The Jeanneau has been winterized. Nothing special. The boat remains in the water, that makes life easier.
I flushed the (raw water cooled) engine with a few litres of coolant and also put some coolant in several though hull valves. I emtpied the water tank and did a bit of cleaning. It still looked good on the inside. I will leave this tank open.
After that I still had some energy so I sanded the carbon tape on the boom of the new project. It was cold in the shed so I soon called it a day.
