result of the effects of the costa concordia incident and the continued instability in the european eco- nomic landscape . however , we continue to believe in the long term growth potential of this market . we estimate that europe was served by 102 ships with approximately 108000 berths at the beginning of 2008 and by 117 ships with approximately 156000 berths at the end of 2012 . there are approximately 9 ships with an estimated 25000 berths that are expected to be placed in service in the european cruise market between 2013 and 2017 . the following table details the growth in the global , north american and european cruise markets in terms of cruise guests and estimated weighted-average berths over the past five years : global cruise guests ( 1 ) weighted-average supply of berths marketed globally ( 1 ) north american cruise guests ( 2 ) weighted-average supply of berths marketed in north america ( 1 ) european cruise guests weighted-average supply of berths marketed in europe ( 1 ) .

( 1 ) source : our estimates of the number of global cruise guests , and the weighted-average supply of berths marketed globally , in north america and europe are based on a combination of data that we obtain from various publicly available cruise industry trade information sources including seatrade insider and cruise line international association ( 201cclia 201d ) . in addition , our estimates incorporate our own statistical analysis utilizing the same publicly available cruise industry data as a base . ( 2 ) source : cruise line international association based on cruise guests carried for at least two consecutive nights for years 2008 through 2011 . year 2012 amounts represent our estimates ( see number 1 above ) .
