Rathmines Boat Ramp sits at Styles Point off Overhill Road in Rathmines, a suburb of Lake Macquarie City, and is managed by Lake Macquarie City Council.

The concrete three-lane ramp launches directly into Catalina Bay, offering a sheltered and well-maintained facility suitable for a range of vessel sizes. A pontoon jetty and an adjacent timber jetty provide added convenience for boaters.

Tidal variation on this part of the lake is minimal, keeping water levels stable for launching. The ramp sees quiet traffic on weekdays and moderate use on weekends.

Supporting amenities include car and trailer parking, toilets, picnic tables, BBQ facilities, and sheltered areas. The nearby Rathmines Park adds further green space for visitors. The area is popular for recreational boating, kayaking, and fishing.
