The royal yacht built for The Duchess of Kingston was built by the shipbuilders JM Hillhouse of Bristol in the late 1770’s. This type of vessel seemed to retain many older, more classical features, compared to those built for the Royal Navy, making the yacht look more a product of the late 17th/early 18th Century.
The dimensions on the original plans are as follows:
Keel length – 68 Feet
Range of deck length – 81 Feet Moulded Breadth – 24 Feet
Depth of hold under beams – 10 Feet Burthen in tons – 206
