We already use something on the same theme and have been for almost 10 years. Buoys with a hole through the centre are available from Hippo marine and are well made if a bit expensive. Rope rather than chain is standard on our club moorings because of the wear on chain and the corrosion. The leaded polyprop rope seems to last for ever - available from big fishing fleet chandlers.

We use anchors dug into the mud because of our location. 4 anchors at the arms of an X with two ropes at each end going to one of the above buoys. the two buoys are joined below keel level with a fifth rope, so you can do figure of 8s round your 2 buoys under power without problems.

Dont think we are unique. Suspect the Kiwis are trying to sell something that already exists at least in principle if not precise detail.

Hello Kieron you poms are crazy going tyo NZ in their winter wasting your summer still I hope you enjoyed it all.
I would prefer a smaller buoy that can be lifted onto the boat deck to avoid weed slime etc on the buoy and to avoid the buoy bumping the hull. Unfortunately our local mooring authority provide the buoy much too big and we are stuck with it for the time being. Poly rope is excellent for mooring provided there is nothing for it to chafe on. I think chain on the bottom between anchors is good because it provides weight and there is not so much wear problem if it sits on the bottom and doesn't move. Ultimately you cobble together what ever is available cheaply and keep an eye on it. regards will

Notice one off the means for getting the depth of water at the mooring other than depth sounder is HARBOUR MASTER not sure he would be happy with this idea. Also bit concerned it says either measure depth at high or low water ?
Also do not like the connection to the ground weight being one end prefer it to be in the middle, to avoid the connected end lifting much like a wheel barrow is easier to lift.
One of the problems with a rope riser is it tends to get caught on the keels if the boat runs over it as the boat lifts or swings. They may have got over this problem with the weights attached to the riser.
Clearly a lot of moorings are in a bad way usually those maintained by the boat owner, when you point out a new riser or swivel would be a good idea many continue to chance the boat breaking free than spend £20, and I would guess this system is a lot more than most would contemplate paying.

Bristol Channel. Tide? Yes there is a bit.

The system works particularly well in allowing easy single handed sailing where there is a tidal flow through the moorings. We need for and aft moorings, aand this allows an approach under engine with no fear of picking up a nelson.

I agree. After being storm bound in Aberdovey a couple of weeks ago 3 days of W F7 or above; The second night being 35kts gusting to 40 kts we spent all three days building bridles, lengthening strops, taking the weight off the top chain etc to stop the buoy knocking hell out of the boat.

The worst case was the boat riding straight over the buoy and it disappearing between the hulls, every ebb! The chain was also regularly grinding up and down one of the bows before quick intervention. The problem being the 2-3 kt current working against the strong winds. At times the large floating buoy would just disappear beneath the water.

Permanent floating buoys are not IMO a good idea on exposed swinging moorings, to the point of being dangerous to the boat. Why can't they use big fender type balloons if they want this, rather than hard plastic buoys.

Ps. Aberdovey is a scary place in a Westerly severe gale at night, it certainly kept me awake /forums/images/icons/frown.gif
