Are you tired of bent guides, cracked ceramic liners, or the dreaded “tip wrap” when fishing with braid in a choppy sea? Here at Gerry’s Fishing, we’ve seen it all, and that’s why the Penn Squadron IV Inner Boat is one of our top recommendations for the serious boat angler. By running the line through the center of the blank, Penn has eliminated the weakest point of a traditional rod, creating a tool that is virtually bulletproof and incredibly smooth to fish with.
The “Inner” (or Inline) design is a revolutionary approach to heavy-duty boat fishing. Without external guides to catch on the gunwales of a crowded charter boat or get crushed in a rod tube during travel, the Squadron IV Inner is built for maximum durability. Because the line stays in direct contact with the internal wall of the blank along its entire length, the pressure of a fighting fish is distributed perfectly. This results in a flawless, “true” curve that maximizes the rod’s lifting power while providing a level of sensitivity that traditional guided rods simply can’t match.
At 7ft with a 30-50lb rating, this rod is a true powerhouse. It features a fast action that gives you a sensitive enough tip to feel the “knocks” of a cod or ling in 200ft of water, backed up by an ultra-strong 24T carbon backbone. Whether you are winching a big conger out of a wreck or jigging for halibut in a Norwegian fjord, this rod provides a tangle-free, high-performance experience.
Prime Locations & Uses:
Norway & Iceland: The ultimate “travel-proof” rod for targeting big cod, ling, and halibut. No guides means no damage in the holdall!
Deep Water Wrecking: Ideal for the English Channel or the Irish Sea when targeting large conger eels, ling, and specimen cod.
Heavy Tide Bait Fishing: The 30-50lb rating handles heavy leads (1lb+) with ease, keeping you in the “zone” even in strong currents.
Charter Boat Sessions: The lack of guides makes it much easier to manage in tight spaces and completely eliminates the risk of line wraps at the tip.
“The most common question we get is: ‘How do I get the line through?’ Every Penn Inner rod comes with a specialized threading wire—don’t lose it! My advice is to keep that wire taped inside your rod tube or tackle box. Also, because there are no guides to create friction points, this rod is a dream for braid users. You’ll notice much less ‘chatter’ through the blank when winching up big fish, giving you a much more direct connection to your catch.”

Q: Does the line get stuck or “clogged” inside the rod?
A: Not if you maintain it correctly! The internal surface is incredibly smooth. After a trip, we recommend running fresh water through the tip to flush out any salt or grit. If you do that, the line will continue to fly through the blank as smoothly as the day you bought it.
Q: Can I use a fixed-spool reel with this rod?
A: No. Like most inline boat rods, the Squadron IV Inner is designed specifically for multiplier reels. The entry guide (where the line enters the blank) is positioned to work perfectly with the line coming off a conventional reel spool.
Q: What happens if I lose the threading wire?
A: Don’t panic! While the Penn wire is the best tool for the job, in an emergency, you can use a long length of heavy-duty monofilament (80lb+) doubled over to push through the blank and pull your mainline through. However, we always stock spares here at Gerry’s if you need the real deal!
