I'm not 100% sure, but the "protect-a-glaze", and/or Innsbruck look best to me.
Both, and/or all will work, depending upon what final finish you want, and what scale your minis are.
There are a few other ones too, that I'm not seeing listed, e.g. one that is quite smooth, with very thin/small swirling to it, best for relatively calm water, and/or smaller scale minis.
The other one, that I think I used, doesn't seem to be listed either. It has larger "swells", and/or random humps in it, which are deeper, and much more widely spaced than the patterns shown in the images.
It is used for old bathtub and shower doors, and has a more rippled effect.
I'm sure if you do a bit of searching in Philly, you'll have a local plastics store there, or in NY, that can provide what you need.
They may even provide free samples, like TAP does, from their scrap bins. Probably best to see the stuff in person, but it you can't do that, ask them to send you some small squares, suitably labeled, for you to review.
All are sold in 4' x 8' sheets, and they charge by the square foot, and for each cut, but one or two long cuts, in the width desired shouldn't cost too much, even if you have to get them to do that, and ship it to you, since it's pretty thin, and lightweight.
Various thicknesses are offered, but I suggest 1/8" is good for most applications.
Some sheets will come as thin as 1/16", but I'm not sure if they sell the patterned ones that thin.
On all, one side is textured, and the other is smooth.
I painted mine blue on the smooth side, and left the rough side up, so with the acrylic shine still showing, it makes it look wet.
Others paint theirs, so it's up to you.
With the shower-door pattern I mentioned above, you can even paint white on the top high points, to represent whitecaps on the sea.
