  We extend the quasilocal formalism of Brown and York to include
electromagnetic and dilaton fields and also allow for spatial boundaries that
are not orthogonal to the foliation of the spacetime. The extension allows us
to study the quasilocal energy measured by observers who are moving around in a
spacetime. We show that the quasilocal energy transforms with respect to boosts
by Lorentz-type transformation laws. The resulting formalism can be used to
study spacetimes containing electric or magnetic charge but not both, a
restriction inherent in the formalism. The gauge dependence of the quasilocal
energy is discussed. We use the thin shell formalism of Israel to reinterpret
the quasilocal energy from an operational point of view and examine the
implications for the recently proposed AdS/CFT inspired intrinsic reference
terms. The distribution of energy around Reissner-Nordstr\"{o}m and naked black
holes is investigated as measured by both static and infalling observers. We
see that this proposed distribution matches a Newtonian intuition in the
appropriate limit. Finally the study of naked black holes reveals an alternate
characterization of this class of spacetimes in terms of the quasilocal
energies.
