With my Freedom Hawks, I use the technique shown in the video linked below to get into and out of them. It makes the launching a lot easier. Getting out is a simple reverse with or without their bows resting on the launch ramp.http://www.youtube.com/watch?v=SnDftsLMW3k
I wish that I could have an H Bar for our Oasis. Now, I hold our Oasis until my wife gets in, then I straddle the yak in front of the seat and sit down. Then, my wife either pedals or paddles forward until we can Mirage out. It works but isn't a picture of style and grace/ease as in the video in the above link.
