I'm looking for a good forward cabin opening hatch as the original although Ive replaced it will interfere with my anchor winch when opened.\
I have no experience with any of these brands as far as hatches go
around about 507 mm square

Hi HG , how is Yaringa?
A year ago I installed...think Vetus, like the large handles on outside,
Large internal seal and holds well the opening angle even when you sailing,
sure or until your bunk is wet.
Needs solid flat base, internal frame is not as solid as outer one.
overall happy with it.
Good or bad I bought a Goiti T60 clearance sale stainless top frame Aluminum base 507x 507 cut out new unused $300
At least it wont hit my anchor winch when its open.
Once this is fitted along with the winch I can paint the decks and non skid surfaces then I can say the that's one job complete 
Ive swapped the old hatch for a Bukh Double V pulley I didn't have to but I will.
So Ill tweak the alternator probably with a sterling power regulator
I wish this guy didn't keep making jobs for me
