My boat is a 1981 indian river skiff. The boat has no liner, so when running the floor has a good amount of flex. At what point would it be considered too much flex? I'm thinking of adding stringers and a floor to stiffen it up. I would like to leave the center open under the floor to the bildge. Would foam stringers and flooring be really expensive? I'm trying to keep the weight down. Thanks

When is it too much flex?
When it starts to crack.
No cracks yet? Then leave it alone.

Unless you just like to work on boats...

in certain boats its normal. My gheenoe had a ton of flex in it. It always bothered me which is why I got rid of it and built my own boat

No cracks. I would like a floor with drains just to keep everything dry, and not watch the flex while running. Any recommendations on foam for a floor and foam for stringers?

suggestions on foam, nope, I'd just use good plywood and epoxy resin, done right will last forever.
