The late George Buehler's designs largely brought together heavy, hard-chine, workboat construction techniques with a very traditional wooden boat style. He encouraged the use of plywood for decks and sometimes planking, but otherwise his designs would not have seemed out of place in a working boatyard a century or more ago.
What are some other designers, active or no longer with us, who would be a good source for similar designs? Note that I am not just looking for traditional-looking designs, but specifically heavy, rugged boats with workboat scantlings. Suitability for plywood planking would also be a plus.
Cheers,
Matthew
