I think the twin-funnel, tug-like vessel is pumping water out of the part-submerged vessel - the tug might be registered in Sunderland, but I can't make out the name

The cart on the jetty seems to be on a flat skid, which runs on rails along the jetty.

EDIT: The man behind the horse at the landward end of the jetty seems to be leaning on an empty skid - the cross-rail he's leaning on would support the shafts of the cart

The first edition Ordnance Survey 6" map shows lots of collieries along the coast between Fair Head and Ballycastle, so it seems likely that coal brought by cart to the jetty at Ballycastle, where the skids on the jetty allowed coal to be tipped directly into the ships.
The collieries seem to have worked the coastal cliffs and had great names:
Salt Pans Colliery
White Mine Colliery
Falbane Colliery
North Star Colliery
West Mine Colliery
Lagglass Colliery
Goldnamuck Colliery
Pollard Colliery
Griffin Colliery
Gobb Colliery
Portnagree Colliery

The wreck may well be that of the Grimsby steam trawler Starling which sank in the harbour in 1902.
