I just read a statement by Uffa Fox that the main boom length:mast height

In that his opinion was that racing craft should indicate best cruising
design, I assume this assertion applied to yachts in general.

Does anyone know if this measurement for the mast height would be assumed
from deck level or total mast height ?

I'd take it as height of sail, personally.

Still, rules of thumb go in and out of style.

For what's currently in vogue, I'd look at recent go-fast boats built
under rules with few if any restrictions. Since they're faster than
their predecessors, I'd consider them the current state of the art.
