For example, if a vessel has a GRT of one hundred,000 and a passenger capacity of three, 000 the area ratio could be 33. Averaging twenty-five to thirty, some ships have space ratios as high as sixty, others as little as ten. The measurement of the ship does not necessarily correlate with space ratio; a small luxurious cruise line might have a excessive house ratio because few passengers are carried, whereas a megaship that carries many passengers might have a low space ratio despite a high GRT. From 1990 to 2000 cruise vacationers expanded in quantity from 3.5 million to over 8 million per yr, with Americans accounting for eighty % of cruise passengers worldwide. In this same period, the variety of cruise ships plying worldwide waters elevated from ninety seven to one hundred seventy, and the variety of cruise ship berths virtually doubled from 68,474 to 127,943.
