For sailing, the chop off rudder is gonna be still good enought?
I just bought a revo 16 and order the ama kit and star sail supernova and gt combo. I will use the kayak in shallow water
To answer your question, I might re-think the rudder chop, or at least make it one inch longer (or about the same length as the small rudder). The reason is this:
When sailing, you want a balanced helm or a mild weather helm. The more weather helm you have, the greater demands on your rudder to control the boat. You get weather helm when the center of pressure (CP) on your sail is aft of the boat's center of lateral resistance (CLR). This becomes a potential issue when sailing close hauled or when tacking. With the Hobie sail, the CP is aft of the CLR, providing acceptible weather helm (with the large rudder). Your Star sail, being larger, the CP will be further aft of the CLR. I've never tried the sail, but based on others experiences, this doesn't seem to be a problem for the sailing rudder, but I would be cautious about cutting it down until you see how well it handles your sail.

You may have seen this discussion on the use of skeglets with the Revo 16 (AKA Adventure):

actual use of skeglets would seem to contradict fusioneng's "reasoning". Stringy also shows how to attach them.

As part of my testing I did a 360degree turn while pedaling.
On the water it felt like I turned almost in a boat length. Here is what my GPS recorded. That is a 30’ yacht on the left.
It is possible that the reason this works is because the skeglets do not protrude below the keel line on the Revo 16. When moving forward, they help stabilize the stern, but when a turn is made, they are significantly masked by the keel, therefore minimally interfering with the rudder action. If you were to have any weather helm problems, these could be a nice remedy. They probably won't do much for you in the tacking department though. I recommend waiting on these until you see how your rudder performs.
Regarding sailing in skinny waters, it's difficult to sail upwind without some sort of bilge board which needs to project below the boat. Using Turbofins or your daggerboard will require a greater minimum depth than when not sailing. In this regard, your sailing rudder (untrimmed) will require less depth than either of the other two. Sailing downwind in skinny waters you can pretty much rotate fins and daggerboard up against the hull without a problem.
