Re: new trick for removing head hoses!
Boil some water and pour it on the end you are trying to get off. It will soften it and make it easier to remove.
But after having to replumb the head hose on the high seas on a passage from St. Martin to the Bahamas I will never again do it unless I have to. I am all for Mark's suggestion to have the dockyard guys do it. I will even pay US prices.
