I am now taking a towel in my w/c boats in addition to the sponge that I have historically taken. I found that the towel works better than the sponge for sopping up small amounts of water and cleaning any dirt or fish slime. I also can put it on the floor where I can step on it when getting in the boat with wet feet to sop up that water up before it even wets the floor. It is also a better tool to wipe out any cob webs or give the interior a quick cleaning.
The reason I first took the towel is that I recently started wiping my boat off at the end of my paddling day, so it was already close by. I found this to be a great habit as it only takes a minute or two and my boat is always clean. The towel I take in the boat is about half the size of a bath towel, I can put it on my seat to add some comfort or height or kneel on it in a pinch. I can also put it on the floor in the spot where my paddle blade will be when I set it down in the boat to absorb that water too.
