An Antal V-CAM rope clutch grips a line on three sides with a V-shaped cam, holding up to 600 kg on 6-10 mm line versus 500 kg for the flat-cam CAM 611 — MAURIPRO stocks both series, plus the larger V-CAM 814, so you can match the mechanism to your line's real load, not just its diameter.
If you've shopped Antal rope clutches, you've probably run into this: the CAM 611 and the V-CAM 611 sit side by side in the catalog, cost within a few dollars of each other, fit the same 6-10 mm line, and even look nearly identical from the outside. It's not obvious which one you actually need, or whether the "V" is worth paying for at all.
This guide is written for the cruiser (roughly 30-45 ft) replacing a tired clutch, adding a control line at the mast, or laying out a fresh cockpit and trying to decide between Antal's flat-cam CAM 611, the V-Grip-based V-CAM 611, and the larger V-CAM 814. The short version: the mechanism inside the housing is genuinely different, and it changes both the load rating and how gently the clutch treats your line.

What's actually different inside a CAM 611 versus a V-CAM clutch?
The CAM 611 uses what Antal calls a flat cam: a toothed cam presses straight down against a flat lower surface, pinching the rope between the two. It's a proven, simple mechanism, and it's why the CAM 611 has been Antal's entry-level clutch for years. The V-CAM series — V-CAM 611 and V-CAM 814 — replaces that flat cam with a V-shaped cam that closes against a curved lower surface, so the rope is gripped on three sides instead of two. The extra contact area is the whole point of the "V": more surface gripping the line means more holding power for the same line diameter, and the load is spread more evenly across the rope's cover instead of concentrated under one flat pad.
Does the V-CAM's extra grip translate into a higher working load?
It depends on exactly which line size you're comparing, and this is where it's worth reading the spec sheet rather than assuming "V" always means "stronger." Antal rates the CAM 611 with one blanket figure — 500 kg — that covers its entire 6-10 mm range. The V-CAM 611, by contrast, is rated separately at each line size it's sold for: 400 kg at 6 mm, and 600 kg at 8 mm. That means at the thin end of the range, the plain CAM 611's single 500 kg rating is actually higher than the 6 mm V-CAM 611's 400 kg figure — the V-CAM's advantage shows up most clearly on the 8 mm line, where it's rated 100 kg above the CAM 611's blanket number. Step up to the V-CAM 814 and the picture is unambiguous: 850-1,500 kg across 8-14 mm, well beyond anything the CAM 611 housing is built to hold.
Don't stop at line size when you're picking between these — check the working-load number for your specific diameter, not just whether the rope physically fits the cam.
Single or double — how do the CAM 611 and V-CAM 814 banks compare?
Both series are also built as double-clutch units — two complete cam mechanisms sharing one mounting base, not one mechanism splitting its load across two lines. A double CAM 611 keeps the full 500 kg rating per line, at 62 mm wide instead of 33 mm for the single; a double V-CAM 814 keeps its per-diameter rating (1,200 kg at 10-12 mm) per station, at 65 mm wide instead of 36 mm. If two control lines genuinely terminate at the same spot on deck — a cunningham next to a reef line, say — a double bank is usually a cleaner install than two single clutches mounted separately, and it doesn't cost you any working load per line to get there.
Which should I choose?
Choose the CAM 611 for light-duty control lines — cunninghams, outhauls, reefing lines — where 500 kg is comfortable margin and you don't need the V-CAM's extra grip. Choose the V-CAM 611 when you're running 8 mm line at a load that pushes past what the CAM 611's blanket rating comfortably covers, or when you want the gentler three-sided grip on a low-stretch or Dyneema-cored line that a flat cam can mark up over time. Step up to the V-CAM 814 for genoa sheets and halyards in the 8-14 mm, 850-1,500 kg window — the point where the 611-series housings simply aren't rated to go. For anything beyond 14 mm or 1,500 kg, MAURIPRO's Antal V-Grip guide covers the V-Grip 10 through V-Grip Plus range that picks up where the V-CAM 814 leaves off.
Expert notes
From our rigging bench: the CAM 611 and V-CAM 611 share the same external footprint — 119 x 33 x 73 mm, mounted on the same 2 x 6 mm screw pattern — so upgrading from one to the other on an existing boat doesn't mean redrilling the deck or cockpit coaming. It's a straight swap.
We also get asked whether the "Silver" name on some of these SKUs is a load rating or a finish — it's just the polished aluminum lever option. The mechanism and working load are identical to the standard black-lever version of the same model.
Common mistakes
- Assuming "V-CAM" always means a higher load than the equivalent CAM 611. At the smallest shared diameter, the CAM 611's blanket rating can actually be higher — check the number for your specific line size.
- Ordering a V-CAM 814 for a line under 8 mm. The 814 series starts at 8 mm; a thinner control line belongs on a CAM 611 or V-CAM 611 instead.
- Assuming a double clutch splits one line's rated load across two stations. It doesn't — each station in a double bank is a complete, independently rated clutch.
- Judging the clutch by line diameter alone. A thin, high-modulus line can outrun a small clutch's working load even though it fits the cam cleanly.
Frequently asked questions
What does "V-CAM" mean on an Antal rope clutch?
V-CAM refers to Antal's V-shaped cam mechanism, which closes against a curved lower surface to grip the rope on three sides instead of the two-sided pinch of the standard flat cam used in the CAM 611. It's the same "V-Grip" technology used in Antal's larger V-Grip clutches.
Is a V-CAM 611 stronger than a CAM 611?
Not automatically — it depends on the line size. The CAM 611 carries one 500 kg rating across its full 6-10 mm range, while the V-CAM 611 is rated separately per size: 400 kg at 6 mm and 600 kg at 8 mm. The V-CAM's advantage shows up clearly at 8 mm, not necessarily at 6 mm.
Can I swap a CAM 611 for a V-CAM 611 without re-drilling?
Yes for the base single models — both share the same 119 x 33 x 73 mm footprint and 2 x 6 mm screw pattern, so a V-CAM 611 mounts on the same holes as the CAM 611 it replaces.
What line sizes does the Antal V-CAM 814 cover?
8-14 mm across its single-station sizes, rated from 850 kg (8-10 mm) to 1,500 kg (12-14 mm) — it picks up where the 611 series tops out.
