Maybe I'll stick with the old Mirror, though she needs a little TLC.

Seems the best idea to me for what you want to do, except that obviously you
won't be able to get it up the cliff (not easily, anyway). If there's some
way you can keep the boat on the beach it becomes ideal - I'd much rather
leave a slightly knackered Mirror lying about than a new dinghy I'd just
bought.
