Portsmouth rig, Loop rig, Ian Golds rig, Golds'y rig etc, call it what you like. Initially developed on the south coast where Ian Golds had a major hand in its development, it allows you to clip multiple hooks yet still have a long hook length that fishes hard below the lead. Ideal for flatties or any fish that likes a bait nailed down and away from the lead. Also useful with semi buoyant baits or with floating beads holding the bait up for species like garfish and mackerel.

1. 50lb Daiwa Tournament rig body
2. 25lb black amnesia hook length
3. Size 2 Mustad 32602R's
4. Gemini lead clips
5. Aero beads (and crimps if they're your thing, I use stop knots)
6. Dropper swivels, a cascade swivel or a bait clip, I'll use a bait clip.
7. Silicon tube

Another flexible rig, you could fish a wishbone at the bottom or one hook clipped up and two hooks clipped down, like a clipped flapper. The options are endless. If I was tying this with a wishbone set up, I would use a Breakaway cascade swivel and clip the top hook to that. I'm not sure how well it fishes in tides with a strong flow, but it may well give you an advantage over slack water by carrying the bait well away from your main line and lead.

1. Tie the lead clip to the rig body.
2. Tie the hooks to the amnesia, you can make the bottom hook pretty much as long as you like within reason. Place a 1/2" long piece of silicon tubing on the long hook length then a 1" long piece of rig tubing on each hook length and finish with a dropper swivel on each hook length. Twist the 1" rig tubing onto the dropper swivel so it covers at least half of the barrel of the swivel, pic 2.
3. PRE-STRETCH THE HOOKLENGTH THOROUGHLY.
4. Slide a crimp (if you use them) and an aero bead onto the rig body, followed by the first hook length dropper. Another aero bead, crimp another crimp and aero bead, the second hook length dropper, the last aero bead and the final crimp.
5. Tie the leader clip (or swivel if you prefer) with all your components on the rig body in the right order as in pic 4.
6. Push a piece of wire into the silicone tubing and bend the top of the wire over so it makes a bait clip as in pic 5. Set the position of the bottom dropper swivel, around 3 or 4" above the lead. Place the bottom hook on the lead and then place the top hook on the clip. Now slide your stop knots up/down or crimp your crimps to set the top dropper. You should have an arrangement with the top hook clipped around 6" above the bottom one.

Because both of the baits are fairly tight behind the lead it casts pretty well. Obviously there'll be some drag from the hanging loop of line but its negligible, to be honest if you find that it's making a difference there are some more fundamental issues at stake. The flat, clear seas of the summer are not many tides away now, give it a try and let me know how you get on with it.
