Having had several different sailboats and two Macs we have tried Danforths and now only use the Simpson Lawrence Bruce knockoff anchors on all our boats. It's reasonably priced and so reliable.
We have 8 years of experience with this anchor in rivers, lakes, and the entire northern Gulf-the intercoastal, beaches, bays, and offshore.
They hold exceptionally well in mud, sand, rocks, and grass.
In our big sailboat-we use a 33 lb. SL Bruce -- have been the center boat in a raft up with six other sailboats-all 31'-36', approximately 72,000 pounds total, in windy conditions , with our SL Bruce and have gotten it up in the morning.
We made two complete circles, had hardly any scope maybe 4:1 scope @ 23' deep We hope to try this with some Macs sometime just to see if this will work with the smaller SL Bruce---we are just getting this boat ready to travel and bought the 16.5 pounder from Sailnet for arount $61.00 in October. It was rated for a 30 foot boat so it should perform spectacularly with our 26X. ( By the way a 33 pound Bruce is WAYYYY to big for the Mac)
We never dive our anchor and have never been let down with it's setting capabilities. Our Gulfstar's weight is 20,0000 pounds and we have held in 55 mph winds-- with no problems and can get it up the next day.
That's with swinging in complete circles with wind changes, currents, and logs! We have bow and stern anchored with a smaller 16.5 pound at the stern and the larger anchor at the bow, and weathered one very bad storm and they held perfectly.
We have spent weeks out at anchor on the SL and still haven't experienced any letdown.
A note on anchor scope: The Bruce will do with less scope than Danforth's which need a MINIMUM of 7 feet of line for every foot of depth-that mounts up there quickly if you are in deep water. They don't hold well unless you do have at least that much out. The SL Bruce can get by with as little as 2 or 3 to one in nice weather or let it out if a storm is coming your way....not necessarilly recommended by the company but works all the time in most normal conditions...
Another thing that we can't emphasize enough ,is to use a
"fish finder" and scan out the area you plan to anchor on FIRST before you drop that anchor --put it into the cleanest, levellest area you can. A fish finder will see trees, posts, boulders, etc. and describe the bottom composition so that you can set that anchor properly and also get it up in the morning...It's the cheapest anchor helping device yet!
The next best thing to do is to really learn how to set down an anchor and
chain and do it right. Practice Practice Practice.
The SL Bruce usually comes right up but in the event that it's really stuck in the bottom do the following:
In the morning while everyone in the anchorage is wrestling with their ground tackle-trying to untwist Bahamian style (2) anchors and pulling up stuff, like trees and tires or tons of mud---all you have to do is go forward, pull up the rode until it's straight, go back to the cockpit for aother cup of coffee and let the boat bounce around ---when you are finished with the last cup---go back and finish pulling up your anchorline and anchor and Viola! It works almost all of the time. It works especially well if you scanned your bottom with that fish finder! ( and haven't hooked a tree!)
Our best friend has a Bulwagga and swears by it---it is ugly [/img]
ANCHOR SWING....well it is just the way it is with all ultralights with high freeboard like the Mac---rocker stoppers help but we use the anchor sail that we purchased from Sailrite years and years ago...we have used it on all our boats with sucess. It does not stop the swinging---we doubt that anything will stop that swinging (except bow and stern anchoring which is not always possible) but the anchor sail certainly helps.
We suggest that in very stormy conditions to take it off-go below and keep you mind off the swinging

Soo if you want to limit your swing to 10 degrees instead of 40 degrees then go for it. Buy that anchor sail or if you sew make one out of canvass for a trial run....Keep your rudders up and the centerboard too, it keeps the boat up on the anchor instead of tugging at it-why, you can even grab the anchorline with your hand and feel slack on it in windy conditions . It will de-stress the load on your anchor.
Go ahead and argue with us----we have been there time after time, anchorage after anchorage watching people anchor only to drag around later--we don't.
As for Practical Sailor-well, it's nice reading but not always right. IMO.
