Roscoe,
I've attached another picture which may help in visualizing the clearance between my dodger and the primary winches. As you can see I have plenty of clearance for the winch handle (Lewmar 8" one touch). Under the dodger for the secondary winches, I do have a clearance problem and can only winch inboard forwards and backwards. This has not been a problem as I normally sail using vang and traveler in combination with the mainsheet.
I do not have a sheet clearance problem with the dodger on the starboard side at all. On the port side, under some circumstances, I get the very slightest of sheet rubs against the dodger fabric, which I have solved with a leather rub strip on the trailing edge of the dodger. I only get the rub on the port side when I use the genoa track car system to move the cars all the way forward (reefed genny or downwind), which tends to move the angle of attack inboard. This is because the port side winch winds to the inboard side while the starboard side winds to the outboard. The change to self tailing winches did exagerate the clerances on both sides due to the slighty larger drums.....given the joys of the self tailers, this was an easy tradeoff to put the leather strip in.
The dodger was in place when I bought the boat. 2 years ago to save some costs, I traded labor with a dockmate who built the same style replacement shown in the pictures for me. If I were to do it all over again, I would probably switch to a California style dodger which would eliminate the sides and front plastic/glass, unless they were specifically snapped into place. That design would seem to eliminate the trade-offs I have seen.
