3.7.17 AREA 17 - TORY ISLAND TO LOOP HEAD
 
3.7.17.1 The Tory Island to Loop Head region is one of the most exposed areas in Northwest Europe, as it takes the full brunt of the prevailing winds and North Atlantic storms.
   
3.7.17.2 The geographical features of this coastline vary considerably along its whole length, and the number of AtoN provided from place to place tend to reflect the density of marine hazards to be found in any one locality.
   
3.7.17.3 For instance, the Co. Clare coast from Loophead to Galway Bay being steep-to with high sheer cliffs and few off-lying rocks, is one of the longest stretches of un-lighted coastline in the country.
   
3.7.17.4 Galway Bay is, in general, well served by the natural protection it receives during severe North Atlantic weather from the strategic location of the Aran Islands. The Bay is adequately lighted, and thus ease of access, but offers limited shelter for large vessels, which may be disabled, or under stress of weather. However, the anchorage to the East of Blackhead Lighthouse is tenable in certain weather conditions and is frequently used by vessels awaiting suitable conditions to enter Galway Harbour.
   
3.7.17.5 The physical nature of the coastline changes dramatically between Rossaveal and Eagle Island. The shoaled and rock strewn coasts of Counties Galway and Mayo protrude out into the North Atlantic and present a formidable number of hazards for the inshore mariner. There is, consequently, a larger number of AtoN provided in this area, the two major ones being Slyne Head and Eagle Island.
   
3.7.17.6 This section of the coast is not well endowed with harbours of refuge for larger vessels, Blacksod Bay, with Blackrock and Blacksod Lighthouses in its approaches, being the most suitable one available.
   
3.7.17.7 The coast from Donegal Bay to Tory island, within which the two major fishing ports of Killybegs and Burtonport are located, is characterised by the highest sea cliffs in the country, Slieve League, and a hazardous rock offshore between Dawros Had and Bloody Foreland, on the West coast of Co. Donegal.
   
3.7.17.8 In addition to the various GLA AtoN in this region, which provide for the needs of shipping in general, the relevant local authorities have adequately provided for the requirements of the Ports and Harbours within their jurisdictions.
   
3.7.17.9 The changes proposed for this area can be summarised, as follows:
