Working at the water.

Belfast Shipyard building under construction 2010 - click

  The Belfast Shipyard has turned out to be a great success, when it was being built there was talk of creating 35 jobs, but soon almost 100 people will be employed.  The recent agreement with a boat builder from Rhode Island helped the boost.  The Rhode Island outfit builds boats from composit materials, boats like racing yachts.
  The yard is busy now overhauling pleasure and working boats inside the big blue building, shown here:

The Shipyard reportedly can work on up to 30 boats at a time, inside, and weather permitting a larger number outside.  This work is what I would call "fancy stuff", things like new engines, upholstrey or galley and berthing spaces.  Work on the hull and superstructure  of the boats is also done (shown above).
