Same idea, more common - manhole covers. Available from a street near

RE. getting the train wheels "out there" .
When we set up my dad's mooring, (4 trainwheels) we simply sued the anchor roller on his Bayfield 23 with a 2 part prushase led to a winch. We'd pick up the wheels 1 by one, take them out tot he mooring aite and lower them to the bottom.. Matt Sal's Dad wrote: Same idea, more common - manhole covers. Available from a street near you...

a fifteen foot tall statue of elvis, especially if it had his guitar
sticking out on both sides. on a serious note, i thought that most moorings were poured concrete, poured right on the spot using whatever kind of form you can make/find. concrete cures just fine under water once it's been poured, and i'm sure concrete is easier to deal than a fifteen foot tall statue of elvis.

Atlantic salt water, in a fairly well protected cove, with 6' tides, in about 10-15' of water, virtually no traffic and a spit serving as immediate breakwater. Alternative suggestions to a mushroom would be appreciated. Courtney |

Courtney My understanding is that concrete loses a lot of it's 'weight' in water, whereas steel/iron do not and given the recent hurricane rash I'd prefer all I can reasonably get. Plus I'm not in an area catering to such services as installing moorings, for example. Gratefully, Courtney |

Gratefully, Courtney correct on the "losing it's weight" in water ... sal****er is 64 lbs per cu ft (displaces 64 lbs per cu ft) per my pocket ref on material weights (any typos are mine) cast iron 450 lb/cu ft portland cement 100 lb/cu ft mortar cement 135 lb/cu ft gravel concrete 150 lb/cu ft limestone w/Portland concrete 148 lb/cu ft marble 160 lb/cu ft so, water will displace 64 lbs of an item, so cast iron has a bottom weight in salt water of 386 lbs per cu/ft the different cement mixes are 36 to 86 lbs per cu ft when in the water I've seen both cement and marble slab moorings in this area ... in blocks (not formed to dig) and while they tend to sink in over time depending on bottom composition. I've also seen them move to shore during a storm. I personally wouldn't use a block without adding a mushroom to the works ... the block would prevent the mushroom from lifting, the mushroom would keep the block from moving. note: I am not a ground tackle expert ... I have used the weight formulas to determine lift bag requirements or drums to perform uw lifts and recovery. - Ed -- refillable drysuit talc bag $10.95 ppd http://www.underwaterusa.com |

Plus I'm not in an area catering to such services as installing moorings, for example. Steel has a higher density than concrete so it takes more concrete to make a proper mooring. That said, concrete mooring blocks are quite common and relatively cheap. You only need about 6 cubic feet to make a 2,000 lb block which is plenty of weight even allowing for the lower density. Any concrete plant or competent "do it yourselfer" could make one for you at low cost. Some concrete plants make them up out of their excess production and may have a few laying around. Typically a loop of 3/4 inch chain or wire rope is cast into the block as an anchor point. Unless you own a floating work barge with hoist, you will need professional assistance to transport the block and plant it. |
