There is no accurate record of shipbuilding at Porthdinllaen before 1776 when the Registers of Shipping started, although many small vessels were built there, but in the next century 1776 to 1876, records show that fifty seven ships were built. In the earlier years most of them were small sloops but a brigantine “Maria” was 95 tons, and built in 1786. Schooners and the occasional brigantine replaced sloops as the size of ships increased. The average size being ninety tons, but varying between the little sloop “Lively” 16 tons built in 1790 and the barque “Robert Jones” 287 tons built in 1866. The last vessel built there was the brigantine “Annie Lloyd” 149 tons in 1876, which was lost in the Bahamas in 1907.
