2026 DCB M31

The Everyday Exotic.
When performance and luxury collide, the result is the DCB M31 Widebody—a stunning, mid-size exotic supercat that delivers the perfect balance of aggressive speed and everyday drivability. Sharing the same elite DNA as its larger M-Series siblings, the M31 delivers exhilarating performance, precise handling, and the unmistakable refinement that defines every DCB.

Raw Power
Under the hatch, the M31 is powered by your choice of Mercury Racing 565, 600, 700 or the ultimate 1100 twin-engine stern drive packages—each delivering breathtaking performance, torque-rich acceleration, and proven reliability at the highest levels. Whether carving glass or running across open water, the M31 responds with sports car-like precision and high-speed confidence.

Expertly
Built on a widebody platform for enhanced stability and space, the M31 offers seating for six and a cockpit experience designed around both adrenaline and comfort. With its aggressive lines, sculpted wraparound windshield, and handcrafted interior, every detail of the M31 reflects the flawless design and build quality that sets DCB apart.

Deck
The M31 delivers versatility with three deck configurations to match your boating style. Choose the sleek Traditional Full Deck, the Walkthrough Open Bow for easy movement and added seating, or the Full-Windshield Open Bow for wind protection with open-air comfort. The open bow options create a more family-friendly layout with forward seating and easier boarding—perfect for kids and guests. With seating for six and DCB’s full range of custom upholstery, gelcoat, and electronics, the M31 combines big-boat comfort with agile performance.

DCB Signature Lamination Technologies
DCB PerformaLam
PerformaLam features our exclusive Vacuum Infused Resin (VIR) technology combined with a high-performance blend of bi-axial E-glass, Kevlar, high-density balsa, and other proprietary materials. This process ensures consistent resin saturation and complete air removal, resulting in a strong, rigid, and precisely engineered hull.

Slightly heavier than AeroLam, PerformaLam delivers exceptional structural integrity, impact resistance, and overall value. It is a purpose-built solution designed for dependable, high-speed performance with confidence and control.

Every PerformaLam hull is a testament to DCB’s commitment to advanced engineering and meticulous craftsmanship, purposefully built for those who demand performance without compromise.

Precision
At DCB, every boat is a masterclass in engineering excellence. Our proprietary Vacuum Infused Resin (VIR) process ensures perfect material saturation for unmatched strength, rigidity, and weight savings—far beyond conventional vacuum bagging. Backed by composites engineers and crafted by the industry’s finest, each DCB hull combines advanced materials into a structure that redefines performance. This is construction at its highest level—where innovation meets obsession.

Built By Hand
The M31 Widebody is the ultimate fusion of exotic power and everyday usability—making it a standout performer in the stern drive category and a true flagship of the DCB experience.
