How about 15 sq. mtr. main, 17.5 sq.mtr spi, 16.5 foot long 28 foot mast 8'2" wide and 104 kg all up when in singlehanded use.

All that combined with an established class, several builders the world over, approaching official international recognized status and already beating A-cats around the course for only 75% of the costs of a new A and halve the cost of that new imaginary all carbon 90kg/18 footer!

Speed difference is not that big about 7 points under Texel between the F16 and new 18sq + spi = about 3 minutes per 45 minute race if you can hold her down singlehanded.

Alot of things can be said about the F16's but nobody is calling them underpowered in 1-up mode. I would not install a bigger engine on a lighter boat even if I got it for free.
