Riviera M400 Sports Cruiser
Listed with RMJ, the Riviera sales office at The Boat Works.
Some boats you appreciate. Others stop you on the marina walk. ONYX is the second kind. Her 2 pac painted black hull gives this 2008 Riviera M400 Sports Cruiser a presence few boats her size can match, and the moment you step aboard it's clear she's been owned by someone who cared about getting the details right.
The upgrades have been chosen with real taste. The cockpit has been refreshed with recently replaced upholstery, making it an inviting space for long lunches at anchor or sunset drinks back at the berth. Inside, new vinyl flooring through the saloon and galley gives a clean, modern feel that's also practical for wet feet and sandy kid. The new carpet in the cabins provide that 'soft under foot' feeling you want when walking into your cabin for the evening.
Just as importantly, the costly jobs are already done. A current suite of modern electronics is installed, and she was freshly antifouled in October 2026.
Power comes from twin Volvo Penta D6 diesels, a well-proven pairing in a hull that has earned the M400 its strong reputation among Australian boaters. Whether it's a run up the Broadwater, or a weekend away in the bay, ONYX is comfortable for both.
Key features:
- New dash and steering wheel
- New fusion remote control for helm
- New internal and external upholstery including sunbed
- New cockpit covers
- New Imported Amtico Marine flooring
- New electrical switches with usb charging to saloon and main cabin
- New TV and hdmi port to aft cabin cupboard for Xbox ect
- New mattresses throughout (never slept on)
- New luxurious solution dyed nylon carpet on New underlay
- New antennas
- Starlink installed
- Antifoul and prop speed Oct 26
She is definitely one of the best-presented M400s I've come across. Photos can only tell a story so far, this is one boat that you need to see to appreciate.
