"If the water is too shallow to safely use a Mirage Drive, it's also too shallow to safely use a rudder." Interesting. I've never used a rudder, I didn't realize it stuck down that far. I really appreciate the time you've taken to share your knowledge, pmmpete.
Certainly fins stick down further than a rudder. But if you are in moving water which is shallow enough that you could hit your Mirage Drive's fins on a rock or a gravel bar, you are also at risk of hitting your rudder on a rock or a gravel bar.
When you're pedaling a Mirage Drive around in a lake, if you enter a shallow area you can flutter the fins of your Mirage Drive up against the bottom of your kayak, and you will usually have plenty of time to pull up your rudder before it hits bottom. In moving water, particularly if the water is muddy, it may be difficult to tell how deep the water is in general, and it may be difficult to tell that a rock or other obstruction is sticking up off the bottom. But a sudden bang, crunch, and jolt as your kayak gets swept over an underwater obstruction or a shoaling bottom, busting your Mirage Drive and/or your rudder, will tell you that you should not have been using those pieces of equipment. This kind of mistake is an expensive mistake, and can screw up your day. I don't use a Mirage Drive and rudder in moving water unless the water is reliably deeper than 3 feet. If the river is likely to get any shallower, I use a paddle kayak, not a Mirage Drive kayak.
