You can seize the cannon rope be wrapping thread around it, the correct way is a hook on the rope and an eyebolt in the bulwark I just used a eyebolt on the end of the rope.
It's very hard to tell from the photos but you may need to fair the frames some more. Fairing the frames is one of the most important parts of planking. Check to see if the plank is sitting on the corner of a frame. Take care around the bow there is a big change in profile in the first four frames lots of tapering and working out the best run for the planks.
Take your time the first planking is as important as the second. Before gluing a plank mark the frames where the plank goes then place the next plank on the marks to see how flat it sits on the frames. If it doesn't sit flat on all frames adjust as required. Only taper one side of the plank so it fits up against a straight edge on the other plank.
Good luck.
