Stainless Steel Flagpole Base for Rail Mount (14 mm)

This stainless steel flagpole base is designed to make flying a flag on your boat effortless and secure, without any complicated installations. Crafted from polished marine-grade stainless steel 316, it offers superior resistance to rust and corrosion, ensuring it remains in top condition despite constant exposure to saltwater and UV rays. The base attaches to your boat’s rail using an adjustable clamp that fits common rail diameters (~22–25 mm). You can quickly tighten it onto a railing (such as a stern pushpit or bow rail) with simple tools, avoiding any need to drill holes. Once clamped in place, the holder stays firmly fixed and will not slip or rotate, even under strain.

The socket of the base is sized to accommodate a flagpole up to 14 mm in diameter, covering most standard boat flags (whether it’s a national ensign, club burgees, or signal flags). The flagpole inserts easily into the base and is held upright securely, keeping your flag flying visible and untangled. The sturdy triangular base and strong clamp design add extra stability – your flag won’t wobble or tip, even in brisk winds or when cruising at speed.

The mirror-polished finish not only enhances the appearance (blending nicely with other deck hardware) but also provides a smooth surface for inserting or removing the flag staff. Installation is very straightforward: position the base on the desired rail location (commonly at the stern rail for an ensign), then tighten the clamp screws evenly – that’s it. No need to drill into your deck or transom, preserving your boat’s structure and allowing you to reposition the base freely if needed.

By using this base, you can fly your flags proudly and safely. It’s particularly useful for sailing yachts and motorboats where owners wish to display the national flag at the stern or a courtesy flag when visiting foreign ports. The base makes it simple to hoist or lower a courtesy flag on the rail, where it is clearly visible.

Usage Recommendations: For small to mid-sized boats (approximately 15–50 ft in length), this flagpole base offers a convenient solution. It’s ideal for mounting on cockpit rails, flybridge rails, or any standard tubing on deck. If you need to temporarily remove the flag staff (for instance, when trailering the boat or passing under low bridges), the clamp can be loosened quickly to detach the base or reposition it. This flexibility means you can adapt the flag placement as needed. With this stainless steel flagpole base, your boat is always ready to display a flag – a sign of identity and pride – held secure and fluttering freely for all to see.
