William Watson, of the City of Dublin Steam Packet Company, held patents for a double canal boat, capable of being shortened to pass through locks, and for a form of composite construction for boats, with iron ribs and wooden planking. I found recently that at least one composite boat was built for the CoDSPCo at the Brunswick boatyard in Ringsend, Dublin.
The invaluable Grace’s Guide had no entry for the Brunswick boatyard/dockyard but, when I mentioned the matter, undertook some research and produced a page about it. Grace’s and I would welcome any more information about that yard; as the Guide says:
The precise location of the dockyard has yet to be identified.
Pat Sweeney’s Liffey Ships and Shipbuilding (Mercier 2010) just mentions Henry Teal [sic]; Irish Maritime History’s list is light on early nineteenth century construction.
I would welcome information about other yards that might have built vessels for the CoDSPCo.
