Lake Travis doesn’t have one bottom type — the main body and dam area are steep limestone rock, while many coves silt in with sand and clay depending on water level. That means “best anchor for Lake Travis” really has two right answers: a rock-gripping box, grapnel, or modern spade-style anchor for the rocky drop-offs, and a traditional fluke anchor for the softer coves. We’ve grouped real, verified products both ways instead of pretending one anchor covers the whole lake.

The picks, in detail
Slide Anchor Box Anchor (Fold and Hold)
The original folding box anchor, purpose-built to wedge into rock crevices and weed beds the way Lake Travis’s shoreline demands, then fold flat for deck storage on the ride home.
- Folding box design
- Sized for boats up to ~40 ft
- Stainless hardware
- Excellent holding on rock and weed bottoms
- Folds flat, doesn’t gouge gelcoat
- Bulkier to stow than a fluke anchor
Gen3 Marine Box Anchor
A lower-cost box-style anchor that gives up some of the Slide Anchor’s refinement for a price that makes sense on a pontoon or ski boat used mainly for swimming stops in rocky coves.
- Galvanized steel box design
- Folding for storage
- Budget-friendly entry into box anchors
- Still grips rock and weeds well
- Lighter-duty than the Slide Anchor original
DeckMate 23 lb Box Anchor
Marketed specifically at pontoon owners, this box anchor is sized and weighted for the flat-bottomed boats that make up a large share of Lake Travis’s rental and family-boat traffic.
- 23 lb galvanized steel
- Pontoon-specific sizing
- Purpose-built for pontoon anchoring
- Strong rock/weed holding
- Heavier than needed for smaller ski boats
Mantus M1 13 lb Galvanized
A modern spade-style anchor that resets quickly if it breaks free — useful on a lake where wind can swing a boat over a mixed rock-and-sand bottom in a single afternoon.
- Roll bar for reliable orientation
- Hollow-shank, high holding-power design
- 13 lb, suited to boats up to ~27 ft
- Sets fast and resets well after a wind shift
- Strong in mixed bottom types
- Pricier than a comparable box or fluke anchor
Manson Supreme 5 lb Galvanized
A compact modern anchor sized for smaller ski and wake boats — Manson’s roll-bar design sets reliably in the mixed rock/sand transition zones common around Travis’s coves.
- Roll bar design
- 5 lb, sized for smaller runabouts
- Sets quickly on first try
- Compact for smaller bow lockers
- Undersized for anything over ~20 ft
Rocna Original 4kg (8.8 lb) Galvanized
One of the anchors most often named by cruisers for rock and mixed bottoms; the roll-bar keeps the fluke oriented correctly on the first drop instead of skating over a rocky ledge.
- Roll bar orientation
- Concave fluke for high holding power
- 4kg size for boats up to ~30 ft
- Excellent reputation on rock and mixed bottoms
- Sets on the first try more often than older designs
- Most expensive anchor on this list at this size
Lewmar Delta 14 lb Galvanized
A self-launching plow anchor that’s been a mainstream all-rounder for decades — not the single best choice for pure rock, but a safe, versatile pick if you anchor in a mix of coves through the season.
- Self-launching plow shape
- 14 lb, suited to boats to ~35 ft
- Reliable all-around performance
- Widely available, easy to service
- Can struggle in the largest rock crevices where a box or grapnel excels
Attwood 3.5 lb Folding Grapnel
A cheap, compact backup anchor whose prongs hook directly into rock crevices near the dam — the classic “rock bottom” anchor, best paired with a trip line since it can wedge in tight.
- Folding four-prong design
- 3.5 lb, for boats 5-12 ft or as a secondary anchor
- Very inexpensive
- Hooks well into true rock crevices
- Can be hard to retrieve without a trip line if it wedges
Fortress Guardian G-5 (2.5 lb aluminum)
A lightweight fluke anchor for Lake Travis’s softer, silted-in coves — not a rock anchor, but a good secondary or bow anchor for the sandier stretches many boaters actually swim and beach at.
- Aircraft-grade aluminum, 2.5 lb
- Adjustable fluke angle
- Very light for its holding power in sand/mud
- Easy to hand-retrieve
- Poor holding on true rock — pair with a rock anchor, don’t rely on it alone
Danforth Standard S-1600 (25 lb)
The classic fluke anchor, best suited to Lake Travis’s sandier and silted coves rather than the rocky main body — a reasonable second anchor if most of your anchoring happens in the calmer bays.
- 25 lb, 1,600 lb rated holding power
- Twin-fluke design
- Excellent holding in sand and mud
- Well-known, easy to find parts for
- Not recommended for rock — avoid on the lake’s rockier stretches
Buying tips
- Lake Travis’s bottom changes with water level — a cove that’s soft silt when the lake is full can be exposed limestone shelf when it’s low. Carry a rock anchor even if you mostly anchor in coves.
- Add at least 6 feet of chain between rode and anchor; it helps any anchor lie flatter and set better on rock, and resists abrasion on the lake’s limestone ledges.
- Use 5:1 scope (5 feet of line per foot of depth) as a baseline, and more on the lake’s steeper drop-offs near the dam.
- If you use a grapnel or box anchor in true crevice rock, rig a trip line to the crown — it’s the difference between a quick retrieve and cutting your rode.
