I doubt there is much difference in towing
a 9' vs an 11' dinghy.My experience has been that the 11' dinghy will hold my wife and 3 kids reasonably comfortably, wheras the 9' boat didn't seem to have nearly as much space.Remember that the interior volume is much shorter than 11' (probably 8.5') because of the tubes. On a 9' dinghy, that interior length becomes 6.5 feet. then subtract another foot if you have a gas can in the back.Then put 5 people in it, add some waves, a couple of wakes from powerboats passing nearby, and your wife will ride in it once. Subtract the kids, and you're fine.Honestly, towing the dinghy is practically effortless in relatively calm water. Where I have run into trouble is in waves (2-4 feet, not big stuff), where the dinghy hits waves at a different time/spacing than the sailboat, causing it to jerk at the tether. I may need to haul the front of the dinghy up out of the water and tie it onto the stern rail or something to fix this problem, but I haven't tried that, yet.I woudl suggest taking the whole family to the store to sit in one of the boats. Assume the rowing position in a 9' dinghy and see if you can actually row it without your elbows and knees bashing your kids in the head.Good luck.
