Shipwrecked castaways

Heya fellow songwriters!

I'm currently writing a song about doomed, impossible love, and I need some help with one verse

Should I use:
Shipwrecked castaways without a shore
or:
Hopeless castaways without a shore

I like the former, but I fear it might be redundant. The latter is easier to sing, but does it make any sense at all ? Can one be a castaway if not cast upon a shore?

Should I find a third solution?

Thanks!
