Burning at the Waterline

The Burning Ship map z -> (|Re z| + i|Im z|)^2 + c iterated over the parameter plane, framed at c = -1.7545 - 0.0355i and half-width 0.0345 so the two mast groups, the hull wedge and the keel all sit inside the crop. The real 2 by 2 Jacobian is carried in scaled form, so the distance estimate spans about 250 decades with nothing underflowing. That log distance splits into an inward and an outward leg, with sky, bloom and smoke gated to the outward side.
