To provide a stern draft measurement tool capable of safe draft confirmation without having a measuring person venturing outboard and capable of measuring accurate draft measurement even in a position where an outboard plate in a stern with a complicated flared configuration in a vessel stern area does not come into contact with the sea surface.SOLUTION: A stern draft measurement tool includes: a letter display unit arranged below a pillar pipe hung down from a vessel stern side; a transparent pipe arranged on a surface of the letter display unit and arranged to have a float floating on a sea level position of sea water intruding inside from below; and a reflection unit sliding vertically along the pillar pipe and simultaneously reflecting both a displayed letter of the letter display unit and the float.SELECTED DRAWING: Figure 2
【課題】計測者が舷外に乗出すことなく安全に喫水確認を行うことができ、船舶船尾域の複雑なフレアー形状の船尾の舷側外板が海面に接しない箇所についても正確な喫水数値の計測を可能とする船尾喫水計測用冶具を提供する。【解決手段】船尾喫水計測用冶具において、船舶船尾舷側から吊り降ろされる支柱管の下方に配置される文字表示部と、当該文字表示部の表面に配置され、中に下方から侵入する海水の海面位置で浮遊するフロートが配置される透明パイプと、前記支柱管に沿って上下にスライドし、当該文字表示部の表示文字及び前記フロートの双方を同時に反射する反射部とを有する。【選択図】図2
