The Lancashire nobby was primarily a shrimp
trawler towing
beam trawls sized for common "brown shrimp" (
Crangon crangon), "pink shrimp" or "Aesop prawn" (
Pandalus montagui), or
flatfish. The nobby ranged in size from about for single-handed boats and from for two-man boats. They were all
pole masted cutters with
gaff topsail. In the north west of England the
Morecambe Bay nobby emerged about 1840 as the local type. Houldsworth illustrated them as a
sloop rigged craft with a square tuck
stern A report in the Lancaster Gazette of 7 November 1840 indicates that
Southport smacks were also fishing in Morecambe Bay, providing another progenitor of the nobby. The design evolved from earlier straight-stemmed, long-keel boats into a beamy shallow hull with a pronounced reverse curve in the midship section and a cut away forefoot. The square tuck stern changed into an immersed elliptical counter, either by evolution or adoption of the Southport form, the change being complete before 1880. All of the boats had wide side decks and a long cockpit, about a third of the beam in width, with low freeboard and a low rail to facilitate lifting the gear on board. These shrimp boats, about , were fast and handy in the shallow waters of Morecambe Bay. The larger boats were called “prawners”, though they were actually used to catch pink shrimps (
Pandalus montagui). In addition to the larger prawner (called "sprawner" at Morecambe) a subtype called "bay boat" developed for the holiday trade. The bay boat had a shallow draft so it could operate around
Grange-over-Sands at the head of Morecambe Bay. Crossfields of
Arnside were the most prolific builders with two yards working. Later branches of the family started yards at
Conway and took over a yard at
Hoylake. Many were constructed by Gibson at
Fleetwood, later taken over by Liver and Wilding. In particular, William Stoba (1855–1931), a foreman shipwright with Fleetwood builders, developed the design and experimented with centreboards. Other builders were working at
Annan,
Millom,
Crossens and
Marshside near
Southport. Over the last 20 years the Nobby Owners Association has restored to sail some 20 nobbies, which are basically Morecambe Bay inshore sail fishing boats, associated with the North West coast of England and which evolved to their present graceful form through the 19th century. ==Manx nobby==
