We use a Walker Bay 8' rigid and we have the inflatable "water wings" for it as well. We use oars and row it, which on a hard shell dinghy like the WB8 works quite well. The "wings" can deflate easily, and it will fit on the bow of our

, though so far we have just been towing it. It tows quite nicely, though our only experience is at less than

hullspeed since our boat only came with a 20hp. We've towed it through some fairly big chop now (20-25mph steady wind down a long lake last weekend) and it handles well. It creates far less drag then the previous 9' inflatable Sea Eagle dinghy we've since sold.
DO NOT, however, remove the plastic bit in the daggerboard trunk - I removed ours since I fancied the idea of getting the sail kit and zipping around protected bays teaching my kids to sail... what we've realized is that packing all the extra gear is a pain (so we have hardly used it sailing), and now the boat "leaks" around the daggerboard trunk/seat interface when all 4 of us (450+ lbs) are in the boat... it's rated at 380 lbs, but it floats without the water wings in the water, and they just add to the stability. I've since tried to seal around the trunk, which has worked to some degree. But while pounding back through the chop last weekend, water was obviously shooting up through the open trunk occasionally, because we had about 1" of water on the floor once we got back to our mooring 6 hours later.
Our secondary "dinghy" is a convertible kayak/SUP by Ocean Kayak (Nalu), which we tow on a second boyant rope from the opposite cleat. This one doesn't tow quite as nice, but it is a lot of fun paddling around at anchor
