I Dont think hes talking about Forefoot ,forefoot is the area at bow under water, hes talking about the shape of the top side at bow ,it usually starts mid ship and tapers down towards bow instead of level or going up which would be more correct for a offshore vessel, and i agree i never felt a bow angled down had any business on a offshore boat,if you stuffed the bow it would just amplify the situation! personally i think its just a styling thing cape horn came out with to be different!
Only positive i can think of is at low speeds it may help you see over the bow,when a boat would usually ride Bow high...
