TACO Marine Rigid Vinyl Flex-Core Rub Rail, 1.58 in x .635 in

Overview

The TACO Marine V21-9959 is a rigid vinyl Flex-Core rub rail for protecting the hull and deck joint on small to medium boats. The profile measures 1.58 in x .635 in and uses a rigid PVC outer cap with a lightweight high-density inner core, giving the rail the look and impact behavior of a traditional rigid vinyl rub rail while making it easier to handle during installation.

This rub rail can be cold formed around the gunwale and is drilled and countersunk for #10 screws on 8 in centers. It is a practical match for fishing boats, runabouts, bay boats, flats boats, ski boats, and similar hulls where a clean perimeter rail is needed for docking protection and a finished edge.

Key features

• Rigid vinyl Flex-Core construction with a rigid PVC cap and lightweight high-density inner core.
• 1.58 in x .635 in profile for boats up to 25 ft in length.
• Cold-forming behavior helps the rail follow the gunwale during installation.
• Continuous coil format reduces joints around the hull perimeter on longer installations.
• Drilled and countersunk for #10 screws on 8 in centers.
• Requires TACO Marine S11-4511 insert, sold separately.
• Made in the USA with a 5-year limited warranty.

Variants

This rub rail is offered in multiple configurations so the length and color can be matched to the boat and the scope of the job.

The variant differences are length and color. The profile, Flex-Core construction, screw spacing, and required S11-4511 insert remain the same across these listed configurations.

• V21-9959BKA20D: 20 ft length in Black. This shorter black rail suits replacement sections or smaller perimeter runs where the existing trim or hull detail calls for a dark finish.
• V21-9959WHC20D: 20 ft length in Frosty White. This shorter white rail works well for localized replacement or smaller boats with lighter gelcoat and trim.
• V21-9959WHC50D: 50 ft length in Frosty White. This longer white option helps reduce seams when covering more of the hull and deck joint in one run.
• V21-9959WHC60D: 60 ft length in Frosty White. This configuration gives extra coverage for longer perimeter runs while keeping the same profile and insert requirement.

Installation and fit

Before ordering, compare the 1.58 in x .635 in profile with the rail being replaced and confirm that the boat can accept the S11-4511 insert. The pre-drilled and countersunk holes help keep screw spacing consistent, but the mounting surface still needs to be checked for backing, old fastener locations, and a fair curve along the gunwale.

During installation, the Flex-Core structure helps the rail bend around typical boat contours without the handling difficulty of a fully rigid extrusion. For clean results, test-fit the rail around corners and transitions before final fastening, especially near the bow, transom corners, and any areas where hardware or navigation lights share the rub rail line.

Use cases on board

This rub rail is a good fit for owners restoring or replacing worn perimeter protection on trailer boats, center consoles, bay boats, flats boats, runabouts, and ski boats. It helps protect the hull edge during docking, raft-ups, and normal contact with pilings or fenders while giving the boat a finished rub rail line.
