I couldn't deal with the Pearl being smaller than the Queen Anne's Revenge so I bought two and went to work. She is now identical in length to the QAR to the stud. The two front mast positions are the same as QAR. I moved the the stairs forward two studs to run a fourth cannon under them. Widened the walkways and added pull out grating. Also had to have the windows in sets of three...that is too much of an identity point for me.
It obviously is not as grand as the LDD versions but I am much happier.
