The Solway Firth could be Scotland's first coastal and marine park

The Solway Firth is one of the five areas currently shortlisted.

The road show will be visiting coastal communities up and down the west coast over October and November.

The first stop is Troon in Ayrshire and then on Saturday the vehicles will spend the day at the Harbour car park in Kirkcudbright.

The high-tech facilities on board will give local people the chance to learn more about the proposals and how they can have their say on the location and management of any future marine park.

Environment Minister Ross Finnie said: "There is a huge amount of interest, activity and diversity in our coasts and seas.

"It is crucial that coastal and marine based activity is managed in a sustainable manner which integrates socio-economic and environmental factors for the long-term benefit of our people and natural heritage.
