The W Formation — Bird Bar Tactics to Match Sand Eels in Cold Water
Came to cast to feeds at Crab Ledge. The feeds dispersed. So the directional bars went out, the classic bars went inside the wash, the lines staggered to different depths, and olive beat pink every time. This is the spread deployment tutorial.
Crab Ledge, east of Chatham. The feeds had dispersed and the casting plan was off the table. Four bird bars, directionals outside the wash, classics inside, all olive — and couldn’t keep the bars out more than a couple minutes before getting hit.
The original game plan was casting to tuna keying on sand eels at Crab Ledge. There were good feeds earlier. The tuna were still there — but the feeds weren’t as epic as they had been. Scattered, dispersed, not castable. Plan B: light-tackle trolling with the bird bar spread. And once the bars went out, it became clear what color these fish wanted. Olive. Every time. Not pink, not green — olive, because the fish were keyed tight on sand eels and they wanted the imitator, not the attractor.
This episode is the spread deployment tutorial. Port vs. starboard bar placement, directional vs. classic bar logic, inside vs. outside the wash, staggered line lengths, the surge-and-drop tease on the classics, and the short-crew technique of letting a floating bird bar fish itself while you fight another fish. Every element of building and running a four-bar spread, on camera, with context.
East of Chatham on sand eels — know your forage before you load the spread
Context that shapes every decision that follows.
East of Chatham in summer is sand eel country. When tuna are working that water, there’s a roughly 75% chance the forage is sand eels. Mike said it directly: “75% of the time when I come out here, sand eels are the tuna forage.” That historical read doesn’t change the plan for the day, but it immediately tells you the color starting point — load the spread with imitator colors and have attractor colors as a secondary option. Don’t start with pink when the fish are almost certainly on sand eels.
- Sand eels are the baseline forage assumption east of Chatham. Load olive and natural colors first, attractor colors second. The historical read saves you the attractor-to-imitator correction mid-session.
- When casting feeds disperse, the spread doesn’t have to replace them immediately — the fish are still in the area. They’ve just gone subsurface or scattered. The spread finds them when the feeds aren’t showing.
- Crab Ledge holds tuna on contour lines (S400). The fish use depth bands to stage. The tactical troll series covers those contour lines effectively when fish aren’t showing on the surface.
- Tuna are attracted to the boat. Mike’s theory: the wash and the boat hull moving through the water simulates a whale or a fish discarding bait. That attractor effect is why the W formation works — fish come in on the boat and find bars at every entry point.
- Sand eel forage means tighter, more specific color matching. On a general bait day you can run attractors and imitators mixed. On a tight sand eel key, it’s all olive by the end of the morning.
Feeds dispersed — the Plan B trigger
The conditions that moved the session from casting to trolling.
Good feeds earlier in the session confirmed tuna were on the grounds. But by the time lines went in, the feeds had scattered — still fish in the area, still bait, but not the castable concentrations from earlier. This is the Plan B trigger: fish confirmed present, original approach no longer viable. Switch to the spread and cover water rather than waiting for a feed that may or may not reform.
The name of the game on a day like this is staying maneuverable. Keep the spread close to the boat, lines relatively short, ability to spin the boat quickly on a sonar mark or a surface boil. Longer spreads with outriggers sacrifice maneuverability. The short no-outrigger setup with directional bars is the tactical choice precisely because it stays responsive.
“The name of the game today is to remain maneuverable and really have a tactical trolling pattern. Most of these bars are quite close to the boat. Stay agile.”
Olive beats pink — reading the color key in real time
Four layers. Each one narrows the answer further.
“We started half attractors, half imitators. By the end of the morning it was all olive colored spreader bars — and that was the ticket. When they’re keyed in, when there’s a lot of bait like there is today, the natural colors really did the trick.”
Sand eels confirmed as the primary forage from the earlier casting session. Fish keyed tight on them — tight enough that attractor colors underperformed throughout the session. The historical read (75% sand eel probability east of Chatham) was confirmed by the in-session color data. Sand eel forage confirmed = imitator colors. Olive from the start would have been the correct call. Starting half/half was the diagnostic approach — the fish voted for olive within the first few bars. By the end it was all olive, all the time.
Fish came in on the olive color bar specifically — both the inside and the outside bar positions produced fish. The inside bar caught a fish that had swum into the wash, then the outside bar caught a fish that veered away from the wash. The spread geometry was validated: fish entering from different angles found different bars. Inside + outside bar both produced = the spread geometry is working. Fish approach from multiple angles and the W formation has coverage for all of them. The staggered lengths mean there’s something at every depth in the spread.
S400 Contour Lines — Crab Ledge. Depth contours hold bait and fish along the edge. The tactical troll series covers contour lines by running parallel to the edge and working the depth transitions. Fish stage on the contour, the boat working the edge brings the spread through their holding zone repeatedly. Contour structure = run parallel to the depth edge. The tactical troll covers the productive depth band. Work the contour, not just open water. Fish holding on the edge will see the spread on each pass.
Side scan confirmed fish in the area even when surface activity was absent. “There’s literally fish on this side scan.” One fish appeared on the side scan just before a strike, confirming the spread was working productive water. Fish marks on the side scan = keep running that track. Side scan marks = stay on that track. When the side scan shows fish in the spread zone, the next hit is coming. Don’t turn off a productive piece of water because the surface is quiet.
Tactical troll along the contour — maneuverable, close, responsive
OA800 Tactical Troll Series — short spread, lines close to the boat, ready to spin on a mark.
The tactical approach at Crab Ledge is different from the grid-and-surge pattern at The Dump. Here the structure is known — Crab Ledge is a specific contour. The troll works the edge of the contour, running parallel to the depth transitions where fish are staging. Lines stay close to the boat for maximum maneuverability. When a fish shows on the side scan or a boil appears, the boat can spin quickly without a long spread tangling.
Approach — step by step
OA800 Tactical Troll Series — work the contour edge, lines close to the boat for maneuverability. Spin quickly on side scan marks and surface boils. Short spread, high responsiveness.
Building the spread — port vs. starboard, directional vs. classic, olive vs. pink
Every decision in the spread deployment explained on camera.
The color decision — attractor vs. imitator
There are two categories of color in a bird bar spread: attractors (bright colors — pink, fluorescent green) and imitators (natural colors — olive, white, sand eel imitations). On a general bait day with no specific forage key, run a mix. On a tight bait key, run imitators. The session at Crab Ledge started half/half and ended all olive.
“There’s two types of colors when it comes to lures: attractors and imitators. Attractors are your bright colors — your pinks, your fluorescent greens. Imitators are specifically imitating something. Today the fish were really keyed in on sand eels. I always load up on all olive colored spreader bars. We started half attractors, half imitators — and by the end of the morning it was all olive colored spreader bars, and that was the ticket.”
Outfit
The decision at a glance
Step 1 loaded the historical read: east of Chatham means sand eels 75% of the time — start with imitators, have attractors on deck. Step 2 confirmed the Plan B trigger: feeds dispersed, fish still present, switch to tactical troll and stay maneuverable. Step 3 delivered the unlock in real time: both hookups on olive, attractor colors sitting untouched. Sand eel key confirmed. By the end of the morning it was all olive, all four bars. Step 4 built the spread approach: directionals outside the wash, classics inside, lines short for maximum maneuverability on the contour edge, surge tease on the classics. Step 5 closed with the deployment details: port is pink, starboard is green, the W formation covers every entry point, the mono top shot absorbs the shock, and the two-speed reel makes the fight manageable for any crew. The fish couldn’t keep away from the olive bars. Couldn’t keep the bars out more than a couple minutes before getting hit.
