I have a Bruce Roberts 53ft with a long fin keel, 25 ton displacement, 3
blade fixed prop and an 80hp engine. I find that if I use short bursts of
astern (rather than continuous) The rudder has a bigger say in the
proceedings and I suffer much less prop walk. Once she is moving astern, the
prop is maintaining boat speed and no longer trying to accelerate, it almost
feel like I have control
