I am always surprised when I discover some one has read my blog, but last weeks reader left a comment which made me realise how little I think about an audience. The question was "why is a stiffer boat better" and "some flex would be a good thing". That's correct, some flex is a good thing. A flexible structure will absorb impact loading softening a blow. My concern, however, is that localised impact loading from the trailer could be delaminating my bottom planks. A stiffer bottom and more rigid hull will help distribute the impact load across a broader area instead of the immediate impact zone.
It kind of makes sense to me and I think it will help my boat deal with rough conditions. I hope it makes sense to my reader. I don't have an animation prepared, but this is a real simulation from the "MechanicalLaboratory" you tube channel explains torsional stresses better than I can.
Your reader thanks you.
