BLUEWING 18in Upgraded Fishing Spreader Bar Port Canyon

The 18in Port Canyon spreader bar includes 6in floating squids and three types of trolling birds: center, port walker, and starboard walker. Upgraded construction addresses diving and flipping issues, with a stronger main line (crimps increased from 100 lbs to 160 lbs). Best for anglers who want a compact, versatile spread for multiple lines, including wahoo and marlin setups. A limitation is the 18in size; buyers targeting very long-distance spreads may prefer larger bars.
BLUEWING 18″ Upgraded Fishing Spreader Bar Port Walker Offshore

This 18″ spreader bar features 316 stainless steel rod and enhanced line strength, with a configuration including center birds, bulb squids, and big game lures. It’s well-suited for anglers who want a compact setup that still accommodates multiple lures. Best for lighter to mid-weight offshore settings. A potential drawback is that some long-range spreads may require larger bars for added distance.
BLUEWING 36″ Port Walker Offshore

The 36″ Port Walker Offshore bar provides extended reach with 6″ bulbs and 316 stainless steel rods. It includes a set of center birds and trolling lures, designed to attract big game fish. Best for anglers seeking greater spread and distance between lines. Limitations include size and weight, which may affect boat handling in rough seas or smaller vessels.
BLUEWING 36″ 316 Stainless Steel Spreader Bar Rod Heavy Duty

With a 36″ length and 316 stainless steel construction, this heavy-duty spreader bar is designed for continuous use under high pressure. It uses 3-Way swivel sleeves to prevent line twisting and comes with a 300-pound test main line for durability. Choose this if you need robust performance in demanding offshore situations. A caution is to verify compatibility with your boat’s rigging before purchase.
BLUEWING 36″ Upgraded Formation With 6″ Floating Squids

Formation spreader bar combines 6″ floating squids and 316 stainless steel rod for a bright, enticing presentation. This option is optimal for anglers who want a strong multi-lure spread with visible action to attract big offshore species. Best for vivid lure action and compatible with existing trolling rigs. A possible limitation is that multi-color lures may require more maintenance to keep lines clean and untangled.
Buying Guide
- Bar Length and Boat Size: Short bars (18 in) are easier to manage on smaller boats; longer bars (36 in) extend the lure spread but may affect handling on compact vessels. Choose based on boat length and handling capabilities.
- Material and Corrosion Resistance: 316 stainless steel offers superior saltwater corrosion resistance. For harsh marine environments, prioritize 316 stainless steel rods and swivels.
- Line Strength and Durability: Look for spreader bars with higher main-line breaking strength (e.g., 160 lbs min vs 100 lbs min). Strong crimps reduce line failure during heavy-tackle fishing.
- Lure Configuration: Center, port walker, and starboard walker birds enable multiple lure paths. If you want more lines per spread, choose models with diverse bird configurations.
- Weight and Handling: Heavier bars require more boat stability. For lighter vessels, consider 18 in options with robust construction rather than very long bars.
- Maintenance: After saltwater use, rinse with fresh water and inspect crimps and swivels to prevent corrosion and twisting.
- Best Use Scenarios: For big-game offshore trips targeting tuna, marlin, and wahoo, longer bars with multiple lures tend to improve bite opportunities. For multi-day trips, modular setups can be advantageous.
FAQ
- What is a trolling spreader bar? A spreader bar is a device that holds multiple lures in a spread behind a boat to maximize bite opportunities by presenting multiple attractants to fish.
- Which bar length should I choose? Choose 18 inches for smaller boats or beginners; choose 36 inches for longer distances and bigger spreads in open water.
- Are 316 stainless steel bars worth it? Yes, 316 stainless steel offers better corrosion resistance in saltwater and longer life in harsh marine environments.
- What should I inspect after fishing? Check crimps, swivels, and line for wear; wash the bar with fresh water to remove salt and debris.
- Can I mix brands in a single spread? Mixing is possible if each bar uses compatible line strength and lures, but standardizing helps prevent tangling and imbalance.
- Is a heavier bar better for big game? Heavier bars can handle stronger trolling lines and lures, but ensure your boat can safely manage the added weight and drag.
