The local guy went from never sailed one to 10th in the world in a little over 2 years. The impressive part is he didn't have anyone to sail with in the beginning but now a fleet is steadily growing.
two months should get your around the course with a couple of swims at the most, if the breeze is steady. The new boats have inflatable pockets under the wings, seems to help them a lot getting going.
The moths have a lot going for them, 1/3 the weight of a f16 (1/5 an f18), 1/2 the cost of a new one, and at very least comparable speed.
good on them for being truly development class, it certainly hasn't hurt them in the long run!
