Hi Wallace,
It's difficult to say without a pic. However, if she lies flat without tapering then it's probably OK.

Every hull is different and every plank an individual so there are no predictions as to how you will need to do yours. Practice makes perfect and increases confidence. Victory is only my second build and the single planking worked out better than the thinner double planking on the first. The second planking I soaked and removed after doing about half one side and redid it. Did I mention perseverance?

Good luck and don't forget if it's not clinkering it's better than some, although these thick planks will take a bit of sanding to smooth off minor clinkering. In 1 or 2 spots I laid another short length of plank against the raised edge and then planed and sanded back until flush and virtually invisible. I only did this where the clinkered edge was over 0.5mm above the next plank as this would have entailed a lot of sanding and risked over thinning the surrounding planks.

I hope this will be of some help.

Laury
