I think the smaller of the two jibs shown in Mikes' drawing is the 'official' number 1. that is certainly the size of sail I have. Note how high the foot is cut - very easy to see all around! This also ties in with the sail dimensions shown in the handbook. I fitted my number 1 with small mainsail slider bullets instead of piston hanks so that it works on the Rotostay. My number 2 has about 9 sq m, about right for area but I bought it to set on an inner forestay,so it has a slightly different shape to that shown in the handbook. For info, the handbook says the number 2 is 6.86m luff, 5.23m leach and 3.54m foot.
