I am going to attempt to replace the hatch on my 1979 Hunter 25 with an Ocean 60 flat base hatch as John Bastien suggested in a forum several years ago. I would like to hear from others who have replaced their hatch with the Ocean 60 hatch. Have you had problems with leaks? How has the hatch held up? How was installation? Or has anyone else found another solution. Thanks. I've put this off for several years but this spring I have to changed the hatch since its plastic degradation is getting worse and tends to leak when it rains.
