From Fflint and Rhyl newspapers:
PRESTATYN. A SMACK AGROUND - On Sunday morning last [1 December 1883], the
smack "Mona", of Bangor (Richard Williams, master), with a cargo of pig iron
from Glasgow to the River Dee, grounded on the West Hoyle (position known as
No. 136 per chart). The Point of Ayr lifeboat (Mr. Ben. Evans, coxswain), was
put out, but it appeared that the crew of the distressed vessel (three in
number) had taken to their boat and landed about 9 a.m. The unfortunate
fellows proceeded to Bangor by the 10.40 train from Prestatyn. The disaster is
attributed to the inability of the master to see the lights, and his
consequent loss of bearings.
The vessel subsequently became a wreck.
