I have had an in mast furling main sail on my 410 for two years now. I live in Ontario Canada and my current sail storage procedure has been to lower the main and store it in the boat. I was wondering if anyone had any experience storing the sail in the mast for the winter? It seems to do quite well in this position for the other three seasons. I was wondering if storing it this way on the hard for the winter could have any adverse effects on the sail?
