Fishing from the backseat has always been construed as a handicap. The phrase "backseated" illustrates the degree to which we think that disadvantage exists. The boater, perched on the front deck for the entire day, gets the good water, best casts, and the most fish. Now, take a veteran boater and relinquish him to the realm of the backseater. Boaters will have many more conflicts when paired together than a boater - nonboater combination ever dreamed of having. Each being very set in the way they fish and handle their boats can lead to enormous disagreements (whether voiced or withheld).
It is impossible to say that everyone who ever pairs up will get along, fish the same, and compliment each other's style. Sure, on occasion the fishing that is being done will be equally approved of, and boat position may not be a big factor, but what about those times when its not all roses?
As a boater for nearly twenty-five years I have my own way of doing everything from setting up to fish a laydown tree to launching the boat. When, on the rare occasion, I fish as a backseater I become the classic "Backseat Boater". Just as the backseat driver can quickly become a pain in the backside,
I am sure that there are several anglers out there who have felt the same way about me. So what do you do about it? Most of the time I just keep quiet, politely mentioning that I have no casts or that I am fishing too far away. Now, I usually follow up with a "but its your boat", realizing that it is their boat and it should be their style fishing for the most part. I suppose the largest problem with placing a frontseater in the back is the loss of control, often a total loss of control over anything. Throughout the day you silently criticize your partner, his approach, choice of location, etc. But, it is his boat.
Discussing methods and locations is a great way to try and get onto the same page. Also, if you, as the backseater, know of a place or method that would likely be more productive than what you are currently doing its not out of line to suggest it - but not make the decision to go and do it.
The lack of control over the situation can lead to frustration, especially under circumstances where the boater has chosen a style that is not your strong suit, like maybe flipping or running a deep diving crankbait. On the other hand there are advantages to being up on that rear deck. To a boater who is used to running the trolling motor and fighting wind or current all day is sometimes feels like a vacation. The stress of "running" the boat is removed and you can concentrate more on actually fishing. So, when you end up fishing behind another boater just remember it is his boat. Afford him every courtesy that you would want your partners to give you in your own boat. Make suggestions but don't make demands. Try to start off on the same page as each other. Getting as much out up front will go a long way towards an enjoyable and productive day fishing as a backseat boater. And, don't forget to split those expenses just like your backender does with you.
