PREFACE This sixth edition of the Indian Notices to Mariners, Special Edition contains Special Notices to Mariners 1 to 28 which are of permanent nature. This edition contains the latest information received at the National Hydrographic Office, Dehradun till date. Copies of this publication can be obtained from authorised agents for the sale of Indian charts. The National Hydrographic Office maintains updated navigational charts of the Indian subcontinent and adjacent areas and associated nautical publications. Mariners and concerned authorities are requested to inform this office of any changes affecting these permanent notices. Observations and suggestions can be sent to this office through the official website www.hydrobharat.gov.in or email at [email protected] & [email protected]. Information received and assessed will be included in the Indian Notices to Mariners. This edition supersedes the fifth edition (2012), which is cancelled.

Special Notice No. 2: AVAILABILITY OF NOTICES TO MARINERS 1. Indian Notices to Mariners are published fortnightly on 01st and 16th of every month and can be downloaded from INHD website www.hydrobharat.gov.in 1 Special Notice No. 3 : RELIANCE ON CHARTS AND PREDICTED TIDES 1. Prudent mariners navigate with adequate under-keel clearance at all times, making due allowances for all the factors that are likely to reduce the depth beneath their keels. Mariners shall use a vessel’s deepest draught when calculating the underkeel allowance. Underkeel allowance means the minimum clearance available between the deepest point on the vessel and the bottom, in still waters. Mariners shall apply a plus or minus allowance for the tide. Mariners calculate their vessel's deepest navigational draught and the controlling depth of the intended transit, including consideration of the following:- (a) The vessel's mean draught; (b) The vessel's trim and list characteristics; (c) The intended transit speed and the corresponding squat characteristics; (d) The tide and current conditions; (e) Present sea state conditions; (f) Past weather impact on water depth; (g) The depth at the facility or anchorage; and (h) The depth of the transit area. 2. To ensure an adequate under-keel clearance throughout a passage, an under-keel allowance may be laid down by competent authority or determined onboard when planning the passage. The factors to be taken into account when determining this allowance are given in "The Mariner's Handbook". 3. However, it is becoming increasingly apparent that economic pressures are causing mariners to navigate through certain areas using an inadequate under-keel allowance. Attention is therefore drawn in particular to the limitations of Hydrographic Surveys and tidal predictions in offshore areas. 4. Hydrographic Surveys have inherent technical limitations. Furthermore, in some dynamic areas the physical conditions and hence the depth of the sea-bed is constantly changing. Nautical charts can therefore seldom, be absolutely reliable in their representation of depth and when tidal predictions are applied to charted depths as if they were actual tidal levels the uncertainties are clearly compounded. 5. The limitations of Hydrographic Surveys are discussed at length in "The Mariner’s Handbook" and factors affecting predicted tide levels are described in the introduction to Indian Tide Tables. 6. The frequency and amplitude of negative storm surges, which should also be taken into account, are described in "The Mariner's Handbook". 7. Mariners, therefore, should allow for navigational uncertainties by preserving adequate clearances, both horizontally and vertically. 2 Special Notice No. 3A : RELIANCE ON THE USE OF ENC AND ECDIS SYSTEM 1. The electronic chart and associated systems represents an entirely new approach to
