Do you understand the concept of how the ADXL202 works? They are designed to
work in a one g environment. The gravitational force is exerted on a solid
state (silicon) beam and the beam deflection produces the output which is a
function of the sensed gravitational field which is essentially 1g when the
beam is perpindicular to the gravity field and 0g when the beam is parallel
to the field. Read the data sheets and the application notes that you can
easily find at the AMD site ( http://www.amd.com/us-en/ ). I urge you to do
so.

Very few boats will ever find temselves in a zero g environment. My comments
are directed to a query about a pitch/roll sensor for a sailboat. Just
trying to stay on topic.
