Our calculations within the hybrid quark-hadron model of the form factors of the three-nucleon systems are given. Three-nucleon form factors for 0 less-than-or-equal-to q2 less-than-or-equal-to 4 (GeV/c)2 are discussed. Striking six-quark cluster effects are found, with the probability for a nucleon to be in a six-quark cluster about 14%. Needed theoretical improvements in the model are also discussed.
