Response from Nauticat:
Unfortunately exactly the same as you have, are no longer available, but do not worry, the portlights we use today are available and I believe the one used on NC-331 is the same size as yours are.
Attached you will find pictures showing the portlight we use.
If you could give me the outside dimensions of the portlights you have, or even better the opening dimensions on the hull, then we could check,
does this one match the opening.
best regards
