Modern sails must have the right mast to work.
There are industry standards in length and stiffness, but bend curves change between brands. Some masts work better with some sails, so it's best to ask us what's best.
SDM masts - traditional diameter masts with a 48mm internal base diameter - still the best for larger sizes and freeride/slalom sails.
RDM masts - reduced diameter masts are much stronger and are now the norm for use in wave sails. They give the sails are really nice soft feel also which light sailors love.
Please Note - some boom clamps require a rubber sleeve adapter for use with RDM masts and you will need a RDM mast base extension.
