Fishing like life moves on.
The beauty of fishing for me, John, is that my fishing life 'moves on' only at the pace I decide. When I'm fishing, I inhabit my own little world and I fill it with what gives me satisfaction. Catching carp with the aid of a bait boat would give me so little satisfaction that I wouldn't ever consider using one - at least on any water I've fished in the UK.
The difference between a bait boat and a better reel is fundamental. One improves the function of a vital angling component, the other completely does away with a core angling skill. These things are entirely subjective and personal, of course, as is angling itself, and provided the rules and spirit of our sport are upheld, what you include in your angling world is your own business.
For the record, the personal satisfaction I get from my angling is strongly connected to the merit of my captures. Bait boats replace the skill of the cast and therefore reduce the merit. This can't be argued against. Casting requires more skill than dropping your rig with a boat - fact.
I guess we all have our levels and standards, and what a complicated mix they can be. There's no room in my 'mix' for a bait boat, that's all.
All the best.
