I just finished installing my Cape Horn unit yesterday and am very pleased
with it. More work to install than some other types but much cleaner and
attractive when you are done.

I don't think this unit would be oversized on a 26 foot boat. There is a
PDF file scale drawing on the site with a scale. If you fiddle a bit with a
scaling copier or computer graphics program and have a drawing of your boat,
you can see how it would look. The height of the wind vane tower can be
lowered.

Highly recommended.
