1 pointThere are a lot of wrinkles in the luff so I'd pull the mainsheet in hard then pull the downhaul hard too. The main isn't right up to the top which either means it's shrunk or that someone has cut it down.

You therefore pull the boom down to tension the luff of the sail. 3. The clew shackles to the slider on the boom.
