I recently redid all the interior in the boat and now its time for the flooring to go back in. Instead of carpet I was throwing ideas around of an alternative flooring and wanted to see what others have done/seen out there. Would rhino lining like for a truck bed work? Easy cleaning and low maintenance but maybe rough on the feet? Id like to hear opinions before settling with one...

I would think the black rhino liner will be hot as hell in the summer sun and rough on the feet

I think there's a reason you see so much carpet. I wouldn't want to be walking on rino lining with bare feet all day. I think my kids would be bleeding from scraped knees and toes. I'll be redoing the interior of mine this spring also and it will be getting new carpet. my .02

Try snap in marine carpet. Have the edges bound. Take it out, powerwash it, put it back in...
Although I put laminated hardwood floors in my cruiser, polyurethaned them, and they look as good as they did 10 years ago.

Use Lonseal or Pirelli flooring

they make a product similar to the proctect used on garage floors. Easier on the feet and stays cool. Also slip resisent
