I don't understand why people keep saying that the FX-1 is so much lighter than the Hobie 17 SE.
The class weight for a Hobie 17 is 330lbs (149.7kg) with wings. At the Mega last year, several boats were even less.

According to the Hobie Europe website, the FX-1 with ONLY a mainsail (no wings) weighs 140kg(308.65lbs).
With main & spi(no wings), 148kg (326.28lbs)

The Hobie U.S. website simply list the FX-1 as "weight: 275lbs".
It lists a "gennaker", "Jib kit", and "Spinnaker kit" as "Optional Features"

There are three different wing designs:
The "Sport Wing" is actually just a short rack, no fabric, which widens the boat by 12 inches on each side and weighs 10lbs each.
The "Comfort Wing" is similar to the "Sport Wing", but larger and has fabric to sit on and increases the beam by 24 inches on each side and weighs 18lbs each.
The "Classic Wing" is very similar to the Hobie 18 SX wing and are as comfortable as the H17 wings.
It increases the beam by 24inchs on each side and weighs 29lbs each.

So according to EuroHobie, an FX-1 with a spi and "Sport Wings" would weigh 346.28lbs.
With "Classic Wings" would weigh 384.28lbs!!!!

I saw the FX-1 at the Mega last year and tried to pick it up. It felt every bit as heavy as my H17.

WHAT IS THE TRUE WEIGHT OF THE THING?
