A one-off cruise is an event organised by a particular group of people or club which would usually be advertised through cruise websites. The final destination of the cruise is often kept secret; it is known only to the convoy leaders in an attempt to keep the cruise unknown to the police. until there are a large enough numbers of people at the cruise to make it difficult to disperse.
One-off cruises tend to be larger than meets, but larger meets may have magazine attendance. This type of cruise is increasing in recent times due to increased police interest in regular, established cruises.
Some large cruises operate a “convoy-only” policy.
