The Aston – badged AM37 and a joint project with Quintessence Yachts – is the sports boat of the pair with its open cockpit, dashing profile and, in top S form, 52-knot (60mph) top speed.
The Mercedes is more the grand tourer – 10ft longer at 46ft (14m) and with an open-plan cabin that transforms from dining lounge into overnight accommodation for two. It will still rip across the world’s more exclusive bits of water at an impressive 40 knots. Called Arrow460-Granturismo, it’s been created by a new company, Silver Arrows Marine, in collaboration with Mercedes-Benz Style, Daimler AG’s design division that does everything from furniture to helicopters.
And doesn’t it show. The silver (what else?) Arrow460 is definitely S-class shaped, with the same familiar window profile and car-like feature lines down the side. The side windows even slide down into the hull at the press of a button while all the cabin glass can be darkened electronically so the sun never gets too much – just like the glass roof of the Mercedes SL.
There’s a very “James Bond” touch too with a glass roof section that rises up on hydraulic struts, opening up the cabin to the sea breezes in a way that Silver Arrows Marine says has never been achieved before in this size of yacht. When moored up, another button operates the retractable diving platform that extends from the boat’s stern.
