The tip of the fins is above the canoe body bottom, and they are positioned deep enough so that ventilation in big seas should rarely be an issue.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/setsail.com\/wp-content\/uploads\/2012\/05\/FPB-971-stab-framing.jpg\" alt=\"FPB 971 stab framing\" width=\"600\" height=\"278\" border=\"0\" \/><\/p>\n<p>The stabilizer shaft comes through a transverse frame, and there is a longitudinal girder reinforcing the hull to help dissipate impact loads when the boat runs aground, although with sub-five foot\/ 1.5m draft, running aground should be a rare occurrence.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/setsail.com\/wp-content\/uploads\/2012\/05\/971-stab-mechnism.jpg\" alt=\"971 stab mechnism\" width=\"600\" height=\"344\" border=\"0\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>One of the more difficult design issues is positioning the stabilizer fins.
