A kellet?? What a strange idea?
Why making things simple when.... You can make them complicated?? :0)
They are some confusions about « kellets » . You can use them for three main different purposes.. but unfortunately not the tree at the same time..
- 1°) To increase the holding of the anchor.. then the kellet should be as close as possible to the shank of the anchor… this is perfectly mathematically demonstrated on Alain Fraysse’s web page (http://alain.fraysse.free.fr/sail/rode/forces/forces.htm) and there is no possible discussion about this point..
- 2°) To increase the “dampening” effect.. and then the ideal position will be on the middle of the mooring rode.. but what is the interest to increase the dampening effect??
- If you have an all chain rode, you MUST use any kind of snubber.. and the dampening of the snubber should be enough..
- If you are using a mixed line with Nylon rope.. then the elasticity of the Nylon will be enough.. then forget about the kellet..
- If the surge in your anchorage start to increase and to be too big.. there is only one solution.. to leave to the open sea or to a more protected anchorage.. otherwise, sooner or latter, the DYNAMIC forces will be so big that you will either drag your anchor or break something on the deck.. kellet or not..
- The last use of a kellet will be to reduce your swinging area.. and then the kellet should be attached at a length a little bit longer than the water height..
but also then, two solutions.. If you are alone in your anchorage.. you will not care.. (and no kellet) if the anchorage is packed with other anchored boats.. you will better “swing” together with others boats (and also no kellet.:0) )
Or perhaps a solution would be to use tree kellets at the same time.. :0) :0)
I think that, if you’re thinking about using a kellet or a tandem set anchors.. it is time for you to thinks first at you anchoring gear..
