It is not so much the boat as it is the boat operator. I own and use a small sled with a 40hp/28hp at the pump outboard. I use it to go
places that I could not fish from the bank or do not have time to find someone to float with, in my drift boat. I ALWAYS give the bankie and the driftboat the right of way. I don't blast through holes. I get pissed off like the rest of you when I am working my drift boat in to a hole and some a-hole races into it to fish. I can not see any reason for large sleds to be on the upper rivers. We floated Schafers down to White bridge on the Nooch last week. As I arrive at prime water about 2 miles up Carter ck I see a sled.
Yea, I am angry,But it is operator ignorance more than the sled itself. If they want to ban large sleds in the upper areas that OK, if they wanted to band all sleds in the upper area that is ok too.
The point is this, you don't ban cars on the highways because people speed or drive in a reckless manner. There are always going to be a-holes, in sleds, in driftboats or on the bank.

One other point, I don't know how many times a sled has gone through a hole I have been fishing and with in a minute I hook a fish.
