Why is the snubber hook under water? I only drop mine a few feet below the bow roller, tie it off and then release tension on the chain.
There are 3 schools of thought on bridles:
1. Short, just to unload the windlass. Your school.
2. Longer, to provide shock absorption. If anchored in shallow water and a strong wind and swell moves in, you'll be glad you have 20-30 feet of shock absorber. Otherwise, once the wind straitens the chain you have no shock absorption for wave impacts and the ride gets jerk and the forces skyrocket. Been there. One disadvantage is that the snubber may lie on the bottom in slack wind, falling off (chain hook), suffering wear or cutting. Kinda defeats the purpose of an all-chain rode.
3. Multihulls, which need long snubbers led to the bows.
There is certainly nothing wrong with school #1 if you never anchor in shallow water or in the open. But when you do, have a longer line available so that you can abandon the short snubber and connect a long one.
There is actually a 4th school, which I've been plying with. More complex, but the best of both worlds if the anchorage is shallow, the wind variable, and there is anything sharp on the bottom.
4. A long bridle anchored mid-ships or stern, then led forward to the bow. Chafe is an issue, but it allows the shock absorption of a long line without the snubber touching bottom in slack wind. It's simple to switch from #4 to #2/3 if the wind picks up.
