Our current dog wasn't, you're correct. He wasn't born until 2004. The dog we had then (same breed) was an expert on salmon trolling and halibut fishing but he didn't know squat about running a boat and had no interest whatsoever when we bought the Grand Banks cabin cruiser. It wasn't a fishing boat, so he couldn't have cared less about it.

A left hand propeller should walk the stern to port.
It acts just as though it is walking on the ocean floor.

Nevertheless, this left-handed propellered boat requires a three-degree port rudder to maintain a straight course while going forward, and the stern turns to starboard in reverse.

Depends on whether you're talking forward or reverse, bow or stern.

Maybe I misunderstood, I thought you had had your boat for a bit before this lesson and at least knew which direction each of your shafts turned when in forward or reverse.

That makes sense.
A 3 degree port rudder is in effect telling your stern to move to starboard to compensate for a port propwalk.
And yes, your stern should creep to starboard in reverse.

My wife and I did know which direction the shafts turned--- we learned that during the sea trial in SFO Bay before buying the boat because we looked specifically to find out. What we didn't know was what this "hand" business is and what it relates to as we'd never even heard the term before. And if you don't know what a term relates to, any reasonable-sounding explanation can be plausible as it was in this case.

It's just like P-factor that student pilots learn except that the prop is on the other end of the vessel.

Depends on whether you're talking pusher or puller.

Maybe you should have asked your dog.

Sorry, I couldn't help myself.

[QUOTE=Marin;360378]Okay, did a bit of research on the Michigan Wheel website (our props are Michigans) and it turns out that I was in fact taught incorrectly how to determine left and right-hand props. Can't remember who taught me that palm-on-the-blade method, but it was someone who should have known better (surveyor, perhaps?).


Good golly folks -The reason props are called "screws" is because they do the same thing screwing into water as a right hand or left hand thread on a bolt does for screwing into its left hand or right hand threaded nut. It's pretty easy to figure out (by looking at it) which way the bolt's thread screws into a nut as well as which way a prop screws into water.
