I am after some information on the ELCO 80ft 103 class, I have gathered conflicting data on the positon of the three rudders relative to the propeller shafts.
Some say inline, others say outboard of shafts.

Port and starboard shafts of early examples were set 47inches from the centre line (keel).

The Italeri plastic kit shows them in line.

I have seen pictures of a latter boats were the rudders are not directly behind the propellers but not sure about early boats like the 103 class.
