Hung neatly on lifelines
We used to coil them up into loops small enough to stuff in the starboard cockpit pocket, but I always hated losing that area for storing the winch handle, handheld VHF, soda bottle, what-have-you.
The admiral has a nifty way to coil up & secure lines she learned as a kid, and I realized we could use it to implement a system that I had originally seen to clean-up the unused part of the lines in a hemp-house theater for their fly system backstage.
I'll try to get a picture this weekend, but basically, we coil the halyard into 1' loops. We take several wraps around the center and leave enough line to push a loop through the top of the coil, grab it on the other side & put the end of the line over the lifeline & though that loop, then pull back down on the line to close the loop tightly on it. Especially with the stopper knot at the end of the halyard, the last part of the line stays inside the loop & holds the coils neatly on the lifeline.
I know it's not explained very well & a picture would be greatly helpful. Maybe I can even do a step-by-step. The end result is a very shipshape-looking, tidy organization of the halyards that don't take up bulkhead or pocket space & are easy to shake out when lowering the sails.
You can catch a glimpse of the mainsheet halyard on the right side of the attached picture.
