    Likely a noob question but I gotta ask it.

    Why are the shroud lines so short when you order a chute from apogee for example? Is it to reduce drag or save cost?

    I re-tied my plastic chutes to longer lines for full effect and better drag. I think they are roughly 24-30 inches of line. I will get photos this weekend when I get home.

    Sorry for butting in but there is no such thing as a parasheet. The word parachute is French para=shield + chute=fall. Literally ant object that shields from a fall can be called a parachute.
    Many real parachutes can be laid out flat.

    A good rule of thumb for most is the length should be equal to the diameter, but I'm sure if the lines are longer it won't matter much. When I tie my lines on plastic chutes I always make sure the lines doesn't cinch on the plastic chutes because this tends to tear the chute up so I always makes sure that ther is gap between the knot and the chute.

    The only chutes I've bought are the ones that come with kits. I make all of my larger ones. I use shroud lines 1.5 x the chute diameter. I've found that the longer length reduces the amount of swinging that happens and stabilizes the chute much better. Of course a center spill hole helps that a lot too.

    So if it's not a real parachute it must be fake.
