This came out reasonable well in the end. Made use of half stealers to increase the number of hull planks from 5 to 7 towards the stern in the planking band next to the garboard planks. After realising I can use my floor mounted sander in my garage to shape the half stealer it went much faster with the 2nd, 3rd and 4th ones... (There are two half stealers ports side and two stealers starboard side in the first planking bamd)
