It’s large swim platform is ideal for boarding and lounging

The first watercraft to hang out on the water with the largest swim platform in the industry. Flat, stable and comfortable, it is ideal for boarding, lounging, and prepping for tow sports. Create even more space by removing the rear seat.

Riders can quickly change from a 3-seat configuration to a flat lounge area when stopped to enjoy the surroundings. Two riders can face each other for a picnic lunch, or when removed, the larger, flatter rear deck makes boarding and prep for tow sports easier and more stable.

At Rest. At Speed. Always Steady.

The wider hull offers industry leading stability

Industry-leading stability and control starts with a lower center of gravity, which gives confidence in rough water, at high speeds, at rest, and with three passengers. The platform is also wider for worry-free boarding and movement around the watercraft. Combine those with a deep-V ST3™ hull that increases performance in rough water and provides better control while cornering, and riders have the best of all worlds in any condition.

What they say?

“The new 2020 Sea-Doo RXT-X is an amazing machine that is definitely worth a look if you are looking for a performance PWC. It arrives with the ST3 platform, which offers the greatest stability in the industry; you can re-board even from the side of the machine!”

“Sea-Doo’s designers paid close attention to creating the most comfortable cockpit possible; the footwells are deep and surprisingly wide, allowing the rider plenty of room to move around the watercraft. The Ergolock seat is smartly sculpted to fit most adult riders, and features angled footwedges to help position the driver’s knees into the padded coves for better handling.”
