I don't own a boat now but had one for around 30yrs in our family.I go out with 7 different buddies.Some of them are just casual fishermen.Boat not really set up to fish or have the proper gear.I show them how to properly set up their boat and how to use electronics better.Hoping it will help them catch more when they fish on their own.But they inevitably don't do what will help them catch more for one reason or another.But they have gotten alot better over the years.
Another great way to improve your success is to go out with a charter.They can teach you a lot on how to troll properly.Several are regularly on this website.Capt Sam,Juls and Capt Eric with the pirate clipper.They could teach you a lot on setup and technique.If you go yearly with them,and get to know them,they may even help you with location of current bite.I've gotten to know several charters fishing with them over the years and they often help me with location of current bite.
