Millstone Marina & RV Resort

Rentals from Millstone Marina & RV Resort include life jackets, safety equipment, fuel, cooler storage, a bimini top, a Bluetooth stereo and on-site parking. Amenities vary by boat and by season, so confirm what comes with the boat you book.

Missouri law permits unsupervised operation of a motorboat or vessel at age 14, but that is not a guaranteed rental age. A person under 14 may operate only under the direct on-board supervision of a parent, guardian or another person age 16 or older, unless the motorboat is moored. For personal watercraft, an operator under 14 must have someone at least 16 aboard.

As of September 29, 2026, Section 306.127 requires a boating safety identification card for vessel operators born after January 1, 1984, and before January 1, 2006, on Missouri lakes. Beginning January 1, 2027, operators born on or after January 1, 2006, must carry one on waters of the state. The rental operator sets its own minimum, so confirm it when booking.

Yes. Operators born after January 1, 1984 and before January 1, 2006 must carry a boater safety card or boating endorsement when operating a motorized boat or sailboat over 12 feet on the lakes of this state; this includes personal watercraft. The requirement has been in force since 2005. Beginning January 1, 2027 it also covers operators born on or after January 1, 2006, and extends from the lakes to the waters of the state.

Operators under 14 need direct onboard supervision by a parent, guardian, or other person 16 or older. Renters may use a once in a lifetime temporary card valid for up to seven days. Exemptions include qualifying Coast Guard licensees, military members and spouses, approved regatta participants, private waters, and recognized NASBLA credentials. The Missouri State Highway Patrol Water Patrol Division administers the program.

From Gravois Mills, launch at Gravois Mills Access and explore Lake of the Ozarks through the Gravois Arm. The upper arm is the immediate local cruising water. Mill Creek Cove and Indian Creek Cove are better choices for quieter water sports on weekdays, although both can attract anchored boats on weekends.

For a longer run, follow the Gravois Arm to the Lake of the Ozarks main channel, where the water is broader and less sheltered; the local boating guide advises against wakeboarding there. New renters should begin on the arm, use the coves when clear and treat the main channel as the open-water option.

From Gravois Mills, Lake of the Ozarks day trips include Coffman Beach Access, Lake Ozark’s Bagnell Dam Strip and Grand Glaize Beach. Coffman Beach Access on the Gravois Arm is a useful fishing stop with docks and a boat ramp; Lake Ozark combines the historic Strip with dining, entertainment and family attractions; and Grand Glaize Beach in Lake of the Ozarks State Park offers sand, swimming, restrooms, changing facilities and nearby picnic areas. Together, they provide options for fishing, time ashore and a beach break.
