You are going to love this. Friday special courtesy of Yachting World
Scratching my head thinking this one through and wondering who came up with this rig. Seems to have a stay at the top of the mast and huge flexibility at the mid point. Generates significant depowering as seem to be sheeted in when reaching. Would love to have a go........ Discuss http://www.youtube.com/watch?v=cRSw73AC4gk |

It does look crazy, but they've been going damn fast for many years, so must be doing something right.

Not sure about the mast bend but surely they are sheeted in as they are sailing on a fairly extreme apparant wind?

I love that they go so fast they don't sheet out even a little bit when bearing away, and I agree that I don't understand how the mast works, but it must be fast!
As for having a go - maybe... looks like it would hurt when it went wrong! |

Its a fairly "conventional" over rotating semi wing mast except that normally we wet water sailors put diamonds on to control the low down bend. A Tasar mast ith the diamonds disconnected would bend in a similar way until it went bang.
The extreme mast bend gives excellent control of the leech and twist without huge amounts of kicker. Hard to explain why in a para, but trust me, it does. Thoe hounds are somewhere like 2/3 or 3/4 the way up. Because ice boats are so very fast they generate unbelievable (to us) amounts of apparent wind which is why they are sheeted in so hard all the time. Needless to say they never run square, always gybe downwind. From what I can make out to go upwind you just point the boat at the right angle and wait for it to slow down enough for the sail to set! I'd love a go, I think... |

Having competed in 2 european championships in these boats I can tell you that they are effing quick! The kids race in optimist rigged ones which do 50 knots. Back in those days we had custom designed flat and heavier sails. The Polish, estonian, swedish sailors just used their old practice sails mostly. Suppose that was fair, they had time on the ice, we had nice sails....
The reason the DN masts bend like that is that they are now all Glass fibre. The alloy ones don't do this and are far too twitchy to be fast these days. You are running huge sheet loads, probably twice that of a wet boat. Have a go, if you want to know how i can see if i can get hold of the Swedish Ice sailing lot for you, they have a trailer full of boats that you can use, i think for free. That's how it used to be anyway!

You wouldn't want to be run over by one of those doing 60kts though!

They do look quick.. I wonder what would happen if you sailed them properly, standing up canting a free sail rig to weather, either way I'd love a go, have tried the ones with wheels on they can be a blast as well doesn't the Farr 37 guy do it, Jack Sparrow?

Yep, iGRF I do. But I have never ice yachted.
This weekend is one of Brean Landyacht Clubs Regatta's as part of the British Championships. So go and have a look. Mini yachts, Standart's, Class 5, Class 3 will be racing. The apparent wind generated is amazing. Once you have momentum you are sheeted in to the centreline both up and downwind.
