I am curious to know the distance from the top of the deck planks to the bottom of the ports as well.This is what I understood. My measurements are not accurate with the contract as this would not fit into this kit design.
Also from the contract:
height of the upper side of the lower port sill from the upper side of the plank of the upper deck 1 ft 9 ins, (11.1mm at 1:48)
Thanks Grant
