Chad has been doing this so freaking long it comes natural and he forgets that for eveyone the kayak isn't an extension of their body... CHAD can stand in the kayak, kneel in the kayak and do just about (okay) everything in the kayak...
To get out of the kayak you can just turn, put your feet down and stand, but the kayak will want to move away and you'll fall on your ass backwards, get all wet and the folks on the ramp will fall all over themselves laughing. UNLESS, you are 6'4" tall and 300 pounds. Then... they blow snot out of their noses trying not to laugh. ( Not that "I" have ever done that.)
To control the sideways slide of the yak you can:
turn way from the ramp side and step off on the slightly deeper water with the kayak across the ramp, this way if the kayak tries to slide it is against the shallows and can't move..
Reach acoss and poke your paddle edge in the bottom and hold the yak in place and then stand, which holds the yak in place and it can't move.
Hold the kayak with both hands, plant your feet solidly on the bottom, lean forward slightly as you stand so your ass clears the plastic and then stand ... (Doesn't work for gimps like me with fake knees...)
Once you are more comfortable with your yak you'll be able to slide up to the bank and hop out like a 12 year old hopping off his bike at the door when he has to pee.
