RE: First shortboard
Another question -
Will this be your gorge board, or do you live and sail in another location, and just want to use the board on a trip to the gorge?
SteveC's questions need to be answered to give a good response. As he said, your board is pretty big for normal gorge conditions, assuming you are experienced and have your water starts down.
Most gorge sailors are on boards from 70-100 liters.
