Thanks for ALL the suggestions - everybody.
My main concern is, 6 sets of casement windows which face the water. That is, 1st floor has 3 48" high by 96" units (4 crank outs per unit) and the second floor has the identical complement of 3 - 48" by 96" units of 4 crank outs each).
I'm "THINKING" of 1 - 4' by 8' sheet of 5/8" for each unit with some kind of "strapping" to fasten each unit. Think of the Roman Numeral for 2 or 3 (II or III) over each plywood sheet extending, maybe 6" or 8" (i.e. 60 inch 2x4 screwed to each sheet then fitted over permanent (weather protected anchor bolts(?) and bolted on before threatening weather.
I'll try to fiiger a way to post a photo of the existing windows and a drawing of my suggested (?Rube Goldbergian?) solution later today.
BTW: I did ALMOST have a an agreement with another domestic insurance company but they wanted storm shutters over EVERY window and door in the house. I didn't consider their suggestion reasonable. (Criminy, I'd be more likely to break my neck installing the damned things than I would losing the windows to wind.)

Secure them to the channels with bolts.
You'd have to put some permanent anchors into the walls, but then you could remove the C channel.
Not sure how much money it would cost to do it though....depends on how many big windows you have to protect.
