Scale: 1:32. Navy Board skeleton model of a yacht, possibly royal (circa 1690). The model is decked and rigged with the sails (modern) set. It is flying three flags: union on the jackstaff, royal standard on the mainmast and ensign on the ensign staff. It was re-rigged at the Science Museum in the early 1930s with its original spars. The modern sails and flags (later removed) were added.

This model probably depicts an actual vessel which would have been privately owned. It is doubtful whether it depicts a Royal Yacht as they were ketch rigged (two-masted) at this date. At the above scale, the length would be 74 feet by 21 feet in the beam, with a tonnage of 130 burden. The model is an excellent example of late 17th century craftsmanship using the typical hard fruitwoods such as apple and pear, as well as boxwood for both the decking, planking and the carved decoration.
