The hatch on the right, is that a cig factory hatch?

The fatboy and the white (Pure Pressure) boat are both the same factory hatches for a staggered engine boat

Pure Pressure
Same as fat boy

This was indeed the old 35' cigarette Ajac Hawk, which was originally Joe Ippolito's Michelob Light. After racing the 35' footer for one year (Jerry had a choice between purchasing the 35' hull that later became 'Mighty Mouse' or Michelob Light - he chose the latter because of a better finishing record) he had Cigarette put a block into a 39' mold to create the 37.6 footer. AFAIK, it was the *only* 37.6 footer that had the beveled deck from the wide beam 36'. Jerry preferred that deck to the flat-style of the 35' or the 'split level' of the 39'
