Once a ship had been built and launched she then had to be out-fitted, and then complete sea trials
before being handed over to her new owners, who would look to have that ship at sea, as long as possible to pay for her build costs and of course to make the company good profits.
To this end one company may have had no requirement for a particular ship after a time and would then sell her on just like any other disposable commodity.
Hence a ship may have had a few owners and would go through many changes and names during what was hoped for a long and successful working life.
The small harbour tug BUSI was an order from the very well known company of Beira Boating Company.
Another one of many such tugs to be built at the Leith Shipyards of Henry Robb, this tug was built and launched just after the firm had taken over another famous shipbuilders who had specialised in the building of many, many tugs going back to 1980
The company of Cran & Somerville was taken over by the Henry Robb shipyard in 1926.
