We were stuck with a slow boat and a ten day journey.

My mother is a senior citizen, and even she says it's a slow boat.

Walk to the ferry dock and take the slow boat.

If not, he would be sent home on a slow boat.

I was told that the slow boat would arrive a half hour later.

About 9:30, 2 slow boats full of people approached the dock, but no one got off.

Didn't even ask me before she put us all on the slow boat to nowhere.

They'll have you on a slow boat to China with a needle in your arm.

The idea being that a "slow boat to China" was the longest trip one could imagine.

I'd like to get you on a slow boat to China?
