Quick Verdict
If you need one holder that clamps onto an existing rail and leaves no screw holes, the 1 Pack Fishing Rod Holder with Enlarge Clamp is the straightforward buy at USD 29.79. If you need a fixed rack for four rods and prefer a wider tube with a corrosion-resistant aluminum build, the Silver Marine Aluminum 4 Rod Rack at USD 34.75 is the better match.

Where Each Product Wins
Go with the clamp-style holder when you want a tool-free mount, a smaller footprint, and a lower listed price. It grips rather than drills, which makes it easy to move between mounting points. Choose the 4-rod aluminum rack when rod capacity matters more, when you need a wider tube opening, and when a permanent screw-on mount on a wall or bulkhead is acceptable.
Product Notes
1 Pack Fishing Rod Holders for Boat, Fishing Rod Holder with Enlarge Clamp

The clamp is the main reason to choose this holder. It is built to work on round tubes, square tubes, flat surfaces, and some irregular shapes, with an expandable clamp range of 0.59 to 3.94 inches. The double V-shaped thread and anti-slip silicone pad form four contact points, so the holder can stay stable without scratching the boat. If you only need to secure one rod and you want to avoid drilling into your boat, this compact holder is a strong fit. The trade-off is capacity: this is a single-rod clamp holder, not a multi-rod rack. And because the clamp range has a 0.59-inch minimum, narrow rails below that width won't work.
Silver Marine Fishing Rod Holder Aluminum 4 Rod Rack Boat Rod Holder Wider Tube

This rack solves the opposite problem: it holds four rods in a wider tube design, which makes it easier to slide rods in and out. The marine-grade aluminum is said to be lighter than stainless steel while still resisting corrosion and harsh weather, and the PVC inner sleeves provide a scratch-resistant layer. The pre-drilled holes and included stainless steel screw kit make it a straightforward wall-mount option for boats, yachts, RVs, or camper walls. Choose it when you want a tidy, dedicated storage spot for multiple rods. The catch is that it is a screw-on rack, so it won't work as a no-drill clamp on a railing, and it costs more than the single clamp holder.
Final Choice by Use Case
For a quick, adjustable, one-rod setup on an existing rail, pick the Fishing Rod Holder with Enlarge Clamp. For a permanent, wider four-rod rack on a wall or bulkhead, pick the Silver Marine Aluminum 4 Rod Rack.
