Construction Methods — Lapstrake or Clinker
And without any need for added hull rollresistance on a multihull, that benefit would also not be valid in such a case. One interesting development of the original clinker build, was the use of a reversed clinker—where the hull was built starting at the gunwale and the added strakes were overlapped as one built towards the keel.
