Yes, it has two double paddles. Paddles and aluminium rods can be taken apart into 2x3 parts for transport.
A small foot pump, a measuring device (polystyrene box) and a carrying bag (thin fabric, aluminium rods have no place in it) are included.
You would probably have to contact sevylor, because I don't know which adhesive to use for the material "Tarpaulin" and which patch is best to use. https://www.sevylor-europe.com/de/p-240-madison-aufblasbares-kajak.aspx#
The version I got (this kit from Digitec) is a 2 (or 1) seater as in the first video. The last video is not from this model: there are no small loops every 4cm at the top to attach seats on this model.
