Portholes

A small marine window, mainly round or oval in shape, the hull porthole allows fresh air (sash type) & light to enter the boat, eliminate humidity on board and provide a view to the outside. It's usually located in the below deck areas.

SEIMI is able to offer you standard or custom-made portholes, designed to withstand the marine environment and adapted for professional and pleasure boats. Less used these last years, the round porthole is a type of marine window that is coming back in fashion.
