How about a NMB rating for the SC20 TR with spi of

Light weather 88
heavy weather 92

SC20 TR no spi :

light 91
heavy 96

Compare to US I-20

Light 92
heavy 95


Seems a whole lot better doesn't it ?


I used the following specs (please give me the correct one if they are wrong)

weight 200 kg (441 lbs)
length 6.10 mtr (20 foot)
width 3 mtr (10 foot)
Mast 11.5 mtr (38 feet)
Mainsail 22 sq. mtr. (236 sq. ft.)
Jib 6 sq. mtr. (65 sq. ft.)

And I only needed 60 seconds to acquire a rating and that included looking up estimates of the specs via internet


Is that satisfactory ?
