Keel Fin Base Specification

ProBox Keel Fin Base

The above diagram details the key dimensions for the base of a fish-style keel fin. This base design will still allow fore 'n' aft adjustment of the fin. If this adjustment is not needed the base can be made longer to increase the stability of the fin. Due to the width of the base of the fin the shapers mark at the trailing edge of the fin will need to be adjusted at installation time, so that the box will be correctly located. See the separate specification on this page that descirbes how to make this mark adjustment.
