The provisions of this Chapter referring to ships, unless otherwise expressly provided, apply to all ships on all voyages. ARTICLE 34. Danger Messages. The master of every ship which meets with dangerous ice, a dan- gerous derelict, a dangerous tropical storm or any other direct danger to navigation is bound to communicate the information, by all the means of communication at his disposal, to the ships in the vicinity, and also to the competent authorities at the first point of the coast with which he can communicate. It is desirable that the said informa- tion be sent in the manner set out in Regulation XLVI. Each Administration will take all steps which it thinks necessary to ensure that when intelligence of any of the dangers specified in the previous paragraph is received, it will be promptly brought to the knowledge of those concerned and communicated to other Adminis- trations interested. The transmission of messages respecting the dangers specified is free of cost to the ships concerned. ARTICLE 35. MeteorologicalServices. The Contracting Governments undertake to encourage the collec- tion of meteorological data by ships at sea, and to arrange for their examination, dissemination and exchange in the manner most suitable for the purpose of aiding navigation. In particular, the Contracting Governments undertake to co-operate in carrying out, as far as practicable, the following meteorological arrangements:- (a) to warn ships of gales, storms and tropical storms, both by the issue of wireless messages and by the display of appropriate signals at coastal points; (b) to issue daily, by radio, weather bulletins suitable for shipping, containing data of existing weather conditions and forecasts; (c) to arrange for certain selected ships to take meteorological observations at specified hours, and to transmit such observations by wireless telegraphy for the benefit of other ships and of the various official meteorological services; and to provide coast stations for the reception of the messages transmitted; (d) to encourage all ship-masters to inform surrounding ships whenever they experience wind force of 10 or above on the Beaufort scale (force 8 or above on the decimal scale).
