What the engine still flags
The solver searched every hook, line, leader, sinker, float, bait, rod and reel combination it could reach and found none that clears this. We print it rather than hide it.
Offshore Bluewater cannot be fished from shorevessel
Access here is offshore, boat. Either add a vessel to the build or pick a venue you can reach from the bank: the rest of this rig is otherwise unfishable.
Circle hook: do not set the hookhook
Reel down until the line comes tight and let the rod load. A circle hook slides to the jaw hinge and rotates closed on its own. A conventional swing pulls it straight back out of the mouth: the technique change is mandatory, not stylistic. Read the guide.
No sun protection selectedapparel
Offshore Bluewater runs up to 92°F and reflected UV off water roughly doubles your exposure. A UPF hoodie and polarized glasses are the two highest-value pieces of clothing in fishing, and the glasses also let you see structure.
Why these numbers
- Offshore Bluewater runs 60–600 ft and King Mackerel feeds at a depth bias of 0.40 (0 is the surface, 1 is hard bottom), so the engine puts the fish near 276 ft.
- Current rates 0.65, which the engine turns into roughly 1.95 oz to hold bottom and warns under half that. This build carries 1 oz.
- The water is gin-clear and King Mackerel rates 0.30 for line shyness and 1.00 for abrasion. Teeth decide this one: the leader is wire.
- Typical fish run 8–40 lb. That sets the 15 lb drag floor (this reel makes 25 lb) and the hook strength floor of 48 lb (this hook is rated 70 lb).
- Offshore Bluewater is salt water. Every hook, reel, rod and swivel in the build is checked for a salt rating, and all of them pass.

Eagle Claw Lazer Sharp Circle Sea
The cheapest way to fish circle hooks correctly. Corner-of-the-mouth hookups, minimal gut-hooking, and priced so you re-tie without flinching.
Bullet Weights Lead Bullet Worm Weights
The Texas rig weight. Slides on the line ahead of the hook, noses through cover, and costs almost nothing when you break one off.

American Fishing Wire Surflon Micro Supreme Wire
Nylon-coated 7-strand stainless. Supple enough to knot with a uni, tough enough that pike and mackerel teeth do not touch it.
Verified destination: Surflon Micro Supreme 90 lb, 5 m (2026-10-21).
Stren Original Copolymer
A blend that splits the difference: less stretch than straight mono, more manageable than fluoro, and cheap enough to respool often.
No exact product destination has been verified for this item.
Penn Battle IV Spinning Reel
A full-metal, sealed-drag saltwater workhorse. Heavier than a freshwater reel because it is built to be dunked, sanded, and used again tomorrow.
Verified destination: Battle IV / size 5000 (2026-10-20). Other sizes or packs are not verified by this link.
Penn Prevail III Surf Rod
Ten feet of graphite composite built to throw four ounces of lead and bait over the breakers and then stand in a sand spike all night.
Verified destination: Prevail III 10' Medium-heavy 2 pc (2026-10-21). Other sizes or packs are not verified by this link.
Scope: the solver builds a tied hook-and-line rig from the parts in our catalog, cheapest first among builds with the fewest problems. Hard baits with their own trebles, flies, and field gear (waders, clothing, boats) are left to you. A different catalog would give a different answer, and the studio will check whatever you swap in.
