Hello.I own a swing keel H22 and am having difficulty locating a supplier for the following parts.The V berth cabin has a small hatch on each side. These hatches/port holes are held closed by 3 finger knobs on each hatch. I have 3 of the 6 that should be replaced as they are broken. This means that effective seal from the weather is impossible.The other item is the Mansfield chemical toilet. The original has to be replaced but I cannot get a unit identical which I would prefer. It is 13 inches high.I have emailed Mike Thomas at Hunter Marine as suggested by our dealer here in the UK but not received a reply. Can any owner in the US help with advice on how or where I can get replacementsBest RegardsJohn Bond
