rib mooring

a stupid question no doubt but as a hard boat owner maybe you guys could explain the prefered method to tying your ribs up at the bow. Do you all use the eye on the bow, or the plastic guides on the tubes or even a proper cleat on the boat deck... if so doesnt it chaff and ruin your tubes? It seems to me like the front warp on a rib is undercatered for!

David Manning wrote a whole article on how best to do this in Rib Int.
Excellent article it was too.

that mag. DM would there be any chance of getting a draft on the forum ?

I stupidly used the cleat on the bow & over nigh it rubbed through the first layer of the tube!
I now always use the eye on the bow (I have not fallen in yet!)

When was this?

My solicitors have been briefed to address this heinous accusation. I would never allow my literary talents to be used in down market magazines which can't be bought over the counter.

I think that Brian has been at the gin again and has got me mixed up with Dave Mallett who is much older and uglier than me.

Fortunately for the owners of positively dangerous 'med style' ribs, we don't have to worry about warp chafe.

although im not a real avon rib fan, do you think they have the right idea with the raised platform with fitted cleates etc similar to

could this be strong enough? otherwise it all seems a bit of a comprimise and im affraid to say it but i think us hard boaters have got it good here!

Well I did not know that the Osprey Viper is a med rib! Is this why the sun always shines when I’m out?

I agree, Dave Mallet's article had some good ideas.

I anchor my rib for 4-5 weeks most summers. Originally, I used rope shackled to chain but the rope quickly wore through because the shackles formed a pivot and the rope section dragged from side to side. Following that I spliced the rope to the chain but, over time, it began to show chafing and I never really trusted it. The chain section tended to lie on the seabed and, as the boat swung about, the chain/warp rolled. The splice is always a bit larger than the chain so it was the point of wear. Also, if the weather is bad, there can be a surprising amount of wear and breakage of the rope fibres at the water surface where the buoy is attached.

For the last few years I've used chain throughout. It is brought over the bow and attached to a U-bolt inside the boat. The tube has a bit of rubber strake down the inside of the bow for protection but it is hardly required because the chain is always in tension and this limits the rubbing to virtually zero. From the top of the bow, outwards, there is the usual D rubbing strake with a slot cut along it.

I've had a couple of lucky escapes when using the caribiner style clip and I now don't use them at all. The type which are oval and have a nut which runs down to complete the link are excellent.

I hope this is of some use to you.

Jeff
From a roped access point of view they would be called a Mallion Rapide.

As my boat is going to be on trot moorings in a tidal area.
I was going to put a nylon bridle on the stern chain mooring buoy and a main nylon line to the buoy from the bow eye and back up line.
I was also going to put a security chain from the buoy to a 'U' bolt in the deck.
As this is just going to an unconnected 'u' bolt will it lead electrolisys?

I attach the rope to the bow eye so any tension is pulling against that, the free end of the rope is then looped loosely up over the tubes into the boat and secured to a samson post.

Thus in the event the rope should come free from the bow eye, (or some snivelling rug rat should find it funny to release it from the bow eye) the boat can't float off.

If I need to leave the rib anchored in the sea overnight I deploy two anchors both attached in simalr fashion to the bow eye and loose end of rope to the samson post.

I have seen some ribs that have a fairlead guard / rubbing strake guide fitted to the bow so the rope rubs this instead of the tube.

Well its my apologies to both Dave Manning and Dave Mallett then (not quite sure who gets the lion's share of the apology though).
Lets just say it was DM then?

The method he described was as detailed by Martin Stacey. The towing eye's rope is attched to the anchor line, taking the strain and the balance of the anchor line is brought inboard and fastened separately. Thus the towing eye takes the strain, the remaining length of the anchor line acts as both safety, and as an aid to hauling in the anchor.
