Newspaper reports:

An amusing story of the misfortunes of a 17-year-old stowaway was told last night by the crew of the coaster Acme, which turned turtle and sank 16 miles off Holyhead on Thursday afternoon. The lad stowed away at Liverpool on an American ship bound for New York, but was discovered soon after the boat cleared the the Mersey, and was put ashore at Wexford. There he decided he would go home, and tramped to Dublin. But he had no money wherewith to pay his fare to England, perforce he stowed away again - this time on the steamer Acme, which was sailing to Garston with a cargo of timber. But the Acme had bad weather in St. George's Channel. Some sixty miles from the Isle of Man, her cargo shifted, and, without a moment's warning, she turned turtle. The presence of the stowaway had not been suspected; but, at the last moment, he scrambled aboard the only boat that got away.
  The Acme left Dublin on Thursday morning [28th June 1928] and should have been at its destination that night, but, off Holyhead, part of the deck cargo was shifted by heavy seas with the result that the ship heeled on its side and sank within twenty minutes.
  ADRIFT IN HEAVY SEA. Luckily the lifeboat fell into the water under the lee of the ship, and the six men who formed the crew, together with the stowaway, were able to jump into it and get clear before the ship went down. The boat drifted north in the heavy sea and by ten o'clock, when it was sighted off the Isle of Man by a Norwegian ship bound for Glasgow, the seven men were almost exhausted. On board the Norwegian ship "the Rimfakse" everything possible was done for them.

Postscript The position of sinking was specified as "16 miles off Holyhead" or as "off South Stack". The route from Dublin to Liverpool would head 83° to pass north of the Skerries off Anglesey. This would make the location of the sinking in deep water (50m). I am not aware of any report of discovery of the wreckage.
