SA, im really liking that Corbin 39....why are you disliking the "double ender".
I have heard they are not popular (doesn't mean it is bad in my books....I sail a junk rig

)
I would of thought less chance of broaching, when running in large seas, im just guessing as I don't know.
My dislike would be what looks like not full headroom inside, & that port-side high berth (probably only good for the cat!), I would turn the long seat in the wheelhouse into a seaberth (probably have to make it wider).
My likes are, looks like a good sail plan.
Lots of big ST winches
wheel house helm
cheers
