Not had much to do with Multi Hull RIB'S,and I've never driven a Husseycat...although I did have a look around yours at the Boatshow.
Seems they make a lot of being Fuel efficient in their Blurb...?!
Strikes me that's AFTER you get over the Fact you have to FIT/BUY TWO ENGINES in the first place!...WITH all the extra exspence that dictates....not only in terms of Buying and running 2x engines to begin with... but Rigging x2-Serviceing /maintenance x2-plus ect.
To me you could buy one Hell of a lot of Fuel! for THE SAVEINGS made buying Mono Hull! i.e running One Single.... which you just don't have the option of doing with a Husseyat.
Unlike a lot of Mono Hulls where,if you wish you can run either....but even then, I would'nt imagine the money saved??- Fuel saveings/ect would be a deciding pluss factor.

A Wise Man learns by other people's!
