A lot of users think the Revolution series tracks too poorly to paddle. This can be true. There is no skeg to speak of -- this is so rudder response can be enhanced. On the other hand, the Revos can be easily set up to track flawlessly. Below is an example -- a Revo 11 paddled for over 1 1/2 hours without once pausing to adjust the rudder. This includes all turns shown:
The key is to use the rudder as a substitute skeg. In order to do that successfully, the rudder doesn't move, once set. Since the boats expand and contract with temperature, rudder lines can get slack. This is easily correctly by removing any slack at the starboard rudder connection with a Phillips head screwdriver. With the rudder locked down and straight, all slack should be removed and a little tension introduced. If the rudder handle still moves freely, a small piece of nylon strap (or comparable) can be slipped under the rudder handle to keep it from moving without input. All turns can then be handled by the paddle and edging (tilting the boat slightly away from the turn). The Revo 11 and 13 respond well to edging, the Revo 16 less so. Likewise, the Revo 11 responds to turns best because of its short length.
Any of the Hobie rudders work, but the large rudder offers better control IMO. My all-time favorite is this customized large rudder. It is clipped shorter than the small rudder, has outstanding shallow water capabilities and retains excellent authority with relatively low drag.
Not only can the Revo 11 be made to track beautifully, you may notice it are pretty fast, even when paddling. It has a "sweet spot" between 4.0 and 4.3MPH where it really moves efficiently. Personally, I think this hull is the fastest 11' plastic boat on the market, bar none. I'm not a great paddler, but cruising at 4.3 was not difficult. If you do this, a suggestion (if you're not using the Mirage Drive) -- tape over the Drive well (plastic packing tape works great), leave a slit for drainage, and install the drivewell plug to prevent sloshing. Happy paddling!
