GBR 419 is the latest Mini of this design and finished construction in early 2003. It is built from the latest composite materials, made entirely from carbon fibre. At little more than 800kg it is one of the lightest boats in the fleet and carries around 120 square metres of sail downwind. For ultimate specific strength and stiffness, the hull and deck are built with a stiff sandwich monocoque structure comprising unidirectional laminates and a foam core. A canting keel, comprising of a led bulb and monolithic carbon fin provides the boat with maximum stability at minimal weight, whilst a split foreward tank in the boat can be filled to increase fore-aft inertia and momentum to enhance up-wind performance in rough conditions. A retractable centrally mounted canard is a simple but effective way of providing lift when sailing unwind, since lift from the keel is greatly reduced once swung to windward. This foil is self-gybing, which means it rotates within a fixed casing so that it automatically swings when tacking to give an optimal angle of attack for each tack.

Surfing downwind this boat is capable of reaching peak speeds in excess of 20 knots. Upwind is a different story all together, when going close-hauled a Mini's ability to point is very limited due to its large width and short waterline.

Sailing one of these boats you find they handle much more like a dinghy than a conventional yacht. The helm is incredibly light and responsive, but the rudders are very susceptible to stalling out if the boat is not set-up and balanced correctly. Get hit by a gust downwind with the big kite up and lee helm very quickly becomes weather helm and if you're not quick enough to bear away you find yourself dangling from the guardrails by one hand with the masthead in the water and a few tons and the weight of the ocean trying rip the kite to shreds!
