With the Lusitania expedition in the news, Saturday's Irish Times presents a guide to some of Ireland's most interesting diving sites for all levels of experience.
Though Ireland can boast an abundance of shipwreck sites, a number of them are off-limits to anyone but the hardiest expert explorers, while others require a licence from the Department of Hertiage.
But open dives are still plenty, such as the wreck of UC-42 off Roches Point in Cork, which happens to lie in a popular diving range, and the Empire Hertiage, which lies 30km off the coast of Malin Head and is regarded as one of Ireland's best wreck dives.
Among the licenced dives, the HMS Vanguard - which was tragically sunk 19km east of Bray by its sister ship Iron Duke in 1875 - is a top contender, with the summer months providing astounding visibility of the ship's 9in guns.
