Interface: BoatDef ​

Defined in: packages/sim/src/vehicle-classes.ts:56

What makes a class a boat (boat.ts): it floats on six points of its hull's bottom instead of standing on wheels (a boat has no axles, axles: []), its propeller pushes only under water, a rudder turns it, its keel holds it against sliding sideways.

Properties ​

dragAcross ​

dragAcross: number

Defined in: packages/sim/src/vehicle-classes.ts:67

Its drag across itself, the keel's (1/s): the share of its sideways slide it loses each second.

dragAlong ​

dragAlong: number

Defined in: packages/sim/src/vehicle-classes.ts:64

Its drag along itself: a share of its speed (1/s) and of the square of it (1/m) lost each second, in the water.

dragQuadratic ​

dragQuadratic: number

Defined in: packages/sim/src/vehicle-classes.ts:65

draught ​

draught: number

Defined in: packages/sim/src/vehicle-classes.ts:60

How deep it sits at rest (m): from its keel (the chassis box's bottom) to the waterline.

lean ​

lean: number

Defined in: packages/sim/src/vehicle-classes.ts:69

How far it leans into a turn: the roll it is pushed to per metre per second of speed times radian per second of turn (rad).

planing? ​

optional planing?: number

Defined in: packages/sim/src/vehicle-classes.ts:71

The speed from which it planes (m/s): its bow lifts and its drag falls; none for a displacement hull.

propulsion ​

propulsion: BoatPropulsion

Defined in: packages/sim/src/vehicle-classes.ts:58

What drives it: an outboard engine, an inboard diesel, oars or pedals (what the client sounds and names).

stroke? ​

optional stroke?: number

Defined in: packages/sim/src/vehicle-classes.ts:73

It is rowed: its push comes in strokes, stroke seconds apart, by the tick.

turnRate ​

turnRate: number

Defined in: packages/sim/src/vehicle-classes.ts:62

How fast it turns at full rudder once it carries way (rad/s).
