Well in a Laser 4000 I'd have to bear away more than 40 in the sort of conditions we sail in on the Medway sometimes.  But to come back to passing people to leeward.  Sadly fast asymmetrics are fast in plenty of wind but in a wind shadow they can be slower then some quite slow boats.  hence I have a guideline you might like to share.  If its windy pass to leeward, if its not windy pass to windward.  Make this decision early enough and you can get enough separation from the slow boat.  With a big asymmetric like the 4000 I have to be very wary of the smaller (none apparent wind) boats like an RS200 or Laser2000 because they can luff even in the gusts.  Similarly to pass to leeward of a boat like a Wayfarer requires quite a lot of separation since they have a wind shadow equivalent to a block of flats!

Which would hopefully solve the problem.  I get a big gust I can be bearing off 40 degrees!!!

With regard to the rules, however, I think that the key phrase is "unless she acquires right of way because of the other boats actions."

Given that you are bowling along faster than the others, you will be "rolling" the leward boats as you scoot past. That gives them right of way from "your" actions and they can luff you without warning or room. However, their timing has to be spot on. At a speed differential of 5+ kts your will only be overlapped for a couple of seconds.

I thinking in this case where I'm being over taken to leeward; Agree; IF I'M overtaking, then I'm stuffed!!  Thus my earlier statement that I'll overtake to leeward.

Agreed, I think we have done this to death now (even if we don't all agree on it). Perhaps one of the admins could move the threat to the Racing Rules section?

I'll admit to not having watched cats racing but if you were sat in front of me in a protest room trying to make that argument that you need room to bear away then I think I might stuggle to see your point of view.

15 ACQUIRING right of way

When at boat acquires right of way, she shall initially give the other boat room to keep clear, unless she acquires right of way because of the other boats actions.

To refresh ;

Room: The space a boat needs in existing conditions while manoeuvring promptly in a seamanlike way.

Remember that this is one of those few occasions in the rules where it is quite possible to penalise both L and W in the same situation - L for a rule 15 infringement and W for a rule 11 infringement, and it does happen reasonably frequently in a team race situation

I'll admit to not having watched cats racing but if you were sat in front of me in a protest room trying to make that argument that you need room to bear away then I think I might stuggle to see your point of view. 

Is there any reason why you wouldn't just blast through to leeward anyway? Certainly in the 4K when coming across Laser's etc on crossing courses or even converging course, I'd always try to go to leeward and use the extra pace to ignore the windshadow - that way you always have freedom but going above can lead to the situation you've described.

Of coure the other situation is to only do open meetings....

I sympathise with Simon too, but you've got to give yourself lots of space if you sail that sort of boat in mixed company.  I've been there in the 4000 when sailing at Bough Beech and there's been loads of kids in Toppers.

This is why I generally go below most things!!!! as I'm catching them at 10+kts!!!

I sympathise, Simon, and it's all a bit tricky when you are single handed. I am getting strangely addicted to taking the Hurricane out on my own on Thursday nights but 10kts is about my limit at the mo. But when I club race (with crew) we are often set "butterfly courses" and choosing your line through a convoy of Lasers racing across your path is a constant hassle. It's quite common for me to have to let the kite flog and dump the traveller to avoid them and I'm surpised the same isn't possible for you. Although I do appreciate that you only have two hands and the mainsheet is probably lying cleated on the tramp. While you hold onto kite sheet and tiller.

Dave

Differences are the following

1, Boat is 90kg (almost 50%) lighter than the Hurri
2, Your mainsail is only 2.5sqm bigger 15sqm vs 17.5)
3, Your Kite is only 3.5Sqm bigger (17.5 vs 21)
4, Dumping the traveller will only gain me 15-30 degrees and I'd have to lean in to get it if it has not washed out the back; Yes, usually it's all on the tramp

As I said; let the kite flog and you are usually swimming very quickly unless you BEAR OFF; the boat IS light!!!!

In order to be luffed any higher than I am already(so someone comes up from behind; I need to take the kite down or capsize on top of them.  It's not "seaman like manner" to capsize!!. 

If someone luffs I'll simply state "if you want me to avoid you in a seaman like way, I need to take the kite down.  To do that I need to bear off, come in off the wire and take it down, this will take a few seconds, I'd suggest it would be far better if you gybed away.  Do you intend to take me higher, if so, you need to bear off NOW to allow me to take the kite down, see R15"  and see what happened!!!
