There was a proposal in the 1830s for a ship canal along the coast, outside the railway embankment, from Dublin to the asylum harbour at Kingstown. A preliminary report was provided by William Cubitt after the House of Commons Select Committee on the Dublin and Kingstown Ship Canal had reported in July 1833.
Henry E Flynn was opposed to the idea and, in his A Glance at the Question of a Ship Canal connecting the asylum harbour at Kingstown with the river Anne Liffey at Dublin &c &c &c [George Folds, Dublin 1834], dedicated to Daniel O’Connell, he wrote eloquently of the drawbacks of the proposal, which included this:
Be it remembered, that the whole coast from Ringsend to Merrion is the bathing ground for the less affluent classes of the Citizens; and hundreds get their bread by attending on and bathing the females who frequent it.
And are the patriotic Would-be’s who support a Ship Canal equally reckless of the health, the morality, and the existence of those persons? Would they have no objection to expose their mothers, wives, sisters and daughters to the immediate wanton gaze, the scoffs, the jeers, the immodest jest, the filthy exposure and indecent exhibitions which the most abandoned race of men [ie sailors] could find in their dissolute minds to perpetrate in their view, and within their hearing? And yet, all this must be the consequence of a Ship Canal in the immediate vicinity of the female baths and bathing ground along the line.
Happily, the canal was never built.
