Rules Guy: Does an OB boundary extend past the last stake?

The Rules of Golf are tricky! Thankfully, we’ve got the guru. Our Rules Guy knows the book front to back. Got a question? He’s got all the answers.

Our course has an in-course OB to protect players on an adjacent fairway. About 240 yards out, in said fairway, is the last OB stake. Our pro says the OB extends on a line parallel to the last two OB stakes “indefinitely.” I say OB ends at the last stake. Who’s correct? —Tim Slauter, West Lafayette, Ind.

The answer should be specified by the local rule that creates the boundary; if not, the pro, as the de facto committee, is the decider.

Important to note: Boundaries and markings don’t just “stop,” and when a marking “ends,” typically it is by either tying into another marking or is extended to infinity. Your pro appears to be alluding to the latter, which is generally indicated by a “double-stake” marking, with two stakes placed within a yard of each other.

As to what the marking should be, that depends upon the nature of this internal OB and the geography — and is above our pay grade.

I’ve got a question that has caused a heated debate at my club. If a tee shot on hole No. 1 crosses the out-of-bounds mark, crosses the adjacent street, then enters through the out-of-bounds mark on hole #10 and comes to rest in its fairway, is the ball OB or no? —Mario Polit, via email

Sometimes yes, sometimes no.

Rules Guy isn’t being philosophical or mealy-mouthed; there’s a Model Local Rule (A-5) that would treat a ball that crosses a boundary as out of bounds even if it comes to rest on another part of the course.

Without the Model Local Rule, then if the ball comes to rest somewhere that’s on the course (i.e., in-bounds) it doesn’t matter whether it crossed completely over a boundary or not — the ball is on the course. Which means Rules Guy gets to ask you a question: Does your course have said Model Local Rule in effect?
