Couple of things here. The Delta is not a claw; rather, an unhinged plow-type anchor. So, I’m not 100% clear on what type of anchor you’re referring to. However, Deltas appear to be the anchor of choice with which to equip NEW boats. Just walk a boat show dock sometime and that is what you’ll see on the new boats. They likely persist on the yachts through a few resales, etc., until arriving to a present owner who, for all anyone knows, might the first one to attempt to use it, etc. Thus discovering its “issues” and wishing replacement. One issue might even be that it’s only “just” matched to the boat; i.e., at the smallish end of the range for that boat. That would be an anchor rated for, say, a boat between 25 and 41 ft on 38-ft boat, versus a slightly larger one rated for a boat between 35 and 52 ft on a 38-ft boat. The latter would be the 35# Delta, which is the one you evidently have. So, moving on.
I’ve noticed that few sailors seem to take the trouble to fully set their anchors. The anchor rode should be veered while the boat is making some sternway or leeway to approximately 3:1 scope and then stopped off until the boat comes round head to wind, or stops making any sternway. At that point, or a few minutes after, the boat should be allowed to idle in reverse a few minutes, say two or three. After that, the boat should be powered in reverse until the anchor is clearly set (boat not making sternway), which might be immediate.
If trying to actually anchor in high wind, such as 15 kt or higher, the rode should be veered rapidly as the boat falls off to leeward. This should be done by gravity drop (not powered down by windlass). With about 3:1 scope, stop off the windlass and let the boat come up. If it doesn’t rather quickly and smartly and then hold, veer another scope amount, i.e., 4:1, and stop off. If the boat does not come up and hold after that, you may need to haul up and make a fresh attempt. However, it’s one’s option to veer to 5:1 scope. (You could also apply this to the 1st situation above,) Personally, I think it’s useful to know what is the minimum, or near minimum, scope that will set the anchor, and then work from there to get your final scope. You might still wish to test your set by powering back for a few minutes.
