Is the mirage drive faster than paddling?
She would typically have to get on the boat from a dock. Their dock is in a marsh creek. How will this go?
The boat itself probably draws about 2 or 3 inches. You can use the mirage drive in shallow water by doing partial pedal strokes, keeping the fins close to the boat. It works very well, and in fact is part of the benefit to the design.
Is the mirage drive faster then paddling? Yes. But that's if you compare paddling your Adventure, or using the mirage drive. As a former traditional kayaker, I have to say that speed is a tough one to measure. Here's what I've noticed. (keeping in mind that I have quite strong legs and used to be a high level amateur athlete)
I can out sprint just about any kayak that I come up against in the water. The boat accelerates very well, and with properly tuned turbo fins, is quite a fast boat. The catch is that the mirage drive, the rudder, and the design of the hull work against you when it comes to speed because they all create much more drag then a traditional, quality sea kayak. Sea kayakers in sleek traditional kayaks have very little drag, and they can take very LONG powerful strokes. The mirage drive, by design, can only give very efficient, but short strokes. Over the course of a long day of paddling, the sea kayaker will probably be a little bit faster. Over a sprint, I've proven that I can be faster. (I can't explain why the Tandem Island above wasn't faster, I can only speak for my experience, and it comes against, experienced and fit kayakers in sleek boats)
But there's another side to the equation. While the sea kayaker might be faster in an hour long paddle, the Mirage drive gives you more torque, or pulling power. My experience is that when you load up a Mirage Drive boat, or a traditional paddle boat, the mirage drive pedaler doesn't experience as much weight as a traditional paddler. The mirage drive pulls effortlessly, even if you load up the boat. That's why you see those promotional videos of the Hobie pulling the tandem traditional kayak. The pulling power of the Mirage Drive is excellent. So if you were to tour with two full boats, one mirage drive, and one traditional, both loaded up with weight, I think the speed may even out.
The final difference when it comes to speed, the mirage drive kayaker will ALWAYS be at his or her most efficient. The traditional kayaker won't. It takes experience to get a smooth and efficient stroke, and then it takes skill and fitness to maintain that perfect stroke all day long. The mirage drive boats are efficient every time, every pedal. So that also contributes to good speed.
So is it faster? It feels fast, and it's probably as fast as any other similarly designed boat that offers that much stability. Is it the fastest kayak that you can buy? No.
(wow, that was a long story eh!)
As far as launching in the marsh area. A lot of people leave their drives in for that type of launch. I'm a big fan of pulling the drive when it is at risk of contacting crap, and paddling instead. It can't hurt to pull it, but it will always depend on you comfort level with the debris around you.
