If a boat has some sort of windlass (particularly motorized), is a bow roller still necessary, or at least the retention pin? It seems counter-productive for those with windlass controls in the cockpit.
And as for windlasses, does the chain portion between the rode and anchor wrap up around it as well? Surely not. It sounds typical to have anywhere from 50 to 100' or more of chain, plus another 100 to 200' of rode. Seems like one would need a windlass with a huge drum to reel all that up.
