The 27 x 1.5 mm sprit and 45 x 2.2 mm mast are both made from the highest grade aerospace grade aluminium alloy available. (7075 T6)
The super stiff BLACK GOLD mast and sprit can be used with a choice of booms :
The 32 mm BLACKLITE boom
A bendy boom, which comes with a bridle, will flatten and depower the sail which enables the lightweight sailor to go faster in more wind.
The 40 mm "Standard" and 45mm "Power" BLACKGOLD booms
Offer a stiff and lightweight boom, which comes with a bridle and suitable for the majority of sailors.
The 55 mm BLACKMAX boom
The ultra stiff (and yet lightweight) boom can be used without a bridle. This enables the larger sailor to jump across the boat and not too far aft while tacking.
