Yeah, but what ever we'll at least be able to get it wet. I'll look out for the coral. I was also looking at the anchorage right on the other side of the island which has sufficient depth. BTW, any fishing around Great Sale?

I have not seen any fishing around there. It looks pretty barren. If the wind is out of the West the other side could be used. However, the prevailing winds in that area are easterlies.

How much of failing in the grass is relative to size and weight? I can understand that as anchor size gets smaller it might be tougher to penetrate the bottom, but does that change with bigger anchors of the same type? Can't imagine a 2,000 pound anchor or most any style will have a problem cutting through the weeds.

I have a 30KG (67 pound) Bruce (real one, not a copy), and am wondering what to expect when I finally find some grass. So far it's been great; digs in first time every time; has never slipped; stays put when the wind changes 180 degrees; doesn't seem to mind the 60 degree swings my boat constantly does at anchor. What should I expect from it in grassy bottom?

"The answer to that would be whatever anchor was in stock."
Don, That's exactly what I would have said If I had thought of it.
In fact I try to stock the types of anchors that people ask for in my area.
Currently that's Delta, Danforth style in steel and aluminum, and the Lewmar Bruce knock off.

I'm trying to decide on which roll bar anchor to stock.
I'll be interested in Oliver's report.

Often discussed is the ability for bigger anchors of ALL types to work better because their sheer size and weight overcomes things like thin bottom types (grass, mussels, reasonable thickness oyster beds, hard but thin layers).

My 33 pound Bruce on my sportfish never had an issue with setting...never did test it in extreme conditions but held fine in varied bottoms in 35 gusting higher tropical storm winds but nicely protected anchorages. I would thing greatly oversized Bruces are a great anchor...just as good as their newgen little brothers but only when over 50 pounds to overcome some of their shortfalls and way oversized for their poor holding power reputation (for their sze).

Ask a man about his car and odds are he'll tell you it's great. Ask him about it after he's sold it and you might get a different story.

Sarca user here.
I`m thinking, thread title could have been "Rocna out to Grass" (like retiring an old racehorse).

How true! One never hears "my neighbor on the float has an XXX and it's really great".

We all seem to have a little self centered problem. Kind of a "Why don't you just get smart and use what I use and in time you'll come around and think what I think". This is obviously true as a lot of us rave about how wonderful our stuff and ideas are and seem to find it puzzling why others don't jump up and agree.

A lot of it stems from the fact that we have experience only w our stuff. I thought my 18lb anchor did a super job of holding us firm in a 50 knot gale but a Rocna may have done as well or perhaps another kind of anchor. One guy thinks a 34' boat is just too small and another thinks 34' is really big.

On the positive side it's great that so many of us love our boats so much. Makes it much easier to pay the money and do all the work required.

And of course loving ourselves is good for self esteem.

my Mason supreme had difficulty settings in grassy bottoms. admittedly at 45 pounds it was too small for my boat.my new mantus at a 105 pounds is way over size and sets the first time. I do sleep better on the hook now

Rocna's are great

Over the past six months and about 1500 miles we have used our new 88lb Rocna alot and have been very happy with its performance in a variety of bottoms and weather situations.

We certainly sleep well although we always use our Anchor Watch program

Motion,
I suspect the size of an anchor has little to do w it's ability to set properly. Small boats and small anchors don't seem to have a problem. I really think the design has almost everything to do w setting. And setting wise I'm betting your Mantus is a very good choice.

Holding is another matter dependent on a different agenda. Mostly the size of the fluke/s and it's angle in the bottom. The shape of the fluke too but to a lesser degree. Concave is best but convex works well too and has it's own benefits. Weight is a factor also but not as primary as the above.

But all things considered your 105lb Mantus should keep you in place.

Oliver, if you see a big sportfish with a very tall tower named Tumbleweed, say hello to my friend John. He hangs out in that area. Usually at Grand Cay, but he gets around.

Oliver, I should mention that John owns his own backhoe. You and your Dad can talk hole digging with him.
