Retail Terms & Conditions

Special Covid-19 Condition

During the Covid-19 crisis, guests may transfer their booking to a later date without penalty subject to us receiving reasonable notice.

Non-Refundable Initial Payment

A 25% non-refundable initial payment is required within 72 hours of making your booking to confirm your reservation. Payment may be made by Visa, MasterCard, American Express, bank draft or bank wire.

Final Payment

Your balance due must be received by our office 60 days before departure. We reserve the right to release your reservation without compensation or refund if you do not pay the balance before the deadline.

Cancellation and Refund Policy

Cancellations received in excess of a year before departure are fully refundable less an administrative fee of USD $100 per berth or may be transferred to a new booking without any administrative fee. This option is only available once for each booking and transferred payments may only be applied as a credit to final payments.

Cancellations received within 12 months of departure are non-refundable. We will do our best to rebook the canceled berth(s) and, if we are able to do so and IF the ship sails full, we will refund your canceled booking less an administration fee of $100.00 per berth or space. If we are able to re-book your canceled berth/space, you will have the option to transfer the full amount paid to a future reservation.


Medical evacuation from remote locations such as Socorro and Guadalupe Islands and treatment can be very expensive. We require all guests to either purchase medical diving insurance from us or to have proof of valid insurance from a recognized and reputable insurance carrier such as DAN or DiveAssure.

Please Note: Travel insurance is different than medical dive insurance and provides peace of mind and financial security as it provides coverage for delay, missed departures due to weather, canceled flights, lost bags etc. We highly recommend DiveAssure travel insurance which the guests can purchase from us. We offer a $100.00 onboard credit to any guest that purchases this insurance from us which results in a typical net cost of $125-150.


Each and every guest is required to provide a Waiver, Release and Indemnity (the “Release”) on or before arrival at the ship and their personal and travel information. You can provide a copy of these documents (found on the Nautilus web site or on request) electronically as soon as confirmation of the reservation has been given but, in any event, no later than 60 days prior to departure. The government of Mexico requires that we submit this information before the boarding day. If this is not done, guests may be refused boarding permission.

We urge all of our guests to double check their travel documents including expiry dates and ensure they obtain any required visas to travel to or through the United States and Mexico if required. We will not issue a refund or credit to guests who are either denied entry into Mexico or permission to board.

Special Requests

We want to serve our guests as best as we can by accommodating all reasonable special requests. Please let us know if we can help with any specific dietary requests or other accommodations at least 30 days prior to boarding. The more notice the better we can serve everyone. It is unlikely that we will be able to respond to last minute or “day of” requests.


While Nautilus understands/appreciates guest reaction to post booking charges after a trip has been booked and shall avoid such whenever possible, we have to reserve the right to add a surcharge in respect of volatile fuel price increases and other unforeseen charges over which Nautilus has no control such as the cost of any imposition of any taxes, levies, fees or other unforeseen charges legislated by the Governments of Canada, USA or Mexico.

Force Majeure

While we will always do whatever we can to ensure the absolute best possible experience for the guests, trip itineraries are subject to change or cancellation without notice at the discretion of the Captain taking into consideration the safety of guests, crew and the vessel for reasons such as inclement weather or seas, mechanical breakdown, governmental orders, port authority directions and other factors beyond our reasonable control. No refund or credit will be issued in such instance.

Contract Changes

Prior to any accepted reservation, Nautilus reserves the right to make changes to the above noted terms and conditions without notice.
