With enough light ships you can re-route most of the New World trade to your home node. England does only need to colonize the American East Coast to control Chesapeake Bay and then they can use their fleet to re-reoute trade from the Carribean. Works like a charm.imo the trade system is broken (or at least badly designed) if being the prime maritime power in the world doesn't increase your trade income enough to make a large fleet profitable.
