Below is an email from my friend Mathew, not only does he own the most beautiful boat ever designed, a Lyle Hess 26; he is also the most enthusiastic sailor I have ever met. Last time I he was in town he tried to get me to kedge the boat out of the slip with 20 knots on the stern.
I don’t think my little “experiment” was really accurate enough to say that the CQR is better than the delta, but I can tell you my bruce is for sale now. Here’s what the experiment looked like:
All anchors laid out on their sides.
I pulled all the anchors by hand with as much traction as I could get in the sand. The bruce was the hardest to pull initially, but as you can see, it didn’t set properly. The CQR was the first to dig in.
When I pulled with the car, the delta sure moved a lot of sand. It made the tires skid after 14 feet.
The CQR dug down a littler quicker. It made the tires skid after 10 feet.
The bruce was dragged across the entire beach without it setting properly. After physically forcing the point down into the sand, I still dragged it across the entire beach without perceptible resistance.
All anchors were 33 – 35 # and the true versions of their respective designs.
There was no way of assessing the actual tension using the car.
All anchors were pulled with the line parallel to the sand.
I was only able to get one trial in before the port official came to hassle me.
I pulled the bruce with and without the 9/16″ chain. No noticeable difference.
A better method would use a fixed point against which a block and tackle are set with a scale. The block and tackle could supply a steady pull while the scale measures the maximum pull the anchor is able to hold. The use of a car is not appropriate for true comparison. Next time, eh?
