Ireland Development Grant : Steam Dredger " Sisyphus." 
This boat, taken over from the builders just at the close of the financial year 1904-05, was working at Fenit Harbour and in the Tralee canal until the 7th September, 1905, to which date she had lifted over 95,000 tons of spoil. 
She was then docked, surveyed, and passed on to Galway, where she lifted, up to 31st March, 1906, some 13,750 tons of mud in the Commercial Dock, 9,370 tons of gravel and large boulders in the natural bed of the sea at the dock entrance, some of the boulders weighing from 15 cwt. 
to 1 ton each. 
Her total dredgings amounted to over 118,500 tons, and she worked most satisfactorily throughout, without any serious breakage or accident to machinery, notwithstanding the severe strain thrown on it by the compact nature of the materials at Galway. 
She has since, after being docked at Limerick, proceeded under a three months' charter to Dingle.
