About this tender
The wallypower58X is the build we ask Wally for when your programme needs a fast day-boat that can hold its own aesthetically alongside the mothership. It takes the wallypower58 platform - deep-V hull, glass and carbon dome hardtop, the signature flush-deck aesthetic - and re-engineers the transom for outboard power. Four Mercury V12 Verado 600hp units replace the inboard driveline, putting 2,400hp on the stern and a certified 50 knot top speed within reach of a twelve-person complement.
The shift to outboard propulsion is not simply a packaging choice. Wally cites a reduced running draft compared to the inboard model, which makes the 58X workable in shallow coastal anchorages where the standard 58 would be more cautious. The Mercury rotating gearcases and joystick system add precision docking capability that owners and captains will appreciate in busy marina berths or when coming alongside a swim platform in any kind of chop.
Removing the inboard engines frees meaningful volume below decks. The 58X retains the wallypower58's accommodation for one or two couples, and the aft section is recovered by folding bulwarks rather than being given over to engine servicing. The hydraulic passerelle, first introduced by Wally on the 48X, is built in as standard - a detail that matters when the boat is used as a daily tender or water-toy platform rather than purely as a fast passage-maker.
With 4,100 litres of fuel capacity and a cruising range of 320 nautical miles at 38 knots, the 58X sits in a credible position between a pure day-boat and a serious coastal cruiser. Wally quotes RINA Class B+F certification, which gives the classification substance a project manager needs when integrating the vessel into a flag-state compliant fleet.

Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
Four Mercury Verado V12 600hp outboards deliver a combined 2,400hp. Wally specifies this as the first application of the Mercury V12 Verado on the 58-series hull, pairing the engine's rotating gearcase joystick system with the deep-V platform for precision low-speed handling alongside the performance numbers.
The deep-V hull reaches 50 knots at full power; cruising speed is quoted at 38 knots with a range of 320 nautical miles. The 4,100-litre fuel capacity underpins that range figure, making this viable for extended coastal passages without a fuel stop.
The outboard configuration produces a shallower running draft than the inboard wallypower58, according to Wally's published specification. The 1.3 m static draft figure is confirmed in the technical sheet, giving the boat credible access to anchorages that a deeper-running performance yacht of this size could not enter.
The hydraulic passerelle is integrated into the hull structure, not a bolt-on addition. Wally pioneered this feature on the 48X and 43X; the 58X carries the same approach forward, making water entry and exit safe and straightforward whether the boat is at anchor or alongside a superyacht swim platform.
The wallypower58X is certified to RINA Class B+F, providing the classification society endorsement that flag-state compliance and insurance underwriters typically require. This distinguishes the vessel from unclassed performance boats of comparable specification.
