Hi Gene,
I've heard back from Catalina Tech Support but so far they weren't able to provide dimensions. I was able to find a thread on here mentioning the dimensions for a 'new design' dinette table being 32" x 19" but upon measuring the distance between the dinette seats 24 1/4" seems to be a fit (could go 24" but not sure if I'd want that much wiggle room. Athwartships, 40" looks like a maximum.
BTW - I just wanted to say how much I enjoy your Youtube videos and responses on here. From another thread, I just set up a Coleman water jug as you had shown previously and am working on the bow eye bolt reinforcement.
Thanks,
Chip
