Vessels up to 5,000 gt not carrying dangerous or noxious cargoes in bulk or in cargo tanks may transit the inner route. 
Vessels up to 20,000 gt may transit the inner route provided that the vessel does not carry any dangerous or noxious cargoes in bulk or in cargo tanks and the master of the vessel has attended a course held by Icelandic authorities and obtained a transit permit. Tankers with a capacity of up to 5,000 gt may navigate the inner route carrying gas cargoes or petroleum products with maximum kinematic viscocity of 11.0 cSt at 40° C, if the master of the vessel has attended a course held by Icelandic authorities and obtained a transit permit. 
The Areas To Be Avoided are applicable to all SOLAS vessels of 500 gt or more. 
The eastern area may be transited by vessels calling at ports located within the Eastern Area To Be Avoided. Vessels of less than 5,000 gt engaged on voyages 
between Icelandic ports and not carrying dangerous or noxious cargoes in bulk or in cargo tanks may transit the area south of latitude 63° 45´·00N.
