How to Find Ahi Before You Leave the Dock: My Pre-Fishing Intel System

How to Find Ahi Before You Leave the Dock: My Pre-Fishing Intel System

I tell people all the time: 80 percent of your fishing effort should happen before you ever leave the dock. Most guys focus on lures, hook setups, and spread positions. Those things matter, but if you are fishing the wrong stretch of ocean, none of it helps. The real work is done two to three days before you go.

Build Your Intel List Before the Trip

Two to three days out, I start calling around. I aim for six to eight people, and I log everything in my phone as I go. The list might look like this:

  • Jason: 10 miles, 30 degrees (three days ago)
  • JR: caught two, 12 miles at 34 degrees (yesterday)
  • Mark: got one, 19 miles at 70 degrees (yesterday)
  • Brent: caught at 12 miles, 40 degrees (yesterday)

Now I have two zones shaping up, and I know which information is fresh. Older reports show where fish were. Fresh reports show where they are now. I pick a primary zone based on the freshest intel and set a secondary zone from the older data. Before I even get to the harbor, the plan is already made.

One thing a lot of guys skip: note the time of day the bite happened. I take that time and go straight to a tide chart. Tides shift roughly one hour per day, so if the bite went at 7 AM today, it might go closer to 8 AM tomorrow. That is not a guarantee, but it narrows the window.

And call back even on the days you did not catch. If I went out and saw nothing, I call my guys and tell them. I worked 12 miles, 30 to 40 degrees, no birds, no marks, dead. That information has value. It helps them cross that zone off the list, and it builds the kind of trust that makes people pick up when you call.

The Miles-and-Degrees System

When people in my network give me a position, they use miles and degrees. Here is how it works. Every harbor I fish out of, I put a GPS waypoint on the head buoy. When I navigate back to Waianae Boat Harbor from wherever I am on the water, the GPS shows me the bearing and distance home. If it reads 30 degrees at 12 miles, that means I am 12 miles out on a 30-degree bearing from the head buoy. That number is exactly what I pass to my network.

JR caught at 12 miles, 34 degrees means 12 miles from the head buoy on a 34-degree bearing. Everybody using the same reference point makes the information accurate enough to actually fish. Some guys still describe spots by landmarks: outside Nanakuli on the thousand-fathom line. That works too, but miles and degrees is more precise and easier to log.

Moon Timing

I look at moon phases when I am trying to pick days. The general rule I follow: fish three to five days before the full moon or the dark moon, then again two to five days after. More moon around means more current, and more current generally means fish are feeding.

I also have a solar-lunar app on my phone that rates days from one fish (slow) to three fish (excellent). I take it with a grain of salt. The fish bite when they want to bite. I have had great days when the app said it would be dead, and I have had slow days when it said it would be excellent. Use it as a guideline. Do not let it be the reason you do not go.

Building Your Network from Zero

If you are just getting into offshore fishing, building a network is probably the hardest part of this whole process. Here is how I started.

The most direct path is to find someone who already knows what they are doing and ask to fish with them. I started fishing with my friend Brent after he asked me for over a year. I finally went, and through his crew I met other guys with boats. Those guys became part of my network. One of them was someone I played baseball with when we were younger. I ran into him at a tournament, found out he was a captain now, got his number, and he is one of my regular calls before a trip.

Fishing clubs are another way in. Most harbors on Oahu have one. You meet guys with the same interest, and over time that turns into a real information-sharing relationship.

A few things I hold to with my network: do not hold grudges when people do not call back right away. If a guy catches five ahi and you text him for information, he might be cleaning fish, dropping them at auction, getting the boat ready for the next day, and getting home to his family all at once. He is not hiding the bite from you. Give it time.

Do not have expectations when you share. If I give lures to someone and then they do not call me back after a good trip, I do not mark it against them. I just call again next time. If that pattern repeats over time, I figure out who is really part of my network and who is not. We are still friends. I just know who to call first.

What to Do When Both Zones Are Dead

Some days the fish do not bite. If I fish zone A and it looks genuinely dead, no birds, no marks, nobody hooked up, I move to zone B. If zone B looks the same, I do not run the shallow ledge looking for wahoo or ono just to put something in the box.

I stay in deep water until my time runs out, and then I come in. If you bail to the inside looking for ono, you might catch one and you might not. Either way, you have spent travel time and a shallow shot when you could have stayed in your ahi zone. Over time, that pattern costs you. Stay in the deep. Finish your day. Go home. Call your guys. Start building the list for next time.

No good fishing trip starts at the harbor. It starts two or three days earlier, on the phone. For more on staying in your zone once you get out there, read about how I mow the lawn to work a zone consistently.

How We Make Our Hawaiian Trolling Lures: From Scrap Lead to the Tuning Box

I walk you through how we build every lure at our shop in Hawaii, from the balanced lead insert and the star paper inlay to five passes of paint and the tuning box. It is the same process I showed on camera with the H-1 fish head and the 9 inch Ice Blue Moke Bullet.

Blunt Bullet Trolling Lures: Why We Shortened the Head and How I Skirt It

The blunt bullet is a shorter, fatter bullet head we designed to skitter along the surface. Here is when I run it, why I put two skirts on it instead of three, and the 7 inch skirt trick that squeezes more action out of it on a small boat.

Hook Placement for Trolling Lures: Why I Don't Try to Hide the Trailer Hook

September 23, 2026

I get asked all the time whether the trailer hook needs to hide inside the skirt. It does not, and there is a good reason: marlin swat the back of the lure first, and a hanging hook that flops at trolling speed looks like a fish tail. I also cover when to size up from 9/0 to 11/0 and 10/0 hooks based on skirt bulk.
