This 21MFB is a premium mid-size luxury pontoon that blends upscale M-Series styling with true performance thanks to the SPS triple-tube package and Mercury 150 Pro XS. It rides higher, handles more like a sport boat, and feels noticeably more solid than a standard twin-tube pontoon—without sacrificing comfort, space, or elegance.
