Load the morning lighter before the tide turns. Mind the swing.

How to work her

Ten-odd lots on the quay, one lighter alongside, four minutes of tide. Hook each lot by its lifting eye, set it down on the lighter's deck and open the grab.

The levers

Slew the jib	`AD` or `←→`	Left lever, sideways
Jib up / out	`WS` or `↑↓`	Left lever, up and down
Haul in / pay out	`QE`	Right lever
Grab shut / open	`Space`	Brass button
Horn: end the shift	hold `H`	Hold the horn
View	`C` · drag the scene	Camera button
Sleep · collision view	`Z` · `B`	Side buttons
Tea break · sound	`Esc`/`P` · `M`	Side buttons

A slews her anticlockwise and D clockwise, as seen from above. Let go of a lever and she eases to a stop.

The pay

When the horn goes you're paid for every lot aboard, less damage and salt water, for the height of the stack, for how level she sits, and a bonus if nothing went in the harbour. Turn her over and you're paid nothing. Get everything aboard early and the minutes you save are paid too.

From the old hands

A swinging load follows the jib head. Ease after it and the swing dies.
The piano is heavy at the iron end. It hangs nose-down.
The lighter lists toward her load. Spread it.
Drop a lot in and it floats or sinks by its weight. Floaters can be fished out.

Tea break

Kettle's on. The tide isn't waiting, but it'll wait for this.
