I know time doesn't matter usually, or for most, but there is a mental blocking if you know it is even just a bit more cumbersome, as to whether you change kitesize
From a 3 year old post where I compared setting up a Peak with a LEI, but have removed the LEI part here in the copy:
With my Peak4, I timed it once on a summerday, just to see HOW fast I could be ready (at a spot where I could launch and land in the parking lot just at the side of the car).
120 seconds from I parked the car, till ready to go on the water, meaning 2 minutes it took me to:
Foil out of the car, assembled (if not, I only got one screw so does not take long).
Harness out of the car and on (summer, so only shorts, would take longer if having to get in a shorty).
Kite out of the bag, lock the car and hide the key.
Put the kite on the ground and roll the lines out and launch, trusting lines are sorted as they usually are on these kites.
Packing down, I had to use 3 minutes before I could drive away:
Backing the kite down.
Get the key, and put harness in the car.
Rolling lines up.
Put it in the bag.
Foilboard in the car.
And it would be closer to 3½ minutes, if I were to get in dry clothing, meaning shorts and maybe T shirt.
The most time consuming part is if you have a full wetsuit, especially the warmer ones, it takes much longer than rigging and launching a kite, I found out.
I dont rush like above normally, but because I had been out in one spot, wind died, I drove to another, wind okay - I had the chance to time HOW FAST I could be, from parking the car till standing ready to go in the water, kite in the air, board under my arm
It was fun, and amazingly fast, I had an idea, but did not knew exactly !
With big lightwind foil kites, setting up is very fast too, a bit longer though.
But packing double skin foil kites DOWN, is horrible - it takes so much longer to get these deflated and packed in the bag, that everything you gain on the start compared to LEI's in terms of less time, is more than lost.
It does not matter as much though, as the important part is usually a quick setup, so you can get on the water while there is wind.
