Ben My Chree travels between the island and Heysham

The purpose-built Ben My Chree launched in 1998, and this week marked 590,000 miles on its regular route from Heysham, Lancashire, to the island.

The vessel carries passengers, cars and coaches on twice-daily trips.

Hamish Ross, Steam Packet's managing director said the company was "proud" of Ben My Chree's "superb service record."

He added: "It must be regarded as probably the most reliable ever owned by this company throughout its 175-year history.

"Ben My Chree is in a class of her own and has without doubt played a major part in our company's success in recent years."

Passengers on the 10,000th trip were upgraded and given a complimentary drink.
