South Atlantic S 600 Windvane FAQ

System Design & Compatibility

Comparative analysis of auxiliary rudder systems for offshore sailing

What size vessel is the S 600 designed for?

It is engineered for large-displacement sailboats, specifically those with a Length Over All (LOA) between 36 and 60 feet.

What type of self-steering system does it use?

The S 600 is an Auxiliary Rudder system. Unlike pure servo-pendulum models, it features its own independent rudder blade that works in tandem with a perfectly synchronized sensing pendulum.

Can it function as an emergency rudder?

Yes. The S 600 is a dual-function system: it operates as a windvane self-steering gear and as a "Ready-To-Go" emergency rudder in the event of a catastrophic failure of the vessel's main rudder.

Is it suitable for boats with hydraulic steering or a center cockpit?

Yes, it is the technically correct choice for these configurations. Being an independent auxiliary rudder system, it does not rely on the mechanical linkages or lines of the vessel's primary steering gear.

Does it require routing steering lines or blocks through the cockpit?

No. One of its main technical advantages is that it eliminates the need for steering lines across the cockpit, keeping the area clear and free of obstructions.

Performance & Operation

How does it perform in light wind conditions?

The S 600 is significantly more sensitive than standard servo-pendulum systems in light airs and faint breezes.

How much steering power does it deliver?

It is the strongest and most powerful model in the entire South Atlantic product range. Due to its position at the absolute aft end of the transom, it optimizes the turning lever arm and can deflect its rudder blade up to 35 degrees to maintain course.

How does it manage the vessel's weather helm?

It allows the ship's main rudder to be locked in a fixed position to counteract and balance out weather helm, leaving the S 600 to handle all subsequent fine tracking and course corrections.

Does it require electrical power to operate?

No. Like all South Atlantic systems, the S 600 is entirely mechanical and operates with zero electrical consumption.

Setup & Adaptability

Is it difficult to install?

No, it is designed for straightforward DIY (Do-It-Yourself) owner installation. The estimated mounting time—from unboxing to sea trials—is only 2 to 4 hours.

Can the unit be customized?

Yes, the S 600 can be custom-tailored to meet the specific transom design and architectural requirements of your sailboat.
