Abstract: The rail mounted fishing pole holder is a specially designed device uniquely tailored to provide optimal support and convenience while using the inherent design of railing on most watercraft. A specially engineered mount is shaped to attach to an upper and a lower railing while also supporting a holder in an appropriately slanted position. Design specific clamps are structured to be adjustably affixed to said mount and enclose said railings. A cylindrical housing is incorporated with this demountable design to provide ease of use and economy of production.
