I have read on Wikipedia (well, who hasn't) that it was very hard to sail past the tropics from North to South and vice versa without hugging the trade winds, by sailing near the coast of the Equator spanning continents like Africa and South America. This had a lot of impact on the movement of ships and the resulting sea route.
Let's just say that on a certain Earth-sized planet, most of the planet's landmass is concentrated on the Northern Hemisphere, meanwhile on the Southern Hemisphere there is only an Australia-sized mini-continent located at 50-60 degrees latitude. (Just like New Zealand) No chain of islands is connecting the mini-continent with the Northern continent. There also is no equator spanning continent or island.
Now for the question
If the planet's inhabitants had the same maritime technology (ship building, navigation, etc.) as the Age of Sails, will they have difficulties locating the mini-continent? And/or sending ships from the Northern Continents to colonize it?
Even the Maori colonized New Zealand from their Pacific ancestral island, and the British didn't seem to have any significant difficulty claiming remote islands as Her Majesty the Queen's realms.
