My Nacra has a nice mast hinge pin that makes life easier when raising the mast. My understanding (from the manual) is that it's meant to stay in after the mast is raised; but I've been told I should take it out.
The pin is https://www.murrays.com/product/56-f158/ -- the pin "in its place" can be seen in this pic https://photos.app.goo.gl/mnnNA7PX7XaCEL6n7
What do _you_ do? Keep it in place when you go sailing? Remove it? Why? If you do remove it, where do you keep it so as to avoid losing it?
