About this tender
The wallytender48X is the build we ask Wally for when the brief calls for a 15.0m tender that genuinely earns its outboard configuration rather than wearing it as an afterthought. The hull is a deep-V form developed jointly by Wally and the Ferretti Group engineering department, carrying twelve people under RINA Category B certification; the transom is engineered to accept up to four Mercury outboards, and the outboards tilt up to reduce draft to 700 mm for tight inshore work. That combination - proper offshore hull, practical shallow-water capability, and a deck layout that functions as a dayboat - is not common at this length.
Standard fit is four Mercury Verado V10 425 hp units, giving 50 knots top speed and 360 nm range at 34 knots. Owners who want the full performance envelope can specify four Mercury Racing V8 500R units instead; Wally quotes 56 knots top speed on that configuration, with cruising range of 320 nm at 36 knots. The spec sheet lists unladen displacement of 11,500 kg and laden displacement of 15,300 kg, with a 2,800-litre fuel tank supporting both range figures. We'd note that the laden-to-unladen delta is meaningful - keep that in mind when calculating davit and garage loads.
On deck, the 48X follows the same layout logic as the inboard wallytender48: folding aft wings extend the cockpit footprint when at anchor, the walkaround flush deck provides clean access forward, and a combined passerelle and bathing ladder is retained despite the outboard transom arrangement. Below, carbon-fibre steps lead to a double V-berth cabin with sofa seating, a vanity unit, and a separate shower room and heads - enough for a confident overnight passage rather than just a day away from the mothership.
Classification is RINA B plus F, which covers open-sea dayboating and coastal overnight use across the programme. The technical sheet is marked as preliminary data, which is standard practice for a model at this price point; we recommend confirming final figures with the yard at the time of order.

Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
With all four outboards trimmed up, draft reduces to 700 mm. That is a practical number for Bahamian sandbanks, Sardinian coves, and the shallow approaches common to Mediterranean charter grounds - without any penalty to hull form or offshore performance when the engines are down.
Substituting four Mercury Racing V8 500R units in place of the standard Verado V10 425 hp engines raises top speed from 50 to 56 knots. Cruising speed moves to 36 knots on that configuration, with 320 nm range. The chassis and transom are already rated for it; it is a factory option, not a custom modification.
At 2,800 litres of fuel, the 48X carries enough to run 360 nm at cruising speed on the standard engine fit. That is meaningful for a tender of this size and allows genuine point-to-point passages between ports rather than range-managed transfers.
Dual certification covers offshore passages and coastal cruising within a single registration. For captains managing a mixed programme - open-water transits and sheltered anchorage work - this avoids the administrative friction of restricted certification.
The hull form is a balanced deep-V developed by Wally and Ferretti Group's engineering team, providing stability in offshore conditions. The folding aft wings extend the cockpit footprint at anchor, giving the 48X the deck space of a larger boat when it matters without the length penalty underway.
