A Class Cat Carbon Boom: Sheave Box

Carbonix > Blog/News > A Class Catamaran > A Class Cat Carbon Boom: Sheave Box
The box is an ‘off the shelf’ part that we can offer from our own mould, made to take a standard sheave.
It is half the weight and stronger than a steel box.
Exit holes can be drilled at either or both ends and different pin sizes are possible.
This is an experimental installation in a minimum diametre boom.
Epoxy glue with no secondary bonding was used and, so far, after several sessions in max wind conditions, there are no signs of problems.
Contact us to get one or for a complete installation.
