Extra X70 Shadow: Oversized Chase Boat for Yachts

A 69’10” (21.3 m) chase vessel such as the Extra X70 Shadow alters tender logistics for larger yachts by consolidating a 430 sq ft (40 m²) aft deck capable of carrying a 17-foot jet tender alongside two waterbikes and two motorcycles, or alternately a 21-foot sailboat plus waterbikes—streamlining launch, recovery and on-deck stowage operations at crowded marinas and anchorages.

Design and operations

Built by Extra Yachts with exterior lines echoing the Fast and Triplex ranges, the Extra X70 Shadow was penned by Lorenzo Berselli of Studio Agon to deliver a family resemblance while adding practical shadow-yacht capability. The design emphasis is on multi-role use: support vessel, day boat, and a near-independent guest platform. That versatility reduces tender shuffle and simplifies supply-chain movements of toys and provisions between mother yacht and shore.

Deck layout and guest flow

The long, open aft deck functions as a mobile garage: folding bulwarks and clear deck options allow rapid reconfiguration between cargo mode and leisure layout. Guest circulation is planned around an enclosed superstructure with panoramic views; meals may be served aft on deck or inside adjacent to the wheelhouse. For cruising programs and short-term charters, that mix of indoor/outdoor dining keeps guests comfortable in varying weather.

Accommodation and crew

In its shadow configuration the boat carries 2–4 guests in one to two staterooms, while two crew cabins with private heads and a combined galley/crew mess support extended days at sea. When offered as a standalone yacht, the hull can accommodate up to four staterooms below decks, making the X70 a hybrid between chase boat and boutique support yacht.

Stowage, toys and mission flexibility

What sets this platform apart is the combination of large aft deck area and optional internal lockers. Standard arrangements allow storage for:

• 17-foot (5.2 m) jet tender or a 21-foot (6.5 m) sailboat
• Two waterbikes and two motorcycles
• SeaBobs, SUPs, foiling surfboards and assorted watertoys
• Optional gym space of 161 sq ft (15 m²) in lieu of small-toy locker

For charter operators and yacht captains, the ability to tailor toy stowage or dedicate more open deck for guest lounges makes mission planning straightforward—no more juggling tenders at dawn like herding cats.

Performance and propulsion

The Extra X70 Shadow pairs the hull form and powertrain for brisk transit. Twin Volvo Penta units rated at 1,000 hp each deliver a cruising speed near 26 knots and a top speed around 30 knots, ideal for rapid repositioning between marinas, bays and offshore playgrounds.

Configurations and customization

The semi-custom nature of the X70 means owners can prioritize either support duties or guest comfort. Typical options include:

• Convert small-toy locker into a gym or additional guest cabin
• Clear aft deck for fold-out lounges and alfresco entertaining
• Folding bulwarks for increased deck footprint at anchor
• Enhanced towing or recovery gear for heavier tenders

Operational implications for charters and marinas

For charter fleets and rental platforms, a chase vessel like the X70 can act as a floating tender base that simplifies guest transfers, water-sports programs and logistical runs to shore. Marinas may need to account for its 19′ beam and tender handling during berthing; captains benefit from the higher speed and onboard workshop space for same-day repairs.

All told, the Extra X70 Shadow bridges the gap between traditional tenders and full-sized support yachts. It’s a practical answer for owners wanting to carry a mini-armada of toys without the footprint of a large mothership, and for charter operators seeking flexible boats that can double as entertaining day boats. Whether viewed as a chase boat or a compact superyacht support, its mix of storage, guest comforts and performance keeps options open for yacht management, captain planning and rental offerings.

In summary, the key takeaways are clear: the Extra X70 Shadow offers substantial aft-deck stowage for tenders and toys, versatile accommodation options, twin Volvo Penta power for fast transfers, and semi-custom layouts for mission-specific fits. That combination affects yacht logistics, charter planning and marina operations alike—think smarter tender handling at destination beaches, easier boat-to-boat transfers on the gulf or ocean, and more flexible activities for guests who want sunseeker vibes, fishing trips or watersports on clearwater coves. In short, the X70 touches on yacht, charter, boat, rent, lake, sailing, captain, sale, Destinations, superyacht, activities, yachting, sea, ocean, boating, gulf, water, marinas, and more—making it a practical asset for modern yachting programs.
