Vital Spark
The Vital Spark is the best known name associated with Clyde puffer boats, having been used in the fictional works created by Scottish writer Neil Munro. Several Clyde puffers were used in televised versions of Munro's stories and subsequently for purposes such as events and tourism. As the numbers of surviving puffers diminished the boats Auld Reekie and Eilean Eisdeal were both portrayed as Vital Spark.
