  • the sealing element 42 is designed as a sealing sleeve 43 and has an opening 44 through which the connecting means 24, in particular the cast plastic 25, can be introduced into the intermediate space 19 between the coker tube 10 and the receiving shaft 11.
  • the connecting means 24 After the connecting means 24 has hardened, the sealing sleeve 43 can either remain on the outside 14 of the hull 12. Alternatively, it is possible for the sealing sleeve 43 to be removed from the outside 14 of the hull 12.
  • the Fig. 6 and 7 show another rowing trunk 100.
  • the rowing trunk 100 has a receiving shaft 11, which is arranged on a hull 12 of a watercraft 13.
  • a trunk pipe 10 is arranged in the receiving shaft 11 in such a way that a gap 19 is formed between the outer wall 17 of the trunk pipe 10 and the inner wall 18 of the receiving shaft 11.
  • the trunk pipe 10 is arranged in the receiving shaft 11 over a clamping height 45. In a lower area 46 of the clamping height 45, the intermediate space 19 between the inner wall 18 of the receiving shaft 11 and the outer wall 17 of the coker tube 10 has a constant gap dimension 47.
  • a central region 48 is provided above the lower region 46 of the clamping height 45, in which the gap dimension 47 between the outer wall 17 of the coker tube 10 and the inner wall 18 of the receiving shaft 11 increases in the direction of the hull 12.
  • the coker tube 10 has a wall thickness 49 that decreases towards the top.
  • holder elements 21 are arranged on the outside of the coker tube 10.
  • Corresponding holder complements 22 are arranged on the inner wall 18 of the receiving shaft 11. The holder elements 21 or holder complements 22 reduce the gap size 47 in the upper region 50 of the clamping height 45.
  • a circumferential flange can also be provided.
  • a connecting means 24, such as cast plastic 25, is arranged in the upper region 50 in the region of the holder elements 21 and holder complements 22.
  • a connecting means 24 is also provided in the lower region 46 of constant gap size 47.
  • the middle region 48 of the clamping height 45 is the middle region 48 of the clamping height 45, whereby the gap 19 in the middle region 48 is not filled with a connecting means 24.
