I typed "what is coated acrylic canvas?" into google, and the first hit gave me this
"A relative newcomer to the boat cover market, acrylic canvas has a traditional woven cloth external finish and a choice of internal coatings of which we stock two: coated breathable and vinyl coated. The coated breathable is waterproof as long as puddling is avoided. It offers long life and good stability with reduced condensation. The external woven finish does mean that the cloth will need occasional hosing down to prevent dirt becoming ingrained in the weave of the fabric. Colours stocked: Black, Navy, Dark Green and Burgundy. Other colours by special order in advance.
The vinyl coated canvas is slightly heavier, totally waterproof but shrinks slightly over time so consideration needs to be given to fixings. Cleaning is as coated breathable acrylic. "
I bought material for a cockpit canopy from Kayospruce, material called Odyssey from their range. Very satisfied with the material and service I received

I would use un-proofed. If the cover is tight and not flat it will not leak anyway.
There are 2 types of proofed acrylic. PU proofed and vinyl.
- The PU coating is quite delicate - you wouldn't want it to be exposed to UV or wear and tear. I've used it for cockpit cushions.
- The single sided vinyl proofing is heavy and I suspect it is hard to stitch but I've not tried it.
Don't forget the UV resistant thread or it will all fall apart in the baking hot summer we're about to have!
