How coastal craft reached distant theatres

How were motor torpedo boats and related coastal craft moved between distant operating areas?

They could travel aboard larger ships in complete or kit form, but some carried extra fuel and self-deployed over long distances, including passages toward Malta.

Small coastal craft used several transport methods. Larger ships could carry complete boats or kits, while other craft received additional fuel and made long passages under their own power. Examples include movements from Britain to Malta and coastal boats accompanying convoys around Britain, across the Bay of Biscay, and through the Mediterranean. The label coastal did not prevent these vessels from participating in an ocean-spanning logistical system.
