In time of peace, merchant vessels shall enjoy complete freedom of transit and navigation in the Straits, by day and by night, under any flag any and with any kind of cargo, without any formalities, except as provided in Article 3 below. No taxes or charges other than those authorised by Annex I to the present Convention shall be levied by the Turkish authorities on these vessels when passing in transit without calling at a port in the Straits.
In order to facilitate the collection of these taxes or charges merchant vessels passing through the Straits shall communicate to the officials at the stations referred to in Article 3 their name nationality, tonnage, destination and last port of call (provenance).
Pilotage and towage remain optional.
All ships entering the Straits by the Aegean Sea or by the Black Sea shall stop at a sanitary station near the entrance to the Straits for the purposes of the sanitary control prescribed by Turkish law within the framework of international sanitary regulations. This control, in the case of ship possessing a clean bill of health or presenting a declaration of health testifying that they do not fall within scope of the provisions of the second paragraph of the present Article, shall be carried out by day and by night with all possible speed, and the vessels in question shall not be required to make any other stop during their passage through the Straits.
Vessels which have on board cases of plague, cholera, yellow fever, exanthematic typhus or smallpox, or which have had such cases on board during the seven days, and vessels which have left an infected port within less than five times twenty-four hours shall stop at the sanitary stations indicated in the preceding paragraph in order to embark such sanitary guards as the Turkish authorities may direct. No tax or charge shall be levied in respect of these sanitary guards and they shall be disembarked at a sanitary station on departure from the Straits.
In time of war, Turkey not being belligerent, merchant vessels, under any flag or with any kind of cargo, shall enjoy freedom of transit and navigation in the Straits subject to the provisions of Articles 2 and 3.
Pilotage and towage remain optional.
In time of war, Turkey being belligerent, merchant vessels not belonging to a country at war with Turkey shall enjoy freedom of transit and navigation in the Straits on condition that they do not in any way assist the enemy.
Such vessels shall enter the Straits by day and their transit shall be effected by the route which shall in each case be indicated by the Turkish authorities.
Should Turkey consider herself to be threatened with imminent danger of war, the provisions of Article 2 shall nevertheless continue to be applied except that vessels must enter the Straits by day and that their transit must be effected by the route which shall, in each case, be. indicated by the Turkish authorities.
Pilotage may, in this case, be made obligatory, but no charge shall be levied.

Naval auxiliary vessels specifically designed for the carriage of fuel, liquid or non-liquid, shall not be subject to the provisions of Article 13 regarding notification, nor shall they be counted for the purpose of calculating the tonnage which is subject to limitation under Articles 14 and 18, on condition that they shall pass through the Straits singly. They shall, however, continue to be on the same footing as vessels of war for the purpose of the remaining provisions governing transit.
The auxiliary vessels specified in the preceding paragraph shall only be entitled to benefit by the exceptional status therein contemplated if their armament does not include : for use against floating targets, more than two guns of a maximum calibre of 105 millimeters; for use against aerial targets, more than two guns of a maximum calibre of 75 millimeters.
In time of peace, light surface vessels, minor war vessels and auxiliary vessels, whether belonging to Black Sea or non-Black Sea Powers, and whatever their flag, shall enjoy freedom of transit through the Straits without any taxes or charges whatever, provided that such transit is begun during daylight and subject to the conditions laid down in Article 13 and the Articles following thereafter.
Vessels of war other than those which fall within the categories specified in the preceding paragraph shall only enjoy a right of transit under the special conditions provided by Articles 11 and 12.

The fitting of a landing on or flying off deck on any vessel of war, provided such vessel has not been designed or adapted primarily for the purpose of carrying and operating aircraft at sea, shall not cause any vessel so fitted to be classified in the category of aircraft-carriers.
The wording of the present Annex is taken from the London Naval Treaty of March 25th, 1936.
The category of aircraft-carriers is divided into two sub-categories as follows:
- (a) Vessels fitted with a flight deck, from which aircraft can take off, or on which aircraft can land from the air;
- (b) Vessels not fitted with a flight deck as described in (a) above.
(3) Light Surface Vessels are surface vessels of war other than aircraft-carriers, minor war vessels or auxiliary vessels, the standard displacement of which exceeds 100 tons (102 metric tons) and does not exceed 10,00 tons (10,160 metric tons), and which do not carry a gun with a calibre exceeding 8 in. (203 mm.).
The category of light surface vessels is divided into three sub-categories as follows:
- (a) Vessels which carry a gun with a calibre exceeding 6.1 in. (155 mm.);

- (c) Vessels which do not carry a gun with a calibre exceeding 6.1 in. (155 mm.) and the standard displacement of which does not exceed 3,000 tons (3,048 metric tons).
(4) Submarines are all vessels designed to operate below the surface of the sea.
(5) Minor War Vessels are surface vessels of war, other than auxiliary vessels, the standard displacement of which exceeds 1OO tons (1O2 metric tons) and does not exceed 2,000 tons (2,032 metric tons), provided they have none of the following characteristics:
- (a) Mount a gun with a calibre exceeding 6.1 in. (155 mm.);
- (b) Are designed or fitted to launch torpedoes;
- (c) Are designed for a speed greater than twenty knots.
(6) Auxiliary Vessels are naval surface vessels the standard displacement of which exceeds 100 tons (102 metric tons), which are normally employed on fleet duties or as troop transports, or in some other way than as fighting ships, and which are not specifically built as fighting ships, provided they have none of the following characteristics:
- (a) Mount a gun with a calibre exceeding 6.1 in. (155 mm.);
- (b) Mount more than eight guns with a calibre exceeding 3 in. (76 mm.);
- (c) Are designed or fitted to launch torpedoes;

|(d) Light surface vessels, sub-category (c)||16 years|
|(e) Submarines||13 years|
It is agreed that, of the three over-age training ships, as indicated below, belonging to the Japanese Fleet, two units may be allowed to visit ports in the Straits at the same time.
The aggregate tonnage of these two vessels shall in this case be considered as being equivalent to 15,000 tons.
|Date when laid down||Date of entry into service||Standard displacement (tons)||Armaments|
1. The categories and sub-categories of vessels to be included in the calculation of the total tonnage of the Black Sea Powers provided for in Article 18 of the present Convention are the following:
