I'm not sure of what safety regulations your talking about.. ABYC, USCG, ??

The boat designs that I have dealt with never got down to such detail. These
element are left to the builder wisdom and discretion.. Even if your talking
about fastener types or material, that is also left to the builder.

Load and passenger capacity plate? Nah! not applicable in a 38 ft boat.
