The main body tube has a bore with an inside diameter just larger than the diameter of the support post. An adapter ring may be used within the bore of the main body tube for mounting on posts that are smaller, or not cylindrical. Support stub members radiate from the main body tube, and the attachment arms secure to these with quick release pins. The support arms may be used with fishing or boating accessories, beverage holders, or other equipment. ## Claims ### Claim 1 A marine hub comprising a generally round-profile hub body member having a vertically oriented central bore adapted to fit snugly onto a vertical generally cylindrical support post; means on said body member releasably gripping said support post to hold the body member securely in place thereon; a plurality of support stub members protruding generally radially and horizontally outward from said body member, with outer ends thereof which serve as a male or female socket member; a plurality of elongated attachment arms each having a female or male socket member formed at a radially inward end thereof and adapted for fit removably onto a respective one of said support stub members; said socket members of said attachment arms and said socket members of said support stub members each having at least one through bore configured such that the through bores align when the respective attachment arms are placed onto the associated support stub members; and at least one retaining pin adapted for penetrating aligned through bores of said support stub members and attachment arms to hold the attachment arms removably in place supported on said marine hub body member. ### Claim 2 (depends on 1) The marine hub of claim 1 wherein said support stub members are of square cross section and the socket members of said attachment arms are square tubular members. ### Claim 3 (depends on 1) The marine hub of claim 1 wherein said support stub members are of polygonal cross section and said socket members of said attachment arms are of round, octagonal, or hexagonal section. ### Claim 4 (depends on 1) The marine hub of claim 1 wherein said means for releasably gripping includes a split adapter ring fitting within the central bore of said body member. ### Claim 5 (depends on 1) The marine hub of claim 1 wherein said body member is in the form of a split tube having an axial gap therein with a pair of lugs affixed to said split tube on opposite sides of said gap, and including compressing means for drawing the lugs towards one another to compress the central bore against said support post. ### Claim 6 (depends on 5) The marine hub of claim 5 wherein said compressing means includes a cam action clamp having a pin passing through said lugs, and a lever-action cam disposed on one end of said pin. ### Claim 7 (depends on 5) The marine hub of claim 5 wherein said compressing means includes a hand screw having a threaded rod passing through an opening in one of said lugs and engaging a threaded bore in the other of said lugs. ### Claim 8 (depends on 1) The marine hub of claim 1 wherein there are three of said support stub members and three of said attachment arms, disposed on said body member at a nine-o'clock position, a twelve-o'clock position, and a three-o'clock position, respectively. ### Claim 9 (depends on 1) The marine hub of claim 1 further comprising an adapter ring fitted into the central bore of said body member, and having an outer diameter to match the inner diameter of said cental bore and an inner diameter to match the outer diameter of said cylindrical support post. ### Claim 10 (depends on 1) The marine hub of claim 1 wherein said at least one retaining pin includes a quick-release pin having a hand grip at one end, and a lanyard attached thereto. ### Claim 11 (depends on 1) The marine hub of claim 1 wherein said plurality of elongated attachment arms includes at least one extruded tubular member having a gap formed along one side and a keyway formed therein, and adapted for receiving keyway mounted accessories therein. ### Claim 12 (depends on 1) The marine hub of claim 1 wherein said body member is formed as two halves with an axial hinge connecting the two halves and a compressive clamp securing the two halves of the body member onto the support post. ### Claim 14 (depends on 1) The marine hub of claim 1 wherein said body member is formed of a pair of half-rings with a pair of bolts that threadably secure the two half-rings to one another, such that the half-rings are adapted to secure onto said support post.
