tracking problem under power

I just replaced my two blade fixed prop with a three blade max-prop,
and had the rudder rebuilt, which was de-laminating. I took it out
this weekend for the first time, and under full throttle it tracked
consistently to the right, and required about five degrees of
correction by applying constant pressure on the tiller to compensate.

Can anyone offer any clues as to the possible cause, or suggestions
for a remedy?

Thanks,

Jon–

My BCC, “Devon” ex-Bucephalus, also has a Max-prop. I’ve only owned
the boat for six months and have not powered that much (and, of
course, never without the Max-prop). So I can’t compare it with a
two-bladed prop. But I notice exactly the phenomenon. The boat
tends to steer to starboard naturally, particularly as you increase
the RPM. You therefore have to compensate by pulling the tiller to
starboard. I just thought that it was natural. I don’t think that
any sailboat steers straight. Right? I don’t think that it’s a
problem. That’s my two cents. Good luck!
