We are looking at purchasing a Oasis Tandem but one thing that is holding me back a little is I am wondering what if anything we are giving up when we don't feel like pedaling and we want to remove the Mirage drives and just paddle old school. How well do the Mirage specific hulls perform? We have a few shallower rivers here where I think the drive depth could be a real detriment.
The Mirage Drive kayaks don't have skegs so they don't really track well, especially with the rudder up compared with comparable skeg kayaks. But that's also one of the reasons they turn so well. With the rudder down, it acts as a skeg and greatly improves tracking on all the models. Cut the tip off the large rudder and you have an excellent shallow water rudder. Learn how to "flutter" kick and you can use the Drives in about one foot in depth.
Now if some smarty pants could devise a system to switch from hand to foot steering as required, that would be a true hybrid
