DW you’re right in the ballpark. According to my Precision Trolling app it’s 10-12 feet per ounce depending on speed. As far as Ashtabula goes, my buddy went out on the 4th and 5th. Headed to 01 line and 50 west. Crushed them in 2hrs with dipseys and spoons in 2hrs. 3 man limit. Went to the same spot on the 5th and they were gone! So the schools are moving. He had to head East of the harbor to find them the second day. Not as many big fish the second day either. He still limited out but took a few more hours. In Geneva we were hitting a school and then spotty marks. Other boats on the radio were saying the same thing. Guys be ready to make moves if you’re not catching or marking fish.
