My
boat came with nice curtains. I saw another
boat of the same model without, and took mine down. The boat without looked far more open and uncluttered.
I do have external covers I use to protect windows, reduce heat, and sometimes for privacy.
The curtains were installed with the
Sailrite tracks. They worked well and were very compact. I left them up as they are not noticable and we could always change our minds.
