What Are The Main Types Of Anchor Winches? Choose The Right System For Your Boat

At the highest level, the two main types of anchor winches are the Drum Winch and the Windlass Winch. Windlasses are further divided into two common configurations: horizontal and vertical.

These designs approach the task of retrieving and storing the anchor rode (the line or chain) in fundamentally different ways, which directly impacts their suitability for different boats and anchoring needs.

The core difference is simple: a drum winch stores the entire anchor rode on its spool, while a windlass pulls the rode in and deposits it into a separate anchor locker. This single distinction drives every other trade-off, from deck space to installation complexity.

What are the main types of anchor winches? Choose the Right System for Your Boat

The Core Principle: A Lifting Machine

An anchor winch is fundamentally a lifting winch, not a pulling winch. This is a critical distinction.

The Demands of Lifting

A pulling winch, like one on a 4x4, is designed for horizontal loads and intermittent use. An anchor winch, however, must vertically lift the full weight of the anchor and rode against gravity and hold that load securely.

Safety and Control

This requires specialized braking systems and robust gearing to prevent the anchor from running out uncontrollably. Every anchor winch is engineered first and foremost for safety and the power to hold a load.

The Two Primary Designs: Drum vs. Windlass

While both are lifting machines, their method of managing the anchor rode dictates their form and function.

Drum Winches: All-in-One Simplicity

A drum winch features a large spool that the entire anchor rode—rope and chain—is wound onto directly. Think of it like a massive fishing reel for your anchor.

This design is often favored for its simplicity. It is an economical and self-contained system that neatly manages the rode, preventing tangles. Many drum winches also offer a "freefall" feature for rapid anchor deployment.

Windlass Winches: Separating Power from Storage

A windlass does not store the rode. Instead, it uses a geared, rotating head called a gypsy (for chain) or a capstan (for rope) to grip and pull the rode.

The rode is then fed through the windlass and deposited down a pipe into a dedicated anchor locker below the deck. This separation of function allows for a more compact on-deck footprint.

Vertical vs. Horizontal Windlass

Windlasses come in two orientations, each with distinct advantages.

Vertical Windlass: The motor and gearbox are mounted below the deck, with only the compact capstan and gypsy showing on top. This saves valuable deck space but requires significant room below for both the machinery and a deep anchor locker.
Horizontal Windlass: The motor, gearbox, and gypsy are all contained in a single unit mounted horizontally on the deck. This requires more deck space but is often much easier to install and service, as all components are readily accessible.

Understanding the Trade-offs

Choosing between a drum and a windlass system is a matter of balancing your boat's design constraints with your operational needs.

Space and Installation

A drum winch requires a significant amount of horizontal space on or below deck to accommodate its width. Installation is relatively straightforward as it's a self-contained unit.

A windlass requires a deep and clear anchor locker directly below it for the rode to fall into. A vertical windlass, while saving deck space, complicates installation by passing the drive shaft through the deck.

Rode Management

The primary advantage of a drum winch is that it spools the rode perfectly every time, eliminating the risk of the rode tangling or piling up in the locker (a problem known as "castling").

With a windlass, you must ensure the anchor locker is deep enough for gravity to flake the rode properly. If not, you may have to manually manage the pile to prevent jams during retrieval.

Cost and Hassle

Drum winches are often seen as the most hassle-free and economical solution, especially for small to mid-sized boats. Their all-in-one design simplifies purchasing and setup.

Windlass systems can be more complex, involving the winch itself plus the considerations for the anchor locker below. They are the standard on larger vessels where heavy, all-chain rodes are common.

Making the Right Choice for Your Boat

Your decision should be guided by your vessel's layout, size, and your budget.

If your primary focus is simplicity and cost-effectiveness on a small to mid-sized boat: A drum winch is often the most direct and reliable solution.
If your primary focus is maximizing deck space on a larger vessel: A vertical windlass provides the lowest on-deck profile, assuming you have a deep anchor locker.
If your primary focus is ease of installation on a boat with limited below-deck space: A horizontal windlass keeps all components on deck and simplifies maintenance.

Ultimately, the best anchor winch is the one that integrates seamlessly with your boat and makes the process of anchoring safer and less strenuous.
