along these lines.....do the wing keels (small keel-like runners 8-10" tall located about 1/2 way between true keel and chine) that some sailboats have, work well at sea? Would they be a worthwhile addition to a trawler? I have seen two trawlers with them but couldn't find owners to inquire.
I'm sure that isn't the term for them, and I'm not asking about a true wing-keel i.e. the horizontal foil on the bottom of sailboat keels.
Kind of like what is seen in post 98 in the link below. Maybe not as big though, that size may be what is required to gain appreciable effects.
