What Is Joist "Sistering"?

Sistering a joist simply means attaching more material to the side of
the joist. This can mean a new joist of the same size and length is
screwed or nailed firmly to the old joist, or it can be a smaller
structural member. Sistering could also involve sandwiching the old
joist with new material on both sides. Typically this involves framing
lumber, but it could involve engineered lumber, structural steel or
formed steel joists that are made of heavy gauge sheet metal.

That may be true of joists but not boat frames.

BTW to call somebody a "house carpenter" is is considered an insult
among boatbuilders.
