Wrong

For example (as Jeff said) a frame in a wooden boat can be sistered
but the new frame isn't attached to the old one.

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.
