  The boundstate problem in 2+1-dimensional large-N Yang-Mills theory is
accurately solved using the light-front Hamiltonian of transverse lattice gauge
theory. We conduct a thorough investigation of the space of couplings on coarse
lattices, finding a single renormalised trajectory on which Poincar\'e
symmetries are enhanced in boundstate solutions. Augmented by existing data
from finite-N Euclidean lattice simulations, we obtain accurate estimates of
the low-lying glueball spectrum at N=infinty
