# VehicleWaterPlaning

> Talos next · Since 0.7

Planing: hydrodynamic lift on the hull's bottom rising with speed, so a fast hull rises out of the water and the water's drag on it (the `buoyancy` drag, which acts on the submerged hull) falls.

## Fields

| Field | Type | Required | Default | Allowed values | Description |
|---|---|---|---|---|---|
| `position` | `Vec3` | no |  |  | Where the lift acts, on the hull's bottom, in the body's local space, metres before scale. Absent: the middle of the chassis collider's bottom face. |
| `lift` | `number` | yes |  |  | Lift per (m/s)² of forward speed through the water once fully planing, N·s²/m², 0 or more. |
| `minSpeed` | `number` | no | `3` |  | Speed through the water in METRES PER SECOND where planing starts, 0 or more. Defaults to 3. |
| `fullSpeed` | `number` | no | `9` |  | Speed through the water in METRES PER SECOND where planing is complete, above `minSpeed`. Defaults to 9. |
| `maxLift` | `number` | no | `0` |  | The most lift, as a fraction of the vehicle's weight, 0..2. Defaults to 0.6. |
| `size` | `number` | no | `0` |  | Height of its wet band, metres, greater than zero. Defaults to 0.3. |
