Every boat 21' and longer I have tabs mounted on. They are excellent for load balancing, and helping to get a smoother, dryer ride. They recess nearly flat. Tabs do not prevent you from going anywhere you want to go, by the time you may have bumped a tab on something, your hull has already hit hit.
