I have a nice-looking ss bow roller installed by the factory. Fact is, I don't anchor much, but when I have I have found the roller rig a disappointment.
Even if you install a custom bow roller over your lip, it will likely not be strong enough for hard winching on a stuck anchor. Mine has hairline gelcoat cracks despite being through-bolted securely. The lever arm, even though quite short, strains the connection to the deck.
I have found that dealing with a 35-pound anchor "out there" on the 4-inch roller is very awkward, simply because--as your photo shows--there is no spare room in that pointy zone of pulpit, forestay, and roller drum. If the rode/chain hangs up or gets off the roller, it's difficult to deal with--even in a flat calm. I only have 35 feet of chain, but that's heavy and if the anchor is stuck it doesn't stretch, and the buoyancy force of even small waves on the roller is large.
The answer is a robust roller with a windlass and chain locker. Not a common solution on our smaller Ericsons.
So, the easiest way for me to deal with anchoring is to lower and retrieve the anchor over the starboard bow. My aluminum rubrail there is scarred from pulling chain over it. In a seaway, there is simply no way to daintily stand and retrieve the chain hand over hand like it was a pearl necklace. There's no available winch without rigging snatch blocks. You sometimes need to rest the chain against the rub rail. I plan someday to install a piece of oak to protect the rubrail from the chain.
Anyway, I find it all awkward and the bow roller not much of a solution. Furthermore, unless you rig a bridle, the boat is attached to only one cleat, which is sure not the equivalent of a sampson post.
I hope someone has a better way of anchoring our pointy boats.
