I would always chose a well designed and well built design over an overbuilt one.
Overbuilding (too much meat) does NOT guarantee any extra safety
. In fact, it is a proof of the builder
not knowing that it is in the choice of materials and in proper use of materials, techniques and skills that extra gains are made.
In fact, overbuilding may add to structure's early aging and its premature failure.
So I stand by my well designed&built concept
I also accept the fact that in vast majority of cases a slightly overbuilt element may add nothing or very little to the risks, as well as that it may actually limit some risks, in some cases.
Of the dozen or so books
on boat design I have read, NONE suggested overbuilding as a means towards any end.
I think my favourite passages that relate to this subject are in Offshore
Cruising Encyclopedia where Steve Dashew talks on loads and how they are addressed in hulls, rigs and appendages. I believe this is a must read and an eye opener to anybody arguing for overbuilding.
