We're in the same boat
I think ERABBIT is right, although I'd love to see some more opinions. We get set up (riggers & planer boards) and get our speed to about 2.2 gps. Waves (haven't had flat day yet this season) will vary that up or down by about .2 so we'll bounce between 2.0 & 2.4. If we're marking fish, we'll goose it a bit every once in a while trying to dial in a speed they like, then a bait they like. When you get to the end of your troll and reverse, you have to start all over again because of the current.
We're catching fish but I'd say at maybe half the rate of an experienced boat with all the gear. I'm hoping that improves considerably when we can afford to add down speed.
