Dependents on where you have the die made (China, USA, EU). Can be as low as 1000 Euro's (China), sadly problem Chinese extruders is that they won't extrude wallthickness that are less then 2 mm and for a mast you really want 1.6 mm (25% weight savings relative to a 2 mm wall mast).

Let me put it this way : having a new mast die made is something that is within reach of the F16 class and its current membership if we are willing to all invest a little. The same is true for other stuff like alu beams. Other classes like the Mosquito's (I believe) have organised mast and beam production inside their class structure and every person can order himself a set (or more) from the class organisation.

I still believe that this is something we need to look at as a class. The superwing is an excellent design but it can be improved upon slightly in one or two areas. It could do with a little more side to side stiffness and having the walls be a 1.6 mm again would help as well.

It is possible if we all will it !
