Cruise Info:

Birthday Cruises are typically two-hour cruises. We can accommodate nearly any day and time for your birthday party. You may bring your own snacks, food, cake & decorations on board subject to our standard policies. Take a look at our Food & FAQ's pages for details and restrictions. You can bring your own music or we can provide a mix of party music.

Booking your cruise:

Take a look at our Calendar page to determine if the date you want is available. If there already a booked cruise on the date you want, click on the booked cruise and you the see the time of the booked cruise. If the cruise times you want  allow at least an hour in-between cruises we may be able to accommodate your cruise on that date.


Once you have decided on a date and time, fill in the form to the right and click "Submit". We will get back and if the date and time are OK we will send you a Charter Agreement via e-mail to book and hold the cruise. In the Charter Agreement you will see your cruise deposit amount (typically $299 for a 2-hour cruise) and instructions on how you can pay your deposit on our website with a credit or debit card. Once we receive your signed Charter Agreement and deposit your Birthday cruise will be posted on our Calendar page and you will be all set.

Cruise Drinks:

The Rosemarie has no-host bar and full liquor license and therefore we connot allow drinks to be brought on board without prior written permission. See our Drinks page for full details.
