Some food to thought here, great video.
I am considering to build my first sailing dinghy and the first thing to decide is if I will use e.g. PVC foam panels as core or plywood which is heavier and may rot in some cases but it has its inherent strength. So I wonder where can I find additional data on how to calculate the required dimensions when various materials are used.

I have a 1966 Ericson 35. I cant find any info on exactly how thick my hull is, but Im hoping its overbuilt. Anyone have knowledge of hull thickness of this type of boat?

All this is a gross generalisation. There is no real structural engineering behind this. It depends on internal, frames, floors, stringers etc. I am feeling you are misleading people. Really you need to study naval architecture before handing out information like this?

Good video but it should be noted that all of these formulas are rough estimates from a very old book. Composite technology has come a long way since Gerr's Boat Strength. These formulas are assuming balsa cores, woven roving/chop strand matting e-glass, and polyester resin with hand layup techniques. Modern composites maximize stiffness and strength with fiber orientation, fiber type, layup process, and lots of different core materials. Good bit of knowledge for the curious but certainly not enough to safely design your own boat!

Well done! You didn't stray into the weeds, which made the basics easy to understand.
BTW, I used you chain+magnet trick to install a new messenger line today – worked like a charm 🙂 Thanks!
