Thank you, Paul T., for clearing up about mast rake. As I read it, the only advantage is gravity letting the sail out in light winds; disadvantage: none. Correct? So, basically, it is just another tool to get the CE to the right position if mast placement is restricted.
Frederik: wonderful, what a mighty name!
Arne, I did similar on Ilvy: wrapped the Aluminium mast into a yoga mat, then sewed some canvas around it with a zipper. It was never cold or uncomfy to lay against the mast. However, I think the position of the mast in relation to one's body makes all the difference whether good sleep is possible (not talking about non-sailing related activities...). We had the mast at belly position, so it was possible to sleep sideways (if wanted) with knees drawn in and even spoon. In your foto it looks like the mast is that far forward that it would interfere with your knees when sleeping on the side. Any problems with that? I would imagine similar problems with sleeping on ones back if the mast is at shoulder height.
Cheers, Paul
