The Difference Between a Liner and a Tramp Service
The main difference between a liner and a tramp service is that a liner has a fixed schedule and ports of call, while a tramp service does not. A liner will typically sail on the same route at the same time each week or month and will call at the same ports in the same order each time. On the other hand, a tramp service does not have a set schedule or ports of call. Instead, it will go to wherever there is cargo to be transported.
