It really depends if you are going up or down swell. I've always used RPM, but my best guess is 4 - 6 mph. I like going in and out of the "skud" line. Many times picking up fish on slow turns. 20 foot Rabalo so I find them inside of the commerical boats. I start out at 35-45 feet on one side and 65-85 feet on the other. Pink or green flashers and purple haze hoochies. Green early season pink later. Fish out of Morro Bay
