1. Rod Length: A shorter rod is generally easier to handle in a kayak, as it allows you to fish in tighter spaces and make quicker, more precise casts. A rod that is 7 to 8 feet long is a good choice for kayak fishing.
2. Power: The power of a rod refers to its ability to handle different weights and sizes of fish. For kayak fishing, a medium to medium-heavy power rod is a good choice, as it will allow you to target a wide range of saltwater species without being too cumbersome to handle.
3. Action: The action of a rod refers to the amount of flex it has when pressure is applied. A fast action rod has less flex and is good for making longer, more accurate casts, while a slow action rod has more flex and is better for softer presentations.
4. Material: Rods can be made from a variety of materials, including fiberglass, graphite, and composite materials. Fiberglass rods are more durable and affordable, but they are also heavier and less sensitive than graphite or composite rods. Graphite and composite rods are lighter and more sensitive, but they are also more expensive and prone to breaking if not handled properly.

Some good options for kayak fishing rods include the Okuma Cedros CJ-65S, the Penn Battle II, and the G. Loomis E6X Spinning Rod.
