cwp Waterplane Coefficient
Lcf Longitudinal Centre of Floatation
FreeBow Freeboard at the Bow
FreeMid Freeboard at the midship section
FreeAft Freeboard at the top of the transom
BowCurve The angle of the tangent of the stem curve at the top of the stem and at the waterline.
Forefoot The distance the hull drops below the waterline at the bow.
TransomAngle The sloping angle of the transom. 0 degrees creates a vertical transom.
FlareAngle The flare angle at the aft perpendicular.
