I'm not familar with them. 48/40 = 1.2 So it needs to be 20 % bigger. This is the benefit of the newer winches being sized in the power ratio. Power ratio is calculated as follows: (Handle Length/Drum Diameter) x Gear Ratio=Power Ratio. Typically these are calculated for a 10" winch handle. For a power ratio 48: This means a pound of handle input, generates 48 lbs of power. An adult is capable of handling loads of 35 lb typically, so the winch can pull 1680 lb of sheet and halyards . Going from 8 to 10" give you 25% more power. 10" to 12" give you exactly 20% more. Although I've never seen a 12 in winch handle, I'd like to have one though. You don't get something for nothing. A longer handle is slower than a shorter handle. So the idea is to size the winch to the load. |

I guess I was wrong... I should have said a couple of inches. I said a few.
