Writing the article we just published on the Adventure 40 steering system, including rudder and self-steering options, got me thinking about the true cost of autopilots and how they compare to vane gears.
Let's take a look, since this is a subject that's relevant to all of us, regardless of whether or not we are thinking of buying an Adventure 40, and particularly to those with the end goal of offshore live-aboard sailing, while trying to stay under US$100,000 for the entire project.
Benefits Comparison Overview
But before we get into money, a quick overview.
When compared to autopilots, vane gears:
- Are simpler.
- Are relatively easy to repair, even at sea, with basic tools and a few spares.
- I have done this several times, including while on a challenging single-handed passage against the Christmas Winds from St. Maarten to Barbados—what was I thinking?...Well, there was a woman involved...
- Do not use electricity—more on how big a win that is in a minute.
- May, depending on design, be able to act as a backup rudder.
- Are easier to use and require less skill, since vane gears, at least if we want them to steer well, require a good understanding of sail trim to balance the boat properly.
- Will work both motoring and sailing.
- Are less vulnerable to damage than a vane gear hanging on the stern.
Note: this is a summary, see Further Reading for much more on self-steering options.
