The Green Bay Marina has a rental service for power boats, sail boats, kayaks, paddle boards and fishing gear. Advanced reservation/s is required. Please contact the marina for the prices and more information. To use our powerboats, it is required that you attend our RPBA Class or possess a recognizeable boating certification. If you have a sailing certification, the staff at the Green Bay Marina will do a check ride with you.

Green Bay Marina requires that you have a National Association of State Boating Law Administrators (NASBLA) approved Safe Boaters' Education Card to rent powerboat and sailboats from our rental center. This will allow the marina to meet the requirements set by higher authority.

What is NASBLA? NASBLA is a national non-profit organization that works to develop public policy for recreational boating safety and represents the boating safety of all U.S. states and territories. This will also be a prerequisite to sign up for the powerboat and sailing courses.

There are several sites that offer NASBLA approved safe boating courses online. Here is our recommended website. For more information please stop by the Green Bay Marina or call 243-4155.
