Addu Atoll

Addu is the southernmost Maldivian atoll, crossing the equator around Gan. Its signature dive is the British Loyalty, a merchant oil tanker used as a wartime storage hulk, torpedoed by U-183 in March 1944 and deliberately scuttled in January 1946.

The short version

Known forThe 134m British Loyalty oil-tanker wreck, torpedoed in 1944 and deliberately scuttled in 1946.

Main tradeoffThe British Loyalty reaches about 33m, below the Maldives' 30m recreational limit; the lower hull and deep penetration are outside a normal recreational profile.

Permit or park fee

What you pay

Regulation 2018/R-105 provides access-permit and activity fees for Addu Nature Park protected areas, but a current public scuba rate for Manta Point or British Loyalty was not independently verified. Fees can be changed by the Fund Board

confirm the amount with Addu Nature Park or the operator.

How it works

Manta Point/Kandihera Maa Kandu and British Loyalty are governed by the Addu Nature Park protected-area regulation, which provides access permits and activity fees and requires protected-area diving tours to use approved marine guides. Confirm the currently applied permit and fee with Addu Nature Park or a licensed operator. Maldives recreational diving is capped at 30m.

Research is source-backed, but conditions and fees should still be confirmed locally.

Note on the data: Site coordinates are approximate and should not be used for navigation. Addu-specific manta photo-ID data sufficient to validate a monthly peak was not located, so no month is coded peak and the year-round claim is represented conservatively. The British Loyalty dates conflict in secondary sources; uboat.net records the U-183 strike on 9 March 1944 and scuttling on 15 January 1946, while some local summaries give 5 January. The source also records earlier damage at Diego Suarez. No evidence was found that the empty storage hulk is a protected war grave. Published protected-area material confirms management coverage for Manta Point and the wreck, but a current scuba fee schedule was not found. The 2022 national reef report says Addu was less affected in 2016, not unaffected in 1998. The 2024 heatwave was nationwide; a current Addu-only post-event reef survey was not located. Direct international air schedules to Gan require checking at booking time. Water temperature: Rounded monthly bands are based on historical sea-surface minima and maxima; temperatures at depth can differ and these are not dive-computer measurements. Access: Gan is itself an international airport and most land-based dive bases are roughly 15–40 minutes away by road or short boat transfer. Direct international service is limited and changeable, so many travellers route through Malé and add one domestic flight of roughly 70–95 minutes; that fallback leg is not counted from the nearest international airport.
