The first Seiont was built in 1901 by Lytham Engineering Co. Ltd. for the Caernarfon Harbour Trust. She was kept busy as a tug as there were still many sailing vessels to be towed in the Menai Strait. She also performed the duties as buoy tender.
In her time the mud in the harbour was dug out with shovels and spades, by a squad of workers, and loaded into boats, which were towed out into the tideway by the Seiont. She was sold for further service in 1937 and replaced by the Seiont II.
Seiont II was a steam dredger and buoy tender.
The vessel was built, on the river Weaver, by W J Yarwood of Northwich, who have built hundreds of small vessels since 1840.
It was built in yard No. 604, for its customer -
Completed on 11th November of the same year.
Seiont II served the Caernarfon Harbour Trust well for 42 years, working in the Menai Strait between Caernarfon Bar and Penmon (easterly point of Anglesey) and dredging the berths alongside the Slate Quarry in Victoria Dock and at the Oil Wharf.
Taken out of service by the Harbour Trust in 1978, Seiont II was saved from the scrap yard by a local body formed for that purpose -
In 1990 ownership was transferred to the Seiont II Maritime Trust, who then had the responsibility for the ongoing maintenance. Increasingly the costs of maintaining the engine, and particularly the boiler, became too much. In 1999 the vessel was broken up but the engine was saved, with a hope that it might one day be on display in a Caernarfon museum. This was not to be, so the engine was stored outdoors, at Port Dinorwig (Y Felinheli), until 17 April 2002, when it was delivered to Markham Grange Steam Museum, on loan for 4 years.
On 1st January 2005 the engine was back in steam.
