Clare Counties making their debut in this competition put up a brave performance against their more illustrious opponents and while Bohes always looked like advancing, they were given a stiff test by the Clare side who were hit by some late defections.
Tries by Ian Condell, Keith McManus and two conversions and a penalty by Darragh Frawley gave the visitors a 17-0 interval lead.
Rory Whyte and Mark Egan scored further tries and Derek Farrell converted these with Frawley also adding a penalty.
Robbie Madden scored the home side's only try, who had good performances from Patrick Harding, Jeff Ruttle and Fergal Lawlor.
