Abstract
Let U be the classical unital in PG(2, q<sup>2</sup>) secant to ℓ<inf>∞</inf>. By deriving PG(2, q<sup>2</sup>) with respect to a derivation set disjoint from U we obtain a new unital U′ in the Hall plane of order q<sup>2</sup>. We show that this unital contains O'Nan configurations and is not isomorphic to the known unitals of the Hall plane, hence it forms a new class of unitals in the Hall plane.
