Hi ace,
thank you very much for your input.
Like you said, the hull definitley isn't wide enough for a skeg like i've drawn it.
I kind of knew the way I drew it had to be incorrect, but I couldn't and still can't make sense of the references I have.
So, what you are saying is that the shafts are enclosed inside of the skegs. Ok, this seems fine.
I just can't get how the skegs should be positioned as not to interfere with the screws and/or outside rudders.
I drew up some quick sketches and I'm still quite puzzled:
Should it look like in figure "1" or "2"? I favour 1, because 2 would need some sort of "cutout" for the screws, I guess. Pretty implausible, I know, but this whole system seems pretty insane anyway...
