Aquawave Cu Sith 80F: A Small Floating S-Swimmer for Shallow Seabass
minagiman
Aquawave has added a small floating S-shaped swimmer to its seabass lineup: the Cu Sith 80F. At 80 mm and 14 g it is built for the shallow, slow-current water where seabass pick off small mullet and gobies — estuary flats, harbour light lines and little river seams. This is my rundown of what it does, where it fits and how I would rig it.
Cu Sith 80F specs
| Item | Detail |
|---|---|
| Length | 80 mm |
| Weight | 14 g |
| Type | Floating, S-shaped swimmer (slalom action) |
| Maker | Aquawave (Japan) |
| Colours | 8 |
What the lure does
The idea behind the Cu Sith is simple: a floater that slaloms in an S pattern instead of just wobbling. How it behaves depends on how you work it:
- Slow retrieve: a tight, narrow S-slalom just under the surface — the default action for calm shallows.
- Faster retrieve or in current: the S-slide gets wider and more erratic, which helps in flowing water.
- Twitch: the body can flip close to 180°, a sudden turn that triggers following fish.
- Faster still: it starts to skate and leaves S-shaped ripples on the surface — useful at night when fish are looking up.
Where it fits
- Estuary and tidal-flat shallows when small mullet (boras) are the bait
- Harbour light-and-shadow lines at night
- Small river seams and slow current edges
- Any spot too shallow for a standard 12–13 cm minnow
Tuning with weight stickers
Because it is a floater, you can add lead tape or weight stickers to make it suspend or sink slowly. That turns one lure into a near-surface swimmer and a slightly deeper slow-sinker, depending on the tide.
How it compares
| Lure | Size | Main action | Best use |
|---|---|---|---|
| Aquawave Cu Sith 80F | 80 mm / 14 g | S-slalom, turns, skating | Small-bait shallows, light lines |
| Shimano Monica 100F | 100 mm | Rolling shallow runner | Shallow flats, slightly bigger bait |
| Counter Wake 80F type wakebaits | 80 mm | Surface wake | Pure surface at night |
If you already carry a shallow roller like the Monica, the Cu Sith adds a different movement — the S-line and sudden turns — rather than duplicating it.

Suggested tackle
| Part | Recommendation |
|---|---|
| Rod | 8–9 ft seabass rod whose lower lure rating goes down to about 7 g |
| Line | PE 0.8–1.0 |
| Leader | 16–20 lb fluorocarbon |
| Snap | Small snap so the S-action is not restricted |
Things to keep in mind
- It is not a deep lure — skip it when fish sit low in the water column.
- At 80 mm it is small; when the bait is big konoshiro or large mullet, use something bigger.
- The S-action is sensitive to slack line and heavy snaps. Keep the line slightly tight and the terminal tackle light.
Minagiman’s take
A small, light S-swimmer is the kind of lure that saves a tough evening on the flats when seabass ignore regular minnows. I would keep the Cu Sith 80F in the box for small-bait situations and calm, shallow water.
