I've always used the existing cover and straps if possible. Some times the cover is good but the straps and buckles are not.
Barring that I've used any chain I can get my hands even as light as kick dog chain.
Throw that over either the existing cover or your plywood and screw it to the sides of the hot tub.
I get very few hot tubs myself.
The last initial secure had one but was covered with about 2' of ice from the snow melting and refreezing.
