As a kid in high school, I worked at Graves Boat Yard, Marblehead, Massachusetts. That is where the last wood 12 meter (Easterner) was built. I watched world class boat builders in action. So all that is the basis for my opinion/advice.
My advice is simple. Take an old dingy, row boat, or small sail boat, preferably planked. Rebuild it with hand tools only. Bring it up to sellable condition with your apprentice participating in the proceeds. The basis of boat building is handling curves. That can only be taught by five sensing the experience and working to keep the water from leaking into the finished product. Don't forget the vocabulary of boat building: scarf, chine, scupper, etc. By working on an actual boat, these will fall into place. I would also add that drawing is an important part of learning to use hand tools.
Steven Coyey famously said, "Begin with the end in mind." By working on an actual boat, there is an end to the learning process that will make for meaningful learning.
I worked next to a skilled shipwright. He chewed and I had to learn quickly to stay clear. That was my first learning event. Hopefully you will spare your apprentice that learning feature.
