- Jan 3, 2012I remember reports that Mariners Hardware was often noted for being a poor operation. Late and non-deliveries, hard to contact, etc.So, I thought I should google Blue Water Hardware and bbb to see what I get. The results were not good. Is Blue Water just a new name? Too bad, I like the product selection/ prices.Scott

They are made by Manship in Taiwan as are the stainless hatches and ports Sabre now uses. Given the the state of the world for small maritime businesses, you should make contact with them before ordering anything. Another nice touch is choosing the inside color.PeteOn Tue, Jan 3, 2012 at 11:26 AM, Ken Jenkins <kjenk3@...> wrote:
Those look very nice, Where did you get them? A quick Google search didn’t turn up any Manship low profile vents.
Also, I agree with vanbeckump that the size restrictions on the opening into the cabin are probably going to make the 4” vents not much better at airflow than the 3”.

I just went with Manship stainless 3" low profile. If I recall, the 4" mounting rings may not fit on the molded Dorade boxes. See attached picture.

Peter and John - Did you go with a 3" or 4" vent as your replacement? If you went with 3", did you consider trying a 4" ? Just trying to understand others' thought process on this one...
