Anchors in series?

yet another G+T

I am intrigued at the idea that all mobo owners seem to do sod all at anchor or whilst underway other than drink g+T! But anyway, yes, i sometimes use this anchoring method as well, although the line from rolling hitch on anchor generally has to be attached further astern to pull the boat off a "bows-to-wind" orientation. And of course, the wind might change direction quite quickly even tho the wave direction into a bay is usually more or less er into the bay - so this anchoring method is les good overnight innit - the wind direction changes and various lines started getting wrapped around things...

My main activity at anchor is to do sod all and sip G+T, but I would not dare to extrapolate this to the whole boating community.

Anyway. The system has it faults: depending on the rope type, the rolling hitch tends to slide up the rode after a few hours.

Anybody tried using a bridle? On side attached to the forward cleat, one (longer) side attached to the middle cleat. By releasing or hauling one of the lines, the angle of attack should change.

Obviously, putting a boat at right angles to the anchor increases the windage, and the load on the anchor.

The second anchor holds the first down so it bites in better.
Same principle as sliding a second down the anchor chain/rope if the first starts to lose it's grip.

On my long term study about anchors and anchoring; I did a series of tandem set anchoring.. more than 70 anchorages in the clear waters of the Med, and I did dive on nearly all.. in all types of sea grounds..

Roughly, in 62% of the anchorages, only one anchor was set, giving a false sensation of security..

Since then, I consider the "tandem set" technique as a kind of "Russian roulette" anchorage..

If you really want to use it:
- Use two similar anchors, same brand, same size.
- each anchor should be big enough to hold alone the boat
- don't attach the first anchor to the trip line hole of the second one, but instead at the extremity of the chain (attaching one anchor to the other risks to unbalance the first one)

and better than two bad anchors tandem set, /forums/images/graemlins/confused.gif use a single GOOD anchor.. /forums/images/graemlins/laugh.gif

Bridles are frequently used by multihulls to reduce the swinging around at anchor.

This technique was used frequently by wooden warships to bring guns to bear on a target when at anchor, and the use of this was particularly important for the mortar bomb vessels. To get greatest degree of sheer you need to attach a long bridleto the anchor cable which is then veered until at least one boats length clear of the vessel, you then take the other end of the bridle and attach to a cleat at the aft end of your vessel (or better still to a winch) you can either winch in the bridle, or raise/veer your anchor cable to achieve the desired angle - preferably whilst dancing a hornpipe!
