Tow a 24' MasterCraft on a triple-axle trailer out of the neighborhood and back it straight down the boat ramp into the lake.
Steering: drag the slider, or ◀ ▶ on a keyboard.
Throttle: tap & hold FWD / REV, or ▲ ▼.
Remember: while backing up, the trailer turns opposite your steering input at first — small, patient inputs win.
