The following images show dimensions and placement for ELCO 80' PT boat deck ventilator. These dimensional images represent a best effort on my part, please confirm dimensions given here for yourself if errors cannot be tolerated.

Deck vent styles for ELCO 80' PT boats according to the plans. Note that I have a photo of the 611 that shows a different deck box near the starboard foot rail, shaped like a larger 103-196 vent facing forward. Also, vent locations changed:
fixed type hood only: PT 103-196
rotary type taper sided hood only: PT 314-367, 372-383, 546-563
rotary type taper sided hood on a rounded rectangular deck box: PT 486-545, 565-624, 731-760
