Scale: circa 1:36. A contemporary full hull model of a hoy (circa 1750). The model is decked, equipped and rigged with the sails set. The sails, with reefing pennants on the mainsail, were added by the Museum. The model is not particularly well executed: both the beam and depth are probably too great in comparison with the length. It was previously in the Mercury Collection and was acquired for the Caird Collection in 1929. The vessel measured 56 feet in length by 21 feet in the beam, displacing approximately 100 tons burden.

Hoys were small coastal sailing vessels, usually displacing up to about 60 tons. They were sloop rigged and the mainsail could be fitted with or without a boom. They did a variety of work for both the merchant service and Royal Navy. Some were specially built to carry fresh water, gunpowder or ballast; others were in the Revenue service or employed in such tasks as laying buoys or survey work. They could be hailed from the shore to pick up goods and passengers and it is possible that their name may have derived from this procedure. English hoys tended to be single-masted, whereas Dutch hoys had two masts.
