Titanic is the worlds most popular shipwreck, no question.
HMAV Bounty had an interesting story, one that is still being talked about today (that basically Bligh wasn't a tyrant etc).
HMS Endeavour and cooks trip to watch Venus (and check out the Vegemite down under)
KZ-7 (aka plastic fantastic) the first glass fibre Americas Cup yacht. Changed modern sailing forever
QE II as most of us have seen it at some stage in our lives. I remember a large chunk of Auckland used to go down and watch it arrive.
But I all suppose it will depend on how old you are, where you live, what boats you like and how much you like them.
