The F16 threatens the "big" two and a half because it exposes the lie that catamarans have to be built to 1970's-80's weight to be affordable.
Several of the F16 builders have proven that this is not the case.

If the evidence ever sinks into the thick brain washed heads of the sailing public their masquerade will be exposed for what it is. The fact is; you can have a strong light efficient boat for the same price as a lead sled disguised in a modern design.

The extrapolation naturally takes you to; If they can build a F16 light weight, then what in the world are we doing accepting a 400lb 18' cat or a 13' roto-mold low performance cat that weighs as much as an F16? Thinking sailors will move towards the F16 concept, and forward thinking classes like it...the sheep will continue to follow the crowd over the cliff.

Catamaran sailors would never buy a new cell phone that was as big and cumbersome as those of the 1980's, nor would they own a computer that had the attributes of a Commodore 64, why they will accept a low tech 1970's boat molded in a modern shape will forever escape me when alternatives exist.

If weight is no issue why has Hobie Europe offered 6 catamarans less than 4 meters in size yet people are still moving forward with the F12 concept?

Why would the big 2-1/2 want to undermine the F16?... If other builders are building to F16 specs (or extremely close to them) it leads us to believe that the big 2-1/2 chooses not to. Apathy? Ineptitude? Laziness? Greed? Arrogance? Only they know for sure why they don’t put out a product that rises to the F16 concept.
