Hello, thanks for activating the correction, and only taking 10 months.  Is that a record?
The building in question is a sailing club, NOT a yacht club.  A yacht club would focus on yachts, which are large vessels owned by pretentious men, generally.  A sailing club is more inclusive, and is more appropriate for a club where lots of children sail in dinghys.  The name of the club IS in fact Monkstown Bay Sailing Club, as in the initial comment 10 months ago.  Any other name or variation of the name would be a misrepresentation.
I look forward to hearing from you in about 10 months' time.  In the meantime,  I hope you have a great Christmas and New Year.
