Crinniu na mBad - The Gathering of the Boats
The name 'hooker' refers to four classes of boats. All are named in Irish.
The Bád Mór (big boats) ranges in length from 10.5 to 13.5 metres (35 to 44 feet).
The smaller Leathbhád (half boat) is about 10 metres (28 feet) in length.
Both the Bád Mór and Leathbhád were decked forward of the mast.
These boats were used to carry turf to be used as fuel across Galway Bay from Connemara and County Mayo to the Aran Islands and the Burren.
The boats often brought limestone, as ballast, on the return journeys.
The Gleoiteog ranges in length from 7 to 9 metres (24 to 28 feet) and has the same sails and rigging as the larger boats.
They were used for fishing and carrying cargo.
Another boat, the Púcán, is similar in size to the Gleoiteog but has a lug mainsail and a foresail. These smaller boats were entirely open.
