Its relevant to the spin. Install the chute and attach sheet lines. Pull the lines back toward the hull, you want to sheet thru the middle of the chute so the foot and leech harden at the same time. Too much pull on the foot or the leech will affect sail trim. May need someone to hold the sheet so you can step back and examine. If you are lucky the shrouds will attach where the block needs to be and no holes will be drilled.
