The Ballahoo class (also known as the Fish class) was a Royal Navy class of eighteen 4-gun schooners built under contract in Bermuda during the Napoleonic War. The class was an attempt by the Admiralty to harness the expertise of Bermudian shipbuilders who were renowned for their fast-sailing craft (particularly the Bermuda sloops).^[1] The Admiralty ordered twelve vessels on 23 June 1804, and a further six on 11 December 1805.
