The Northill is probably about or almost as easily fouled as the Danforths.
With such a small fluke I think this vid performance is quite remarkable. Should hold a 25’ boat in anything but a gale. A twelve pound anchor w only a fluke as big as a 6lb anchor w a 40hp diesel running/pulling at 3000rpm. The aircraft anchor has a really big fluke compared to the cast steel original Northills due to it’s overall lightweight. I have a small steel Northill and the fluke is very small.
All anchor performance re holding should be per pound of anchor. If I had a 14lb Claw I could compare it’s performmance to my 14lb aviation steel Northill. My guess is that it should top the Claw easily. And of course w/o the Claws downsides.
