The short answer is no. Every cruise has a stated boarding and departure time. You can board the boat at any time during the window. For most of our cruises, we offer a full hour to board, while a select few cruise types have 30 minute boarding windows. Please refer to your cruise confirmation for information regarding your specific boarding time. It is our goal that every one of our cruises leave at its scheduled departure time. There are extenuating circumstances that sometime arise and in those cases that are deemed to be outside the control of a large number of our guests, departures will be help for up to 10 minutes. We urge you to arrive early and to leave plenty of time for traffic and parking. The Newport area can get very congested especially on the weekends in the summer. Per our reservation policy, any reservation not transferred to a new date and cruise 48 hours prior to the cruise or any reservation without ticket assurance does not receive a refund.
