The 1980 34 has “go fast” windows as I recall. By contrast, the 1978 34 had the old screwed on oval style windows (like the C&C 33-1). The openings on the older oval windows are slightly smaller than Lewmar No. 1 opening ports, allowing for this upgrade. It would be much more difficult with the newer style window.

Did you mount them into existing solid lean windows or retrofit in some way. I’d love to do something like this on my 1980 34 to increase airflow Dean BarraWind Halifax, NS On Jun 21, 2025, at 12:42 PM, Matthew Wolford via CnC-List <cnc-list@cnc-list.com <mailto:cnc-list@cnc-list.com> > wrote: P.S. If you have the old-style C&C windows, you may want to consider Lewmar opening ports as an upgrade. It made a huge difference on my 34 reducing the heat down below on hot days.
