I have one of the 2004 models, hull number 25, which has the smaller skeg. The skeg is offset to port to allow more space in the rear compartment, well thats the idea anyway. I feel that the boat suffers as a result of the skeg being shadowed by the hull, the Expedition is quite prone to weathercocking and needs the skeg to maintain its course, the 2005 model has a HUGE skeg, so big that the skeg box on the LV actually penetrates the deck! The 2005 can obviously create more stable tracking due to the bigger skeg, so I would assume it handles better, but I haven't paddled one.
