Lower vertical centre of gravity (VCG) results in: Reduced pitching moment; For the same ballast, switching to a carbon rig results in a stiffer boat which can carry more sail and accelerates faster.
Boats which are designed with carbon rigs need less righting moment - draught or costly ballast can be reduced.
Lower mass means lower momentum - mast pumping due to seaway motion is reduced and safety is increased.
Superior stiffness/strength characteristics - A carbon fibre mast will bend far more before it fails compared with an alloy section.
Aluminum alloys are notorious for their susceptibility to fatigue failure, especially when compared to the impressive fatigue resistance of carbon fibre sections.
Altogether; carbon fibre gives you marked improvements in safety, comfort and performance.
