I was thinking the same thing. However, once I heard guys talk about penal recoveries (I never thought of recoveries as penal - more the lack of options which led to the harsh recovery) a light clicked to say yes, why can't bunker shots be called penal? There is really only one way out of the things if they are properly built! In any case, I wouldn't call Rye's 5th in the least penal - the 7th for sure and imo overly so. There is no good way to play the hole when 20mph downwind. All it requires is a removal of the stupid piece of wood and for aesthetics sake the stupid bush short of the green. Folks go on about a few other holes at Rye, but this is the one that annoys me the most because it has the rep for being a world class hole - yet it easily could be.
I agree with North Berwick's 1st - its a penal jobbie. It would be far better as a par 3. Tougher to get the par for sure, but if you are gonna have that sort of green site than why not use it in all its glory rather than after a rather boring lay-up?
I would call Pennard's 17th an ott penal hole.

Your selection of Calamity Corner is interesting and I would have to agree, but it is still a great hole. I spose if we chase after CC we need to look at Cruden Bay's 15th? There is a par 4 option to the hole by going right, but I am guessing it takes the same sort of carry CC requires for a layup left. Either way, CB's 15th is nowhere near the hole CC is.
I spose a few TEC holes could be called penal.
