Its for sale in Airlie. Still has runners as far as im aware


Yeah, almost correct, It was sailed here by a Pom, and was in pretty bad shape, nothing major, buts lots of niggly minor maintenance issues, deck gear, halyards etc. It was re-rigged before leaving UK with new stick and rod rigging. Shame they didn't sweep it back at that point.

Very poor job done by slipway in Sydney on the antifoul after purchase before delivery to QLD, (wondered why they dropped in before I got there to inspect) but at least this forced by hand and made me sand blast back to glass in February. Ran out of time so needs to come out again to refair from Sail Drive aft, hopefully before ABRW this year.

I have replaced the runners and checks, repainted cabin top and decks

There is a lot of disinformation on this page, like the death role photo alegedly in 15knots. We hold Masthead bags down hill in 25+ knots, and the boat handles the gusts with ease. Admittedly, this is one with the Modified keel, and this makes it fantastic up hill. Pay the price for the extra weight downhill. We still don't have a regatta set of sails, and have only had the budget to add Club level main and no.1.5 genoa.

Not sure what is expected of an IMS designed semi displacement hull, but at Hamilton Island Race Week last year, we beat the Stomp 38 around the track a few times and it has an IRC rating over 1.2, and you can buy one for over $250k.

Next stage is to look at the IRC Optimization with non overlappers, with a view to sweeping back the rig.

The cost regarding the Chain Plate comment is incorrect, the bulkheads are in place and ready to recieve the chain plates, the mast needs to be restepped 200mm back behind forward bulkhed and chain plates placed in same position as Sydney 38. Structural worl estinates are in range of $2500 - $3000, plus cost of rigging ($10K ish). Indications are that the integrity of the stick is fine for masthead backstay loads in swept back config. If anyone has firm info to contrary please speak up.

IRC Rating is about 1.16ish with overlappers, and as low as 1.145 with non overlappers and frac kites, so the Farr 40 comment is way off, with most Farr 40's in the 1.18 range as far as I can see.

Anyway, that is my update on a 12 year old boat that was part of the winning dutch team in the 1999 Admirals Cup.


Interesting post.

Is Tezza still about anyone?

Does he still own his sydney40?

Seems we are going through many similar alterations.

I took a lok at the change of rig and decided that without paying for a carbon mast it probably wasn't worth the expense just for a tin mast.

What rig did this one have on it? Did it get converted to swept?

1 in chile (victoria from sydney?)
1 in france,
1 in Uk (mine)
2 in SE asia (windsikher + ex babe)

By lots who do you mean?

Windsikher, Ex Babe who else?

Windsikher appears to be the best run boat out of all the sydney40's at present.

Ha ha! Only one SYD40...by "lot" he means:

Ker40
GTS43
King40
Swan42
GP42
Archie40
Mills40
Elan420
J130
SYD40

See the IRC1 fleet here. And watch the results here as they unfold in late May to see how the SYD40 does against a bunch of IRC-optimized 40-ers.

Great to See Dynamite Racing in IRC 1 - IIRC was Bruce Farr's first ever Two Tonner. Loved that boat as a kid - was pure porn at the time, basically a scaled up Farr 1104 hull form.

What boat is EFG Bank Mandrake? Is that a MAT 12 or some other Mills design?

Mandrake is a Mills40 (not a Mills designed King40 or a Mat12).

She is approx 400kgs lighter than the King40 and has a wider aft section for better reaching performance...but she gives the King40 a bit of time on corrected.

Here's Mark Mills' design link.

Hello everybody!
When you say: "Russia" maybe you mean the Ukraine. Because my friend just bought Sydney 40 (Hull No 4008) in Holland this April and I helped him to bring it from Slovenia to Odessa, Ukraine. Before Holland this boat was located in Scotland. Who knows its history? It might be interesting for us. As well we need advices concerning the tuning og Sydney 40. Thank you in advance.

That's the one.
I was told it was Russia.

What are new owners plans?

I'm going through a few alterations myself including a new keel. So if he is looking at making changes I'm sure I can help.

I thought I saw the old Sydney 40 "Bull" back on the market in SoCal. (Newport or Long Beach?) That what you're looking at? I thought this boat sold about 2-3 years ago, so you might look around SoCal for race results. Not familiar in that dept myself.

Reputation for quality construction.


Didn't 'Bull' have a suit of CubenFibre sails?

Congrats on the purchase.

Looks like there are going to be a few Sydney 40's active again around the world.

Let me know if you need any help with ideas etc. I've gone through a load of different ideas with Andrew Dovell already.

For interest, I've attached my targets with the new keel.

These are different to any other sydney40 as the keel is a max RM IRC keel done this year. It's about 5seconds per mile faster uphill than the original ballast configuration and a second or two faster than the config on boats like tuf-lufs old ride (his keel I believe was an IRC take on the two piece iron/lead job but with a new bottom section torpedo bulb). Or so the VPP study says. Who knows what the reality will be. Downhill the weight saving still makes her quicker but the big difference is not until about 20knots TWS, when it is again 5s per mile faster.

But anyway, it should still give you some idea of where you should be.

Enjoy.

Looks fast upwind on those numbers. Know what the predicted IRC rating is?

Yeah those numbers make her look pretty nice upwind. If of course they end up being true.

We reckon we are going to come in under ex-Babe and under High Anxiety - so about 1.154

We are also looking at sail plan changes.

I'm done with exploring the rig changes for now and have refurbed / replaced the existing rig and rigging and kept it as standard. I think its a good setup as long as I can get the tuning right.

Nice - congrats! It's a very rewarding IRC yacht if you tickle it right.

As you've noticed, there's heaps of info in here and there is more on other threads...if you have the patience to search (do it!!).

I raced my SYD40 like an angry IRC mofo for over two years in SE Asia. Love talking about it...just ask.

P.S. - the Singapore SYD40's rating just dropped a shit-load for a change in IRC mood from 2011 to 2012...make sure you get the same in Oz! I'm still wincing as my Mills/King40 went up during the same re-rating. Bah!!

RANSA will be her club. In summer i intend to do Wednesdays with the Edwards and
the evening twighlight with CYCA. Fridays RANSA twighlight.

During winter. Haven't decided but Sat RANSA or Sun CYCA.

I will get a few seasons under my belt before considering alterations for IRC.

1.154? Big ouch. I hope that's not too high to be competitive. Mills / King 40 down around 1.120, faster upwind and a little slower downwind than a Syd 40. Syd 38 down around 1.110, and it's the same hull with a little bit sawn off the back...

It will come down further. The Syd40 tuf-luf used to drive is down to 1.139 or something.

I reckon I'll be down around 1.14X once I run through a few other options.

I think it will be competitve. No bandit, but competitive enough for a 13 year old IMS boat. No illusions as to being able to beat the high-end programs. The aim is to be competitve with the rest of the boats and have a load of fun.

Yeah those numbers make her look pretty nice upwind. If of course they end up being true.

We reckon we are going to come in under ex-Babe and under High Anxiety - so about 1.154

We are also looking at sail plan changes.

I'm done with exploring the rig changes for now and have refurbed / replaced the existing rig and rigging and kept it as standard. I think its a good setup as long as I can get the tuning right.

1.154? Big ouch. I hope that's not too high to be competitive. Mills / King 40 down around 1.120, faster upwind and a little slower downwind than a Syd 40. Syd 38 down around 1.110, and it's the same hull with a little bit sawn off the back...


It will come down further. The Syd40 tuf-luf used to drive is down to 1.139 or something.

I reckon I'll be down around 1.14X once I run through a few other options.

I think it will be competitve. No bandit, but competitive enough for a 13 year old IMS boat. No illusions as to being able to beat the high-end programs. The aim is to be competitve with the rest of the boats and have a load of fun.

Fast moded Cookson 12s are around 1.145, and you'll be faster upwind so that's not a bad number, though I don't think there are any in your neck of the woods. If you can get it below 1.140 you'll be in a good place I reckon. Our soon to be ex Cookson 12 does upwind numbers maybe 0.1 slower than your forecasts but rates 1.122, and is probably 6-700kg lighter.

An update from me. This is the new keel. It's now on the boat. It has trimmed the boat totally differently.

Looking forward to next year.

Awesome!! Go the Loco SYD40 programme!!

BTW - my old SYD40 was still fighting like a frickin' honey-badger against us (King40) and a Ker GTS43 over 10+ races in the past two regattas in Singapore...from 7 to 17 knots of wind too. The boat is still a great IRC yacht if tickled properly.

Owner is adding a prodder and a vee-berth in the forepeak next.

Cheers Tuffie.

This year was a write-off. Keel took WAAAAY too long so we got nothing in this year!

Yeah we are looking at a prodder at present. I was thinking of a selden removable thing but have decided just to build one I think.
We have a v birth forward - though I'm looking to change that to some composite instead of the heavy wood and plywood it is now.
Moving the fuel tank aft as well....

And then that is it for now I think.... OH except I am also considering converting to a tiller....

But none of these changes are going to stop me next year like the keel did... priority is now to get out there....

Does anyone know the owner of babe?

And in particular the original owner who won the transpac when it was called bull?

This boat seems to be the closest to my setup with rig and keel....

I'm looking for tuning information....

Hello,

In Netherlands I found ad that yacht Sydney 40 'Arbitrator' is for sale. I'm interested in that boat, but I have problems with finding info about this boat's history (eg. races it took part, wins, photos or previous owners). When I type "Sydney 40" or "Arbitrator" to google there's few matches, but I still don't know is it right boat. Sail number is GBR 4099. Is it possible, that anyone would give me a tip where to look for that boat's history.

Sail number GBR 4099

link to the broker's site
http://www.bachyacht..._40_aid-818.htm
Now the boat status is "sold", but I still searching for the data

Thanks in advance for help

Is that including a prodder/over length spin pole? (although I'll find out on Sat)

Also have you seen the aftermarket bowsprit on Phosphorous down at HYS? They had that fitted last year and use an A3 and code zero offshore to some success. With the new rating you now rate almost exactly the same as them and the boats are of fairly similar vintage.

Hi Tom,

That includes a prodder. A somewhat ugly thing that we are testing - sits onthe deck and is retractable. Although we've made a custom fitting onthe stem for it.

If season goes well and we make the permanent move to prodder we'll put something permanent on.

Phosperous is very similar. Except we have slightly more beam, LOA and are 1150kg lighter! Same upwind sail areas. (well close. Main is the same and we are 3 square metres smaller on the jib).

See you on Saturday.

I think you'll find the Cookson at least 500kg lighter, shorter and less rag. Sydney 40's rate badly. Cookson after the 2012 adjustment are nearly bandits.

The cookson 12's I've seen online are all 5500kg and above and mostly about 5800kg.

Mine is 5293kg. Just been weighed.

So you're saying cookson 12's are 4800kg and lighter?

Maybe I've found the wrong boats?

Yes we sail very well to 1.112, plenty of race and series wins to show for it. Last year's IRC rating was 1.122 (no change to the boat) - and we won at that too, though obviously not so easily. Our empty boat weight is 5025, IRC DLR is 138, yours is 140 so you're heavier. AFAIK all the C12s are around 5 tonnes empty +/- The original Farr Design 336 race boat was down around 4700kg but the C12s have cruising interiors similar to the Sydney 38 in style, for example we have an oven, a fridge and a hot water shower. MAT 1245 interior is pretty much identical to ours in specs.

There was a MAT 1245 racing in a regatta in Sydney last week at 1.140, we weren't on the race course but the boats we usually beat were and they beat the MAT pretty solidly. We haven't sailed against it yet.

Lightweight new style 40s obviously rate much higher = Ker 40 around 1 18-1.20 for example, and Carkeek 40etc above that but they are stripped out light displacement racers that can easily outsail their single IRC number in solid breeze reaching and downwind and given relatively high stability they manage upwind too. They are sticky dead downwind in the light stuff. We can sail boat for boat with a Ker 40 dead downwind below about 8 knots - we run S kites. Heavy boats like the MAT / King 40 etc struggle to sail to big IRC numbers offshore - they just don't catch waves easily.

I wonder what boats I was looking at.

Unless the specs were a typo.

Here's a rule of thumb calculation as to how the Syd 40 ought to rate against a C12. Given that the DLRs of the two boats are effectively the same they will have the same propensity to surf - they're approximately the same length and hull form. So we assume the ratings of the boats should be proportional to their hull speeds, which is proportional to the square root of the length of the boats (more or less...similar hull forms and DLR) So, multiply the C12 IRC number by the ratio of the square root of the lengths and you get around 1.135 as a target number.

As I said all this is very rough rule of thumb stuff...if the Syd 40 is much more stripped out, stable and hits higher upwind and reaching numbers as a result then perhaps a higher rating is workable. Our hull factor is 10.6 IIRC. Downwind, extra spinnaker and main area won't make a huge difference most of the time - we hold our own with later model C12s with bigger rigs except in marginal surfing conditions. A Ker 40's spinnakers are 40% bigger than ours yet we hold them in the light.

Interesting calculation Mr Dastardly.

We are pretty trim. I think we could lose another 50-100kg's - by removing cot berths and forward berth, but we've just dropped 200kg's somehow (ballast difference was only 50kg's)
We have the best righting the hull can handle (tbh i sometimes think maybe i should have undertaken some strengthening and gone for more)

Our Hull factor is 10.5. Rig factor 1.034.

We've gone for a temporary prodder and a-sails to test - under advice from Dovell - since its a fastnet year.

Considering when i got her the rating was 1.175! I was happy with 1.144. Like I said i think we have a chance of sailing to it. But now I wonder! It could be worse. We'll be very close to the farr40 around the course and the farr racing in the spring series is 1.166!

Either way. With all the changes she's fun to sail. And we'll have a good season.

Here's my weekend's work, another one wrapped up. Very satisfying beating the Ker 40 to the turning mark. We run a short prodder and a slightly overlength pole. We use a Code zero that's around 75% spinnaker size, largely in place of a jib top and it's been a winner - filling the hole in the polars between the short foot jib and kites very well. Stability isn't the Cookson 12's strong suit, so it's fractional and size limited. Syd 38 is way more stable and hence Syd 40 too I'd suspect.

Well done.

We were second on the weekend. Only 4 boats started though!

Done by Tokoloshe by 3 minutes.. 3rd and 4th were well back by about 10 minutes.

Hard to tell how far away from competitive we are. Loads of areas where we definitely can pick up 3 minutes. But then Tokoloshe wasn't flawless either.

Interesting...and well done!

I've seen them go up for adding prodder too. Has to do with alot more than just add/not add as boat type/age/sails/overhangs etc come into play.

Does this boat have running backstays?

No runners. 2 spreader carbon mast. The pole was already overlength at about 112% J and the prodder is carefully sized to be no longer than that so nothing changed. The boat has an IRC DLR of 138 which to a large extent defines its downwind performance, coupled with the available stability. Based on the courses we sail and the competition we deal with we chose that config. We fly the code zero off the prodder and also an 80% A-sail for big days downwind - but we previously flew that off the pole in any case. We're not yet convinced we need a full size A sail.

As it is we are better than the Ker 40 downwind in the light. Their kites are 40% bigger than ours and they are a bout 200kg lighter and a lot more stable - their ORCi VCGM is 700+mm lower than ours and their RM a third bigger. They sail huge angles downwind in the light. Reaching, however, they utterly smash us once the breeze is up over about 7 knots - they sail well faster than their IRC rating in that direction. Upwind we beat them in the light, they smash us in breeze.

Haven't raced the local MAT 1245 yet but they raced some of our competition (boats we beat regularly) a couple of weeks ago and got beaten - though fairly it was that crew's first serious sail in the boat (good crew though). But a heavy 40 footer rating 1.14 doesn't make a lotta sense to me for these waters.

If we were sailing in Singapore, or on the Asian circuit things might be altogether different however.

Seems to me generally that a purely A-sail boat needs to be able to sail pretty fast to draw the AWA far enough forward to get decent gybe angles downwind against a S-sail equipped boat. That means light displacement and plenty of stability in mid-high wind strengths, in the light it means low wetted surface and light displacement.

No runners. 2 spreader carbon mast. The pole was already overlength at about 112% J and the prodder is carefully sized to be no longer than that so nothing changed.

Cookson 12 along with Farr 40s were the beneficiaries of some IRC largess to boats below IRC DLR 140 last year which helped their cause dramatically.

The Ker 40s seem to me to be a bit in no mans land a bit too heavy to be a light weight flier and too light to be the beneficiary of IRC caravan preference. I think they should have gone lighter and try to get the IRC DLR down into the 80's which would give them the advantage of being in another area of IRC largess and also able to pull the apparents forward.

Does this mean you no longer use a pole? Is your 80% A sail your biggest spinnaker? HAve you sailed in any W/L races lately?

No we use a pole most of the time. We only have the one A kite in the inventory plus a code zero. Our S kites are all oversize - about 25% bigger than those originally envisaged for the boat. It's all on the ORCi certificate... We do just fine in W/L racing. A bit short on stability uphill in heavy airs but fine otherwise. Big gains downhill sailing fast and low.

True we did benefit from the last round of IRC changes, but we were winning at 1.122 - but obviously less easily. At 1.112 we are very competitive.

I sense the Ker 40 is generally competitive, around here it's only in the light it struggles and I'm not sure that's a DLR issue. I'd doubt the Carkerk 40 style boats could deal too well with the local conditions. Heavy airs upwind I'd be sceptical as to how they would fare.

Interesting calculation Mr Dastardly.

We are pretty trim. I think we could lose another 50-100kg's - by removing cot berths and forward berth, but we've just dropped 200kg's somehow (ballast difference was only 50kg's)
We have the best righting the hull can handle (tbh i sometimes think maybe i should have undertaken some strengthening and gone for more)

Our Hull factor is 10.5. Rig factor 1.034.

We've gone for a temporary prodder and a-sails to test - under advice from Dovell - since its a fastnet year.

Considering when i got her the rating was 1.175! I was happy with 1.144. Like I said i think we have a chance of sailing to it. But now I wonder! It could be worse. We'll be very close to the farr40 around the course and the farr racing in the spring series is 1.166!

Either way. With all the changes she's fun to sail. And we'll have a good season.

Enjoy.
Here's my weekend's work, another one wrapped up. Very satisfying beating the Ker 40 to the turning mark. We run a short prodder and a slightly overlength pole. We use a Code zero that's around 75% spinnaker size, largely in place of a jib top and it's been a winner - filling the hole in the polars between the short foot jib and kites very well. Stability isn't the Cookson 12's strong suit, so it's fractional and size limited. Syd 38 is way more stable and hence Syd 40 too I'd suspect.

Interesting your comments about stability, the S38 having an all lead keel and a pile of timber inside has a fairly high VCGM of -0.0005 RM is 164.4 would not have thought the C12 would be much worse.

But the 1.112 rating is pretty good, we rate 1.105 and are 700kg heavier, hull factor 9.8, shorter, alloy rig and I suspect less sail area. Hard to see why we dont rate a fair bit lower, we don't do too bad on IRC, but hard to win against purpose built IRC boats.

If you put 4 rating certificates of roughly equivalent boats side by side and tried to explain the differences you would would need to be a pretty good story teller to come up with a reason. Take a C12 and S38 certificate and compare it to a Z39 and try to figure out the Z39 rating.

Dart board stuff and they will not admit errors.

Our RM is 141. Rig size is about the same as a S38. Later C12s have deeper keels and taller rigs but they rate around 1.135 and never beat us.

S38 is much wider on the waterline.

Coming from the bloke who said he didn't think a Zero would work on the cookson!!! Well done on another series win DD.

BS - it was my idea in the first place. Just told the owner and sailmaker to be careful as the boat has limited stability and couldn't in a pink fit exploit a big zero successfully. Proven. That said, the sail is a glamour - the polars look great now!

Good to see Ollie found your password...nice to see you back in circulation.
