Towing...in the rain.....anything i can do??

So I'm heading out for the holiday, only problem is my hometown where I'm leaving from is going to be raining. Its not going to be raining at the lake (5 hour drive).

My custom CS cover that is supposed to be towable, sucks and always comes off when i tow with it.

Anything I can do?

Should I:

1.) Just leave the cover off and let it rain in the boat while towing?

2) Put the cover on and try to secure it additionally somehow?


Has anyone had any luck like duck taping all around the rub rail area where the CS cover ends? Effectively duck taping the cover to the boat, so hopefully it won't slip off when towing?

Or maybe running some straps around the boat and cover to try to hold the cover on??

Also, when you tow with the CS cover, do you leave the rain pole in, or take it out??

Thanks for any help, I'm kinda stressing over this.
