I really had no idea we actually crossed land 6 times. It didn't seem at all rough like you would expect when a boat slides across the ground. The lake is pretty high right now and certainly higher than it was in the last Google image. Looking at the track overlaid on a topo map, we only touched the water once and spent the rest of the time on dry land.
As a side note, the boat is fifty years old this year. It was built in Santa Barbara, CA back in 1960. It was purchased by my Dad in about 1966. I bought it from him in 1972 and have had it ever since. Dad dubbed it the "Hari Kiri", or "Hairy Carry", depending on how you want to spell it, which still seems a bit overstated. Although it is a lively boat in a good breeze, I wouldn't exactly call it living on the edge.
