We need an FAR reference.

No idea about FAR, but in JAR country, a magnetic compass is required
for motorgliders (self sustainers count, too). No magnetic compass is
required for gliders without a fuel to noise converter.

Bill, you are correct. FAR 91.205 requires a compass for powered
aircraft. No mention regarding gliders. FAR 91.213 requires a
compass for gliders only if it was part of the the equipment
prescribed under which the aircraft was type-certificated. However, I
still feel that a compass is very useful.
