Dear Glenn:
Thanks for your participation on the forum. I've been reading and learning!
I thought to post to you a question of mine -- and others as has recently come up on the Cherubini Hunter forum. Here is what I posted:
"When I engage reverse with the boat stopped, the prop wash (as observed from the surface) exits the boat almost perpendicular to the fore/aft axis. So the first motion of the boat is that the aft swings hard to port before any backward motion is acheived. Most people say (without guarantee) that a 3 blade prop will help. But I don't know yet. I'm waiting until my next haulout to install one. The existing prop 2 blade prop I think is original issue and has minor pitting in a few spots, so probably time to change out anyway. It's diameter is 16". Clearance between the hull and the prop is only 1.5". Less than normal. This may account for some of the prop walk issues. Changing to a 3 blade can be smaller diameter = more blade/hull clearance. Yes, I know that one can learn to use prop walk to good advantage. But in my boat's case, its too much of a good thing!"
I've read that some boats go in reverse better/worse than the norm. What are the design considerations that affect this? Attached is an aft section photo of my H36C. Thanks for your comments.
