Alexander Robertson & Sons was a boatyard in Sandbank, Argyll and Bute, Scotland, from 1876 to 1980. The yard was located on the shore of the Holy Loch, not far from the Royal Clyde Yacht Club (RCYC) at Hunters Quay, in the building that is now the Royal Marine Hotel, which was the epicentre of early Clyde yachting. Alexander Robertson started repairing boats in a small workshop at Sandbank in 1876, and went on to become one of the foremost wooden boat-builders on Scotland's River Clyde. The "golden years" of Robertson's yard were in the early 1900s, when it started building some of the first IYRU 12mR & 15mR (Metre Class) racing yachts. Robertson's was well known for the quality of its workmanship and was chosen to build the first 15-metre yacht designed by William Fife III (Shimna, 1907)
