The Irish Sea graticule is at latitude 53, longitude -5. It is completely water (except one tiny edge of the Lambay Island), and lies just off the coast of Dublin. Many ferries passes through this graticule, making for a challenging Geohash. This is the only graticule in the Irish Sea that is wholly water, although the Fishguard graticule to the south comes close with over 99% water.
