Ormos Tris Boukes (38°46'N., 24°35'E.) indents the S side of Nisos Skiros and is entered between Akra Marmara, which is marked by a light, and a point, 2.4 miles E. Three channels lead through the entrance of this large bay which is fronted by Nisis Plati, 40m high, and Nisis Sarakina, 131m high. Dhiavlos Marmara, the W channel, is the best and leads between Akra Marmara and the W side of Nisis Plati. Dhiavlos Plati leads between the E side of Nisis Plati and the W side of Nisis Sarakina. Vessels using this channel should keep to the E side as shoals extend from the E and SE side of Nisis Plati. Dhiav los Sarakina leads N of Nisis Sarakina which is marked by a light at its NE end.
