Going along with what boatman said, given your seasonal use, wood may not be the best choice. Wooden boats are great but they require maintenance and being designed for the environment
that they are used in. Seasonal use generally means that you will haul the boat and be gone for a long period of time which will allow the boat to dry out. In addition, you will need to do repairs
from time to time which are a lot more difficult without having your own shop nearby. Wooden boat repair is nothing to be afraid of skills wise but it requires the right tools and the time. The sun wreaks havoc on wooden boats beyond just the paint
. In addition, that boat does not appear to have any form of ventilation that can be left open when you leave it so you would need to modify it. And depending where you are, things like worms can be a problem as well. I don't mean to scare you with this but wooden boats in the south can be lots of work. I have spent most of my time sailing wooden boats and I love them but if sailing is your goal and not maintenance, fiberglass
Sorry, I have never sailed the Dufour so I can't help you there.
