Asanalowe m'zaka za zana, dziko loyendetsa sitima linkalamuliridwa ndi ngalawa komanso sitima zamalonda.
Zombo zomwe zimanyamula anthu monga okwera akadakali aang'ono, kupatulapo zombo za nkhondo kuti azitenga asilikali. Anthu amene amakhala okwera ndege nthawi zambiri amagwiritsa ntchito sitima zamalonda pamene akuyenda kuchokera kumtunda wina kupita kumalo ena.
Kuda nkhawa ndi mphepo, kukwera panyanja kumakhala kovuta kwambiri. Chifukwa cha mautumiki a Thomas Newcomen amene anapanga injini ya steam mu 1712, kusintha kwazomweku kunasinthiranso ntchito ya padziko lapansi.
Zojambula pazithunzi zikutsitsidwa ndi injini zamoto. Sitimayo imakhala yothamanga mosavuta, makamaka pamene ikuyendetsa chombo kapena kuthawa ku doko. Sitima zimayenda bwino kwambiri kuposa kale lonse. Malinga ndi mafotokozedwe ena, kugwiritsa ntchito injini za nthunzi pa sitima zinayamba mu 1819.
Anadziwika ndi sitima yoyamba yotchedwa SS Savannah pa May 22, 1819 omwe anachoka ku United States kupita ku doko la Liverpool - England. Ulendowu umatenga masiku 29.
Koma SS Savannah imangogwiritsa ntchito mphamvu yogwiritsa ntchito nthunzi kwa maola 85 pokhapokha pa nthawi yonse ya ulendo. Pafupifupi 12 peresenti ya sitima zonse ndi nthawi ya kutuluka kapena kulowa m'tchire.
Kuwonjezera pamenepo, SS Savannah anagwiritsanso ntchito chinsalucho ngati chombo cha sitimayo. Komabe, ngalawayi inalembetsa zochitika zazikulu kwambiri pa nthawi ya ma steamers kapena fireball.Zomwe zinachitikanso m'zaka za zana la 19 zinayamba kusamuka kwakukulu kwa mayiko a ku Ulaya, makamaka ochokera ku England, ndi cholinga cha America ndi madera ena a ku Britain.
Kugwiritsiridwa ntchito kwa injini ya steam kumapangitsa sitimayo kukhala yofulumira kuti ifike kopita kusiyana ndi kale.
Izi zimapangitsa osowa alendo kukhala osangalala kuti afikitse kudziko limene adalota. Inde mwa kugwiritsa ntchito sitima zomwe zatha kuyenda mwamsanga.
Nthawi ya pakati pa kumapeto kwa zaka za m'ma 1900 ndi kumayambiriro kwa zaka za zana la makumi awiri ndi makumi asanu ndi limodzi ndi nthawi ya golide pakukweza kayendedwe ka nyanja pakati pa makontinenti.
Amuna amalonda amaona izi ngati munda wamalonda wopindulitsa kwambiri. Mmodzi wa makampani a ku UK omwe akufuna kuyendetsa njirayi ndi White Star Line. Kampaniyo yakhazikitsa sitima zonyamula anthu kuyambira 1849 kukagwira ntchito kwa zaka 60 kuti zitumikire njira yotchuka yotchedwa Trans Atlantic. Ngakhale m'zaka zotsatira ndegeyi inayamba kusintha kayendetsedwe ka ngalawa, njira ya Trans Atlantic siidatchuka.
Mzerewu ukuyenda kwambiri kwa alendo omwe akufuna kusangalala ndi ulendo wopita ku nyanja. Mu 1900, a American-Hamburg Company, mwinamwake kampani yoyamba yogwira sitima zapamadzi.
Kampaniyi ili ndi zombo zoyenda mozama kwambiri. Mwachitsanzo, Prinzessin Victoria Luise, yomwe ili ndi mamita 124 ndi mamita 4,409. M'kupita kwa nthawi, kumayambiriro kwa zaka za m'ma 1930, Adolf Hitler akhoza kuikidwa ngati munthu yemwe anali ndi mphamvu yopititsa patsogolo kayendetsedwe ka alendo pa nthawiyo.
Cholinga chake chachikulu mwachitsanzo powapatsa mapepala a holide kwa ogwira ntchito ku Germany, pogwiritsa ntchito boma, pofuna kuyanjanitsa dziko la Germany. Hitler adapempheranso kulengedwa kwa zombo zatsopano pazinthu zosiyanasiyana, kuphatikizapo cholinga cha zokopa alendo.
