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 .

Having had the pleasure of racing a Thundercat in Portugal that doesn't have a guard, I can tell you that although they play havoc on your forearm muscles, they do not suffer from ventilation at all unless landing a jump from miles up in the air with no forward speed on full throttle!

Cheers Cookee
i guess i shall have to play with my set up a bit more then .
What i was thinking was that a boat with power to wieght ratio such as a zapcat would maybe ventilate easily if too much power was used in a tight turn , rather like a powerful car would spin the wheels easier . Lateral thinking
