(Right)Specific Design Characteristics of Fins:
" Size or surface area of fin blade.
" Stiffness of fin blade.
" Configuration or shape of fin blade - length and width.
" Integral footbox versus strap-type fin.
" “Offset” or angle of pitch between footbox and fin blade.
" Buoyancy of fin.
Physical Attributes Influencing Fin Selection:
