Hello - Shortly I'm going to be getting plywood for my RowCruiser Build. I've noticed one source mentioning 4 mm panels being used for the hull, and another stating 6 mm. Which is the better thickness to use for the hull?

Hi Richard. Originally, we recommended 6mm plywood for the RowCruiser hull panels with fiberglass just on the outside and just glass strips (along the seams) and an epoxy seal on the inside . We then tested 4 mm panels with full glass on both sides, and found strength was about the same (or even a little stronger) with a lower cost and slightly less weight. Overall, both ways are fine, allowing greater flexibility depending on available wood, however, 4 ml is probably slightly preferable.
