I have a 26ft cabin cruiser. I think you were in the ballpark at 1.3 to 1.8 Keep in mind that alot of the guys posting here have 2 lines for every man in the water and they have their speed all worked out. They also are better at preventing tangles.lol choosing colors, telling each other whats working and whats not. I had the same problem first couple times out, there are kinks to work out. I dont know why you couldnt add more bags, call the guy at amish outfitters and tell him your situation, they have dealt with many different boats and can tell you what others achieved with bigger or more bags. Not to mention our boats arent ideal fishing boats and if your like me your trying to drive and tell the crew how to do something you read about on the internet. Good luck, Ill be up in a couple weeks to try my luck again.
