2026 G3 SunCatcher Elite 324 SL Diamond Arch

The SunCatcher Elite 324 SL Diamond Arch combines comfortable seating with a sport-luxury ride.

The new SunCatcher Elite 324 SL Diamond Arch pontoon delivers a great blend of G3’s signature sturdy construction, fleet-footed performance and luxury amenities. With 300 horsepower and the triple tubes, it has performance and added passenger-carrying capacity.

The big powerplant is thrifty, burning 7.2 gph at 3,500 rpm. It’s quiet, too, allowing for normal-volume conversations.

The SunCatcher Elite 324 SL’s undercarriage features triple elliptical foam-filled 23-by-25-inch-diameter logs with performance-lifting stakes and a full-length undershield to reduce drag from water rushing off the tubes. The pontoons are attached to the deck with heavy-duty extrusions through-bolted 16 inches on center. The whole system works together to give a sport-luxury ride.

Topside, a new perimeter fence designed for a sleeker look and graphics updated for 2026 complement the exterior lines and the interior decor. The traditional deck layout at the bow offers two facing lounges that extend aft to midship. There’s storage everywhere—under the bow loungers, inside the pilot’s console, and under the aft lounger. Drain channels under the seat cushions wick water away from the storage compartments. The Diamond Arch model is available with the radar arch or the standard high-speed Bimini.

The elevated pilot’s console features Helm Master EX, a Siren Pro 3 monitoring system, and a JL Audio MM105 Bluetooth sound system (with eight-channel DSP amp, M6 subwoofer, and elevated M6 speakers)—all are standard, as is a Garmin GPSMAP 1243xsv graph. Hydraulic power steering is also standard. Twin captain’s chairs provide plush comfort while under way, or they can swivel around to face aft when the boat is anchored.

A reversible lounger provides multiple seating and relaxing configurations. A standard aft railing with a gate encircles the aft lounger, keeping everyone safely aboard even when riding facing aft. The stern deck is extended for easy boarding, disembarking and watersports activities. A folding Lillipad Revo boarding ladder is standard, as is a watersports tow bar.
