A sea anchor is deployed from the bow to hold your boat’s head into oncoming waves and stop drift in a storm; a drogue is towed from the stern to slow the boat and reduce broaching risk when running before heavy weather. MAURIPRO carries Lalizas sea anchors up to 45 ft, plus a heavier Professional series for larger offshore yachts. This guide explains what each device actually does, how they differ, and how to size one to your boat and storm plan.
If you sail a mid-size cruiser in the 30–45 ft range and venture beyond protected coastal waters, a sea anchor or drogue is cheap insurance against the two worst storm outcomes: being rolled beam-on to breaking seas, or broaching while running downwind. Neither device replaces good seamanship, but both give you a way to hold position or control your boat’s attitude when sail alone can’t.
This guide covers the Lalizas sea anchors MAURIPRO stocks — a Standard series up to 45 ft and a heavier Professional series for larger craft — and how to decide which role, bow or stern, fits your situation.

What is a sea anchor, and how does it work?
A sea anchor is a parachute-shaped drag device deployed from the bow on a bridle, set to hold your boat’s head into the wind and waves and sharply reduce your rate of drift. It doesn’t stop the boat outright — it lets the boat lie to the device while the device itself creates enough resistance in the water to keep the bow pointed into oncoming seas, which is the core of the classic “heave-to and ride it out” storm tactic.
MAURIPRO’s Lalizas sea anchors are built for exactly this: PVC-coated fabric with continuous internal webbing for strength, a weighted bottom and automatic opening so the cone sets itself once it’s in the water, and a harness buoy included so you can see and recover it. Lalizas markets the same design for use as either a sea anchor or a sea brake, and rates it for power boats, sailboats, inflatables, jet skis, and kayaks — the mechanism doesn’t change, only where you rig it.
What is a drogue, and how is it different from a sea anchor?
A drogue is towed from the stern instead of the bow. Where a sea anchor stops the boat and holds the bow into the seas, a drogue is meant to slow the boat down while it’s still moving — typically when you’re running before a storm and need to keep enough control to avoid broaching (turning broadside to a breaking wave, which is how boats get knocked down or rolled). A specialized version, the series drogue, strings many small cones along one long line to spread that drag evenly astern; it’s a well-known heavy-weather design among offshore sailors specifically because it resists the surging and yawing a single large drogue can still allow.
Lalizas doesn’t sell its sea anchors and drogues as two separate product lines — the same cone-and-bridle device is rated for use as “sea brake or sea anchor,” and MAURIPRO’s Professional series is labeled on its own packaging as a “Professional Drogue.” In practice, the device you rig off the bow to hold position is the same one you can rig off the stern, sized down, to add drag on a smaller boat.
How do you size a sea anchor or drogue to your boat?
Start with your boat’s length, then check it against the size the specific unit is built for — an undersized sea anchor won’t generate enough drag to hold your bow into the seas, and an oversized one creates shock loads your bow fittings and rode may not be built to absorb. MAURIPRO’s Lalizas Standard series is sized in five steps from 15 ft up to 45 ft (LAL-10071 through LAL-10075), and the Professional series steps up from dinghies and small fishing boats (No. 1) through medium boats and yachts (No. 2) to large vessels and commercial craft (No. 3).
If your boat’s displacement is heavy for its length — a full-keel cruiser versus a light coastal daysailer of the same length, for example — size up within the range rather than choosing strictly by length alone; the extra material has more work to do holding a heavier hull steady.
When should you deploy a sea anchor vs. a drogue?
Deploy a sea anchor from the bow when you want to stop and hold position — heaving-to in a building storm, riding out a blow at sea without making way, or slowing your drift toward a lee shore. Deploy a drogue from the stern when you’re already running before the storm and need to keep boat speed low enough, and steering control high enough, to avoid broaching on a following sea. The two tactics aren’t interchangeable: a device rigged off the bow to stop the boat is doing a different job than one towed astern to control a boat that’s still moving.
Which tactic you choose depends on sea room, your boat’s handling under bare poles, and the storm you’re in — this guide covers the gear, not a substitute for a storm-tactics plan practiced ahead of time.
Which should I choose?
For most mid-size cruisers doing coastal and near-offshore sailing, a Standard-series Lalizas sea anchor sized to your boat’s length (LAL-10074 for 30 ft boats, LAL-10075 for up to 45 ft) covers the bow-deployed, heave-to role at a price that makes it easy to carry as standing safety gear. If you’re planning sustained offshore passages where the unit may see real, repeated heavy-weather use, step up to the Professional series (LAL-10241 for medium boats and yachts) for the more robust build. Either way, keep the unit rigged with a bridle and swivel to a strong bow point, not a single cleat, and know before you need it whether you’re setting it up to hold your bow into the seas or to trail astern and control your speed running off.
Expert notes from the MAURIPRO safety locker
When cruisers ask us about storm gear for a first offshore passage, we point out that a sea anchor is one of the least-used pieces of safety gear aboard — and also one you most need to have already rigged and understood before the weather turns, because a pitching foredeck in 35 knots is not when you want to learn the bridle setup.
We also remind sailors that “sea anchor” and “boat anchor” are two different pieces of gear with a confusingly similar name — a sea anchor never touches the bottom. For ground-tackle anchoring in a harbor, see MAURIPRO’s anchoring equipment guide instead.
Common mistakes to avoid
- Rigging to a single cleat instead of a bridle. A sea anchor or drogue under load in a storm puts sudden, repeated shock loads through its rode — spread that load across a proper bridle to a strong bow point (or stern points for a drogue), not one fitting.
- Choosing by boat length alone and ignoring displacement. A heavy, full-keel 38-footer needs more holding power than a light 38-foot daysailer; size toward the upper end of the range for a heavier boat.
- Never having deployed and retrieved it before the storm. Practice setting up the bridle and retrieval line in calm conditions so the process is familiar under pressure.
- Confusing a sea anchor with a boat (ground-tackle) anchor. A sea anchor does not hold the bottom — it only creates drag in open water. Don’t rely on one where you actually need to anchor to the seabed.
Frequently asked questions
What’s the difference between a sea anchor and a drogue?
A sea anchor is deployed from the bow to stop the boat and hold its head into the wind and seas. A drogue is towed from the stern to slow a boat that’s still moving and help prevent broaching when running before a storm. Both work by creating drag in the water; the difference is where they’re rigged and what job they do.
Is a sea anchor the same as a boat anchor?
No. A boat (ground-tackle) anchor holds your position by gripping the seabed. A sea anchor never touches the bottom — it creates drag in open water to slow drift and hold your bow into the seas. For seabed ground tackle, see MAURIPRO’s anchoring equipment guide.
What size sea anchor do I need for my sailboat?
Match the unit to your boat’s length as a starting point — MAURIPRO’s Lalizas Standard series is sized from 15 ft up to 45 ft. If your boat is heavier than average for its length, size up within the range rather than choosing strictly by length.
Can the same device work as both a sea anchor and a drogue?
Yes, for the Lalizas units MAURIPRO carries — the manufacturer rates the same cone-and-bridle design for use as a sea anchor off the bow or a sea brake/drogue off the stern. Lalizas’s own Professional-series packaging is labeled “Professional Drogue” even though the identical unit is sold as a “Sea Anchor.”
What is a series drogue, and does MAURIPRO carry one?
A series drogue strings many small cones along one long line to spread drag evenly and resist yawing astern in breaking seas — it’s a well-known offshore heavy-weather design. MAURIPRO’s current lineup is the Lalizas Standard and Professional single-cone sea anchors/drogues described in this guide, not a dedicated series drogue.
