在船体外表面有多种标志，主要有：Thereareallkindsofsignoutsidethehullsurface,mainlyinclude:吃水标志

Draftmarks船舶旳吃水标志（DRAFTMARK)叫水尺。它绘在船首.尾及船中两侧船壳上，俗称六面水尺。Theship'sDRAFTmarks(DRAFTMARK)calledDRAFT.Itdrawattheendofthebow.Andonbothsidesoftheshiphull,commonlyknownasthesixsidesdraft.水尺采用米制，用阿拉伯数字标绘；采用英制水尺时，采用阿拉伯数字或罗马数字。字高.字间距.水尺读法如下图。DraftsurveyUSESthemetricsystem,useArabicnumeralsplot;UsingEnglishdraft,willusetheArabicnumeralsorRomannumerals.Word.Wordspacing.Draftlawthediagrambelow.两种制式旳吃水标志对比图。Draftmarkscontrastfigureofbothformats.2.载重线标志
