So the old Nacra design was not full beam but the new design (Infusion) is? What could possibly have been the logic for a catamaran that was not at max beam?

The F18 at 2.6m beam is too wide to tow legally in some countries like Australia.
So the Nacras were released at a 2.5m beam which is legal.
The only problem here was the other F18 manufacturers were willing to take the gamble and released 2.6m boats.

Later on Nacra released an upgrade kit here to widen the boats to the 2.6m beam. I don't know if it is true but I was told that you had to have a tilt trailer before they would sell the kit to you.

Basically unless you have a tilt trailer, or in some states, a special permit the F18s are being towed illegally.

I'd hate to clean up a push bike up with the bow of a hull.
I think Nacra reasoned that they would be partially lible.

I guess there are other countries with the same problem?
