Ultimate Whips include cast aluminum rocker base with cushionner & set screw to compensate for most tidal fluctuations. The solid fiberglass rod is manufactured in multi-stages with an exclusive cross-wound fiberglass for extra rigidity unobtainable with solid rod alone. This multi-stage manufacturing gives these whips the necessary strength and flex to retain the boats’ position. Exclusive “Plug & Socket” design for quick and easy separation. Each whip includes our unique functional roller tip and a tie-off cleat for easier access to your boat. Stainless steel mounting hardware included.
