90% of it is no more than 4 layers but it still needs the ability to handle
the corners of box cushions and things that need to be faced with a finished
seam on both sides like awning rails, heavy vinyl window material and some
zippers.

I have no plan to build a full set of sails but may tackle a riding sail and
maybe a storm jib. Also the machine should be able to handle a few repairs
in a pinch.

Mostly though I figure that if it can handle 6 or 7 layers of material with
ease it will hold together longer doing 4 layers on a regular basis.

What in the world are you guys making that requires sewing through six
layers of Sunbrella??? I think the max I've ever done was three.
