A vessel under 200 GT needs 4 nautical crew here, one more than the same vessel would need tied to a harbour under Annexure F-4. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A vessel between 3000 GT and 6000 GT needs 8, with a dedicated watchkeeping officer required on the bridge. If you manage a Type 3 or Type 4 RSV that regularly makes short coastal runs rather than staying inside port limits, Annexure F-6 is the table that decides its Minimum Safe Manning Document (MSMD), not Annexure F-4 and not Annexure F-5.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide continues our<a href=\"https:\/\/www.indosearch.in\/learn\/minimum-safe-manning-requirements\/\"> series on minimum safe manning requirements for Indian flag vessels<\/a>, which maps every annexure in the circular. It builds directly on our<a href=\"https:\/\/www.indosearch.in\/learn\/minimum-safe-manning-for-river-sea-vessels-in-harbour-operations\/\"> Annexure F-4 guide for RSV harbour operations<\/a>, since the two scales share the same GT bands and, for many vessels, the same crew, right up until the vessel actually leaves port.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Annexure F-6 sits in the middle of the RSV operating spectrum. A River-Sea Vessel confined to port limits sails under Annexure F-4. A vessel making only a short daylight hop between two nearby ports sails under Annexure F-5. Once a Type 3 or Type 4 RSV takes on a genuine coastal passage, one that runs longer than a single daylight leg but stays under 48 hours, Annexure F-6 is the scale that governs it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Is_This_Different_From_Annexure_F-4s_Harbour_Operations\"><\/span>How Is This Different From Annexure F-4&#8217;s Harbour Operations?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Harbour operations, as defined in the general notes shared across Annexures F-3 to F-7, mean activity within notified port limits, with occasional operation permitted up to six nautical miles beyond port jurisdiction. Annexure F-6 covers what happens once a voyage goes meaningfully beyond that boundary, a real coastal passage rather than an extension of port work. That distinction is exactly why the two scales carry different crew numbers at the smaller GT tiers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Is_This_Different_From_Annexure_F-5s_Daylight_Voyages\"><\/span>How Is This Different From Annexure F-5&#8217;s Daylight Voyages?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Annexure F-5 covers Types 2, 3, and 4 on daylight voyages between nearby ports, a shorter and more limited category of passage than Annexure F-6&#8217;s coastal voyages. The practical dividing line is duration and continuity: a daylight hop completed within a single day&#8217;s working hours falls under F-5, while a passage that runs into a second day, up to the 48-hour ceiling, moves into F-6. Type 2 RSVs are cleared for the F-5 category but not for F-6.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Does_Annexure_F-6_Exclude_Type_1_and_Type_2_RSVs\"><\/span>Why Does Annexure F-6 Exclude Type 1 and Type 2 RSVs?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Annexure F-6&#8217;s own title restricts it to Types 3 and 4 only. Type 1 RSVs do not appear anywhere in F-6 because Annexure F-3 already gives Type 1 a single scale covering essentially all of its permitted operations, including work well beyond harbour limits, so a separate coastal-voyage table for Type 1 was not needed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Type 2 is a narrower case. It gets its own row in Annexure F-4 for harbour work and in Annexure F-5 for daylight voyages between nearby ports, but Annexure F-6 simply does not list it. DGMA&#8217;s drafting draws the line for coastal voyages under 48 hours at Type 3 and above, which means a Type 2 RSV&#8217;s permitted range of operation stops at a daylight hop, at least as far as the F-series scales in this circular go.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_the_complete_Annexure_F-6_Minimum_Safe_Manning_for_coastal_voyages_under_48_hours\"><\/span>What is the complete Annexure F-6: Minimum Safe Manning for coastal voyages under 48 hours?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1536\" height=\"1024\" data-src=\"https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/F-6-minimum-safe-manning-scale-showing-crew-requirements-for-RSVs-from-under-200-to-6000-GT.png\" alt=\"F-6 minimum safe manning scale showing crew requirements for RSVs from under 200 to 6000 GT\" class=\"wp-image-2597 lazyload\" data-srcset=\"https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/F-6-minimum-safe-manning-scale-showing-crew-requirements-for-RSVs-from-under-200-to-6000-GT.png 1536w, https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/F-6-minimum-safe-manning-scale-showing-crew-requirements-for-RSVs-from-under-200-to-6000-GT-300x200.png 300w, https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/F-6-minimum-safe-manning-scale-showing-crew-requirements-for-RSVs-from-under-200-to-6000-GT-1024x683.png 1024w, https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/F-6-minimum-safe-manning-scale-showing-crew-requirements-for-RSVs-from-under-200-to-6000-GT-768x512.png 768w\" data-sizes=\"(max-width: 1536px) 100vw, 1536px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1536px; --smush-placeholder-aspect-ratio: 1536\/1024;\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Annexure F-6 runs across five codes, F6-a through F6-e, spanning under 200 GT up to 6000 GT.

That second OS rating is the detail that separates F6-a from Annexure F-4&#8217;s smallest tier, which needs only 1. A short coastal passage, even under 200 GT, keeps a second rating on watch that harbour-confined work does not require.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Changes_at_200_to_500_GT_Code_F6-b\"><\/span>What Changes at 200 to 500 GT (Code F6-b)?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Crew rises to 5 at this tier, with a numbered AB rating and a Cook joining the list for the first time, both positions that stay marked &#8220;not required&#8221; at the equivalent Annexure F-4 tier. The Master&#8217;s qualification also steps up, needing either a Master (NCV) certificate or an NWKO (NCV) holder with 2 years of experience, a longer experience bar than Code F6-a&#8217;s 1-year threshold.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Holds_Steady_From_500_GT_to_3000_GT_Codes_F6-c_and_F6-d\"><\/span>What Holds Steady From 500 GT to 3000 GT (Codes F6-c and F6-d)?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Crew size settles at 6 across both codes and does not move between them. What changes instead is certificate seniority at the Chief Officer position: Code F6-c accepts an NWKO-NCV holder or a 1st Class IV Master, while Code F6-d specifically calls for an NWKO NCV holder with 1 year of experience behind the same base certificate. The Master&#8217;s certificate path also tightens slightly, moving from a 6-month experience floor at F6-c to a full 1-year floor at F6-d.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Applies_From_3000_GT_to_6000_GT_Code_F6-e\"><\/span>What Applies From 3000 GT to 6000 GT (Code F6-e)?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Code F6-e adds 2 more crew, taking the total to 8, and this is the first Annexure F-6 tier where an OINW-equivalent position becomes a numbered requirement rather than being marked &#8220;not required.&#8221; An NWKO (NCV) officer joins specifically to cover navigational watchkeeping on a passage long enough, and far enough from port, to need it as a dedicated role.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_General_Note_5_Affects_Code_F6-e\"><\/span>How General Note 5 Affects Code F6-e<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The circular&#8217;s general notes for River-Sea Vessels add a further condition here. For an RSV of 3000 GT and above, one additional watchkeeping officer, certificated to 1st Class I\/V Master or above, is required whenever a voyage runs beyond 72 hours. Since Annexure F-6 already caps its own voyages at 48 hours, this note mainly matters for planning purposes: a vessel crewed to Code F6-e&#8217;s base of 8 cannot simply extend a coastal passage past the 72-hour mark without adding that extra officer, and doing so would in any case push the voyage outside what Annexure F-6 itself is meant to cover.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Certificate_of_Competency_Rules_Apply_Under_Annexure_F-6\"><\/span>What Certificate of Competency Rules Apply Under Annexure F-6?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Annexure F-6 carries a single certificate rule, and it is stricter than the equivalent rule in Annexure F-4. At least one officer on board must hold a valid Indian GMDSS Certificate of Competency, and this applies across every code from F6-a to F6-e, with no lighter Restricted Operator alternative at any tonnage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Doesnt_Annexure_F-6_Offer_a_Restricted_Operator_Certificate_Option\"><\/span>Why Doesn&#8217;t Annexure F-6 Offer a Restricted Operator Certificate Option?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Compare this with Annexure F-4, which accepts a Restricted Operators certificate for vessels below 500 GT. Annexure F-6 drops that concession entirely, even for a vessel under 200 GT on Code F6-a. The reasoning tracks the nature of the work. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A vessel confined to harbour limits stays close to shore-based communication and rescue support throughout, while a vessel on a genuine coastal passage, even a short one under 48 hours, is exposed to open water conditions where full GMDSS distress and safety communication matters from the first mile out. This is one of the clearest markers that Annexure F-6 treats &#8220;coastal voyage&#8221; as a materially different risk category from &#8220;harbour operations,&#8221; not just a longer version of the same thing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Does_Annexure_F-6_Compare_With_Annexure_F-4_for_the_Same_RSV_Types\"><\/span>How Does Annexure F-6 Compare With Annexure F-4 for the Same RSV Types?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"683\" data-src=\"https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/Comparison-of-F-4-harbour-and-F-6-coastal-voyage-manning-requirements-for-River-Sea-Vessels-1024x683.png\" alt=\"Comparison of F-4 harbour and F-6 coastal voyage manning requirements for River-Sea Vessels\" class=\"wp-image-2598 lazyload\" data-srcset=\"https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/Comparison-of-F-4-harbour-and-F-6-coastal-voyage-manning-requirements-for-River-Sea-Vessels-1024x683.png 1024w, https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/Comparison-of-F-4-harbour-and-F-6-coastal-voyage-manning-requirements-for-River-Sea-Vessels-300x200.png 300w, https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/Comparison-of-F-4-harbour-and-F-6-coastal-voyage-manning-requirements-for-River-Sea-Vessels-768x512.png 768w, https:\/\/www.indosearch.in\/learn\/wp-content\/uploads\/2026\/08\/Comparison-of-F-4-harbour-and-F-6-coastal-voyage-manning-requirements-for-River-Sea-Vessels.png 1536w\" data-sizes=\"(max-width: 1024px) 100vw, 1024px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/683;\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Type 3 and Type 4 RSVs are the only vessels that need to check both tables, since they are the two types common to Annexure F-4 and Annexure F-6. The comparison below uses the confirmed crew totals from both annexures.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>GT Band<\/strong><\/td><td><strong>F-4 Total Crew (Harbour)<\/strong><\/td><td><strong>F-6 Total Crew (Coastal, Under 48h)<\/strong><\/td><td><strong>F-4 Certificate Rule<\/strong><\/td><td><strong>F-6 Certificate Rule<\/strong><\/td><\/tr><tr><td>Under 200<\/td><td>3<\/td><td>4<\/td><td>Restricted Operator accepted<\/td><td>Indian GMDSS CoC required<\/td><\/tr><tr><td>200 to under 500<\/td><td>3<\/td><td>5<\/td><td>Restricted Operator accepted<\/td><td>Indian GMDSS CoC required<\/td><\/tr><tr><td>500 to under 1600<\/td><td>6<\/td><td>6<\/td><td>Indian GMDSS CoC from 500 GT<\/td><td>Indian GMDSS CoC required<\/td><\/tr><tr><td>1600 to under 3000<\/td><td>6<\/td><td>6<\/td><td>Indian GMDSS CoC from 500 GT<\/td><td>Indian GMDSS CoC required<\/td><\/tr><tr><td>3000 to under 6000<\/td><td>8<\/td><td>8<\/td><td>Indian GMDSS CoC from 500 GT<\/td><td>Indian GMDSS CoC required<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Two things stand out. Below 500 GT, moving a vessel from harbour work to a coastal voyage adds crew, 1 extra hand at the smallest tier and 2 extra at the next one, on top of a stricter certificate rule. From 500 GT upward, the two annexures converge on identical headcount, and the practical difference narrows to certificate seniority at specific ranks rather than crew number, as the earlier breakdown of Codes F6-c and F6-d shows. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a shipowner running the same Type 3 or Type 4 hull between harbour duty and short coastal runs, this means the crew list itself does not need to change once the vessel passes 500 GT, but the paperwork confirming which certificates are on board does.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Happens_if_a_Type_2_RSV_Needs_a_Longer_Coastal_Voyage\"><\/span>What Happens if a Type 2 RSV Needs a Longer Coastal Voyage?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is a genuine gap worth flagging rather than glossing over. Type 2 RSVs are covered by<a href=\"https:\/\/www.indosearch.in\/learn\/minimum-safe-manning-for-river-sea-vessels-in-harbour-operations\/\"> Annexure F-4 for harbour work<\/a> and by Annexure F-5 for daylight voyages between nearby ports, but Annexure F-6 does not list Type 2 at all, and neither does Annexure F-7, which is reserved for Type 4 on unrestricted operation. If a Type 2 RSV&#8217;s trading pattern calls for something longer than a daylight hop but the vessel does not hold a Type 3 or Type 4 classification, the F-series scales in this circular do not appear to offer a matching table.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, that gap needs to be resolved before the voyage is planned, not during it. The vessel&#8217;s vessel type classification itself sits on its certificate, issued under the separate RSV Notification that governs construction and freeboard standards rather than manning, so confirming options directly with the concerned<a href=\"https:\/\/mmd.gov.in\/\" target=\"_blank\" rel=\"noopener\"> Mercantile Marine Department<\/a> is the safer route rather than assuming a nearby annexure applies by default.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Special_Conditions_Apply_to_RSV_Tankers_Cargo_Vessels_and_Dredgers\"><\/span>What Special Conditions Apply to RSV Tankers, Cargo Vessels and Dredgers?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The general notes that apply across Annexures F-3 to F-7 carry three conditions specific to cargo type, and Annexure F-6 is no exception.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Are_the_Gross_Tonnage_Ceilings_for_Each_RSV_Category\"><\/span>What Are the Gross Tonnage Ceilings for Each RSV Category?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The GT limit for an RSV tanker is 3000 MT. The GT limit for an RSV cargo vessel is 6000 MT, and for an RSV dredger it runs up to 10,000 MT. This is why Code F6-e stops at 6000 GT for most vessels, since that is the ceiling for RSV cargo classification, while an RSV tanker never reaches F6-e at all, given 3000 GT is already its cap under the RSV category. A dredger working a coastal run above 6000 GT sits outside what this table spells out row by row, so it is worth confirming manning directly with your MMD before that job is scheduled.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"When_Is_an_Additional_Watchkeeping_Officer_Required_Beyond_72_Hours\"><\/span>When Is an Additional Watchkeeping Officer Required Beyond 72 Hours?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">As covered above under Code F6-e, any RSV of 3000 GT and above needs one additional 1st Class I\/V Master when a voyage runs longer than 72 hours. Since Annexure F-6 itself is capped at voyages under 48 hours, this note is really a boundary marker: once a passage is planned to run past 72 hours, it has moved well outside Annexure F-6&#8217;s own scope and needs to be reassessed against a different scale entirely.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Can_Dredge_Grade_Certificates_Replace_Standard_RSV_Certificates\"><\/span>Can Dredge Grade Certificates Replace Standard RSV Certificates?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. On dredgers, the Master, Mate, and NWKO-NCV certificates otherwise required across F6-a to F6-e may be substituted with Dredge Master Grade I, Dredge Master Grade II, and Dredge Mate Grade I respectively, matching certification to the dredging role rather than forcing a conventional deck watch certificate onto a specialist operation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Do_Fair_Weather_Restrictions_Apply_Under_Annexure_F-6\"><\/span>Do Fair Weather Restrictions Apply Under Annexure F-6?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, at the smallest tier. For vessels under 200 GT, meaning Code F6-a, the prescribed minimum manning applies only to operation against fair-weather forecast and conditions, unless DGMA specifically authorises otherwise. This restriction recurs across nearly every annexure in the circular at the 200 GT threshold, and Annexure F-6 is no exception. A small RSV crewed to the bare F6-a minimum, 4 nautical crew, has less redundancy if weather turns during a coastal passage than it would sitting inside a harbour, which is exactly why this concession disappears once a vessel exceeds 200 GT.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Do_Shipowners_Get_an_Annexure_F-6_Manning_Scale_Approved\"><\/span>How Do Shipowners Get an Annexure F-6 Manning Scale Approved?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The process runs the same way it does for every other annexure in the circular. The shipowner or manager submits a safe manning proposal, together with the prescribed self-assessment checklist, to the concerned Mercantile Marine Department. The MMD checks that proposal against the Annexure F-6 minimum for the vessel&#8217;s confirmed RSV type and Gross Tonnage, and against any additional manning the company proposes for trading needs, maintenance, or rest-hour compliance, before issuing the approved MSMD. Our<a href=\"https:\/\/www.indosearch.in\/learn\/minimum-safe-manning-requirements\/#how-do-shipowners-get-a-safe-manning-proposal-approved\"> pillar guide&#8217;s approval and dispensation section<\/a> covers that full process, including how a temporary dispensation is handled if a crew member falls sick or becomes unavailable at short notice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once approved, the vessel must sail strictly to the crew numbers on that MSMD, and<a href=\"https:\/\/www.indosearch.in\/rpsl\/\"> registered RPSL manning agencies<\/a> build their placement and joining plans directly around it. A company that does not yet hold Recruitment and Placement Service Licence (RPSL) status needs that licence before it can place crew against an approved MSMD at all.<a href=\"https:\/\/www.legalbabu.com\/rpsl-license\/\" target=\"_blank\" rel=\"noopener\"> RPSL licence service<\/a> walks through that registration process for companies setting up or renewing an RPSL licence. Every officer standing watch under Annexure F-6, at any Gross Tonnage, also needs a valid GMDSS qualification given the annexure&#8217;s single, non-negotiable certificate rule, and our<a href=\"https:\/\/www.indosearch.in\/mti\/courses\/general-operators-certificate-gmdss\/\"> directory of GMDSS training courses<\/a> lists where that certificate can be obtained.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"FAQs\"><\/span>FAQs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-question-1786772796844\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><span class=\"ez-toc-section\" id=\"What_is_Annexure_F-6_of_DGMA_Circular_No_54_of_2025\"><\/span><strong>What is Annexure F-6 of DGMA Circular No. 54 of 2025?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Annexure F-6 is the minimum safe manning scale for River-Sea Vessels of Type 3 or Type 4 engaged in coastal voyages of duration under 48 hours.

Below 500 GT, F-6 needs more crew than F-4 for the same tonnage, and F-6 requires an Indian GMDSS CoC at every tier, while F-4 accepts a Restricted Operators certificate below 500 GT.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1786772863204\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><span class=\"ez-toc-section\" id=\"How_many_crew_does_a_vessel_need_under_Code_F6-a\"><\/span><strong>How many crew does a vessel need under Code F6-a?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Code F6-a, for RSVs under 200 GT, needs 4 nautical crew: 1 Master, 1 Chief Officer, and 2 ratings covering the OS position with Basic STCW safety training.

A Type 2 RSV is limited to Annexure F-4 for harbour work and Annexure F-5 for daylight voyages between nearby ports, and does not have a matching table for a longer coastal voyage under this circular.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1786772916219\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><span class=\"ez-toc-section\" id=\"Does_Annexure_F-6_apply_to_RSV_tankers_above_3000_GT\"><\/span><strong>Does Annexure F-6 apply to RSV tankers above 3000 GT?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>No. The GT limit for an RSV tanker is 3000 MT under the circular&#8217;s general notes for River-Sea Vessels, so a tanker never reaches the F6-e tier. A vessel operating above that ceiling would need to be reassessed outside the RSV tanker category entirely.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1786772926018\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><span class=\"ez-toc-section\" id=\"Can_a_dredger_use_dredge_grade_certificates_instead_of_standard_RSV_certificates_under_F-6\"><\/span><strong>Can a dredger use dredge grade certificates instead of standard RSV certificates under F-6?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes.

The circular&#8217;s general note requiring an additional watchkeeping officer for RSVs of 3000 GT and above only applies once a voyage exceeds 72 hours, a threshold that already sits well outside what Annexure F-6 is meant to cover.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1786772960839\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><span class=\"ez-toc-section\" id=\"Who_approves_the_Minimum_Safe_Manning_Document_for_an_RSV_under_Annexure_F-6\"><\/span><strong>Who approves the Minimum Safe Manning Document for an RSV under Annexure F-6?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The concerned Mercantile Marine Department reviews the shipowner&#8217;s manning proposal against the Annexure F-6 minimum for the vessel&#8217;s confirmed RSV type and Gross Tonnage, then issues the MSMD.
