Party Boat or other Boat Tours?

Hi all! Some friends and I will be visiting for the first time to celebrate our 30th birthday later in June. We were hoping on doing some kind of half day party boat on a Friday! Does anyone have any recommendations ? As this is a birthday celebration, we’d like it to have a bar. However, open to any suggestions of different tours too! We are a small group so mainly looking for a shared boat vs private. Thanks!
