A90 TRACON controller reported a B737-900 flight crew executed a missed approach while complying with a published charted visual. The aircraft was reportedly to high on approach. This type of occurrence is allegedly common to newer airframe aircraft according to the controller. The descent rate is slower.

Narrative:
Aircraft X was vectored to and cleared for a charted visual approach. Aircraft was level at 1800 feet indicating 180 knots; on a direct path; 2 miles prior to lyhtt which has a crossing altitude of 1800 feet. One mile prior to lyhtt; the aircraft begins a climb and veers off course. The aircraft goes missed approach. When queried; the pilot stated he was too high for the airport. Given the aircraft's position in reference to the fix; route of flight; altitude; and speed; it is my opinion that the missed approach was due to the flyability of the light visual approach to runway 33L. I believe the aircraft was indeed in a poor position for an approach to the airport. The B737-900 series is a very difficult airframe to descend; slow etc. It is one of the growing number of newer airframes that operate with a high efficiency making the charted visual approach more difficult than with other airframes.
