What are the navigational notes?

The Magharee Islands, or Seven Hogs, lie four miles due east of Brandon Point. The group of islands lie north of Rough Point the northern end of a sandy peninsula that separates Brandon Bay from Tralee Bay. Narrow and intricate Magharee Sound passes between the islets and the foul ground off Rough Point. The Sound is deep and wide with a least depth of 4.3 metres and is a ⅓ of a mile wide.
In moderate or clear weather with a favourable tide, there is no great difficulty in running through this cut that saves at least an hour's sailing and adds some interesting navigation. But during westerly gales, a heavy breaking sea breaks right across the sound where it meets an opposing current and it should be absolutely avoided. The worst conditions are to be found in a northwest gale or when there is a heavy swell. So it should be noted that this is not a foul weather short cut. In these times it is best to pass two miles north of the Magharees to avoid possible breakers over two shoals located to the north of the group.
The complete course is 9.49 miles from the waypoint 'West Magharee Sound' to '200 metres south of Great Samphire Lighthouse' tending in a east south easterly direction (reciprocal west north westerly).
