The Sea-al Supa Skua was first made in the mid to late 1980s. It is a 3.5 metres (11 ft 6 in) aluminium boat with a 22 kilowatts (30 hp) motor on the originals and 18.5 kilowatts (24.8 hp) for the Brooker made boats.. The boats were all coded with a serial number. The 'Skuas' marked between 0-699 are made by the company Sea-al. Sea-al was bought by another Aluminium boat company, Brooker. After the takeover brooker retained Sea-al's design until the early to mid-1990s when they made their own design based on the original, and renamed it the 'Supa Skua'.
