Do they help with tight turns etc , by reducing or stopping ventilation. Zapcats , arancia irb's etc all seem to turn so fast with lots of power on without ventilating.
The problem with fixed trim on small boats with tiller steer is finding the happy medium between a low trim for good turning and slightly higher trim that gives better speed and cruising.
If a propguard does help then its worth losing a little bit of top to improve turning especially if you are messing about in surf and inshore a lot .
