The U.S. Navy-led Joint Maritime Information Center published Update 109 to its regional advisory note with an information cut-off of 291300 UTC on 29 October. The working primary retrieved this run is the numbered PDF posted on the UKMTO product board as jmic_advisory_update_109_29-oct.pdf. The face of the note is titled Update 109 to JMIC Advisory Note, 01 March – 29 October 2026. The information cut-off is printed as ICOD 291300 UTC. The note is printed as JMIC# 001 26. The regional threat level remains SEVERE. The Strait of Hormuz remains SEVERE. The Arabian Gulf remains SUBSTANTIAL. The Gulf of Oman stays MODERATE. The Arabian Sea stays MODERATE. The Gulf of Aden stays SUBSTANTIAL. Bab el-Mandeb / the southern Red Sea stay SUBSTANTIAL. The Somali Coast / Somali Basin stay MODERATE. The Northern Red Sea / Suez Canal stay MODERATE. The Eastern Mediterranean stays LOW. Confirmed vessel incidents since 1 March are now printed as 160, up from 156 on dedicated Update 108. The confirmed-incidents table adds four files since the last report: UKMTO 182-26, 183-26, 184-26 and 185-26.
That is the working primary. Sunday afternoon’s product is a numbered regional instrument, not a Hormuz reopen, not Update 110, and not a rewrite of Friday night’s dedicated Warning 188-26, Saturday morning’s dedicated Warning 189-26, Saturday night’s dedicated Warning 190-26, or Sunday morning’s dedicated MSCIO Alert 161/26. It is also not Update 108. Update 108’s cut-off was 251300 UTC on 25 October, and 182-26 through 185-26 sat after that clock. The useful facts for a DPA and a bridge team are the first JMIC conversion of 182-26 from an unnamed outbound-Hormuz disablement into a named crude-oil tanker, GHANA PROSPERITY, hit about two nautical miles off Musandam, disabled and anchored, crew reported safe; the 160-incident tally; the 29 October congestion print of about 181 hulls at Fujairah / Khor Fakkan and about 500 waiting outside the Strait; the 25–28 October U.S.-facilitated Hormuz count of 120; and the outlook that still treats further Hormuz attacks as highly likely. Do not treat Saturday afternoon’s dedicated IMO 122-count as a substitute for this numbered note, and do not treat Update 108 as still the current public instrument.
What Update 109 actually added
The confirmed tape is the body of Update 109. ICOD 291300 UTC 29 October. JMIC# 001 26. Regional threat SEVERE. Four incidents since Update 108. Total 160 since 1 March. That is the product. Stay with that wording. Do not invent a fifth row for unused 186-26, dedicated 187-26, dedicated 188-26, dedicated 189-26, dedicated 190-26, dedicated 420/26 or Sunday morning’s dedicated 161/26. Those clocks sit after 291300 UTC. They are not on this note. Do not invent a Hormuz downgrade. Do not invent an IMO move off 122. Do not invent a completed Update 110.
On 182-26, Update 109 names the hull. The table prints the date line as 24 October NAVAREA IX 404/26 and 26 October UKMTO 182-26. Vessel: GHANA PROSPERITY. Vessel type: crude oil tanker. Event type: Attack. Location: Strait of Hormuz. The narrative says UKMTO received a report that on 23 October a tanker, corroborated by NAVAREA IX as the GHANA PROSPERITY, was hit by an unknown projectile approximately 2 NM off the coast of Musandam, Oman, while transiting outbound through the Strait of Hormuz; the vessel was disabled and anchored; crew reported as safe. That is the first numbered JMIC print of Ghana Prosperity against 182-26. Dedicated Warning 182-26 remains an unnamed Attack, 0839 UTC 23 October, outbound Hormuz, disabled, crew safe. Saturday afternoon’s dedicated IMO highlighted-incidents board already carried a second Ghana Prosperity row, IMO 9732541, 23 October, Strait of Hormuz, Damaged, no pollution, as wrap on that PDF, not as a UKMTO naming. Update 109 is the regional-note naming. Hold all three instruments. Do not invent a flag on this row. Do not invent a cargo grade beyond crude oil tanker. Do not invent a projectile type, a fire, a pollution line or an attacker. Do not collapse 420/26 RITI or Friday night’s dedicated Lavan Attack onto this Musandam disablement.
On 183-26, Update 109 withholds the name. Vessel: name withheld until further notice. Vessel type: unknown. Event type: Suspicious activity. Location: Arabian Gulf. The narrative says UKMTO received multiple third-party reports that on an unknown date a vessel was observed on fire approximately 63 NM southeast of Al-Faw, Iraq; cause, crew status and damage unknown; authorities investigating. Dedicated 183-26 remains that Al-Faw fire watch. Do not convert the withheld row into a named hull. Do not convert Suspicious activity into Attack because later Hormuz products used that family.
On 184-26, Update 109 types the file as Advisory. Vessel: multiple, unknown. Location: Gulf of Aden. The narrative says UKMTO received multiple reports of suspicious small craft near merchant vessels in the Gulf of Aden; one boat carried two ladders and a hook with nine persons on board; suspected Pirate Action Group activity; authorities investigating; no damage reported. Dedicated Advisory 184-26 and NAVAREA IX 416/26 remain the Aden keep-clear at 12-42N 047-35E through 032359 UTC 3 November. Update 109 does not reprint that coordinate and does not extend the cancel. Do not treat the nine-person boat as Sunday morning’s dedicated AZINI hijack.
On 185-26, Update 109 withholds the name. Vessel: unknown. Event type: Suspicious activity. Location: Strait of Hormuz. The narrative says UKMTO received a report that on 29 October a vessel was observed on fire 9 NM north of Khasab, Oman; crew status unknown; no environmental damage reported. Dedicated 185-26 remains that Khasab fire sighting. Friday morning’s dedicated NAVAREA IX 417/26 MSV Quba wreck at 26-19.95N 056-16.82E is wrap on that water, not a 185-26 PDF naming on this note. Do not promote Quba onto the 185-26 row as a completed JMIC identification.
The Arabian Gulf operational summary is the paragraph that should replace Update 108’s version in the master’s pack. One confirmed disruption was reported in this period (UKMTO 183-26). On 28 October Sharjah authorities temporarily closed all Sharjah City beaches as a precaution against an oil leak from a tanker, following earlier beach closures in Umm Al Quwain (22–23 October) and at Al Hamriyah (23 October); the authorities have not named the vessel. Traffic flows continued, with anchorage congestion high across the region. The 24–48-hour outlook is unchanged in kind: five attacks inside the Gulf since 7 October and the 26 October Al-Faw fire show that attacks remain a strong possibility throughout the Arabian Gulf, including at anchorages and STS areas off Iraq. Vessels stationary for extended periods, or maintaining AIS-on while static, may face elevated targeting risk.
The Strait of Hormuz summary carries one Attack and one disruption in the period (182-26 and 185-26). IRGC attacks, attempted attacks and/or harassment persisted, including UAV overflight, targeted surveillance of merchant shipping and occasional VHF hailing. Commercial traffic through the Strait remained at reduced levels against the 2025 baseline of about 138 vessels a day. Independent tracking still indicated single-digit transits. U.S. NCAGS data indicated U.S.-assisted flows averaging about 30 vessel transits a day. U.S.-facilitated Strait of Hormuz transits for 25–28 October, the past 96 hours, are printed as 120. Do not add the 120, the 30-a-day series and the independent single-digit series into one throughput figure. Mariners are still advised to remain vigilant for attempted mining within and adjacent to the traffic-separation scheme. AIS-on vessels can expect elevated targeting risk and directed hails instructing them to divert toward the northern Iranian-controlled route. A 30-nautical-mile standoff from U.S. units remains advised. JMIC Advisory Note 016-26 of 28 October, already the dedicated blockade document-pack piece on this desk, is reprinted as the clearance-request tool: signed and stamped PDF copies of last-port clearance, bill of lading, registry certificate, agent appointment letter, receipts or contracts and berth booking, listening watch on VHF Channel 16, and readiness to alter course, stop or lie dead in the water when directed. Contact remains [email protected]. The humanitarian-cargo exemption via NAVCENT NCAGS is still the published tool.
What sits off the list, and the traffic that moved
Sunday’s cut-off is 291300 UTC on 29 October. Update 109 does not print unused Warning 186-26 (CSO, 1600 UTC 29 October, unnamed tanker, unknown projectile, outbound Hormuz, Khasab footer). It does not print dedicated 187-26 (2212 UTC 29 October, 25 nautical miles northeast of Khasab, two attached devices). It does not print dedicated 188-26 (1800 UTC 30 October, unnamed vessel, 40 nautical miles south of Lavan Island). It does not print dedicated 189-26 (time-late 28 October outbound Hormuz crude-oil tanker). It does not print dedicated 190-26 (1419 UTC 30 October unnamed fishing-vessel boarding). It does not print dedicated 420/26 RITI. It does not print Sunday morning’s dedicated MSCIO 161/26 AZINI hijack. Those products sit after the cut-off or outside the Middle East maritime-region table. They are not a completed Update 110.
The Gulf of Oman summary says no confirmed attacks were reported in this period. A vessel identified by the IMO as the CAPE DAO (IMO 9219020), attacked earlier (UKMTO 142-26, updated 26 October), was reported sunk approximately 35 NM east of Sohar, Oman (NAVAREA IX 403/26, 24 October; since cancelled). That sentence is wrap on the already-cancelled Cape Dao wreck instrument, not a new sinking. Naval presence remained elevated because of blockade enforcement. The latest official CENTCOM figures cited in Update 109, dated 17 October, are 138 commercial vessels redirected; four vessels disabled as a result of blockade enforcement; two boarded for blockade compliance. No further CENTCOM blockade-enforcement action was announced in this period. On 28 October, Advisory Note 016-26 relayed the USNAVCENT NCAGS notice that the United States is enforcing a blockade of all Iranian ports. Vessels were expected to respond promptly to military queries and maintain AIS-on unless constrained by security threats.
The Arabian Sea paragraph is marked no change. The Gulf of Aden paragraph carries 184-26 and 416/26 as the 28 October small-craft watch and says commercial traffic remained relatively steady. Southern Red Sea and Bab el-Mandeb traffic remains below the 20 July Houthi selective embargo, with a significant reduction on 28 October; Bab el-Mandeb cargo and tanker transits for 22–28 October print a 28 October drop to 4 cargo and 1 tanker against mid-week teens. The last confirmed Houthi attack on a merchant vessel on this note remains 24 August. MT ASANA, the Tanzanian-flag product/chemical tanker hijacked on 17 July about 65 nautical miles southwest of Mukalla, is still the one merchant vessel remaining hijacked. The southwest monsoon subsided on 15 October; skiff operations further offshore, including from dhow or hijacked fishing-vessel mother ships, are printed as more feasible. Sunday morning’s dedicated 161/26 AZINI mothership-potential line is not on this note. Do not back-fit it.
Infrastructure colour is new against Update 108. On 27 October a fire was reported at Ras Tanura export terminal, Saudi Arabia, via satellite heat detection. The cause is unconfirmed; Saudi authorities attributed it to drone debris, while the Houthis claimed a ballistic missile strike. Saudi coalition airstrikes on Mocha and Dhubab were confirmed 28–29 October and hit the port city of Mocha, including a security headquarters and an area near the port. No other attack on ports, terminals, offshore platforms, oil and gas loading facilities or subsea infrastructure was reported in this period. Do not convert the Ras Tanura heat detection into a named seafarer casualty or a closed export berth. Update 109 does not print a berth closure, a draught restriction or a pollution volume.
Port and anchorage congestion is printed as of 29 October. About 181 vessels were at anchor in the vicinity of Fujairah / Khor Fakkan. About 149 were off Dubai / Jebel Ali to Ras Al Khaimah, mainly off Sharjah / Ajman / Umm Al Quwain. About 58 were in the vicinity of Musandam / Sohar. About 22 were off Bandar Abbas / Qeshm. There was no mass departure, new cluster or gap near an attack area. Approximately 500 vessels were waiting outside the Strait of Hormuz on 29 October, against single-digit to low-double-digit AIS-visible transits per day; the backlog is expected to persist. Data limits: internal AIS estimates; AIS-dark vessels excluded. Periodic repositioning remains advisable. Stationary AIS-on hulls may face elevated targeting risk.
GNSS / AIS interference in the Arabian Gulf remained elevated and steady, concentrated in the western Gulf from Kuwait / Khafji via Dammam to Bahrain and along the UAE coast from Dubai to Ras Al Khaimah. Windward recorded 326 jammed vessels of 6,888 transmitting in the Gulf and Gulf of Oman on 27 October. The Strait of Hormuz remained at the established baseline, and the Gulf of Oman was marginal. In the Red Sea and Bab el-Mandeb, no significant GNSS interference was observed at sea; Windward recorded 25 jammed vessels in the Red Sea on 27 October. No new specific UKMTO, MARAD, NAVCENT or NAVAREA IX GNSS/EMI notices were issued 25–29 October. Baseline advisories remain in force. Cross-check with radar and visual navigation.
The annex is the independent traffic colour Update 108 did not yet have for 25–28 October. Independent cargo-vessel transits through the Strait, S&P Maritime / SeaVision, excluding Iranian-port callers, are printed as 3, 3, 1, 1, 3, 2 and 2 for 22 through 28 October. Independent tanker transits for the same week are 1, 1, 0, 1, 2, 0 and 1. Bab el-Mandeb cargo totals for those seven days are 9, 14, 12, 18, 19, 15 and 4. Bab el-Mandeb tanker totals are 5, 6, 12, 11, 20, 5 and 1. Do not add those independent figures to the 120 U.S.-facilitated count. UKMTO’s own transit, latest-incidents and AIS-anomaly boards are printed as annex headings without a new weekly anomaly total on the retrieved PDF.
What this is not
This is not Update 110, and it is not a rewrite of dedicated Update 108. Update 108, ICOD 251300 UTC 25 October, 156 incidents, remains the previous numbered public periodic note. Update 109 replaces it. Masters who still brief the region as Update 108 will have the wrong instrument in the folder. Masters who brief Sunday afternoon as Update 110 will have invented a later cut-off this desk has not retrieved.
This is not a rewrite of 182-26, and it is not a UKMTO PDF naming. Dedicated Warning 182-26 remains an unnamed Attack, 0839 UTC 23 October, outbound Hormuz, disabled, crew safe. Update 109 is the first numbered JMIC print of Ghana Prosperity against that file, with a two-nautical-mile Musandam offset and an anchored-and-disabled line. Saturday afternoon’s dedicated IMO board already named Ghana Prosperity, IMO 9732541, as a second 23 October Strait row. Three instruments. Do not collapse them into one “UKMTO named Ghana Prosperity” sentence. Do not move Ghana Prosperity onto unused 186-26 or onto dedicated 187-26, 188-26 or 189-26.
This is not a rewrite of 184-26 / 416/26, and it is not Sunday morning’s dedicated AZINI hijack. 184-26 remains the dedicated 1030 UTC 28 October Aden Advisory. 416/26 remains the keep-clear at 12-42N 047-35E through 032359 UTC 3 November. MSCIO Alert 161/26 remains Sunday morning’s dedicated Iranian fishing-vessel hijack, AZINI, 09-42N 053-55E then 09-47N 055-45E. Update 109’s last 96-hour list ends at 185-26. AZINI is not on that list. Do not back-fit a Somali-Basin mothership onto a 29 October afternoon cut-off.
This is not a rewrite of 188-26, 189-26, 190-26, 420/26 or unused 186-26. Friday night’s dedicated Warning 188-26 remains an unnamed vessel Attack, 1800 UTC 30 October, 40 nautical miles south of Lavan Island, port-side projectile, fire, crew reported safe. Saturday morning’s dedicated Warning 189-26 remains a time-late unnamed crude-oil-tanker Attack, outbound Hormuz, 28 October, time TBC. Saturday night’s dedicated Warning 190-26 remains an unnamed large-fishing-vessel boarding with a PAG concern, 1419 UTC 30 October, no lat/long on the public PDF. Friday night’s dedicated NAVAREA IX 420/26 remains RITI on fire and anchored at 26-24.07N 056-24.72E. Unused 186-26 remains a CSO Attack, 1600 UTC 29 October, unnamed tanker, outbound Hormuz, Khasab footer. All of those sit after 291300 UTC or off this table. Do not promote Louise 1, RIT1, Panama, 25-crew or Al Mayeda onto this note.
This is not an International Maritime Organization 123-count. Saturday afternoon’s dedicated IMO highlighted-incidents board remains 122 confirmed / 24 seafarer fatalities as at 30 October. JMIC’s 160 and IMO’s 122 are different datasets. Wednesday afternoon’s dedicated JMIC Advisory Note 016-26 remains the blockade visit-and-search document pack; Update 109 reprints the pack, it does not replace it. This is not Thursday’s dedicated Contship Jet or Khoryv Black Sea files, and it is not Saturday’s dedicated NAVWARN 775/26, 776/26 or 777/26.
Operational implications
A numbered JMIC update is a routing and manning problem before it is a count of who was hit. Hormuz is still SEVERE, with deliberate attacks called highly likely, AIS-on targeting risk, directed hails toward the northern Iranian-controlled route, and a specific watch for attempted mining within and adjacent to the traffic-separation scheme. That guidance did not move because four more files cleared the table. The Arabian Gulf column did not move either. It stays SUBSTANTIAL. What moved is the 182-26 Ghana Prosperity naming and anchored-and-disabled line, the incident tally from 156 to 160, the congestion print from Update 108’s 25 October figure of about 194 hulls at Fujairah / Khor Fakkan down to about 181 on 29 October, with about 500 still waiting outside the Strait, the facilitated count from 101 over 22–24 October to 120 over 25–28 October, and the GNSS colour from Windward’s 21 October 293 jammed print to a 27 October 326 jammed / 6,888 transmitting print. Masters who still brief the region as Update 108 will have the wrong instrument in the folder. Masters who brief Sunday afternoon as a Hormuz downgrade will have the wrong scale on the chart.
The 182-26 paragraph is a briefing-discipline problem, not a new casualty. Friday 23 October’s dedicated Attack PDF left the outbound Hormuz tanker unnamed and disabled. Saturday afternoon’s IMO board named Ghana Prosperity as wrap. Update 109 is the first numbered JMIC note that prints GHANA PROSPERITY against 182-26, types the hull as a crude oil tanker, places the hit about two nautical miles off Musandam, and prints disabled and anchored with crew safe. It does not convert the dedicated PDF into a UKMTO naming. It does not convert “disabled and anchored” into a completed class survey or a wreck. A master’s pack that briefs “UKMTO named Ghana Prosperity on 182-26” has over-read a JMIC row. A pack that briefs the hull as still steaming because an earlier PDF said it continued, or as RITI because 420/26 printed a fire-and-anchor, has collapsed three instruments. Hold the PDF, the IMO row, the JMIC naming, and Friday night’s dedicated RITI NAVAREA as separate sheets.
The Fujairah density and the 500-vessel wait are the other operator facts. Update 109 still parks that density against a Strait that printed single-digit independent cargo transits on several days in the annex and one independent tanker transit on 28 October. Vessels stationary for extended periods, or maintaining AIS-on while static, may face elevated targeting risk. Harbour assists, wreck response and disabled-hull tows operating in that density are in the same watch as shuttle tankers. AIS-off is not a detection shield and is not an order on this note. Do not merge Ghana Prosperity’s Musandam anchorage onto the Fujairah line, and do not merge RITI’s Ra’s Tahir anchorage onto it.
CSOs should replace the 25 October Update 108 pack with Update 109 in the master’s folder and in the charterer’s security clause file. The new named line is 182-26, GHANA PROSPERITY, crude oil tanker, unknown projectile about two nautical miles off Musandam, outbound, disabled and anchored, crew safe. The new tally is 160 since 1 March. The new congestion line is about 181 hulls in the vicinity of Fujairah / Khor Fakkan as of 29 October and about 500 waiting outside the Strait. The new facilitated count is 120 U.S.-assisted Hormuz transits over 25–28 October. The new GNSS colour is Windward’s 27 October print of 326 jammed vessels of 6,888 transmitting. The new infrastructure colour is an unconfirmed Ras Tanura heat detection on 27 October and confirmed Mocha / Dhubab strikes on 28–29 October. None of those edits is a flag circular, a class condition, or a completed MARPOL finding. Do not replace Friday’s dedicated 182-26 PDF, Saturday afternoon’s dedicated IMO 122-count, Wednesday’s dedicated 016-26 pack, or Sunday morning’s dedicated 161/26. They are different instruments. Update 109 is the numbered regional threat note that now sits on top of Update 108.
For a master already shaping Musandam, holding off Fujairah or Khor Fakkan, or still needing a blockade clearance, Sunday afternoon is a document-pack and lookout problem before it is a policy problem. 016-26 remains the working visit-and-search list. Update 109 reprints it; it does not shorten it. Channel 16, the UKMTO emergency line, the MSCIO emergency line and the company duty officer still have to be on the night orders. Registering with one mailbox is not a substitute for the other. Update 109 does not order a daylight-only transit, a deviation around 12-42N 047-35E beyond the existing 416/26 keep-clear, or a halt to visit-and-search compliance. It also does not authorise a master to treat every AIS-on tanker in the Strait as Ghana Prosperity after the fact.
Charterers, P&I and war-risk underwriters will now ask whether the ship was in the Voluntary Reporting Area after 291300 UTC 29 October, whether it was near Musandam after the Ghana Prosperity row, whether it held the 016-26 pack, and whether it was following BMP-MS. They will not be answered by Friday night’s 188-26 Lavan Attack, by Saturday morning’s 189-26 time-late Hormuz Attack, by Saturday night’s 190-26 unnamed boarding, or by Sunday morning’s AZINI hijack. Off-hire and deviation conversations that treat Update 109 as a completed Hormuz reopen, or as a naming of unused 186-26, have misread the cut-off.
Keep the dedicated files on their own lines. 182-26 remains the dedicated 23 October unnamed outbound-Hormuz disablement; Ghana Prosperity on this note and on Saturday’s IMO 122-count is wrap on that PDF, not a UKMTO naming. 183-26 remains the Al-Faw fire. 184-26 / 416/26 remains the Gulf of Aden PAG keep-clear through 3 November. 185-26 remains Thursday’s 9-nautical-mile north-of-Khasab fire sighting. 187-26 remains Friday morning’s unnamed outbound-tanker Attack 25 nautical miles northeast of Khasab. 188-26 remains Friday night’s unnamed vessel Attack 40 nautical miles south of Lavan Island. 189-26 remains Saturday morning’s unnamed time-late Hormuz crude-oil-tanker Attack. 190-26 remains Saturday night’s unnamed Suspicious Activity fishing-vessel boarding. 186-26 remains the unused 1600 UTC unknown-projectile Attack. 420/26 remains Friday night’s dedicated RITI fire-and-anchor. 417/26 remains Friday morning’s dedicated MSV Quba wreck. 161/26 remains Sunday morning’s dedicated AZINI hijack. 016-26 remains Wednesday afternoon’s blockade document pack. Saturday’s dedicated 775/26, 776/26 and 777/26 remain the Bulgarian territorial-sea e-mail, the Galata diving box and the Burgas cutter. Sunday morning’s dedicated ARN 162/2026 remains the Romanian two-nautical-mile drifting-object watch through 021000 UTC 2 November. Do not recast 1 November afternoon as a Hormuz reopen, as unused 186-26 finally published, as Update 110, as an IMO 123-count, or as a corridor closure.
What Operators Should Note
- Log Update 109, ICOD 291300 UTC 29 October, not a Hormuz downgrade. JMIC# 001 26. Regional threat SEVERE. Hormuz SEVERE. Arabian Gulf SUBSTANTIAL. Gulf of Oman MODERATE. Arabian Sea MODERATE. Gulf of Aden SUBSTANTIAL. Bab el-Mandeb / southern Red Sea SUBSTANTIAL. Somali Coast / Somali Basin MODERATE. Northern Red Sea / Suez MODERATE. Eastern Mediterranean LOW. 160 incidents since 1 March, four files since Update 108 (182-26, 183-26, 184-26, 185-26). Replace Update 108 in the master’s pack. Do not confuse this numbered note with the IMO highlighted-incidents board’s count of 122 as at 30 October, and do not stretch it to unused 186-26 or to dedicated 187-26, 188-26, 189-26, 190-26, 420/26 or 161/26.
- Type 182-26 as JMIC typed it, and hold Friday’s PDF and Saturday’s IMO row beside it. GHANA PROSPERITY. Crude oil tanker. Unknown projectile about two nautical miles off Musandam, outbound Hormuz, 23 October. Disabled and anchored. Crew reported safe. Dedicated Warning 182-26 remains an unnamed tanker Attack, 0839 UTC. Saturday’s dedicated IMO board remains 122 / 24 as at 30 October, with Ghana Prosperity IMO 9732541 as the newest named Strait row. Do not invent a flag, a cargo grade beyond crude oil tanker, or an attacker. Do not merge RITI / 420/26, Quba / 417/26 or Friday night’s Lavan Attack onto this row.
- Treat the Fujairah density and the 500-vessel wait as live routing, not as a published closure. About 181 vessels were at anchor IVO Fujairah / Khor Fakkan as of 29 October; about 149 Dubai / Jebel Ali to Ras Al Khaimah; about 58 Musandam / Sohar; about 22 Bandar Abbas / Qeshm. About 500 waiting outside the Strait against single-digit to low-double-digit AIS-visible transits. U.S.-facilitated Hormuz transits 25–28 October: 120. Independent Strait cargo series 22–28 October: 3, 3, 1, 1, 3, 2, 2. Independent tanker series: 1, 1, 0, 1, 2, 0, 1. Do not add those series into one throughput figure. Stationary AIS-on hulls may face elevated targeting risk. Periodic repositioning remains advisable.
- Keep the 016-26 pack, the mining watch and the raised GNSS baseline. Update 109 reprints Advisory Note 016-26: last-port clearance, bill of lading, registry, agent letter, receipts or contracts, berth booking, VHF 16, 30-nautical-mile standoff from U.S. units, NAVCENT NCAGS mailbox. AIS-on targeting risk and directed hails toward the northern Iranian-controlled route remain. Attempted mining within and adjacent to the TSS remains on the outlook. Windward’s 27 October print is 326 jammed vessels of 6,888 transmitting in the Gulf and Gulf of Oman. No new UKMTO, MARAD, NAVCENT or NAVAREA IX GNSS/EMI notice was issued 25–29 October. Cross-check with radar and visual navigation.
- Hold the post-cut-off files on their own lines. Unused 186-26 remains the 1600 UTC 29 October CSO unknown-projectile Attack, Khasab footer. 187-26 remains the dedicated 2212 UTC attached-device Attack 25 nautical miles northeast of Khasab. 188-26 remains the dedicated 1800 UTC unnamed vessel Attack 40 nautical miles south of Lavan Island. 189-26 remains the dedicated time-late outbound-Hormuz crude-oil-tanker Attack. 190-26 remains the dedicated 1419 UTC unnamed fishing-vessel boarding. 420/26 remains RITI. 161/26 remains Sunday morning’s dedicated AZINI hijack. 416/26 remains the Aden keep-clear through 032359 UTC 3 November. Do not promote Louise 1, RIT1, Panama, 25-crew or Al Mayeda onto this note.
- Log the infrastructure colour as unconfirmed heat and confirmed Mocha strikes, not as a closed Ras Tanura berth. 27 October Ras Tanura fire via satellite heat detection; cause unconfirmed; Saudi drone-debris attribution versus a Houthi ballistic-missile claim. Saudi coalition airstrikes on Mocha and Dhubab 28–29 October, including a security headquarters and an area near the port. CENTCOM 17 October blockade line is still 138 redirected, four disabled, two boarded. Asana is still hijacked. The last confirmed Houthi merchant attack on this note remains 24 August. Watch Update 110, a UKMTO PDF after 190-26, or an IMO-board move off 122 — not a headline that Sunday afternoon reopened Hormuz or completed unused 186-26.
Regulas Shipping will keep lining Update 109’s 291300 UTC cut-off against dedicated Warning 182-26, Saturday afternoon’s IMO 122-count, and the post-cut-off 186-26 through 190-26 files so operators can treat Sunday afternoon’s Ghana Prosperity naming, the 160-incident tally and the 500-vessel wait as a live routing pack, not as a Hormuz reopen or a completed Update 110.
