The use of carbon in the nautical sector has a number of advantages.
One of these is the inertia of the material to common marine corrosives and sunlight (provided that the accessory has been cured in the autoclave).
Metals and woods need maintenance to preserve their value, functionality and aesthetics over time.
Carbon composites remain unchanged over time, even in the absence of maintenance.

The TCO (Total Cost of Ownership) still rewards carbon composites.
