I am embarassed to even ask this but here goes

... Our Sailboat is a 40 year old
Ketch with what appears to be solid
wood (teak)
flooring through out the
cabin, it is not a laminet. There are grooves (1/8" maybe 3/16") cut to make it appear to be 2" wide planks.
Where would the holly be? I have been
boating for 40 years and have always used the phrase
Teak & Holly and did not really no what it was. I am now preparing to refinish the sole and this whole holly thing has come up.. I just
assumed (I know, I know) I had
teak and holly, maybe I dont??? Please dont laugh, just a nice gentle answer. Thanks.
