Hello, first time posting here and hope I'm in the proper sub.

I saw a kayak hoist storage system like this and I'm curious about the forces at play. I understand that with one moving pulley and a tied end, that you gain double mechanical force at the cost of double the rope travel.

In this setup if I pull the ropes free end ten feet, how far will the kayak rise?
Also, if I apply ten pounds of force on the line, how much force is on each component and structure?

My guess is I only have to lift a third of the kayaks weight at once. I am having a tough time visualizing the movement and forces.

Thank you!
