I've done some digging, and now I know how things stand.

Wikipedia:
Leeuwin ("Lioness"), also spelt Leeuwine in some Dutch East India Company (VOC) documents, was a Dutch galleon that discovered and mapped some of the southwest corner of Australia in March 1622. It was captained by Jan Fransz[1] and was the seventh European ship to sight the continent.

When it is spelt Leeuwine it has to be Leeuwinne.
