While at anchor in winds of excess of 10 knots the boat sails port to starboard. It will pull at the anchor from an angle and loosen the anchors set. In heavy winds it gets worse. I have bent a Danforth anchor which was spec. for the boat. Any solutions or reasons for this?

Chain?
Are you using a length of chain between rode and anchor? At least 10 feet, more is better. Also an anchor riding sail would help.

anchor
Good Lord, man, sounds brutal. Lay down 10' of chain and if you're in doubt of scope, let out more. What sort of bottom have we got here? Luck, Jim

Something doesn't sound right
Something is a bit strange. Bending a Danforth? Yeah, it can happen, but it is amazing that your anchor rode didn't part. What is the boat size and anchor size?

Chain
The generaly recomended amount of chain is one foot for each foot of boat lenght. Adding a kellet or sentinal (weight riding on the anchor rode) and/or a riding sail we reduce the sailing at anchor. make sure the anchor is the size recommended by the maker (bigger is better though) These are easy additons and it will make anchoring safer, more comfortable, and dependable.

Try an Anchor Riding Sail
I was out with a friend at Cuttyhunk, MA (Buzzards Bay) and his boat has the same problem. He put up a small tri-sail that he hanked onto the back stay. It had about 5 feet of line at the bottom and he raised it using the main halyard. The side facing the wind had a collapsable aluminum pole and was held forward by a line attached to his boom vang. It works like feathers on an arrow. After he raised his anchor sail, he only moved 2-3 feet to either side! Worked great. I attached a link that should give you the idea. I found it doing a search for "anchor riding sail" on the web.

No problem with H280 either
I use the Danforth that came with my H280. It has about 20ft of 3/8 chain and 120 ft of rode. I anchor all the time in 20ft of water, muddy bottom and 10-15kt wind. The boat swings left and right around the anchor, perhaps more than the larger, heavier boats, but I have had no problem with damaged anchors. The anchor did slip once, but I was in about 15kt wind plus a strong tidal current, in 20ft with sandy bottom. Even then it dragged slowly, perhaps only 20 ft or so overnight. I may need more chain and perhaps a sentinel....

Re: sailing on anchor
My 28.5 sails on the anchor back and forth as well. All that freeboard ahead of the point of lateral resistance is the cause. I use a sentinel and it doesn't really stop the sailing back and forth, but it does help keep the rode angle to a minimum. You can add all the chain you want too, but I'm sure the boat will still sail back and forth. I plan to make or buy an "anchor riding sail" as was mentioned in a previous post. I believe that's the only way to solve it.

Danforths Do Bend!
While anchored off Egmont Key, in 29kts of wind for 7 hours, I hauld up the danforth, which did not drag at all, only to find a 20 degree bend in the shaft. In this case we theorize that the flukes were embedded in limestone rock at the anchorage, and wouldn't break free until we motored over the vertical then forward and first to port, then to starbord.
