Ship building

Going back to my writing about proverbs and sayings that we use, I`ve come up with a thought of where one of them might have come from – or perhaps it`s just my interpretation of where it could have come from. The favourite saying that I mentioned was “Don`t spoil the ship for a ha`pworth of tar” –My theory is that it might go back to biblical time and to Noah building the Ark? After all, it would have been disasterous if Noah had not fully coated the ark with tar (or pitch, as it`s called in the bible) wouldn`t it.
