The site on which St Osyth Boatyard sits has been a port since 1214.

Barges used to trade up to St Osyth, moving farm produce and servicing the tide mill.  Apparently during the depression there were 22 barges laid up there, awaiting work. The South Bank was used for boat building while the north side was used for wharf and cargo.  Several Thames barges and the schooner "Kathleen" were built there. The slipway was first put in in 1945 and was put there to haul out Fairmiles to convert them to houseboats.
