This was my first year as a co-angler. I fished about 5 tournaments and learned some valuable lessons which might help someone else.
1 - BOBA's (Back of Boat Anglers) need to be versatile. Even if you talk to your boater things change the day of the tournament. You need to have a little bit of everything in your tacklebox just in case. There is a fine line here too so be careful not to overwhelm yourself with choices. Fish things you have confidence in.
2 - Fish your fish. When you get to your spot make your own assessment about the conditions, depth etc. Fish what you think will catch fish in those conditions. Be persistent.
3 - Observe your boater. If your boater is killing them on a particular lure then it's ok to adjust to that lure and catch some behind them. In most cases however it may be a complimentary lure which may help you catch fish better. Example: Boater killing them on a Texas Rigged Craw. Follow up with a more "finesse" style texas riged senko, trick work , or finesse worm.
4 - Ike's "Never give up". I fished one tournament which started in 20 degree weather in the AM. We knew the bite was going to be tough. I ended up with only 2 bites for the day. My boater caught at least 6 - 8 keepers that day. I was frustrated and disappointed that I couldn't fill my limit and was really hard on myself about it. Well ... I get to the weigh in and place 6th with my 2 fish. Several boaters came in with no fish. It's truly all relative.
