How to Choose the Right Lewmar Windlasses
Determining Windlass Power Requirements by Vessel Size
The foundation of selecting the right Lewmar windlass begins with matching power capacity to your vessel's dimensions and displacement. For boats up to 45 feet, the Lewmar V4 series with 1600W 12V motors provides sufficient pulling power for typical anchoring scenarios. These units deliver reliable performance for recreational vessels where anchor weights typically range from 35-75 pounds and rode combinations include chain-rope configurations.
Larger vessels exceeding 45 feet or those carrying heavier ground tackle require the enhanced power of 2000W 24V V4 systems or the robust V6 series. The V6 windlasses represent Lewmar's heavy-duty category, engineered for commercial applications and larger yachts where anchor systems may exceed 100 pounds. When selecting between 12V and 24V configurations, consider that 24V systems offer improved efficiency and reduced current draw, making them preferable for extended anchoring operations or vessels with comprehensive electrical systems.
Electric vs Hydraulic Motor Configurations
Lewmar windlasses at MAURIPRO are available in both electric and hydraulic drive systems, each offering distinct operational advantages. Electric windlasses using 12V or 24V motor gearbox assemblies provide straightforward installation and maintenance, making them ideal for recreational boaters who prioritize reliability and ease of service. The electric V4 and V6 series feature sealed motor housings and corrosion-resistant components designed for marine environments.
Hydraulic motor gearbox systems, such as the V6 Hydraulic Motor Gearbox (69000408), deliver superior power-to-weight ratios and consistent performance under heavy loads. These systems integrate with existing hydraulic infrastructure on larger vessels, offering virtually unlimited duty cycles without overheating concerns. Hydraulic windlasses excel in commercial applications or on yachts where multiple hydraulic systems already exist, providing smooth operation and precise control during anchoring maneuvers.
Deck Unit Configuration: Gypsy and Drum Options
Lewmar windlass deck units come in specialized configurations to accommodate different rode handling requirements. Gypsy-only deck units are designed specifically for all-chain rode systems, providing maximum holding power and precise chain control during deployment and retrieval. The gypsy's pocketed design matches standard chain sizes, ensuring proper engagement and reducing slippage under load.
Combined gypsy and drum configurations offer versatility for mixed rode systems incorporating both chain and rope components. The drum section handles rope rode efficiently while the gypsy manages the chain portion near the anchor. Left-hand (LH) and right-hand (RH) orientations accommodate different deck layouts and operational preferences, with the designation indicating the chain feed direction when viewed from the operator position.
Voltage System Compatibility and Electrical Requirements
Proper voltage selection ensures optimal windlass performance and integration with your vessel's electrical system. 12V windlass systems suit smaller vessels with standard automotive-style electrical configurations, offering compatibility with most battery banks and charging systems found on recreational boats. These systems typically draw 80-120 amps under working loads, requiring adequate battery capacity and properly sized conductors.
24V configurations provide enhanced efficiency and reduced current draw, making them preferable for larger vessels or those with extended anchoring requirements. The higher voltage allows for smaller wire gauges over longer runs and reduces voltage drop concerns common in larger boat installations. When upgrading motor gearbox assemblies, such as the 24V units available for 3000/3500 series windlasses, ensure your charging system and battery bank support the voltage requirements.
Installation Considerations and Deck Space Requirements
Vertical windlass installations require adequate below-deck clearance for motor gearbox assemblies and proper alignment with chain lockers or rode storage areas. Lewmar V4 and V6 series windlasses feature compact vertical designs that minimize deck footprint while maximizing mechanical advantage. Consider the deck thickness and reinforcement requirements, as windlasses generate substantial loads during operation that must be properly distributed through backing plates and structural supports.
Component accessibility affects long-term maintenance and serviceability, making modular designs advantageous for professional installations. Separate motor gearbox assemblies allow for individual component replacement without complete system overhaul, reducing maintenance costs and minimizing downtime. When planning installations, ensure adequate access to electrical connections, hydraulic fittings, and mechanical components that may require periodic service or inspection.

Frequently Asked Questions
What's the difference between the Lewmar V4 and V6 windlass series?
The Lewmar V6 series represents their newer, heavy-duty line designed for larger vessels, with modular components like separate motor gearbox assemblies and deck units that can be configured for specific needs. The V4 series offers integrated 1600W (12V) or 2000W (24V) units that combine the gypsy and drum in a single vertical electric windlass, making them ideal for mid-size boats. V6 systems provide more flexibility with hydraulic or electric motor options and higher pulling capacity, while V4 units are more compact and cost-effective for boats requiring moderate anchor handling power. MAURIPRO stocks both series to accommodate different vessel sizes and anchor system requirements.
Can I buy just the motor gearbox assembly separately for my existing Lewmar windlass?
Yes, MAURIPRO carries standalone motor gearbox assemblies for several Lewmar models, including the V6 24V Motor Gearbox Assembly and the 24V Motor Gearbox for 3000/3500 series windlasses. This allows you to replace a failed motor unit without purchasing an entirely new windlass system, which can save thousands of dollars. The V6 series also offers a hydraulic motor gearbox option for boats with existing hydraulic systems. Make sure to verify your exact windlass model and voltage requirements before ordering to ensure compatibility with your existing deck unit.
What does 'Gypsy Sold Separately' mean for the Lewmar V6 deck units?
Lewmar V6 windlasses use a modular design where the gypsy (the grooved wheel that grips your anchor chain) is sold as a separate component from the deck unit housing. This allows you to select the correct gypsy size and pitch to match your specific anchor chain dimensions, whether you're running 6mm, 8mm, 10mm chain or different pitches. MAURIPRO stocks both the 'Gypsy Drum' deck units and 'Gypsy Only' deck units in left-hand and right-hand configurations. You'll need to purchase the appropriately sized gypsy separately to complete your windlass installation.
Should I choose 12V or 24V for my Lewmar windlass installation?
The voltage choice depends on your boat's electrical system and power requirements - 24V systems provide more efficient power delivery and are typically used on larger vessels or boats with higher electrical demands. MAURIPRO's Lewmar V4 1600W units operate on 12V, while the V4 2000W units require 24V, giving you 25% more pulling power with the higher voltage option. If your boat already has a 24V house system, the 24V windlass will integrate seamlessly and provide better performance under load. For boats with 12V systems, the 1600W units still provide excellent anchor handling capability for most recreational vessels without requiring electrical system modifications.
What's the advantage of choosing a hydraulic motor over electric for the Lewmar V6?
Hydraulic windlasses offer superior power-to-weight ratio and can operate continuously under heavy loads without overheating, making them ideal for commercial applications or boats that frequently anchor in challenging conditions. The Lewmar V6 Hydraulic Motor Gearbox provides consistent pulling power regardless of battery state and eliminates the high electrical current draw that electric windlasses require. Hydraulic systems are also more reliable in marine environments since they're less susceptible to corrosion and electrical issues. However, hydraulic windlasses require an existing hydraulic system or the installation of a separate hydraulic power unit, which MAURIPRO can help you specify based on your boat's configuration and power requirements.
