Description

Selden Alto Mast for Fireball

All Seldén dinghy mast sections have been designed to give the best stiffness to weight ratio available in an alloy extrusion.

Seldén have worked with some of the top Fireball sailors to develop the most complete range of spars for the class.

Material, section shape and size, and wall thickness all have a major effect on both the static and dynamic bend characteristics of a tube. These details are studied in the design of every section and are carefully checked on every piece of spar tube Seldén use.

Alto is 5% stiffer than Cumulus it is used by heavier teams looking for extra power in marginal conditions.
