Trotting is the game , chub are the target, and you're confident there's a chance of a few in the area.
Start loose feeding maggots as soon as you arrive. The perfect situation is to be able to loose feed accurately by hand or else with a catapult. Around half a pouch each time with the aim that those maggots will end up in a general target area. That target area is where you want them to compete for the food and gives you enough space to play and land them without continually spooking them.
Continue feeding accurately as you set up, have a coffee, have a chat (with yourself if no-one else around). That should take care of 15mins/20mins.
8grm/10grm loafer bulk shotted to start with, #18/#20 hook single or double maggot.
One more pouch goes out and your first trot is set to less than full depth and follows behind that loose feed. Feed in that way accurately every trot. Continue with that religiously until you feel it's not working!

It works more often than not on my favourite parts of the Dorset Stour but often requires playing around with depth and shotting during the process.
After the first obvious bite or lost/landed fish increase loose feeding to the same place twice each trot, once as usual, and again at the end of the trot.
Keep that feed going in accurately and often. If the odd chub turns up every now and then, give the swim regular rests for a few minutes but keep the feed going in.
If you sense they're there and ready for it.... attack, attack, attack
