What's the consensus on mooring type A) mushroom anchor B) Pyramid anchor C) Poured concrete block. The bottom in mostly sandy, a little clay in spots with maybe 4" of sediment and some vegetation. This is for my 19ft Mach I Challenger MV1900CC. Boat weighs aprx 2,500lbs with full gas tank etc. The boat will stay moored from April-October in Sebago Lake (lower bay)

Properly sized any will be fine. IIRC the book Chapman's Piloting has the formulas for it.

Re: What's Everyone recommend for a mooring

Ayuh,...

I think the Trick for a Mooring block is,...

Use 2 of them....

Mine consist of a V8 engine block(Well Cleaned), with a 4' chain to an I4 engine block(Well Cleaned), with another 10' of chain,+ then the mooring line....

No matter how Hard the Tug,...
The little block might bounce slightly, if at all, but the 2ndary block will Never move.....;)

Re: What's Everyone recommend for a mooring

I would not buy one...... Cement or even better a couple of engine blocks like Bond-o uses....... I doubt you will ever retreive it so why buy it?

Re: What's Everyone recommend for a mooring

I have a mooring set up off my dock and used two 80 pound flat plates with a lug welded to the center. I then chained them together with about 5' of heavy chain and let them sink in the muck. Seems to work pretty well for my 19' boat as a convenience mooring for those times I leave it in the river overnight. I have a friend with a 36' Catalina sailboat that he moors in the ICW. He has a Dor-mor mooring anchor and that bad boy held his boat through the hurricanes of 2004, which is pretty darned impressive considering all the boats with make shift anchors which ended up on shore.

Force outboards work great are inexpensive and come in various sizes.

Re: What's Everyone recommend for a mooring

The engine block idea sounds like a cost effective method, but I'm in water that is a public water supply and I expect I'd have issues with the Utility that manages the resource using a big hunk of iron that had spent most of it's life covered in oil and grease. How would I certify that it was grease/oil free when it was tossed in the lake ? . Moving beyond the anchor type, I've done this many times in the past and mostly have done it the way my Dad taught me when I was a young boy. Remembering issues that had arisen with Dad's methods, I googled the subject and the diagram that came up involves a lot of hardware. heavy chain to sit on the bottom, lighter chain up to a large bouy, a pendant to a smalle bouy and then another pendant to hook to the eye in the bow of the boat. All of course connected by a bunch of shackles and swivels and everything galvanized. I got a one stop shopping price from Dor-Mor, maker of the pyramid anchor that was almost $2k, so I went and priced out everything listed on their bid individually from different supply houses and it still looks like over $1k plus the cost of whatever I use for the anchor. Anyway, I like what is shown on Answers.com for rigging this when I googled mooring, just wondering if anyone has a supply house they feel is the best pricewise. As always, I appreciate everyone's feedback and enjoy reading the little bits of humor added in. The G Gordon Liddy quote has long been a favorite of mine. I have stickers with that sentence on various things I own.

Re: What's Everyone recommend for a mooring

I ran across an interesting publication from INAMAR Marine Insurance regarding moorings. Two excerpts particularly caught my eye.

"The holding power of an unburied mushroom anchor is at best, twice its weight. When set, its holding power can increase to ten times its weight." (The problem identified here is a mushroom anchor, set to a certain prevailing wind direction can "spin out" of the bottom during significant wind direction shift.)

"In water, concrete loses almost one-half its weight, granite loses almost one-third; and iron loses only an eighth. This is significant. If a mooring is designed to withstand a 4,000 pound pull, one needs 8,000 lbs of concrete, 6,000 pounds of granite, or 4,500 pounds of iron. At minumum, over one ton is needed for even a small 25' yacht."

Myself, I'd love to find a couple of train car wheels and stack em on the bottom!

Ayuh,...

It appears to Me that you're Really Over-Complicating this whole thing,....

The chain is the main expense, it's only thing that can be difficult to find, scrounge, or fabricate for little or no money. The rest is just whatever you can find that fits the need.

My brother who holds a Master's License (Any Vessel, Any Waters, Any Tonnage) and sailed for 37 years after graduation from Maine Maritime Academy agrees with your asessment of the situation LOL

Re: What's Everyone recommend for a mooring

It is'nt so much the ancher as it is the line. a static line"which has no strech" will give way a lot more in sand just because it has no stretch. a stretch line cushions the pull on the ancher and will hold five times or more better.
