Depending on the kind of cat you have you can be off the ramp in about 10 minutes (including parking your car). I always launched off of a trailer. I get everything done except raising the sails (on a boat without a roller furling jib I furl the sail around the forestay). Then, back down the ramp and get the boat in the water. I will usually jump on the boat when the bows begin to tip up and ride it the rest of the way in. I then get the boat to the dock or the sandy/grassy shore, get off the boat and park the car. Come back and sail away. I do all of the prep work off to the side of the line for the ramp. Rarely will the jokers with powerboats be done as fast as I am.
