vehicles: a boat nobody rows is moored where it was called or left - its hull put back on the mooring (home_x, home_z, home_yaw) whenever it strays, and no wind on it; the wind drifts only a rowed boat

A called boat and one got out of drifted across the lake on the wind (the user's play of the bundle).
The tests hold a boat at its berth in a full wind for eight seconds, and one dropped out on the lake
where it was left.
