1.3 Boat weight

The minimum weight of the boat ready to sail, excluding non permanently fitted wings, is fixed at :

1.3.1 Singlehanded mode (cat rigged with gennaker) : 104,0 kg. (= 230 pounds)
1.3.2 Doublehanded mode (sloop rigged with gennaker) : 107,0 kg. (= 236 pounds)

So min. weight excludes the wings / racks. Just have to make them really light then, eh ??
