The new Foil Drive FM+ 430 battery is 17% lighter than the MAX High Power and runs five minutes longer, in a unit making 20% more thrust. We've run the whole range on weight-to-power, then put it alongside the Duotone Foil Assist.

Worthing Watersports will be at the Duotone Experience Day in Poole Sandbanks this Saturday, trying the full 2027 range. Wind's forecast light, so it's a great day to grab Sam for a proper chat about kit rather than watch him disappear downwind.

The 2027 Cosmic 4 SLS brings the World Cup wave shape updates — more nose rocker, refined tail outline and reworked tuck line — to a stock board in four sizes from 76 to 94 litres.

Foil Drive's Gen 2.5 range has landed: a new Assist MAX+ with 20% more thrust, FM+ batteries that finally cross between the MAX+ and the Fusion, and a free power upgrade for every Fusion out there. Every question we expect to be asked, answered with the numbers.

Duotone's next UK Experience Day lands at Sandbanks on Saturday 26th September — free entry, demo stations, team riders and the full 2027 range. Sam and the WW team will be there too, come find us.
