Doin some research and want to read a review of a test winning twin cam sail ?
Have a look here at the turbo review - this aussie design smoked the field.
www.severnesails.com/
German Surf magazine absolutely praised it above all others
And while you are at it have a read of the comparative RDM mast extension review
the Severne 30 cm wave grenade RDM mast extension topped the test
(and the carbon one is a thing of wonder)
Aussie designed sails AND hardware smoking the field - got to be a good thing.
I love my 8.6m Turbo! With my 110L FireMove it's an early planing machine. Another plus - thanks to the clew cutout I can use my 170-230 MS carbon boom (sure can't afford a new/bigger one).
Not entirely happy with all the monofilm but the price was certainly right.
