About this tender
The Windy SLR-SR60 is the build we ask Windy Scandinavia for when your programme demands genuine long-range independence alongside a superyacht. At 18.15 metres, with a fuel capacity of 4,050 litres in SLR configuration, it achieves approximately 800 nautical miles at 25 knots - a figure that puts most chase boats in a different category entirely and removes the range anxiety that dogs shorter, lighter alternatives.
The collaboration behind this boat is worth understanding. Windy's previous excursion into the superyacht sector produced the SR52 Blackbird, and Malcolm McKeon Yacht Design was central to that model's reputation. The SLR-SR60 continues that relationship, adding Studio Liaigre for the interior - a Paris-based practice whose work in the yachting industry is synonymous with refined materials and considered detailing rather than showroom gloss.
Hull geometry was validated by Cape Horn Engineering using CFD analysis across multiple sea states. The brief was explicit: minimise spray ingress at speed in open-water conditions. The result is a generous bow flare combined with multiple chines and spray rails, giving the SLR-SR60 the dry, composed ride that genuinely offshore passages require. This is not a boat that was optimised for flat-water press photography.
Two variants sit within the same hull: the SLR60 with three berths and the extended 4,050-litre fuel tank, and the SR60 with four berths and a 2,700-litre tank rated at approximately 500 nautical miles. Both are built at Windy's yard in Sweden and carry CE Category B certification. The SLR60 is the one we would specify for owners whose mothership regularly crosses ocean passages or operates without fixed marina infrastructure.

Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
The SLR60 variant carries 4,050 litres of fuel, giving an approximate range of 800 nautical miles at 25 knots per Windy's published specification. That figure is materially higher than comparable 18-metre chase boats and removes the need for regular fuel stops on extended coastal or offshore programmes.
Malcolm McKeon Yacht Design, the practice behind the original SR52 Blackbird, is responsible for the naval architecture and exterior styling. Cape Horn Engineering conducted CFD-based design optimisation across sea states, focusing specifically on spray suppression through bow flare geometry, chine placement, and spray rail positioning.
The interior fit-out is signed by Studio Liaigre, Paris. The practice's involvement lifts the finish standard to one that is credible alongside the main yacht rather than merely functional. The SLR60 offers three berths; the SR60 variant reconfigures the same volume to accommodate four.
The helm station sits within a fully enclosed structure with large sliding doors spanning approximately 20 feet of the beam. This arrangement gives the crew genuine all-weather operability while allowing the guest area to open fully in settled conditions - a practical detail that shorter, open-format chase boats cannot replicate.
The SLR-SR60 is certified to CE Category B, covering offshore passages in significant wave heights up to four metres. Commercial Vessel Registration as a Small Commercial Vessel is available upon request, which broadens the operational permissions for charter or crew-carried programmes.
