The Portuguese Carrack - streets ahead of its competition.
A carrack was a large galleon used in the 14th, 15th, and 16th centuries; three masted with the first two square rigged and the mizzen lateen rigged, carrying up to 1,200 tons of cargo, larger than a caravel with higher forecastles and aftcastles. These were also some of the first ships to have heavy cannons mounted on them.
Portuguese ships arrived in the Indian Ocean in 1498, looking for a sea route to the silks and spices of the East. The Portuguese took over many of the existing routes, and controlled the Indian Ocean trade through force of arms. For many years, English East Indiamen competed with the Portugese for the lucrative eastern trade.
Indian historians describe these vessels (and also Caravels) as the bringers of "seaborne terror". As some of the first ships to be mounted with cannons, they would sail into range of major Indian trading ports (such as Kalikut) and bomb the hell out of them, in order to secure outlandish trading rights.
