Hunter Horizon 23 - afaik were originally fitted with the Houdini hatch (as Tranoma has suggested), pain to fix and my old one leaked from the glass seal, replaced with lewmar but needed minor surgery :-( as a few mm different. Think the old one is still in my lockup lolOn the front of our Hunter Horizon 23 , it leaks a but and needs a replacement seal.
I have not yet seen any writing on it anywhere to give a hint of what make it is.
