Possible shroud problem??

I have a Hobie 16, and was out sailing on a pretty windy day, and before i started out the shrouds were tight and when i was done they loosened up and i am wondering if that they are starting to become weak, or should i just tighten them?

Did the jib halyard slip?

how would the jib halyard slip? what does that mean? what does it look like?
thanks

not tied properly

jib halyard keeps rig tight

a rope

The jib halyard is what is used to raise and lower the jib and ties off to the cleat on the left side of the mast after running through the block on the base of the mast . On the 16 the shrouds are tightened when you raise the jib and if the halyard slips on the cleat it would cause the shrouds to become slack since the mast would effectively be allowed to move backwards without the correct job tension. IMHO that is what will cause shrouds to be looser since the shrouds themselves are at a fixed position with no running adjustment unless someone physically undoes the clevis pin and moves them in the adjustor. Check to make sure you are cleating off the jib halyard and that the halyard line is not too thin (or thick) allowing it to slip on the cleat

Unless he has a furler system. Then rig tension is done like the 17-18-20.

How is the rig tension the same on a 16 as an 18?

Both should be rigid when sitting static on the beach. There is no specification for the tension other than that. Fyi... Lee shrouds will always go slack when under sail.

This is only true when the jib is raised, correct?

This is my question also.

Hey Matt, a simple question, but how much jib halyard tension is enough, anyway? Just enough to stiffen the shrouds? Should I really bear down on it and really tighten up the whole rig? With no hard measurement possible I'm just after the rule-o-thumb.

Thanks in advance!

He already said there's no specification for shroud tension. Pull it tight enough so the shrouds are snug (i.e. not flopping around). You want the rig tight enough that the mast doesn't bang from side to side, but not so tight that the mast won't rotate. Its a very inexact science.

On a 16 with a standard full-battened jib, you tension the whole rig by hoisting the jib. The forestay will go slack and the jib luff wire/jib halyard takes the load. Raise the jib until the shrouds are snug.

On a 16 with a furler system, the rig is tensioned in the same way that an 18 is tensioned. After the forestay is connected, one person grabs a trapeze wire and hangs their weight on it while the other person adjusts the shroud in the chainplate.

Thanks srm, that's the rule of thumb was after.
