How to apply for a mooring permit

This page aims to help you understand the circumstances under which permits are granted; the restrictions in place; and finally, the process and documentation you need in order to apply for a permit. Please read this page and understand it fully before applying for your permit.

The British Indian Ocean Territory (BIOT) is not a tourist destination. You may apply for a permit to moor in the Outer Islands of BIOT only where it is essential for your safe passage across the Indian Ocean, which we must be convinced of before granting you a permit. Access to Diego Garcia is only allowed for those on pre-authorised official duty.

The Outer Islands of the Chagos Archipelago are isolated and uninhabited. They act as an oasis for marine and island species. The BIOT Administration is committed to preserving the rich environmental heritage of the British Indian Ocean Territory. Marine Protected Areas are recognised by scientists and the international community as essential to the conservation and sustainable management of oceans and fisheries. BIOT hosts one of the world’s largest contiguous ‘no take’ marine reserve, along with several strict nature reserves.

BIOT is extremely remote. There are no facilities available to visiting yachts. Yachts need to be completely self-sufficient whilst in BIOT and respect the local environment and restrictions designed to protect it.

RESTRICTIONS

Visits to the islands are tightly controlled and certain restrictions put in place; some of the islands have been designated as Strict Nature Reserves and it is illegal to enter them. If you are granted permission to visit, you must moor your vessel at BIOT approved sites only, to help conserve BIOT’s fragile coral environment. Diving, spear-fishing, removal of flora or fauna and commercial activity (including charter trips and fishing other than for subsistence purposes) are strictly prohibited and any offences will be prosecuted to the fullest extent of the law.

There is no fishing in the entire BIOT Marine Protected Area. The only exception to this is to allow visiting yachts to fish for their own consumption (no more than three days’ worth, without freezing) and only with a hand line. A fishing log must be kept up to date whilst in BIOT waters, as a Fisheries Protection Officer may wish to see it.

STRICT NATURE RESERVES

It is forbidden for any person to approach within 3 nautical miles, land on or anchor at the Strict Nature Reserves. The following islands are strict nature reserves:

Great Chagos Bank:

  1. The Three Brothers and Resurgent Islands (6º09’-4S 71º31’-4E).
  2. Eagle Island (6º12’-0S 71º19’-0E) and Cow Island (6º14’-1S 71º17’-7E).
  3. Danger Island (6º23’-3S 71º14’-4E) and the drying coral reef (6º27’-3S 71º14’-5E).
  4. Nelson’s Island (5º40’-9S 72º19’-0E).

Or to enter the following area within the Peros Banhos Atoll:

All territorial sea, internal water, land and inter-tidal of Peros Banhos (5º20’-5S 71º51’-0E) to the east of a line between the eastern extremities of Moresby Island and Fouquet Island and extended on the same azimuth to the territorial sea limit.

The islands are a conservation area and all flora and fauna, such as fish, turtles, coconut crabs, coral and shells, are protected.

Penalties for infringement of the regulations are severe.

PERMITS

Permits are required in advance of travel. They can take 6 weeks to process, please apply for a permit well in advance of your intended arrival dates.

The permit system is only in place to allow vessels to rest at specific anchorages in order to provide safe passage through the Indian Ocean. In keeping with this, mooring permits will have a maximum validity of 28 days and are valid for the Outer Islands only. You can apply for one, two, three or four weeks.

The charges for a permit are £250 per week from 1 July 2024 (set rate).

Please note, if you are paying from an international (non-UK) bank account, you will need to add £7 to transfers or ensure that all bank charges by the receiving bank are covered by your own account so that we receive the full fee.

To note:

  • Permits cannot be extended once your initial application has been approved (neither before your arrival nor in the Territory) so please think carefully about how much time you will need to stop in BIOT, bearing in mind weather conditions and other factors.
  • Changes will not be considered for those arriving within the window of their permit.
  • Changes to crew members will also not be considered after the permit has been issued.
  • Applications will not be considered from charter vessels, cruise ships, or vessels with fee-paying crews.

  • If you decide not to use your permit, please notify the Administration as soon as possible. Unfortunately we are unable to provide refunds.

  • If you encounter exceptional circumstances (e.g. severe vessel malfunctions, medical emergencies or dangerous weather conditions) and cannot enter BIOT during the period outlined in your permit please contact the BIOT Administration as soon as possible. Any changes to the terms of your permit are solely at the discretion of the Administration.

You should be aware that any person who enters BIOT without permission may be liable to imprisonment for 3 years and/or a fine of £10,000 and the vessel used to enter BIOT waters may be seized and forfeited.

APPLICATION PROCESS

The application process is as follows:

You must read the BIOT Guidance For Yachts (PDF document) document before applying. Please also take a moment to read our information leaflet on invasive species and vessels in transit (PDF document).
