We saw a patrol boat out on the water earlier.

He turned and called an order down to the patrol boat.

The patrol boat moved out from under the tree, but not far.

The patrol boat turned in another large S and moved on up the bay.

The patrol boat was paid off on 6 January 1994.

The problem was that they didn't know how far away the patrol boats were.

As we rose in the air, I saw a patrol boat some distance away turn and head for us.

You can call up and ask for a patrol boat to clear the channel.

I'm going to ask for a couple of fast patrol boats to be sent out here to meet us.

Their lead over the patrol boat was down to two hundred yards.
