i use to be a director for the aba , unless they have changed the rules again the rule of the co-angler having the control of the boat half the day is no longer in effect, now with that said remember i said i use to be a director , i am sure what they are now saying a co-angler should have the right to pick spots half of the tournament day.
i personally do not care for this situation because it just seems like the co-angler is competing against the boaters also is bologna . thats why i will fish pro-am or team tournaments only.
the only thing that would make it a alternate to fish these type of formats is if it is the only one around.
as a boater myself it can open up another can of worms on the expenses a boater occurs and really cannot ask the non-boater to pitch in half .
my advise is to go find another tournament format or join a local club .
