Some folk have been sailing on the Thames in a boat made of cardboard.
Over two hundred years ago, Isaac Weld navigated the lakes of Killarney in a boat made of brown paper:
Whilst engaged in illustrating the scenery of that beautiful locality, Mr Weld derived additional pleasure from the occupation, in introducing a young and amiable wife to scenes so familiar to himself. To facilitate their rambles, and profiting by his Canadian adventures and his skill as a “voyageur“, he constructed with his own hands the model of an Indian canoe. In the absence, however, of birch bark, he had recourse to successive layers of stout brown paper, creating a sort of papier-maché boat, sufficiently roomy for two. In this paper skiff he actually had the hardihood to intrust himself and fair companion in sundry adventurous voyages on the Lakes.
That is from “Mr Foot’s Memoir of the late Isaac Weld, Esq” in The Journal of the Royal Dublin Society Volume I 1856–57 Hodges, Smith & Co, Dublin 1858. Wikipedia offers a shorter account of the life of the remarkable Mr Weld. His Statistical Survey of the County of Roscommon, Royal Dublin Society 1832, is an invaluable source of information about the Shannon and the Royal Canal, but Mr Weld is also notable for his voyage, along with his equally adventurous wife, on the steamer Thames [originally Argyle] from Dublin to London in 1815. There are brief accounts of the journey here and here; the captain, George Dodd, wrote a book An Historical and Explanatory Dissertation on Steam-Engines and Steam-Packets; with the evidence in full given by the most eminent engineers, mechanists, and manufacturers, to the Select Committees of the House of Commons; togerther with the Committees’ reports, distinguishing and defining safe and unsafe steam-engines, and their proper management: comprising particulars of the fatal explosions of boilers at Norwich, Northumberland, Wells-street, and in America: concluding with a narrative, by Isaac Weld Esq, of the interesting voyage of the Thames steam-yacht, from Glasgow, in Scotland, to Dublin and London [published for the author, London 1818] available here, and Isaac Weld’s account is available here. Mrs Weld may have been the first woman to take an extended sea voyage in a steam vessel.
