You might often run at a constant rpm but if you put a torquemeter on your shaft you would see that the power varied widely.
A small light boat is greatly effected by wind, waves, steering drag, changing trim as even a single person moves fore or aft, etc. so what appears on a tach as "steady state" is anything but.
Which is one of the reasons I think this thread is as meaningless as soothsaying performance based on a photo of the rudder and propeller or a brokerage pic of the boat at a dock. I guess it is possible that there are people who can look at a photo on the internet and develop performance charts along with a stability book, but I ain't one and I'm not about to pretend either ... I will leave that to the usual suspects.
