Same reasoning, same solution.

Not completely. I have one on my previous boat just diminish the movement but I am not sure that is detrimental to safety, I mean the movement. If you go forward and look to the chain you can see that in fact the "sailing" diminishes the pressure over the chain and therefore the pulling force on the anchor.

As far as retrieval goes I think a stainless or galvanized welded ring around the anchor rode makes for the easiest way to pull an anchor up when it will not break free. This is used on the halibut anchoring rigs that we make for fisherman. The ring can stay on the boat with the rode going through it, if large enough it can live around the anchor roller and out of the way. A light line of 1/4" size is attached to the ring. If the anchor gets stuck the ring is allowed to travel down the rode to the anchor and a pull from the opposite direction will unseat the anchor easily.

The Rocna 15 (33 lbs) is my choice for a 27' boat, currently with 80' of 5/16" g30 chain because that is what I have followed by nylon. Were I to replace the chain it would be to 1/4" G43 of 40' or 50' and nylon after that. My rig, like yours is geared for using without a windlass.

If my boat was the size of yours I would certainly have a windlass, manual or electric. I would choose a Rocna 20 (44 lbs) or a Rocna 25 (55 lbs) for a 35' boat.
When I bought the boat it came with a 25lb Delta.

That anchor was a bad joke on the bow of a 35' boat...

Agree that a riding sail doesn't eliminate 'sailing' on the hook, but it can lessen the arc, and more importantly soften the 'turnarounds'.

Our Caribbean cruising friends started using a riding sail that we gave them.. and it's still the first thing that goes up after the hook goes down. Their Bene 36.7 sailed so hard on the hook that the 'fetchup' on one end of the swing actually broke the anchor free in one instance. The boat would spring back after stretching the rode (all chain), then turn and almost sail downwind before being snatched back around.

The riding sail makes those 'fetchups' much more gentle, the bow doesn't blow as far off and they sleep better for it.
