I'm new so this may seem like a silly question. Can I raise the sail for a short period while I am tied to the dock in light wind? Can I let the head sail out while I am at the dock? For example let's say the wind is 5 knots and I want to unfurl my head sail to make sure it's all the way up and also to make sure the halyard is tight. Or perhaps I want to raise the main so I can flake the sail properly. I assume if all the sheets are loose and the sails are fluttering in the light wind this should be possible. Thoughts?
