So i am wondering if in my build with my jersey skiff i should use a curved stuffing tube like the one in this picture
www.google.com/search?q=submer...%3B600%3B246the only difference is that the tube would end at the trandsom along with the rudder.

Or this one

one again the only difference is that the tube will run to the trandsom along with the rudder

I am going for a scale look so i am wondering if the straight tube will bring any disadvantages?
thats it.

thank you
