2003 Riviera 40 Flybridge

If you're in the market for a mid-size sportfisher, look no further. The Riviera 40 Convertible offers an ideal blend of sportfishing capability and family comfort, making her a standout choice for Southern California boating.

With a practical two-stateroom layout and a head with separate stall shower, the Riviera 40 feels remarkably spacious for her size. She is a perfect fit for the crossover boating lifestyle of the Pacific Coast-equally at home offshore chasing fish or spending a relaxing weekend with family on the mooring or at anchor.

5 Diamonds is well equipped and rigged in sought-after West Coast style. From the cockpit bait systems to the full suite of Garmin touchscreen electronics and interior appointments, this boat is loaded with features that make her both functional and enjoyable to own. She is outfitted with a Bluewater cockpit bait system and thoughtfully arranged fishing features throughout.

Repowered with desirable, low-hour Caterpillar C-7 diesels that have had the 1000 hour service, 5 Diamonds offers excellent responsiveness around the dock with the nimble handling of a smaller boat, while still delivering the comfort, range, and fuel economy expected of a larger convertible.

Beyond her offshore capabilities, this Riviera also shines as a versatile family boat. In Southern California, the ability to comfortably transition from fishing platform to entertaining space is essential, and this boat does it exceptionally well. The cockpit bait tank can easily double as a cocktail or hors d'oeuvres table, creating a casual outdoor dining space, while the salon offers a warm and inviting retreat when the afternoon breeze picks up.

The flybridge layout is exceptional, featuring dual helm seats, a large forward lounge with table, wet bar, and refrigerator-creating a comfortable space for entertaining or relaxing underway. The bridge is covered by a hardtop and fully enclosed with nearly new polycarbonate, providing excellent protection from the elements while maintaining visibility.

Inside, the salon is bright and comfortable. To port is a convertible settee with a pull-out single berth, while to starboard the dinette features a beautifully finished table that adds warmth and style to the living space. An entertainment center above provides the perfect setup for winding down with a movie at the end of the day. New flooring and headliner throughout the vessel give the interior a clean, updated feel.

Just below the salon is the mid-level galley-one of the highlights of the Riviera 40 layout. Often considered the perfect compromise between a galley-up and galley-down design, this arrangement keeps the cook connected to the rest of the boat without sacrificing valuable salon space.

Down the companionway, the guest stateroom is to starboard and features three generous bunks along with a washer/dryer combo, making it an excellent space for kids, guests, or crew. Forward, the master stateroom features an island queen berth, hanging lockers, and drawer storage. To port in the companionway is the head, equipped with a Dometic system and separate stall shower.

For those seeking a highly versatile convertible that checks the boxes for serious fishing, comfortable cruising, and family-friendly accommodations, 5 Diamonds is an exceptional opportunity.
