Even charts cannot supply all the information needed for safety navigation. For this reason the State Hydrographic Institute in Split publishes various navigational handbooks with all the detailed information that cannot for technical reasons be shown on a chart.
The Adriatic Sea Pilot (Peljar Jadranskog mora), I E coast, II W coast, provides mariners with various details and information about the Adriatic region, i.e. general hydrographic and hydrologic conditions, general navigation directions, especially for navigating in channels and dangerous areas, details of anchorages and sheltered places, various marks, details of water, fuel and provisions and other important information. The pilot book starts with information on legal regulations concerning navigation, instruction on the use of mariner's handbook, charts etc.
The Pilot to the Ionian Sea and Maltese Islands (Peljar Jonskog mora i Malteških otoka) is similar in content.
The List of Lights in the Adriatic Sea, Ionian Sea and Maltese Islands (Popis svjetionika Jadranskog mora, Jonskog mora, Malteških otoka) contains all necessary details concerning lighthouses, lights and other important navigation signals.
The Radio-Navigation Service (Radio-navigacijska služba) contains all necessary details concerning radio-beacons and coastal radio-stations as well as other information which refer to safety at sea. It is similar to foreign handbooks of the same kind. It has nine parts: A Introduction, B Radio-beacons, C Radiogoniometric stations, D Coastal radio-stations, E Radio information for mariners, F Radio health service, G VHF-service, H Exact time (time signals ) and I Weather forecast for mariners. All parts include the Adriatic Sea, the Ionian Sea and the Islands of Malta. Parts F and I include the Mediterranean also and part H the whole world.
Adriatic Distance Handbook (Daljinar Jadranskog mora) gives the distances in nautical miles between the important coastal ports and harbours on the Adriatic coast. The first part gives the distances between main ports and harbours, anchorages, and places of particular navigational interest. The second part gives distances between smaller harbours and coves arranged in zones.
The Catalogue of Navigation Charts and Publications (Katalog pomorskih karata i navigacijskih publikacija) provides mariners with all information on charts and publications issued by the State Hydrographic Institute in Split. It has an index and a map for selecting the charts needed. The entire Adriatic is divided into quadrangles which shows the zones covered by the charts. The number in each quadrangle is the chart number.
Notice to Mariners (Oglas za pomorce) is a monthly publication. It gives various kinds of information concerning safety at sea in the Adriatic and in part in the Ionian Sea. Its main aim is to give up-to-date information on any changes that should be incorporated into handbooks or navigation charts published by the State Hydrographic Institute in Split.
Before setting on a cruise masters of vessels should study the handbooks, Pilot and charts carefully and in particular take care that they are up-to-date.
All maritime charts and handbooks can be ordered from the Organization for Maintaining Waterways PLOVPUT in Split or their branch offices in all larger Croatian harbours.
