Great work by Peter Kraszewski (PRO) getting the races of quickly in changing winds. Thanks to all the scorers too for the hard work in the cold and wind.

And thanks to Peter Van Rossem for putting the whole thing together!

I can tell you that this has been tried, although not recently to the best of my knowledge. I have seen older plate runners that were ground asymmetrically.  I have no idea whether or not they worked or were fast, etc. etc.  Perhaps somebody with more experience would know more about what happened.

There seem to be a number of considerations worth looking into.  What sail are you using?  How old is it?  How much do you weigh?  How are you steering when the boat starts to hike?  It's possible that the mast is too stiff even if it does appear to be bending, or maybe your plank is too stiff.

If you are using a rather full sail, or an old one that is blown out, that may cause your hiking problems.  You may need a flatter sail if you are not very heavy ie.<140lbs.  You might also want to lower the sail, depending on where it is now.

Steer up into the wind slightly as the boat starts to hike.  Since you are suggesting that the runner lifts gently, I would guess that steering up a little will solve the problem.  Raking the mast back will probably give you more mast bend, but you will also lose some pointing ability and perhaps some speed.  There limits to the amount of bend a mast will tolerate before unintended catastrophic events occur.  Experiment a bit until you figure out what works.

As a 220lb+ sailor it seems to me there are several considerations here.  I think Eric is correct on the plank stiffness, but what about runner profile and sharpness?  If these guys are sailing around on really flat runners that aren't very sharp, they are likely to get into trouble. This is especially true on some of the rock hard ice I sail on in Wisconsin, but I'm not sure how relevant that is in NS.  In my own case I tend not to sail around on really sharp runners.  They are not flat and have about about 20 inches of .008 crown, if not more.  I also don't sail on 90 degree runners all that much, as 95 or 100 degrees seems to be adequate until it is really blowing.  I try not to make sudden sharp maneuvers, but outside of those situations, spinning out is not something I worry much about.  I'm not real fast, so some other opinions might be worthwhile.

I use a fiberglass mast and it bends well, as i can tell. Going upwind, as i sheet in, mast starts to bend, and at some point windward runner lifts off gently. If I pull the mainsheet harder the mast will bend more and boat hikes more. Maybe i should tilt my mast farther back to make it flex earlier for given conditions?

Hiking is often caused by type of mast. What mast are you using?
My first year of Iceboating I had an aluminum mast. Every puff, I hiked. I then tried a wood mast. Not as bad. Once I sailed a glass-carbon mast I rarely hike.

Hello guys. Quick newb question here.
If hiking occurs, does it mean you get the most power out of your rig possible and so you go as fast as you can at given point of sail with given settings (aside from mainsheet trim)?
Or could it be that current sail trim just develops a lot of heeling moment for no good?

Hello everyone.
Through my entire first DN racing season I was suffering with poor side runners grip.
Major cause of it is mediocre edge maintaining. I have a lot to learn in this department.
However, aside from that, I am long curious of why exactly asymmetric grind profiles (chisel profile in extreme) do not work (or everyone would probably use em).

My possible pros and cons suggestions are as follows:
+ we want side runners to hold in one direction each so why use symmetric profile on side runners at all?
+ chisel grind seems to be waaaay easier to execute and maintain
+ asymmetric grind could probably have broader angle than symmetrical without compromising grip and thus have less friction

- this is unconventional and scary and everyone is fine with symmetrical so just go practice sharpening))
- chisel runners could simply go apart from each other due to unbalanced ice pressure (my major concern)
- chisel shape could behave poorly as (if) negative camber develops with plank bend under load. probably not so much of a problem with less radical asymmetric shapes

Any thoughts are appreciated.

BARE dive suit-  great for wearing while racing a DN-  warm, windproof, flexible, streamlined, not bulky so offers room to move around in cockpit.

Also good for warm water diving on it's own or to be worn under a dry suit or wet suit in cold weather.  Good for diving, snorkeling, surfing, windsurfing, kayaking, anything water-related.

Size XL

Lycra outer layer, fleece inner layer.  Front zipper.  Warm and flexible. 

A few battle scars but overall in good shape!
