As a returnee to sailing after a 20 year break I’m looking for some advice on the current rules for off-wind legs. To set the scene to my questions, I would make the observation that the racing context has changed in that there is now much more mixed fleet racing; and the speed range is much greater than before. This impacts one the application of the rules as convergence speeds are greater and the sailing characteristics of the boats differ. As one example, in fleets, it was less likely that you’d have an undertaking boat, but it’s very possible with RS400’s and firefly’s sailing in the same race. 1. Luffing Mast abeam has gone, but the old ‘stuff luff’ seems to have gone with it. The luff seems to have become a gentle head up rather than an aggressive defensive move; with the overtaking boat demanding ‘time’ to keep clear. Room is one thing – but is a luffed boat entitled to time? Referring to my context- giving time allows the larger 400’s to blanket my smaller firefly and just sail over me. My view is that the faster boats should not expect to walk over me, but to plan ahead and go either high or low. 2 Gaining luffing rights from leeward. The old rules limited leeward boats to not sailing above its proper course. Assuming the 400 was taking the same route of the slower boat and gained the overlap to leeward through greater speed; (ie differing ‘proper courses’ doesn’t apply) is he then entitled to luff the slower windward boat? Comment on the applications on rules in these circumstances would be appreciated - practical advice on how best to deal with these situations would be a bonus. Thanks

1. Yep, you're no longer allowed to luff so fast that contact is inevitable. But on the other hand the definition of keeping clear for the windward boat is a fair bit stricter too... There shouldn't need to be contact for windward to be disqualified or do turns, just getting so close that leeward can't luff freely should be good enough.
2. Is probably not different so much as changed circumstances. Twenty years ago most boats sailed runs at the same angle, so it would usually be obvious who was ahead when an overlap started. An asymettric boat sailing a hot angle will come up from underneath a boat square running rather than from behind so is allowed to sail its proper course, and that proper course will take a boat square running way out of its way. In the old days that would only really happen if a boat beating came up under a boat reaching, which rarely happens on Olympic style courses. |

I come to this not looking to luff for luffings sake, as no one wins, but want to be clear on how to react if I find myself in these situations. For “1”, on the odd occasion when I’ve found myself in this situation, I haven’t noticed any indication that the ‘big boats’ were minded to accept that they were limiting my right to head up – they just held on until they were over me and then sailed on. "I could have touched” is a notional argument and doesn’t get you very far.
“2” is less clear to me. Let’s scale it down and this is not now a hot-shot asymmetric, but someone just going faster on the same course. The old rules didn’t allow the undertaking boat to go higher than its proper course. Do the current rules allow for the faster boat to bear up once it’s got an overlap? Edited by Mark Antony |

the current rules do not allow a boat that established an overlap from behind to luff above it's proper course. So the answer to the question is no. |

Agree subject to proper course. Classic example is where an Asym or cat is overtaking a slower boat to leeward as that's the way the race track sets out, or perhaps the slow boat is dead running and the cats asyms are reaching down hill, even now I still get calls for "over taking boat keep clear" and "return to your proper course which is DDW". makes me laugh and cry at the same time.....
In this case, it sounds like the big boat to leeward is being an arse, BUT, I've said it beforee and I'll say it again, I would like to see the views of the ISAF/RYA where a boat to leeward has to head up because of the hole in the wind.
We've already had the discussion about proper course being "in the absence of the other boat(s)", but I do not think that when this was written the ISAF consideredn the effect of the wind blanket of the windward boat. My argument if I was leeward would be "The ind shifted and so I had to head up and sheet my kite in"; now as this was BECAUSE of the boat to windward, is the effect of the boat on thw wind a limitation on proper course or not? If the wind had simply shifted and the other boat was not there, I would have headed up and sheeted in, is the fact that the shift was caused by another boat preclude me from sailing this course.
I'd really like to take this to protest and find out.

You most certainly can luff - time does not mean half a minute, if a boat is overtaking it should be expecting a defensive manouvre and only a second or two can be required as 'time'
The time bit is to stop you doing a very sharp luff straight into the windward boat's side and causing damage, but you do not have to be so slow they are all over and past you. It can help to call 'Windward Boat keep clear' as an intention, thereby giving them 'Time'. Unfortunately faster boats do expect to walk all over a slower one - but a few days when you luff hard will make them give you more room in the future Regarding overtaking to leeward it all depends on whether they are more or less than two boats lengths to leeward when the overlap occurs. If more, then the windward boat keeps clear, if less then the leeward boat should not sail above it's proper course. BUT I can see the problem with asymmetrics and older boats in the same race - forward thinking by all boats to avoid problems usually works out fastest for ALL concerned. |

The call for time and oportunity is an interesting one, I have certainly seen in team racing the winward boat being penalised as they established a windward overlap too close to windward, so they gave themselves no oportunity to keep clear, and the umpires have used the term anticipation when explaining their decision. You may also luff as quickly as you want to, as long as the windward boat has oportunity to respond, Mr 400 will just have to luff hard and flap his kite. He will obviously try it on though with the time and oportunity thing, but if his helm is not down, he is not trying. The leeward overlap thing is another bug bear when against assymetric boats. Proper course is of course has always been in the absence of other boats, so the wind hole argument is a non starter, as they obviously took it in to account. Having been on both sides of this, I now make sure the assymetric is aware of its rights as it sails into my wind shadow, ie it has no right to make a more than a tiny adjustment if he has come from behind, if he has come from below this is a diferent situation, the strong luff which inevitably does come is a blatant foul. I think as more people have swapped in and out of assymetric boats people are becoming aware of this now. In handicap racing it is hardly ever fast to use a luff, except to deter a whole line of boats from sailing over you, so positioning is important, look for the clearest lane when you are in the smaller boat, which means looking back as well as forward, the fast boats will be looking for the quickest way past, sometimes it is best to let them have the racing line.

quite often i find in handicap racing its much faster to pass slower boats about 6or7 m to windward. that way they lose a lot of ground if they are going to luff you and so are less likely to. for me its much slower to get stuck up fighting with a gp14 than to sail an extra 5 metres in the rs300. that said, i dont normally have to pass slower boats often unless i get a bad start/ am lapping toppers/ oppies. i wouldnt say you can say an assymetrics proper course is dead downwind. common sense says that. you can still luff agressively i think. i personally regard 'time and opportunity' as me shouting 'go there and im going to head up'. if they comtinue to try and roll me then i will start to head up.......... |

Unless you're team racing or really need to keep the boat behind you, don't get into luffing matches!! If a faster boat is going to roll you, and you should really see it coming gybe or get by the lee, keep your wind clear and sail quick. I see no point in stuffing up a quicker boat they will eventually get passed you and while you fight them you are sailing slowly and giving away time to everyone else. I have explained this to a guy trying to get involved at a nats on the first run of a 4 lap race with us in 3rd and 4th......extend, extend extend. In the end I let him through and took him on the next upwind cause he was obseesed with sailing us back into the fleet! |

I might be sailing it, but it's still sh**e!

From a tactical perspective if you are going to Luff a boat overtaking you to windward the time to do it is actually before they have the overlap. If the boat is faster you may actually want to bear away once you are in their wind shadow to minimise the time in dirty air or luff behind (depends on how close the reach is). In handicap racing you are trying to minimise time going slow. If there are 1/2 a dozen fast boats all stacking up behind as you approach the ww mark come out very high. If only 1 or 2 well spaced think about going low unless that takes you into dirty wind.
