chain rode

[vizwhiz]

The snubber has the anti-shock qualities, but so does a length of nylon rode. I'm having trouble understanding how it helps keep the chain on the bottom.

Russ, I don't think the rubber snubber is intended to keep the chain on the bottom, just provide...snubbing...so the shock of being blown from slack rode to tight rode is taken up. That could be due to waves, wind, etc.
#1 and #2 are both intended to help keep the anchor in place on the bottom by keeping the angle of pull against the anchor lower, and secondarily to provide snubbing by creating slack in the line and giving added weight that the line has to pick up when tensioning.
In reality, longer scope makes the angle shorter also, which should improve anchor grip. However, if you don't have space for long scope, for example, one of the first two should improve the anchor grip.

No Doubt Gentlemen, not every solution will work for every scenario..Do what you find works for you.. On Lake Michigan its pretty much 30=90 feet of depth within eyesight of shore..In Port Charlotte Harbor and the surrounding area's I never anchored in over 10 feet ..
30 feet of 5/16's chain is not all that heavy to pull up.. To carry it in a bag is.... another issue..

I like picture #2, and that is what I do when needed. You do not always need a sentenal but you have it when you do. I generally anchor in areas that have tide activity. That means that you and all the others swing in a circle as the tide changes and goes in and out. If you use a stern anchor or some means that keeps you from swinging, that will mess up the patern for the other boats.. Someone might bump into you, The more wind the more chain or the more need of a sentenal. I do not know how a mushroom anchor down on the anchor or anchor chain will affect the resetting of the anchor when it tries to turn 180 deg and reset. On the stern to keep you from swinging is not good in tide areas.

Chuck,
You missed the point, I only used a plastic covered dingy anchor as a cheap way of adding weight to Chain. You can add any type of weight to the chain rode.
You also can use a seperate line attach to it.
It's just more simple to attach it directly to the chain.
In tidal areas it makes no diffrence but doing a 180 degree set it will help reset a anchor much faster.
Basically what you are doing is reducing the scope with deep sag to allow deeper digin of the anchor and less shock of the line to prevent anchor from dragging.
Next time you are out and you have a poor anchor ground or deep water or wind/waves are strong...try it. Cost about $20 for the mushroom and $5 for the attachment.
Sleep tight with no Woories.
A Bahimian Moor is with anchor set at Bow and a stearn anchor set with both rodes at the Bow. This keeps the boat in same position regardless of swing and reverse tidal conditions and is required in very close moorings, One also needs to ck other boats anchor patterns.
The Mushroom almost does the same thing with a bit more swing room as you use a shorter scope and don't have to worry about rodes twisting around each swing of the tide.
There is always someone that thinks a 15 to one scope is better and takes up a 500 ft diamiter swing room...Anchor someplace else.

Thanks for the info.

Over the 6 years we have had trust me and the many many anchorages in totally different situations it has taught me to be flexible when thinking of anchoring each night or even lunch stops, from narrow tidal rivers more resembling creeks in width but 9m deep and 8m tides with no way to escape, to open lakes with minimal wind, the most important lesson especially for mac owners is that no one anchorage is the same and no rule except basics apply, couple all the differences with the macs ability to dance in the oddest ways you need to soak up every available bit of info to test and store it.
Our very first anchorage on an open lake using a Danforth on the edge of a hidden old riverbed found ourselves tangled in some willow trees at 2am, probably have dragged 8-10 times since but never had any damage due the admirals light sleeping usually but it's been an amazing learning curve with a lot of hard and fast rules being disproved except in particular situations, even when tired the anchorage job cannot be treated lightly or as just a standard procedure without taking into account local conditions especially when they can change without much notice if you are not a local.
We anchored in a river up along the Cape York Coastline the river (Smitbyrne?) was fairly wide (about 90m) and I had put out anchors on each side of the bow allowing for the expected tide change (5m) on a good holding sandy bottom but good scope to allow for changing depth and wind and enough clearance even at low tide to miss either bank or low water areas.
We woke up at 4am with a roaring wind and the boat spinning almost in circles I managed to get up the bow and use the anchor ropes to pull us off dangerous areas and then after a hectic 1/2 hour found the wind just dropped and the black as ink sky's disappeared, after resetting anchors tried to get back to sleep, the next morning and following mornings half an hour later each day the same thing happened but I was far better prepared.
When we got back to the Norman River by this time the phenomenon occurred in daylight and it truly is a phenomenon peculiar to that part of the world called the Morning glory and it truly is glorious to see, provided you are not underneath the bloody thing and not expecting it, might be ok for hang gliders in daylight though.

Got stuck in the King River off the Cambridge Gulf in the Kimberlies with 8m tides and we kept going up looking for more fish and a bettor anchorage, well we found plenty of fish but not the anchorage when dark and the sandflies arrived so had to make do with what we had on dropping tide, found a hole of 7- 9m that ran for about 60m but could see rocky bottom on sounder.
Dropped one anchor in middle of river which was max 20m wide and secured stern with lines to trees on either side bank, about 1am? when we were in less than 1m of water on rocky bottom with ropes having been let out to allow for a dropping tide we were confronted with a stern tide and loosening ropes and rocks and trees on either sides but the stream by now was no more than 10m wide fortunately all lines held and had a mate on board not the admiral.
