Craig, that's true. It certainly would be a good fix. In the end, it came down to considering the pros and cons of:

1) The domino effect. 2" here may not seem like much but what if I'm missing something?
2) I'd have a hole in the roof if I kept the slide to the plans.
3) I'd lose 2" of the companionway opening if I re-fit the slide.

It turns out it's not that bad of a curve. It's curing now, with tack welds and five clamps across the opening. Adding a little bit of timber to finish the butt block aft helped round the new piece and will help hold it in place as it cures. It's not perfect. As expected, there are certain areas slightly off. However, it's not so much that a little epoxy won't fix. I'm encouraged but will know tonight when I remove the clamps and can fair the rest of it.

Glad you got this all worked out. Reading all the posts has taught me a lot about how the companionway slide works.

Has anyone answered this question? Or are we the only two PS builders who wonder?

Thanks for your thoughts,

My build is now long past the point it was when I asked the question so my recollection isn't fresh. However, I'm certain that I measured from the aft side of the aft cabin wall and that worked out.

The 20.5" measurement between the aft cabin wall and companionway edge of the cabin roof is to be made along the center-line, not the port and starboard companionway edges, correct?

Thanks,
Mark

The companionway opening runs parallel with the rear cabin wall so it should be the same 20.5" on both edges and the center.
I don't think the precise length of the opening is critical provided the sliding hatch is slightly longer (or at least not shorter) than the opening to ensure the companionway keeps water out.

Hi,

For the geometry folks out there, because the rear cabin bulkhead has a curved upper surface and the whole bulkhead slants forward, measuring the fore-and-aft opening along the boat's centerline (from the temporary bulkhead piece still tabbed into the opening) will be a tad shorter than if this opening is measured along the outboard edges.

In answer to my own question above, Page 11 of the plans specifies the 20.5" measurement (pg. 171, gluing the cabin roof) to be made along the outboard edges of the companionway opening. Regardless, as Wayne notes above, the sliding hatch must be long enough to keep water out.

Always good to study the plans and manual together! :-)

All the best,
Mark
