Regulation 34 - Safe navigation and avoidance of dangerous situations
1. Prior to proceeding to sea, the master shall ensure that the intended voyage has been planned using the appropriate nautical charts and nautical publications for the area concerned, taking into account the guidelines and recommendations developed by the Organization.*
2. The voyage plan shall identify a route which:
2.1. takes into account any relevant ships' routeing systems
2.2. ensures sufficient sea room for the safe passage of the ship throughout the voyage
2.3. anticipates all known navigational hazards and adverse weather conditions; and
2.4. takes into account the marine environmental protection measures that apply, and avoids, as far as possible, actions and activities which could cause damage to the environment
*Refer to the Guidelines for Voyage Planning, adopted by the Organization by Resolution A.893(21)
If an electronic chart system is used to assist voyage planning the plan should also be drawn up on the paper charts. Where official (ENC) vector data is available an ECDIS provided with fully compliant ENC data for the vessel’s voyage may be used instead of paper charts. Raster Chart Display Systems (RCDS) using official and up to date Raster charts can be used in conjunction with paper charts to assist voyage planning and route monitoring. Hazards should be marked on the RCDS as well as on the paper chart. Systems that use unofficial chart data should not be used for voyage planning or navigation.
a.) positions obtained by electronic positioning systems must be checked regularly by visual bearings and transits whenever available;
b.) visual fixes should, if possible, be based on at least three position lines;
c.) transit marks, clearing bearings and clearing ranges (radar) can be of great assistance;
d.) it is dangerous to rely solely on the output from a single positioning system; e.) the echo sounder provides a valuable check of depth at the plotted position;
f.) buoys should not be used for position fixing but may be used for guidance when shore marks are difficult to distinguish visually; in these circumstances their positions should first be checked by other means;
g.) the charted positions of offshore installations should be checked against the most recent navigational notices;
h.) the functioning and correct reading of the instruments used should be checked; i.) account must be taken of any system errors and the predicted accuracy of
positions displayed by electronic position fixing systems; and
j.) the frequency at which the position is to be fixed should be determined for each section of the voyage.

SOLAS V 19.2.1.4 em que se estipula:
“1.) Regulation SOLAS V/1.4 allows Administrations to determine to what extent Regulations 15 to 28 apply to smaller vessels and fishing vessels. In the case of Regulation 19.2.1.4 the carriage requirements for charts and publicationsdo not apply to the following:
e.) Pleasure vessels under 150 gt.”. Small craft
2.) All small-craft users should note that Regulation 34 (Safe navigation and avoidance of dangerous situations) is not listed in Regulation 1.4 and therefore applies to ALL SHIPS ON ALL VOYAGES (Regulation 1.1). The definition of ship in this respect includes all small watercraft. Operators of small craft of the categories listed above should therefore have sufficient charts and published information on board to be able to plan the intended voyage and execute it safely. When the type and structure of a small vessel means that it is
impracticable to carry charts and publications, the crew should have sufficient knowledge of the area of intended operation and of all local dangers and regulations so that they can complete the intended voyage in safety.
Some hydrographic surveys date from the Victorian era. Tom Partridge uses satellite imagery as a sanity check for navigation and finds unexpected benefits
Tom uses Navionics on his plotter and a laptop loaded with charts, plotter software and satellite
imagery. Where some surveys are over 100 years old, it’s a useful blend of old and new Credit.
