A pair of bunk board guide-on post assemblies 30, 31 are mounted on opposite sides of the frame 20 of a boat trailer 4 just at the aft ends of the bunk boards 25, 26 of the trailer. The guide-on post assemblies each include a rectilinear upwardly extending support bar 38 that defines a longitudinal slot 50, and a buoyant guide-on post 44 is telescopically mounted downwardly about the support bar 38 and defines a laterally extending connector opening 52 that registers with the longitudinal slot. A connector pin 54 extends through the laterally extending connector opening of the guide-on post and through the longitudinal slot of the upwardly extending support bar so that the buoyancy of the guide-on posts telescopes upwardly in response to partial immersion of the bunk boards of the boat trailer, providing a visual indication of the location of the submerged ends of the bunk boards. |
