BTW, Hobie Alter just died a couple of weeks ago. He designed many of the Hobie things, most famously the Hobie Cat (I always wanted one of those).
Hobie makes some of those pedal-propelled kayaks. I took off one early morning in the gulf, and one of those sit on top pedal deals were taking off nearby, a fishing guy. That guy stayed right there with me, and I can go pretty fast. I was surprised.
Those pedal kayaks are awesome! I've always wanted one, but with salt water and the hassle of taking the pedals in and out when you stop is what stopped me from getting one. We go over a ton of oyster reefs, and the pedals stick way below the kayak, so it's not designed for rocks (at home!) and shallow water over oyster reefs.
I saw the coolest Hobie ever in a store on the coast in Texas. It was a fishing pedal Hobie kayak, with a sail. It had rod holders, perfect rigging, lots of room, and was pretty light all things considered.
We get big winds on the Texas Gulf coast- the wind is always blowing. I thought it would be beyond awesome to sail and/or pedal and save my poor arms. I have little upper body strength and endurance compared to my legs, and would think that would be awesome.
We really just keep ours on shore at our house and turn them upside down. We haul them in and out of the water just about everyday in Texas, and most days in the summer at home so I needed something light and easy. Those pedals require some messing around with, and can't be put in in shallow water.
