IF the ship sails full on departure, we will refund the cancelled berths, less an administration fee of USD100 per berth. IF the trip sails full, instead of a refund less USD100 Administration Fee, you may have the option to transfer the full amount to a future reservation.

Medical diving insurance such as DAN or DiveAssure are a mandatory requirement for all of our expeditions. Proof of insurance will be required prior to departure. We also highly recommend the purchase of travel/cancellation insurance.


A guest form requesting personal and travel information will be sent to you electronically and must be submitted 1 month prior to departure. Late submissions may result in government authorities not allowing you to board the ship. We urge all guests to double check their travel documents are in order and to obtain any visas from your local embassy for the relevant country (if required).

Guests who are unable to board a Nautilus vessel because they have been denied entry into the country or lack the proper documentation will not be issued a refund or credit.

Note: for guests on itineraries to/from Mexico or Canada where you must pass through the United States, please ensure the proper documentation / travel visas are also in order for the U.S.

Special Requests

We will gladly help you as best we can with special dietary needs, nitrox and other requests. We require 1-month notice on special requests. Short notice requests cannot be accommodated.


We fully understand and appreciate how upsetting it is to be notified of a retroactive charge after you have already booked and paid for a vacation and avoid them whenever possible. Fuel prices can be extremely volatile. We reserve the right to add a fuel surcharge if the price of diesel goes over a certain price point. Please contact our office for details if needed. We also reserve the right to pass along the cost of any taxes, levies, fees or other unforeseen charges legislated by the Government of Canada, US or Mexico.

Trip Cancellation

Itineraries are subject to weather and may be changed without notice at the discretion of the Captain in consideration of the safety of guests, crew and the vessel. We will always do our very best to facilitate the absolute best possible experience for our guests. No refund or credit will be issued if government authorities require a change to a trip itinerary.
