 The first two rolls were done with roughly the same amount of detail while the lesser rowbarges ( essentially small galleys ) were done more hastily . The first two ships of the first roll , the Henry Grace à Dieu and the Mary Rose , have traces of a grid pattern , indicating that they were transferred from a different drawing while the rest are done in freehand . Overall , the ships follow a formula depending on the type of ship . The exceptions are stern galleries of some of the galleasses and the figureheads of the Mary Rose , Salamander and the Unicorn , the latter both captured from the Scots in 1544 . The prominent exception is the Galley Subtle placed in the middle of the second roll . It is more consistent in type with Mediterranean @-@ type galleys than the galleasses and small rowbarges , and features a considerable amount of detail not present in the other ships . It is the only ship where any crew is visible , in this case rowers behind <unk> as protection from enemy arrows and an overseer wearing " a bonnet , full skirted armorial doublet and baggy breeches " holding a stick or baton , as if beating the time of the strokes of the rowers .
