We no longer have capacity limits for our Private Cruises. Since we are fully outdoors with lots of moving fresh air, you can cruise with up to 35 people. 


However because of the Presidential Executive Order for masking in Federal buildings, parks and land, and regulated transportation you must be masked on the boat.

Cost for a private 2-hour cruise with no more than 17 guests is $595.00. Extra people are $35 / person. Non-walking infants are FREE but count toward the people on board. All other children are regular price.


A $300 deposit is required to hold the date and book the cruise. 

Additional cruise hours beyond the first two hours are available for a flat $350 per hour regardless of how many guests are on-board.

We can customize any of the following Delta Adventures for you and your guests.

For a 2-hour cruise we can take your group in and out the many bays of Discovery Bay. This cruise is very interesting for guests that are not familiar with the Discovery Bay area.


Another great 2-hour cruise is leaving Discovery Bay to head east on Indian Slough and Woodward Slough to Ski Beach, then north under the new Bacon Island bridge and up to the Middle River Bridge. Then due west along Railroad Slough to the Orwood Railroad Bridge where frequently passenger and cargo trains will motor within feet of the Rosemarie. Setting a southern course, we motor down Old River and west on to Indian Slough.  Soon you will see the Discovery Bay Lighthouse again and the entrance to Discovery Bay. If we have any time left, we will glide in and out a few bays of Discovery Bay so you get to see some spectacular deep water access homes. This cruise allows for vast panoramic views from the top deck of the Rosemarie. Longer cruises can take you to other Delta destinations.
