The importance of the baseline reference system
2. Crucial futures of zone delimitation 1. Baselines: normal and straight 2. Legal bays
1a. THE NORMAL BASELINE SYSTEM Article 5 The normal baseline is the low-water line along the coast as marked on large-scale charts officially recognized by the state The normal baseline is a land line with double curvature
1b. THE STRAIGHT BASELINE SYSTEM Article 7 In localities where the coastline is deeply indented and cut into, or if there is a fringe of islands along the coast in its immediate vicinity, the method of straight baselines joining appropriate points may be employed.. The straight baselines must not depart to any appreciable extent from the general direction of the coast. THE STRAIGHT BASELINE IS A MARINE LINE
Closing lines with straight baselines (Okinawa/Japan)

conclusion: closing legal bays in Greece The surface difference of the internal waters gained by the introduction of legal bay delimitation is ca. 2.800 Km 2. This is very important regarding the size of the country and the fact that it has no internal waters today.
nevertheless.. none of the previous futures can be exercised in case of countries with opposite coastlines with less than 24nm maritime breadth!..unless agreed!
INTERNATIONALLY PROPOSED METHODOLOGIES TO DELIMINATE MARITIME BORDERS BETWEEN TWO COUNTRIES WITH OPPOSITE COASTLINES 1. EQUIDISTANCE (or median line) 2. SIMPLIFIED EQUIDISTANCE 3. HALF EFFECT 4. THALWEG 5. COASTLINE LENGTH COMPARISON 6. GENERAL DIRECTION 7. EQUAL RATIO 8. POPULATION COMPARISON 9. METHODS BASED ON JURIDICAL DECISIONS to produce an equitable solution!
The equidistance method Country B The simplified equidistance Country B Country A Country A The equidistance line is defined as a line every point of which is equidistant from the nearest points on the territorial sea baselines of the two States A simplified equidistance line consists of the smallest practicable number of elements that maintain the general course of the original equidistance line
The half effect method a small forwarding island of a State can push the bordering line towards the opposite State and in case of many of such islands, the result is not equitable for the opposite State. In this case, the influence of these entities is reduced to half and finally the equidistant point is set at the ¼ of the distance. new boundary middle point Country B half effect point island Country A old boundary
4. THE THALWEG METHOD The thalweg method is defined as the line of maximum depth 5. THE COASTLINE LENGTH COMPARISON METHOD The first step is to ascertain relevant points of the coast and then measure or calculate the total length of the coast. The latter is determined using a minimum number of straight baselines and since this problem has an infinite number of solutions, this delimitation should be coordinated closely with the negotiators. Several methods may be used depending on the agreement between the States, such as: 1.The ratio of the coastal lengths can divide the whole area with the same ratio 2.The ratio of the coastal lengths can divide the whole area with any percentage of this ratio agreed by the negotiators.
6. THE GENERAL DIRECTION METHOD To establish the general direction of a coastline, it may be divided into short segments and the azimuths of the lines linking all the consecutive basepoints are averaged to obtain the average direction. The bisector of the azimuth lines of the opposite States constitutes their common maritime border.

CONCLUSIONS q All methodologies delimitate bordering lines quite close to the existing agreement
CONCLUSIONS q All methodologies delimitate bordering lines quite close to the existing agreement q The bordering polylines are much simpler than the existing polyline with the exception of the Thalweg methodology
CONCLUSIONS q All methodologies delimitate bordering lines quite close to the existing agreement q The bordering polylines are much simpler than the existing polyline with the exception of the Thalweg methodology q Three methodologies give a profit area of 115 Km 2 to Greece and three a loss of 85 Km 2 respectively. q The greatest gains for Greece occur in the maritime region between Rhodes and Kastellorizo islands. The reason for this is that the agreed delimitation may be considered as non- equitable for Greece in this region (according to UNCLOS III)
CONCLUSIONS q All methodologies delimitate bordering lines quite close to the existing agreement q The bordering polylines are much simpler than the existing polyline with the exception of the Thalweg methodology q Three methodologies give a profit area of 120 Km 2 to Greece and three a loss of 85 Km 2 respectively. The greatest gains for Greece occur in the maritime region between Rhodes and Kastellorizo islands. The reason for this is that the agreed delimitation can be considered as non-equitable for Greece in this region (according to UNCLOS III) Ø The equidistance methodology is proposed as the most equitable solution for Greece-Turkey maritime re-delimitation with very simple geometry and fair surface differences (compared to agreement)
