Troll, Trim tabs and a hydrofoil are an option. If I'm buying a boat and choose to add them to my boat order and negotiate it with the dealer that is fine. I don't see how you can demand that a boat manufacturer provide them as standard equipment. The boats handle fine without Trim Tabs, but many have reported that they like the handling better after adding trim tabs. So they are available as an option. That seems good enough to me.
