1. Boat Size

The size of your boat is a crucial determinant of the type of davit system you can install. Larger boats, such as yachts or cruisers, often have the capacity for robust systems like hydraulic platforms or stern-mounted lifts. In contrast, smaller or mid-sized boats may be better suited for simpler, lighter systems like manual davits or pull-up/slide-up models.

• Structural Considerations: Ensure your boat’s design and structure can support the additional weight and stress of the chosen davit system. For instance, hydraulic platforms may require reinforced transoms or swim platforms.
• Space Constraints: The physical space on your boat’s deck or swim platform will dictate the type and size of the davit system you can install. Compact designs work well for boats with limited stern or deck space.
• Boat Usage: Think about how you plan to use your boat. If you frequently embark on extended trips with significant dinghy use, a hydraulic platform may be ideal. For casual, short-distance boating, simpler systems could suffice.

2. Dinghy Weight

The weight and size of your dinghy, including its outboard motor and additional gear, play a pivotal role in choosing the right davit system.

• Weight Capacity: Determine the total weight of your dinghy, including accessories like fuel tanks and batteries. Heavier dinghies require high-capacity systems such as hydraulic or electric davits.
• Impact on Performance: Adding a heavy davit system and dinghy can alter your boat’s trim and performance. Boats sensitive to weight distribution should opt for lightweight davit systems or consider offloading weight from other areas.
• Safety Margins: Choose a davit system with a weight capacity well above the combined weight of your dinghy and gear to ensure safe operation and longevity.

3. Platform Height Over Water

The height of your boat’s platform relative to the water significantly affects the type of davit system that will work for you.

• Low Platforms: If your platform is closer to the water, manual or electric davits can be effective since they require less lifting power.
• High Platforms: Boats with platforms significantly above the waterline may need hydraulic systems or reinforced electric davits. Higher lifts require more power, and the system must compensate for the additional strain.
• Accessibility: Ensure the chosen davit system provides easy access to your dinghy for loading, unloading, and securing, even in challenging sea conditions.

4. Economy

Budget is always a consideration, but it’s essential to balance cost with functionality and durability.

• Initial Investment: Manual davits are typically the most affordable, followed by electric systems, with hydraulic platforms being the most expensive.
• Maintenance Costs: Hydraulic and electric systems may have higher maintenance requirements, including hydraulic fluid changes and motor servicing. Manual systems generally have lower upkeep costs.
• Long-Term Value: Consider the long-term benefits of a higher upfront investment. A durable, high-quality davit system can save money over time by reducing repair and replacement costs.

5. Automation Level

The level of automation you choose will depend on your budget and your preference for convenience.

• Manual Systems: These are cost-effective and reliable but require physical effort to operate. They’re ideal for lighter dinghies and for boaters comfortable with manual handling.
• Electric Systems: Electric davits simplify the process with powered winches, offering a balance between manual effort and full automation. These systems are suitable for moderate-weight dinghies and mid-sized boats.
• Hydraulic Systems: Fully automatic hydraulic systems provide the ultimate convenience, especially for larger, heavier dinghies. However, they come at a premium cost and may require professional installation.

6. Platform Length, Fixed vs. Rail Systems

When considering davit systems for your dinghy, it’s essential to account for the length of your platform and the weight of your dinghy. These factors can significantly affect your boat’s driving characteristics, particularly when storing heavy dinghies or jet skis (300 lbs and up) on platforms longer than 30 inches.

• Fixed Series (F): These systems store the dinghy or jet ski completely outside of the swim platform. While this setup may work for smaller platforms (less than 900 mm or 35 inches deep), it can disrupt the boat’s balance and hydrodynamics. The uneven weight distribution at the stern can lead to a stern-heavy boat, making it harder to plane, reducing fuel efficiency, and compromising handling, particularly in adverse conditions.
• Rail Series (R): Designed to pull the dinghy or jet ski closer to the transom, the R Rail Series minimizes the negative impact on boat performance. By improving weight distribution, this system preserves the boat’s trim, stability, and overall performance. It is an excellent choice for platforms 900 mm (35 inches) or deeper, offering enhanced safety, reliable handling, and better hydrodynamics.
• Recommendations:
  • Choose the F Series for platforms less than 900 mm (35 inches) deep.
  • Opt for the R Series if your platform is 900 mm (35 inches) deep or more for better weight distribution and performance.

Conclusion

Selecting the right dinghy davit system involves a careful assessment of your boat’s size, the dinghy’s weight, platform height, budget, automation needs, and platform-specific requirements like fixed versus rail systems. Larger boats with high platforms and heavy dinghies often benefit from hydraulic systems, while smaller boats with lighter dinghies can use manual or electric options. For platforms longer than 30 inches, choosing an R Rail Series system can significantly improve performance and handling.

By understanding your specific needs and constraints, you can invest in a davit system that enhances your boating experience, ensuring safety, ease of use, and functionality for years to come.
