Nothing like a straight mast.... The L2K does similar things when you put around 30 stone in it on a very windy day... goes like stink offwind though. |

lowers need to be tighter, you can see the bend in the lower mast, tip is blading reasonably well though

I would have thought that the mast is bending in that way because his weight on the wire is far more than the rig tension he's using. It's a vago, they can't use more than 15 (on a loos gauge) because the boat will bend and buckle. Lowers would indeed help but I get the feeling any additional tenion on the boat after the handful of kg he's got on the shrouds and the boat will explode. |

There is a healthy amount of forestay sag as well there.

The mystery is how he manages to find enough time away from a keyboard to fit any actual sailing in! |

With a bit of intelligent stringing, you can make a wibbly stick keep straight under monster loadings ( the mast doesn't bend much either
 ) , and the forestay is still straight.  |

came back from the yacht club and checked if any remarks had come from
the rig expert grf and it did not take long , on battens he managed to
beat himself....on a fulll battened rig batten stiffnesses depend on the loads they are subject to .so on a sitting out boat where loads are small you need soft battens otherwise no decent sail shape nor even the chance to hoist the sail...having the sail quite a fair bit of luffcurve stiff battens would make it basically impossible to hoist because you would need to bend the mast while hoisting...so the battens that we have for the d one are just the ideal stiffness.... it will though be a pleasure to see grf at queen mary coming
to check our battens .....he might have the chance to see a jolly nice boat....  , ciaooo

Well my fine fettled soft batten friend, soft they may be but they'd sure as
hell better be tapered, no way you can talk your way out of that one with an unstayed rig. In fact tapered and with vario carbon sleeved tuning rods to adjust the flow point - at that price. And whilst you're at it, if you're using those monkeys at Hyde, you'd better check you can even get the battens out, the last new sail I bought from them they'd sewn in the damn rocket tensionisers we windsurfers designed for your sorry dinghy sailing asses precisely to be able to tension and adjust battens, not as a fixed batten sewing aid.
