3.7.16 AREA 16 - RATHLIN EAST TO TORY ISLAND
 
3.7.16.1 The North Irish coast between Rathlin East Lighthouse and Tory Island is relatively clear of hazards to navigation, which have not already been clearly marked by the relevant GLA or local authorities.
   
3.7.16.2 To take the region as a whole, the three principal islands which lie off this coast, Tory, Inishtrahull and Rathlin, are each provided with sufficient aids, both visual and electronic, to guide the deeper draught, North Atlantic traffic, bound in or out of the North Channel, well North of any inshore hazards which lie along the coast.
   
3.7.16.3 As far as the needs of inshore traffic is concerned, the mainland coast can be described as a series of prominent headlands, jutting out into comparatively deep water, with few exceptions, and a number of very deep, navigable inlets, the principal ones being Sheep Haven, Mulroy Bay, Lough Swilly and Lough Foyle.
   
3.7.16.4 Looking at the region from West to East, Tory Sound is deep and navigable, being delineated by night by the sectored local authority light on Bloody Foreland, as well as the major light on Tory Island.
   
3.7.16.5 Horn Head, which follows, is quite clear of off-lying dangers, and the shoals on either side of the entrance to Mulroy Bay are sufficiently inshore as not to constitute a serious danger.
   
3.7.16.6 The isolated Limeburner Rock, with only 2 metres of water over it, is adequately marked by a First Class lighted buoy which also serves as a useful waypoint for offshore traffic.
   
3.7.16.7 Fanad Head and Malin Head are also relatively free of immediate dangers. However, Inishtrahull Sound, which lies close East of Malin Head can be treacherous sea passage for smaller vessels in certain weather and tidal conditions, and the unlighted Garvan Isles which lie on the landward side of the Sound are a danger to be particularly avoided. The powerful light and racon on Inishtrahull are considered adequate for the guidance of vessels transiting the sound of taking the offshore route.
   
3.7.16.8 Inshore navigation between Inishtrahull Sound and Rathlin Island does not pose any particular problems. Any identifiable hazards are minor and so close to the mainland that they do not call for attention beyond that which is already provided.
   
3.7.16.9 Finally, with regard to the Eastern section of the coast, Rathlin Sound is an important passage for shipping, which is well served by the lighthouses at Rathlin West and Rue Point. The tidal streams and overfalls in this area can be of remarkable strength and turbulence and these two aids, at either end of the sound, can greatly assist the safe transit of inshore traffic.
   
3.7.16.10 The changes proposed for this area can be summarised, as follows:
