I really wonder if wind driven self-steering gear is better than electronic
gear.

A. Though electronic gear can fail, carrying a few spare units is less
expensive than the initial installation of a windvane system.

B. Though electronic gear consumes power, power generation is not a major
issue for many cruisers.

C. Electronic gear will probably fail at no greater rate than the
wind/mechanical system, and would be infinitely easier to replace a as a
complete assembly than would be a windvane and its associated gearing.

D. Electronic gear takes us much less real estate and leaves an already
cluttered transom untouched.

My two cents. Glad to hear other opinions.
