i have a 1978 baron it is a great boat.i think a 1983 could be one of the first xlt's. the first powerplay xlt's had a round keel also. is the hatch wood or fiberglass? the fuel tank in the floor is a much better ride then in the bow. and the barons have no hook in the end of the hull. the id on my is on the right rear. pm tommymonza on this site his brother was the builder. hope this helps.
