This sundancer got new tops and enclosure panels all around . We remade the front bimini for better height and water flow. Sunbrella Marine, 40 mil O’Sea Marine clear, Solarfix PTFE thread were used for materials. An easy access J-zipper with overlapping flap was built in to the side panels and aft entry. These pull back and snap to themselve isntead of rolling up to wrinkle the nice clear vinyl on the panels.
