Re: Any suggestions for putting opening windows on a 23 (Or
The following advice is based on the 1977-85 O'DAY 23, the older model might be easier to find opening ports that will fit the opening as well as the appearance of the boat.
I think it can be done......question is whether it is worth the effort. I doubt that you will find a pair of opening ports that will match the shape and size of the original ports, so a simple swap is not going to be possible. The easiest solution may be to install a vent in the forward hatch, one of the low-profile exhaust vents, either one that draws out the stale air from the cabin by suction created by airflow over the vent or one of the solar-powered models that use a fan to supliment the airflow. Still not cheap at over $100 ea. those vents will still cost less and be easier to install than new ports.
If you still want to put in opening ports, you may find a pair of oval ports that are suitable, it will be less work if they are larger than the original ports so that you end up enlarging the holes in the cabin sides instead of having to fill in around the ports. It may not look "right", but you will have opening ports. If the orginal ports were a bit larger than they are (looking at pics of a 23) You might be able to cutout part of the plexiglass in the original ports to accomodate a pair of small opening ports set into the present ports, not ideal (would require pretty small opening ports!).
To install opening ports that are smaller than the originals will require glassing in the original cut-outs, then cutting out the holes for the new opening ports. That is a big job, best left to a fiberglass expert ,and will take a week or two with the boat "in the shop". The inside may need work as well to do the job correctly. Even after all that.......the boat may look "weird".
