Don't know that one, but part of our enclosure (the front three panels) is Makrolon -- probably similar, it's also like EZ2CY -- and it's great for visibility.
Our original enclosure was all Stratoglass. The current
aft portions are a similar sheet vinyl, can't remember the brand name of it off-hand... but it comes with the same pros/cons.
Stratoglass will roll up, and that can be an advantage is some cases. The coating needs care; not difficult, but you have to follow their recommended cleaning
regimen or it will scratch. It can also scratch if rolled up dry, unwashed. That's manageable... but it's also best to wash both surfaces before rolling, and even better to insert a fabric
of some sort in between the surfaces as you roll.
Makrolon and EZ2CY are rigid, so opening usually works best if you can pin up the opening end, snap it to something like a hardtop. If Cool to Sea is similar, that might be your best plan.
Our design has evolved a bit, so our next iteration might include more Makrolon.
Imagine three rigid front panels
, 4 sheet panels
on the sides, 3 sheet panels aft. The center rigid panel unzips on the bottom and two sides, then pins up to the hardtop. All the other panels have U-shaped roll-up sections. I'm inclined to experiment
with almost all rigid panels, with zips on all 4 sides, so a complete panel can be easily removed and stowed flat. (But that also means needing room to stow flat panels.)
FWIW, all our zips are also covered by a flap that's hook-and-eye'd over the zip; the flap keep salt
out of the zipper, and it also add strength to the whole enclosure during high winds. (That's been proven out, here.)
Another FWIW: #10 YKK zipper suck. Not much alternative, but they're nasty buggers. Zips used for curves, as in a U-shape "smiley," ought to be coil zippers, instead. I mention that simply because I see so many struggling with #10 YKKs when they're not made to go around curves.
