The 390 is a sweet spot boat for Marex, inspired by the flagship 440. It condenses that down to a more manageable 12 metre (39.4ft) platform. YachtBuyer Jack Haines - Sept 2025

And it just reeks of quality...from the stainless steel as you work your way forward to the beautiful woodwork, the cappings on the bulwark here, the teak as it runs forward, the handholds. It is lovely. YachtBuyer Jack Haines - Sept 2025

Handling is just glorious. And what is really pleasing… it’s genuinely really fun to drive. YachtBuyer Jack Haines - Sept 2025

But with its conceptual clarity, its build excellence and its promise of rock-solid residual values, those with the money and the ambition can rest assured that the new Marex 390 is one of the best 40ft sports cruisers we’ve seen. Motor Boat & Yachting Alex Smith - Feb 2026

As an all-round package without going up to the 440, the 390 is very hard to beat.
