Boka Bay is 30 nautical miles south of Dubrovnik, the Montenegro cruising permit for a 40m yacht runs roughly €1,500 in 2026, and the Tivat-Kotor inlet handles yachts to 100m on a superyacht marina that opened in 2009 and now competes with Antibes and Porto Cervo as a southern Adriatic base. Most Croatia-charter brokers pitch Montenegro as a half-day side trip from Cavtat. That undersells the inlet. Boka Bay is a 32-kilometer fjord-system with four meaningful anchorages, the Kotor old town as the on-shore visit, and a cruising permit regime less restrictive than Croatia's. This piece is the operational read for a 2026 charter party considering Montenegro on its own or as a Croatian extension.
Data here is from 2025 charter operational reports, the published 2026 Montenegro Maritime Safety Department tariff [VERIFY against current schedule], the Porto Montenegro public tariff, and conversations with two captains who run the Boka Bay circuit in season. Where 2026 final values are subject to revision we mark inline.
Where Montenegro fits on a charter week
Three structures work for a Montenegro-inclusive charter:
The Dubrovnik-embarked 7-day round-trip that runs north into central Dalmatia (Mljet, Korčula, Hvar) and includes 1 to 2 nights in Boka Bay on the front or back end. This is the standard "Croatia plus Montenegro" pitch.
The Tivat-embarked 7-day round-trip that runs north into Dalmatia (Elaphiti, Mljet, Korčula) and returns to Tivat. Less common, useful for charter parties flying in via Tivat airport rather than Dubrovnik.
The Tivat-embarked Adriatic charter that runs south into Albania (Sarandë, Vlorë, the Karaburun-Sazan reserve) for a 10-day or 14-day route. The Albanian extension is the new development of 2024 to 2026. See the separate piece on the Albania riviera charter for 2026.
The Boka Bay itself is a 32-kilometer fjord that runs Herceg Novi (the entrance) to Kotor (the head). Four anchorages handle the charter traffic.
The cruising permit
The Montenegro cruising permit (vinjeta) is required for any non-Montenegrin-flag yacht in Montenegrin waters. The Montenegro Maritime Safety Department issues the permit through the Harbor Master offices at Zelenika (Herceg Novi area) and Porto Montenegro (Tivat).
The 2026 schedule [VERIFY against current Montenegro Maritime Safety Department tariff]:
Yachts up to 24m: roughly €300 to €600 annual. Yachts 24m to 35m: roughly €700 to €1,200 annual. Yachts 35m to 50m: roughly €1,200 to €1,800 annual. Yachts above 50m: roughly €1,800 to €3,000 annual.
A shorter-term seasonal permit is available at roughly 50 to 70 percent of the annual rate. For a single-week charter the seasonal permit makes more sense than the annual. For a yacht spending the season in the southern Adriatic, the annual permit is the default.
Per-person port tax. Montenegro applies a per-person daily port tax for yacht charter guests at roughly €1 to €2 per person per day in 2026. The amount is small relative to the Croatian sojourn tax stack.
VAT. Montenegro applies VAT on yacht charter at 21 percent if the charter embarks in Montenegro. A charter embarking outside Montenegro and transiting Montenegrin waters does not pay Montenegrin VAT on the charter fee.
The four anchorages
Porto Montenegro (Tivat). The marina in the centre of the bay, on the south shore at Tivat. Capacity for yachts to 250m on the outside positions. Full utilities, fuel quay, customs and immigration on-site, chandlery, provisioning, and a town center that has been built around the marina (restaurants, retail, the Heritage Museum at the Naval Heritage Collection). The standard embarkation and overnight position. Berth rates in August 2026 [VERIFY 2026 Porto Montenegro tariff] for a 50m yacht: roughly €1,500 to €2,500 per night including utilities. Lower than Dubrovnik or Split.
Kotor (head of the bay). The Kotor old town is a UNESCO-listed walled city at the head of the inlet. The new municipal marina at Kotor accepts yachts to 50m on the quay [VERIFY 2026 Kotor port assignment for superyachts]. Larger yachts anchor in the open bay south of the old town and tender in. The Kotor evening with the city lights on the old town walls is the high-value visual of the Montenegro week.
Herceg Novi (entrance to the bay). The historical town at the bay entrance, with the Forte Mare and the old citadel above. The marina at Herceg Novi handles yachts to 30m on the inside positions. Larger yachts use the open anchorage offshore. Herceg Novi works as the entry-day position for a yacht coming in from Dubrovnik or as a final-day position before clearing back to Croatia.
Žanjic and Mirište (open Adriatic, southwest of Herceg Novi). Two small bays on the southwestern tip of the Lustica peninsula, outside Boka Bay proper but visited on the same itinerary. The water clarity is the best in the area and the bays are quieter than the inner Boka positions. Buoy field and free-anchoring on sand. The day-stop for the swim-and-lunch break before re-entering Boka Bay for the evening at Kotor or Tivat.
What a Montenegro-inclusive Dalmatia week looks like
Day 1 (Dubrovnik embarkation): clear out of Croatia at Cavtat. Run 25 nautical miles to Boka Bay, clear into Montenegro at Zelenika. Overnight at Porto Montenegro.
Day 2: morning at Tivat, day-trip by tender to Kotor (15 nautical miles up the inlet from Tivat). Lunch and afternoon at Kotor. Return to Tivat for the evening or overnight at Kotor anchored in the open bay south of the old town.
Day 3: morning swim at Žanjic or Mirište. Run 25 nautical miles back to Cavtat. Clear into Croatia. Overnight at the Elaphiti Islands.
Days 4 to 7: the standard Dalmatia route through Mljet, Korčula, Hvar, with the option to push to Vis.
The 2-day Boka Bay segment delivers the core of Montenegro without compromising the Croatian week. The customs and immigration time is roughly 1 to 2 hours on each crossing for a properly prepared yacht with the crew documents and the guest manifest in order.
Where brokers undersell Boka Bay
Most Croatia-focused brokers pitch Boka Bay as a single overnight at Porto Montenegro plus a tender trip to Kotor. The structure works but it underuses the inlet. Two nights, with one at Tivat and one at Kotor (or one at Tivat and one at Žanjic for the contrast), produces a meaningfully better Montenegro segment.
The reasons brokers under-pitch Boka Bay:
The broker fee structure is built around the Croatian charter. The Montenegro extension is a margin add to an existing Croatian deal. The broker is not incentivized to make Boka Bay the primary destination.
The customs clearance friction. Crossing in and out of Croatia takes 1 to 2 hours. A broker who pitches a tight 7-day week does not want to spend that time on the proposal call.
The lack of a Montenegro pillar in the broker's site. Most Croatian brokerage businesses have a Croatia page and a Montenegro half-page. The Montenegro content is light because the Montenegro business is the smaller line item.
The result: a $400K Croatian charter week that includes Montenegro as a "highlight day" often shortchanges the actual value of the inlet. The Boka Bay deserves a real 2-night segment, not a half-day check-in.
What we would change about the standard
We would push the broker to propose a 2-night Boka Bay segment on any Dubrovnik-embarked Dalmatia week that includes Montenegro. The single-night structure misses Kotor.
We would push the broker to consider a Tivat embarkation for a Croatia-Montenegro charter party flying in via Tivat airport (TIV). The Tivat embarkation eliminates one customs clearance crossing and the resulting week is one day longer in Boka Bay.
We would push the captain to plan the Kotor evening for a Sunday or a Monday. The cruise schedule at Kotor (published by the Kotor Port Authority) lists which days carry the cruise volume. Kotor's old town in the evening after the cruise passengers have left is the right time to walk the walls and have dinner on the square.
What we passed on
We would pass on the Montenegro single-day pitch from a Croatia-focused broker who admits they have not been to Tivat in five years. The proposal will recommend Porto Montenegro because that is what the broker remembers. The current state of the marina, the customs office hours, and the Kotor cruise schedule are operational details that change. The broker who runs the brief should know them.
We would pass on the Boka Bay overnight at the open Kotor anchorage on a forecast that calls for evening katabatic winds off the surrounding mountains. The bay is sheltered from most directions but the night-time katabatic winds can run 25 to 35 knots into the open anchorage. The Tivat marina position is better on those nights.
We would pass on the Albania extension for a 7-day Montenegro week. The Albanian coast is real and the new charter route is developing, but the Sarandë to Vlorë to Karaburun route needs 5 to 7 days of its own. A 7-day Montenegro week should stay in Boka Bay and use the time properly.
The bottom line
Boka Bay is undersold by the standard Croatian-broker pitch and deserves a real 2-night segment, not a side-trip day. The 2026 cruising permit cost is modest, the customs clearance is manageable with the right preparation, and the marina infrastructure at Porto Montenegro is the strongest in the southern Adriatic. For a charter party that has done the Dalmatia week before and wants something different on the southern end, the Tivat-embarked Boka Bay 7-day round-trip with an Albanian or Dalmatian extension is the strongest 2026 proposal. For a charter party doing Croatia for the first time, the Dubrovnik-embarked Croatia-plus-Montenegro week with two nights in Boka Bay is the version that delivers.
FAQ
How much is the 2026 Montenegro cruising permit? The 2026 Montenegro cruising permit (vinjeta) for a non-flagged yacht is scaled by LOA. For a 40m yacht the annual permit runs roughly €1,200 to €1,800. For a 50m yacht roughly €1,800 to €2,500 [VERIFY against current Montenegro Maritime Safety Department tariff]. A shorter-term seasonal permit is also available.
Can a Croatian-embarked charter spend nights in Montenegro? Yes, the standard structure for a Dubrovnik-embarked Dalmatia-plus-Montenegro week includes 2 to 3 nights in Boka Bay. The yacht clears out of Croatia at Cavtat or Dubrovnik and clears into Montenegro at Zelenika or Porto Montenegro.
Is Porto Montenegro the right base for a Montenegro charter? Porto Montenegro at Tivat is the superyacht marina in Boka Bay with capacity for yachts above 100m, full utilities, a fuel quay, and customs and immigration on-site. It is the operational embarkation port for a Montenegro-embarked charter.
How long does the Croatia-Montenegro customs clearance take? For a properly prepared yacht with crew documents and guest manifest in order, 1 to 2 hours on each crossing. The customs offices at Cavtat (Croatian side) and Zelenika or Porto Montenegro (Montenegrin side) operate standard daytime hours and longer in peak summer.
Does Montenegro charge a sojourn tax like Croatia? Montenegro applies a per-person port tax for charter guests at roughly €1 to €2 per person per day [VERIFY 2026 rate]. The amount is much lower than the Croatian sojourn tax stack.
