Cruises are typically only canceled for severe weather that might result in danger to the passengers. Such weather may include strong winds and high waves, fog, or severe thunderstorms. Otherwise, our cruises run rain or shine, warm or cold. We do our best to keep passengers with already purchased tickets informed via email or phone if we foresee cruise cancellations, however weather and lake conditions can change quickly and forewarning is not always possible. Alpena Shipwreck Tours reserves the right to cancel a cruise for any reason.
