"Basil Jet" gurgled happily,
sounding much like they were saying:

A better solution is for normal buses to drive onto a raft. The raft
would be owned by the bus company, it would only carry one bus, and the
driver reaching out the window of the bus would steer it and lock it to
the quay. There would be no engine on the raft, but the wheels of the
bus would turn rollers which were attached to a screw or propellor.

There's nothing new under the sun...
