  • the first member 30 of the housing 22 is circular and has a plurality of six evenly spaced holes 38 about the periphery thereof for securing the first member 30 to the wall 12 of the boat by the bolts 40.
  • the holes 38 are evenly spaced about the periphery of the first member 30 so that once six evenly spaced holes are drilled or otherwise formed in the wall 12 of the boat, the first first member 30 may be rotated and secured to the wall 12 of the boat in any one of various different positions.
  • the second member 32 is also circular.
  • a of bolts 36 I are disposed about the periphery of the second member 32 and extend therethrough and through the first member 30 for securing the members 30 and 32 together.
  • the bolts 36 may be removed to allow the members 30 and 32 to be disconnected whereby the ball 26 may be removed from the pocket if necessary.
  • the periphery of the first member 30 through which the bolts 40 extend is disposed in a first plane whereas the periphery of the second member 32 through which the bolts 36 extend is disposed in a second plane which is disposed at an acute angle relative to the plane of the periphery of the first member 30.
  • the central portion 42 of the first member 30 I is offset from the periphery thereof and is disposed parallel to the plane of the periphery of the second member 32.
  • the central portion 42 of the first member 30 is offset from the periphery of the first member 30 in opposite directions at opposite sides thereof.
  • the housing 22 is made of metal such as steel and has a coating of plastic such as nylon thereover or at least over the spherical surface 34 which defines the pocket.
  • the ball 26 presents a convex spherical surface which is in sealing and slidable engagement with the concave spherical surface 34 of the pocket defined by the housing 22.
