I think that all the portable sundials that have been invented and used can be used on a ship or a boat but I don't know any sundial SPECIFICALLY designed for this use.
The only sundial that I know that was specifically designed to be used on a mean of transport was built some years ago by the Italian dialist Giacomo (Gim ) Bonzani (http://www.gimbonzani.it/index.html) It was fixed on the wall of a wagon of the small railroad "Ferrovia Vigezzina" from Domodossola (Italy) to Locarno (Switzerland) ( www.vigezzina.com) It marked the exact time only when the train stopped in the station of Villette (village where Bonzani lives ). The sundial had dimensions of around 40x30 cm (16x 12 inches ) . It was removed by its position for safety reasons even if the gnomon stuck out only few cm.
