Breaking news, the bow of my ship is finely finished at long last after three attempts later, I am a happy camper she turned out ok in the end after making a few mistakes on the way be as close as I can get of the real bow.
Now I can more onto the next bulkhead, has will have the upper deck on it and top deck, a bit of cutting out still with the hull till the end of the first section then for there on be a square shape from top deck to water line.
I am glad there isn't a 4th deck to worry about now and didn't really need to add on 10 mm's , too lake now, won't notice it , the bulkhead from the main deck bulkhead has the stair cases to the upper decks be closed in is what the 4th deck is.
On a big high, am glad to see that finished.
