Section Selection

Your choice of spar section is critical to performance. Material, size, wall thickness, weight and shape affect both static bending characteristics and dynamic characteristics ("gust response").

Selden design their sections to take class rules to the limit: - for example the Olympus boom section was designed to be simply the stiffest 470 boom possible within class rules.

Whatever your class, the extensive Proctor section range ensures that there is a mast and boom available with optimum performance. For recommendations for your particular class, please consult our specific class data sheet.
