I know I have small boat guys in the audience. Quick question...

I've been seeing a bunch of small boat exercise and I'm wondering. How far out can they launch? I'm not talking about flying end, dropping the boat off the ramp and going to the beach. I'm talking about launching from a ship and getting there. Also does anyone know the max distance possible? Those are small motors and I don't know if they carry extra fuel onboard (I would tend to think not). Now for the million dollar question. If its shorter than over the horizon then how does this fit in to the EABO concept?
