Accessory mount extension arm

Abstract

A mounting structure has characteristics, properties, or features that provide stability for the accessories mounted or supported in relation thereto. The mounting structure may be in the form of a rigid or a semi-rigid composition, which may be formed at least in part by, or sufficiently covered or coated with, a material having a damping capacity, or an ability to isolate an accessory for a vessel, a slotted track supported in relation to the vessel, or a mounting arrangement supported in relation to the vessel or the slotted track. The mounting structure may be in the form of an extension arm for offsetting the accessory laterally, crosswise or transversely in relation to the vessel, slotted track, or mounting arrangement. The extension arm may include, or carry, a surface, that is configured to interlock with a surface of a mating structure, namely, a mounting arrangement and/or an accessory or accessory mount. The surface may be in the form of a ratcheting surface comprising radially extending protrusions or recesses that cooperate with mating radially extending recesses or protrusions supported by the surface of the mating structure. The mating surfaces interlock to prohibit movement of one surface in relation to another, for example, to hold the mounting structure in fixed relation to the mounting arrangement and/or the accessory, or the accessory mount.
