I like the "Magnus" model or "Altus" model on the same Vetus catalog.
Both are about the same price
Magnus even has 4 latches
. If you want to use the open hatch to funnel air down below, choose the Altus which can be set at various opening angles.
The Planus model you show may look a bit more stylish but I'd prefer strength over styling in this case.
I have old Moonlight hatches and they lasted fairly good.
Ok, entertain this idea for a moment:
I think the Planus hatch looks stronger than the framed one for the follow reasons, which are certainly open to debate...
*Much thicker acrylic
to keep it stiff since there is no frame
*No frame to depart from the acrylic
and cause a leak (no rebedding it in the future, maybe replace a gasket is all)
*lower profile means less force from water running over it
*in many years when the acrylic crazes, just buy a new piece, cut to the right size, drill proper holes, and you have a brand new hatch.
I see strength in simplicity.
