Installing the Canvas Boot
Slide the bimini boot over the folded frame with the Nautique logo
positioned on the side. Feed the velcro straps around the back
frame of the tower and clip together. Secure the ends of the
webbing with the velcro.
Lowering the Tower and Bimini
It is recommended that a towel or other protective material be
placed over the windshield and that two people perform this step.
Fold the bimini as described above. Unscrew the hand knob. As
you lower the tower (using the process described by Nautique),
hold the front end of the bimini up, keeping it in a horizontal
position as it extends out over the bow.
