About this tender
The wallypower58 is the build we ask Wally for when a programme needs genuine offshore range in a hull that carries its own design authority. At 17.3m LOA with a Volvo Penta D8 IPS 800 driveline, it reaches 38 knots on the optional upgrade and holds 32 knots at cruise with 320 nautical miles in hand. That combination sits well above what most dayboats of this length will deliver, and the unladen displacement of 24,500 kg tells you this is a serious, fully-fitted vessel rather than a stripped performer.
The deck arrangement follows the logic Wally established on the wallypower118: clean, uncluttered upper surfaces with volume prioritised for use rather than show. A large cockpit with a polygonal dining table and deep sofa, wrap-around glazing, and a retractable electrical awning that lifts clear of the deck give the wallypower58 an indoor-outdoor flexibility that shorter day-cruiser formats cannot match. The aft platform lowers hydraulically at the touch of a button, and a convertible passerelle-bathing ladder is concealed in the stern - both practical considerations for any owner who intends to use water toys regularly.
Below, the layout delivers a true double cabin forward with an en-suite shower room, while the optional configurations extend to a guest cabin or a single crew berth, each with access to a second shower and day head. Natural light enters via overhead glazing and Wally's camera-fed Magic portholes, keeping the hull side clean and reducing the going-alongside risk that conventional portlights create. Certification is RINA Class B plus F, confirming the vessel is rated for offshore and inland waterway use under Italian flag classification.

Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
The standard fitment is a single Volvo Penta D8 IPS 800 at 600 hp; the optional upgrade to IPS 800 drives pushes top speed to 38 knots. At the 32-knot cruise figure the hull carries 3,000 litres of fuel, enough for a manufacturer-stated range of 320 nautical miles.
The aft platform lowers into the water on demand, simplifying tender launch and retrieval without external lifting gear. A convertible passerelle-bathing ladder is integrated into the stern. Both features reduce the deck clutter that a conventional bathing platform arrangement would introduce on a 17-metre hull.
Wally routes camera feeds to interior screens it calls Magic portholes, giving below-deck spaces a sense of natural light while leaving the hull topsides completely uninterrupted. The practical benefit is reduced risk when going alongside, as there are no external portlight rings or frames to catch on dock furniture.
The wallypower58 carries RINA S.p.A. classification to Category B and F, covering offshore sea conditions and inland waterways respectively. For captains operating under Italian flag or requiring a recognised classification society certificate, this avoids the administrative step of a separate post-build survey.
