For boats of that era, as I recall
things, the inventory might go like this (at least, this was how our old Standfast 36 (IOR one tonner from 1974) was set up):
#4= 100 (full hoist, which in my parlance made it a blade. If less than full hoist it would have been called a working jib.)
(about 100 sq ft)
When we went cruising in that boat we took the light #1, the #3, #4 and the storm jib
. The #3 was the work horse... got lots of miles on it. Seldom used the #1 because it was a deck
sweeper and blinded the helmsman through a big sector (I'm still embarrassed by the time I hit a huge tanker mooring
buoy in the La Paz
channel when using that sail!).
When I finally overcame my prejudices and bought a furler
, the sail I had made for it was about like the #3 in size. Eventually added a inner forestay and a hank on staysail for going to windward in 25+ true. Not a bad set up...
