pushing the rudder away from you to point up when the boat is heeled to windward is very unnatural, it feels awful, as the boat is trying to bear away and you are trying to stop it, its very slow!
pulling the rudder towards you is the correct way to do it, no if's or buts. you dont have to bear away too much, a sharp stab is usually enough to bring it flat again, if you dont want to bear off on a long arc. |

I always thought the bearing away thing is for when you are sailing by the lee, as effectively the sail is reversed. When on a run but not by the lee, luffing up will be the way to save yourself. I think I'd like some warmer water to fall into than we currently have to figure out which one works better when!

My understanding is that it has very little to do with the sail, and it's all about using the lift from the rudder to get the boat level. If you push the tiller the lift acts in the opposite way and pulls the boat over on top of you. |

you are correct GarethT, it is all to do with the lift of the rudder rather than anything to do with the sails or your angle to the wind.
to test this without gettig wet, just find a boat with a cradle trolley, like an RS4/200, put it on the trolley as if its heeled, put the rudder on and then grab hold of the rudder blade and physically pull towards whatever gunwhale is higher, you will see the boat tries to heel even more. this demonstrates pushing the tiller away when the boat is heeled to windward, or pulling the tiller towards you when heeled to leeward. http://www.roostersailing.com/merchant2/merchant.mvc?Screen= hints&Store_Code=1 then click on the 4th dimension link. this explains the theory quite well with some videos |

I always thought that death roll was caused by wind spilling from the top of the sail pushing the mast sideways to windward, when it goes too far the righting moment forces shove the boat back and the rock and roll starts. Am I wrong then?

Im so gald I was right to question the Byte class video guite
I did think that heading up would make the death part come faster. |

Now now you naughty boys and girls you are not allowed to call it a death roll, it scares beginners. Sailing schools call it a SPEED WOBBLE. After hearing this from an instructor sailing in the FD fleet we decided to call it a PINK FLUFFY KITTEN. You could never get scared of that could you! Ha! Edited by Strangler |

I call it an 'oh b******s', normally about 0.2s before I hit the water |

It's called "Death Roll" because the outcome is inevitable like death, not because it will cause death. No problem for the "undead" then, (GRF) ?
