They are really stable in the water, I can sit with both legs over the same side without in capsizing, as long as I don't look over the side at the same time
I also have a pair of folding wheels on a frame that fit in the front hatch. I just wheel the whole lot into the water, fold up the wheels and stow them, then paddle off. I have a long piece of rope with loads of carabiners on it to clips the kit off when getting in/out of the water.
The kayak itself is so easy to get on from the water, even without fins.
