Typos? Gee, I've enver amde any of those...
Yeah, centering the port does make sense. I was debating it with myself, but I think you've got it nailed.
I can also see the advantage of placing it in the foredeck (and my measurements from this weekend tell me it will fit between the bulkhead and the bow).
However, at this point, I'm leaning toward putting the port in the bulkhead, rather than in the foredeck, even if I do have to work inside the cuddy. Part of this is because I discovered this weekend that the two forward stringers supporting the foredeck are cracking away from it on the port side. I'll reinforce them, but I don't want to do anything that might weaken the structure.
Besides, if it doesn't come out pretty, it won't be so visible.
