Boat & Dock Flag Poles — Rod Holder, Pontoon & Dock Mounts
A flag on the water takes more abuse than one on a house. Salt, spray and 40-knot apparent wind will destroy a flag rigged for a front porch — and a mount that isn't made for it will work loose or corrode through in a season.
Everything here is built for marine use: boat flag poles that drop into an existing rod holder, pontoon and dock mounts, and aluminum dock mounts for full-height 15' and 20' poles. Not sure what fits your boat or dock? Call 800-454-6998 — tell us the rod holder diameter or the dock post size and we'll match it.
Rod holder flag poles
The simplest way to fly a flag off a boat: a pole sized to drop straight into a rod holder you already have. Nothing to drill, nothing to mount, and it comes out in seconds when you want the holder back for fishing.
- Rod holder flag pole — the standard fit for most fishing rod holders. Our best-selling marine mount.
- Premium rod holder flag pole with swiveling mount — the flag rotates with the wind instead of wrapping the pole underway. Worth it if you run at speed with the flag up.
- Stainless steel clamp-on rod holder — adds a rod holder to a rail if you don't already have one.
Which size flag? On a boat, smaller is better. A 12x18" or 2x3 ft flag flies cleanly at speed; a 3x5 on a short pole will drag and flog itself apart. Save the big flag for the dock.
Dock & pontoon mounts
A dock flag pole is a permanent install and can carry a full-size flag — which makes it the one people actually see from the water.
- Aluminum dock mount — for 15' and 20' flagpoles. Bolts to a dock post or piling and carries a full-height pole with a proper flag. This is how you put a real flagpole on a boat dock.
- Pontoon mounts — rail-mounted holders for pontoon and deck boats.
Choosing a marine mount
| What you have | Use |
|---|---|
| Boat with rod holders | Rod holder flag pole |
| Boat run at speed with flag up | Premium swiveling rod holder pole |
| Rail but no rod holder | Stainless clamp-on rod holder |
| Pontoon or deck boat | Rail-mounted pontoon holder |
| Dock, pier or piling | Aluminum dock mount + 15' or 20' pole |
Flags for salt water
Nylon is the right cloth for marine use — it dries fast, sheds salt and flies in light air, where heavier polyester needs real wind to stand out. Rinse with fresh water when you rinse the boat and a flag lasts several seasons instead of one. Sewn stripes and embroidered stars outlast printed flags in constant wind.
Now you need something to fly. See nautical flags — ensigns, yacht club and officer flags, courtesy flags for foreign waters, and the full alphabet and numeral signal set in marine-grade nylon.
Bigger installations
For a yacht club, marina or waterfront property, a nautical flagpole is the proper answer — multi-mast marine systems with gaff and yardarm in 20 to 45 ft, so you can fly the ensign, club burgee and officer flags in correct position at once.
