6. Operating your winch

Fig. 6.0.1

Ocean Winches 34−65 are single speed powered winches & manual 2 speed, these winches employ an overide ratchet gearing for safety when winching manually.

Ocean Winches 66−77 are 2 or 3 speed powered and manually operated, they will not drive electrically while the winch lock-in handle is in the drive socket.

1.Adjust the feeder arm so that the rope tails into a secure area away from the incoming line.

2.There must be at least 3 turns of rope around the winch before being passed across the feeder arm in to the wavespring self tailing jaws.

3.Use the winch handle or electric switch to operate the winch.

Remove handle after use.

NEVER hold the incoming rope to the winch while the winch is operated. Only control the rope leaving the winch.

4. Pay out line as per manual winch.

ALWAYS switch off the winch at the circuit breaker/isolator after sailing or when leaving the boat to prevent accidental operation.

34-77 specifications

The Lewmar 34-77 is a sophisticated and reliable winch designed for sailing enthusiasts seeking both performance and ease of use. This versatile winch is part of Lewmar's extensive range, known for its innovative engineering and high-quality materials. The 34-77 model combines strength, durability, and advanced features, catering to a variety of sailing conditions and user preferences.

One of the standout features of the Lewmar 34-77 is its self-tailing mechanism. This technology allows sailors to operate the winch without manual assistance in securing the line, providing ease of handling, especially when managing larger sails or when single-handed sailing. The self-tailing design features a robust, integrated clutch that securely holds the line while the winch is engaged, ensuring optimal performance without slipping.

The winch is constructed from high-grade materials, with a focus on maximizing corrosion resistance and longevity. The aluminum construction not only makes the winch lightweight but also provides exceptional strength, allowing it to handle heavy loads with ease. The hard-anodized surface treatment enhances protection against wear and abrasion, ensuring the winch can withstand the harsh marine environment.

Another characteristic that distinguishes the Lewmar 34-77 is its innovative gearing system. The winch features a 2-speed operation, allowing sailors to choose between higher speed for quick trimming and more power for heavy loads. This versatility enables a more tailored approach to sailing maneuvers, enhancing the overall sailing experience.

The design of the Lewmar 34-77 is also user-centric, incorporating a smooth and ergonomic drum. This feature minimizes friction, enabling easier line handling and increased efficiency. The winch’s low-profile design ensures that it doesn't obstruct movement on the deck, making it an ideal choice for both racing and cruising vessels.

In summary, the Lewmar 34-77 is a high-performance winch that embodies the essence of modern sailing technology. Its self-tailing mechanism, durable materials, efficient gearing, and user-friendly design make it a preferred choice among sailors who demand reliability and efficiency in their equipment. Whether you're racing competitively or enjoying a leisurely cruise, the Lewmar 34-77 ensures you have the tools necessary for a successful and enjoyable sailing experience.
