186 Sector 16. Greece—Nisoi Vorioi Sporadhes and Pagasitikos Kolpos16.14 Gaidhouronisia (39˚04'N., 23˚57'E.), consisting of a groupof two low islets fronted by shoals, lies in the SE approach toDhiavlos Alonnisou 6 miles SE of Akra Notos. At times, thesea breaks heavily over this group of dangers.16.14 Nisis Adhelfi, 178m high, lies 2.5 miles NNE of Gaidhouronisia.A chain of islets, rocks, and shoals extends up to 2 milesNNE from the N end of this islet.16.14 Nisis Skantzoura (39˚05'N., 24˚06'E.), located 12.5 milesESE of Akra Notos, is the largest of a group of low islets.Vrakhonisis Korakas, 23m high, lies 2.2 miles SW of the Sextremity of Nisis Skantzoura and is the S and outer islet of thegroup. A shoal, with a least depth of 3m, lies about 0.5 mile SEof this islet and is usually marked by heavy breakers.16.15 Nisis Pelagos (39˚20'N., 24˚05'E.), 300m high, is avery mountainous island. Vrakhos Melissa, a steep-to abovewaterrock, lies about 1 mile E of the S extremity of this island.16.15 Nisis Pelerissa, marked by a light, lies 1.8 miles NW of the Sextremity of the island. This islet lies in the approach to OrmosKira Panayia, a bay which indents the SW side of the islandand provides shelter to small craft with local knowledge. Vesselsentering the bay can pass on either side of Nisis Pelerissa.16.15 Limin Planitis, an inlet, indents the N side of the island andalso provides shelter to small craft with local knowledge.16.15 Dhiavlos Pelagonisou (39˚18'N., 24˚00'E.) leads betweenthe NE extremity of Alonnisos and the S end of Nisos Pelagos.This passage has a least width of 3.2 miles and is deep andclear, except for a group of small islets lying close off AkraGregali, the NE extremity of Alonnisos.16.15 Nisis Yioura (39˚23'N., 24˚10'E.) lies with Akra Yerondi, itsS extremity, located 4 miles E of the N extremity of NisosPelagos. This island is formed by precipitous hills and is almostinaccessible. Nisis Prasson, 158m high, is located 1.2miles SSW of Akra Yerondi. This islet lies at the SE end of achain of small islets and rocks which extends up to 0.9 mileNW from its N end.16.15 Dhiavlos Yiouron (39˚22'N., 24˚07'E.) leads between theNE end of Nisos Pelagos and the SW end of Nisos Yioura. Thisstrait is deep and clear; vessels may pass on either side of NisisPrasson and its surrounding dangers.16.15 In Dhiavlos Yiouron the currents usually set according to thedirection and force of the wind.16.15 Nisos Piperi (39˚21'N., 24˚19'E.), the E island of NisoiVorioi Sporadhes, lies 6.5 miles E of Nisos Yioura. It is 353mhigh and the coasts consist of inaccessible cliffs.16.16 Nisos Psathoura (39˚30'N., 24˚10'E.), the N island ofNisoi Vorioi Sporadhes, is low and fronted by shoals. A mainlight is shown from a prominent structure, 25m high, standingclose SSW of the N extremity of the island. The remains offortifications are situated at the N extremity. Nisis Miga, asmall islet, lies 0.6 mile S of the S end of Nisis Psathoura andis bordered by rocks and shoals. The channel lying betweenthis islet and the S end of Nisos Psathoura is foul and shouldnot be used.16.16 The current during N winds and calms sets strongly towardNisos Psathoura and has been the cause of many disasters. Eastof Nisos Piperi, in October, a slight NE set was observed with afresh breeze from SSW. In November, between positions E ofNisos Piperi and N of Nisos Skiros, no current was observedwith light breezes from the ESE.16.16 Caution.—An IMO-adopted Area to be Avoided, whichmay best be seen on the chart, surrounds the NE part of NisoiVorioi Sporadhes, which has been designated a Marine Sanctuary,and is centered in the vicinity of Nisos Pelagos. This areahas been established in order to avoid the risk of pollution anddamage to the environment. All vessels carrying chemical,toxic, or nuclear substances and tankers over 500 grt carryingoil should avoid this area. The area extends up to 4 miles E ofNisis Piperi, up to 3.5 miles S of Nisis Skantzoura, up to 4miles N of Nisis Psathoura, and up to 9 miles W of the W sideof Nisos Pelagos.Dhiavlos Trikkeri16.17 Dhiavlos Trikkeri (Dhiavlos Trikeri) (39˚05'N.,23˚10'E.) is the approach channel leading into PagasitikosKolpos and Limin Volou. It lies between the N coast of NisosEvvoia and the S side of Khersonisos Trikkeri, a large peninsula,and is deep and clear in mid-channel. The passage is enteredfrom the E between Pondikonisi and Akra Arapis, 5.6miles N. It narrows to a width of 4.5 miles and divides into twoarms at the W end. One arm leads W and NW into DhiavlosVolou and Pagasitikos Kolpos and the other arm leads SW intothe NE end of Dhiavlos Oreon.16.17 Ormos Platanias, entered 1.5 miles W of Akra Arapis, providesshelter, during N winds, to small vessels. Good anchoragecan be obtained in depths of 11 to 18m in the middle of thisbay.16.17 Ormos Khondri Ammos (Andriami) is entered 4 miles WSWof Akra Arapis. The depths within this large bay are generallytoo deep for anchoring. However, small craft can moor, indepths of 5 to 8m, in a cove on the N side of the bay. The conspicuousmountain range on the N side of the passage rises to aheight of 620m about 2.5 miles W of the head of this bay.16.17 Akra Kavoulia (Akra Trikkeri) (39˚06'N., 23˚03'E.) is locatedat the SW end of Khersonisos Trikkeri. A main light isshown from a prominent structure, 9m high, standing on thispoint.16.17 Dhiavlos Volou (39˚06'N., 23˚01'E.) leads from the NW endof Dhiavlos Trikkeri into Pagasitikos Kolpos. This strait isentered between Akra Kavoulia and Akra Stavros, the NWentrance point of Dhiavlos Oreon, 3.5 miles SSE.16.17 Ormos Pteleou (39˚01'N., 22˚59'E.) indents the SW side ofthis strait and is exposed to NE winds and swell. Small vesselscan anchor, in a depth of 18m, off the village of Pigadhi whichstands at the head of an inlet on the N side of the bay.Anchorage can also be taken, in depths of 13 to 24m, off thevillage of Akhillion which stands at the SW end of the bay. Aconspicuous tower stands on the summit of a hill close SW ofPigadhi.Pagasitikos Kolpos16.18 Pagasitikos Kolpos (39˚15'N., 23˚00'E.) is a largegulf which is mostly surrounded by high land. KhersonisosMagnisias, a large promontory, forms the E side of the gulf.Oros Pilion, 1,610m high, stands at the N end of this promontoryand, when seen from the S, shows two peaks some dis-Pub. 132
