hunter 146 Keuka Lake NY/ Jersey Shore
Hello all! Bought my 146 last year and with alot of advice from here, got her all fixed up and out on the water last summer. Anyway, whilst scrolling thru the replacement parts here, I noticed that
a black plastic mast step was available. My 146 didn't come with this (at least it wasn't include in the sale). Is it important? and what is it's function? Not very expensive part...so should I just.
Just curious
