Assuming this is your first ship, I highly recommend a book such as Frank Mastini's "Ship Modeling Simplified". It shows the method below. Roughly speaking, all of your planks now except the garboard plank (the one along the keel on either side) will be tapered at the bow. To some people here, it may be anathema, but some may have to be tapered to a point. I see lots of beginner instructional videos suggesting this. At the stern, they may taper or they may leave v-shaped gaps. These you can fill with suitably trimmed off cuts. This method is just one. There are others far more sophisticated and "realistic".
My view, and I've only done a couple of models, is that you can graduate to those methods if so inclined. Or you may be happy with this. There are also a couple of videos on YouTube by Leon Griffiths on how to plnk a sharp bow hull or how to plank rounded bow hull. When you lay the plank against the hull the plank will tell you how it will happily lie. You have to taper it to allow it to do so. Of you don't, it will complain and "clinker". Of course, you have to bend it around the bow in the other plane. You can do this in different ways. You can't bend it in two different planes and expect it to lie flat. Well, experts can but that is not you and me. See "spiling".
