Or better to say, "Malaccamax is a
naval architecture term for the largest ships capable of fitting through the Straits of Malacca. A Malaccamax ship is defined to be, with 18,000 TEUs, of 300,000 DWT, 470 m long, 60 m wide, 20 m of draft. The restriction is caused by the shallow point on the Strait, where minimum depth is 25 m."
Ah, I was late!
