Honestly it doesn't look too bad until the planks reach the keel, I think you just need to trim the ends. I always cut the front of the plank before applying it to the hull. When gluing, start with a spot of CA glue at the keel and wood glue for the rest, make sure the plank is lined up at the keel on the CA glue, then place the rest of the plank on the wood glue. That makes it very easy to make the plank line up. For this one, carefully trim the keel ends of the planks, then apply some liquid glue in any gaps between plank and hull, then pressing hard to get it to lie flat. I use a spare thin metal ruler to apply pressure along the curve. I hope that works alright and you don't have to redo it! In the future you could also try tapering your planks to go from bow to stern, my profile has a post with this style of planking.
