      the designer must be a navigator, as he has his own berth at the navigation station. This is a big cutter intended for cruising. Hull design is traditional, as are the finishing touches, such as actual belaying pins and a Samson post.
    • 2002, The American Practical Navigator, Chapter 13:
      Interference effects are greater at the longer radar range scale settings. The interference effects can be distinguished easily from normal echoes because they do not appear in the same places on successive rotations of the antenna.
      Stacks, masts, samson posts, and other structures, may cause a reduction in the intensity of the radar beam beyond these obstructions, especially if they are close to the radar antenna.
  2. (nautical) A temporary or movable pillar or bollard, for various purposes.
  3. In deepwell boring, the post which supports the walking beam of the pumpjack.
    • 1911, “Petroleum”, in Encyclopædia Britannica, 11th edition, New York, N.Y.: Encyclopædia Britannica, Inc.:
      The whole derrick is set up by keys, no mortices or tenons being used, and thus the complete rig may be readily taken down and set up on a new site. The samson-post, which supports the walking beam, and the jack-posts, are dove-tailed and keyed into the sills. The samson-post is placed flush with one side of the main sill, the band-wheel jack-post being flush with the other side, so that the walking-beam, which imparts motion to the string of tools, works parallel with the main sill.
