Not sure what you're asking...
Will it fit? Get your tape measure n find out.
Security? Do you mean safety? Could certainly be VERY dangerous in the event of an accident. Or do you mean security against theft?...
Generally a rib would be hauled on a trailer... Years ago I hauled a stand up jetski in an olds cutlass ciera wagon... My gut is that a rib that big ain't likely to work out... I doubt a roof rack would work either. I'd get a trailer.
