The original Sula started trips around the Bass Rock in 1970, skippered by local fisherman Fred Marr, with his son Chris helping out.  A larger boat named Sula II was purchased and took over the sailings in 1972.
Sula II was built in Norfolk in 1964 from the finest Honduran Mahogany, she worked as a fishing vessel 'Caroline' until she was purchased by Fred Marr in 1972, and moved to North Berwick.  Fred used the boat initially for a combination of Lobster fishing and passenger trips around the Bass Rock, but passenger trips became the main use.  Fred's children Pat and Chris Marr continued the family business with the Sula II until the business was sold in 2011.  Sula II continued sailings until 2018 when due to more stringent MCA rules being introduced she would not longer be allowed to carry passengers out of North Berwick.  She was sold and now operates from Lulworth Cove in Dorset.
Sula III - To preserve the Sula business into the future a new vessel was needed, at the end of 2018,  Sula III was commissioned.  She was designed by Argyll based Murray Cormack Naval Architects  and built by Alutec Marine in Balcardine near Oban on the west coast of Scotland.  She is scheduled for delivery in early 2020 and will ensure that Sula boat trips can continue as North Berwick's premier boat operators long into the future.
