You’ve got a great offshore/nearshore contour map here, and the money spots are where structure, current, and bait stack together. 🎣
Best places to start
-
The point and contour pinch near the route marker
- That long black route line crosses a tight contour edge and a channel-like funnel. Those are classic ambush zones.
- Fish the up-current side and the first break line off the point.
-
The reef/structure area around the small islands
- The cluster around Pulau Makar / Pulau Upanjang has multiple edges, humps, and little cuts.
- Work the upwind side and any drop from 20 to 50+. Predators love sitting where bait gets forced past them.
-
The bay mouth near Teluk Tapanuli / Sibolga
- Bay mouths concentrate bait, especially when tide or current moves through the entrance.
- Fish the tips, corners, and deeper outside edge first, then fan out if the bait is there.
What I’d do first
- Start on the 45–60 ft contour break outside the islands and bay mouth.
- Then move to the steeper edge where the bottom falls fastest into deeper water.
- If you see birds, bait balls, or sonar marks, stay put — that’s the buffet line.
Best tactics
- Cast/jig the edges: Use a jig, metal spoon, or soft plastic and let it fall along the slope.
- Drift with the current: Keep your presentation moving naturally across the break.
- Work from shallow to deep: Fish the top of the structure first, then the drop-off.
- Look for current seams: Even light flow can pin bait on one side of a point.
Quick read on this map
- The most promising feature is not open water — it’s the intersection of contour change + structure + moving water.
- If you only had one shot, I’d pick the outer reef/point system off the island cluster before random open-water casting.
If you want the highest odds
Go when the tide/current is moving, and hit the spot during early morning or late afternoon. Those are usually the snack times for the fish kingdom. 😄
