For comparison I use

3/8 - 26' powerboat (hauled out for storms)
5/8 - 38' Beneteau
7/8 - 58' powerboat
I agree - 1/2" is all that is needed or they line will not stretch, putting more load on cleats. I have a CS27 of about the same displacement and have always used 1/2" double braid nylon. I also have a small snubber in the bow and stern line. I have had no issues in the 5 years I have had the boat. It does blow here - the wind hit 40 knots in the harbour last night and was measured at 52 knots a few miles away. It is blowing as I type - speed 28 knots with gusts of 38 knots.
