Scale: 1:48. Plan showing the inboard profile, upper deck, and lower deck for 'Vigilant' (1821), 'Basilisk' (1822), and 'Skylark' (1821), all 10-gun Cutters. The plan was later used to fit the 'Swift' (1821), a Revenue Cutter. Note the alteration to the inboard profile for 'Basilisk', converting her to a ketch, as per the order of March 1835. The plan also shows, at a scale of 1:24, a section illustrating the method of fixing the beams to the sides of the ship.
