Yes Timberwolf is definitely still for sale
If anyone wants a quick boat very well capable of winning Division 7 in the Coastal Classic then this is the boat for you
New rig offers even better light air performance.

Finally some progress. New carbon mast section underway for Timberwolf
Many thanks to Adrian Pawson for his help on getting me some of the Intermediate Modulus Fibre we are using

Here is the best photo I have of the most awesome boat you could ever dream of owning.
Through Timberwolf I have met some amazing friends and in Bryan Roberts a great friend who has stuck by me and the Wolf every step of the way.
This Photo shows Bryan and I competing in the last Simrad race.
As you can see I was pushing the boat far too hard, and as Tim Clissold likes to say I was "sailing it like I'd stolen it", but during the leg to Channel Island we had smoked past Charleston , Taeping and also Wired and only had 888 ahead of us.
You bet I pushed the boat hard, and sailed it in all sorts of conditions, and took it out whenever I could.
I did it because I loved it.
Timberwolf thank you for the amazing friends and awesome memories, I hope your new owner will love you just as much as I have.
Next step for me is to finish off my A Class cat and hopefully get to sail in the next Worlds being sailed off Takapuna next year.
Timberwolf is currently on the Hard Stand at Little Shoal Bay for the Winter and is available for a short time only in her current condition.
I have purchased an Extreme 40 mainsail (3DL) which has been cut down to suit and around which I will be designing and building a new carbon Hall Spars mast for Timberwolf.
The boat will be returned fully to sailing trim by next Summer.

Timberwolf can be purchased either in As is Where is condition or if required I can build a new taller rig, fit new rigging and halyards as required, as well as fit new Main and #1 Jib.
Timberwolf will also be on view at the NZMYC Boat Show on Sunday 17th March from 9-00 til 4-00 near Team NZ base at Wynyard Quarter in the Viaduct.

Unfortunately diamond stays broke on way back from Route 66 and mast came crashing down. Mast broken into 3 pieces and main torn to shreds. Minor damage to starboard AMA and rudder. All halyards destroyed and some rigging unusable.
Just had the best few weeks with my beloved Timberwolf we won the Te Kouma race by the distance from Shag Island to the finish and we won the Coastal Route 66 race in fine style. Our last sqaddy race on Wednesday was our best for a while and we had a nice handicap win.
Someone else needs to own this beautiful boat. Timberwolf will reward you every time you sail it.
I bought it to win the Coastal and if you want great results at a fast pace the. This is a great boat for you.
I am gutted but Timberwolf just has to go.

So were you running any foil Tim?
Yep foil fully down but at time of capsize we may have been going too slow to develop much lift and/or it let go
Another cock up was that we didn't have the rig canted as its usually too hard to get downwind when it is canted, but at this time if we'd been fully canted it probably wouldn't have happened
-
Good to hear no damage to people or boat.
Tim, some more details please, this flipping thing may be a whole lot more fun than it looks but I'd like avoid it if I can... for as long as possible. The current technique of not going out in non-glamour weather works well but isn't so satisfying.
Point of sail?
Forwards or sideways flip?
Lessons learnt etc
Step One:
You can't have fun sailing your boat or tipping it over for that matter if it is tied up to the dock.
Step two:
If conditions are too strong for you or your boat see step one!
To me this wasn't a day I had thought we would be at any capsize risk. It was around 20-25 knots most of the time before the start. We had a Reef in the main and small jib which I thought was very conservative. The forecast was for the wind to drop in the afternoon and evening.
Sometime after the start we were doing the usual Downwind Rum Race Wallow where we really needed an extra up to make it fun and we were contemplating cracking our first beer we got a couple of little wake up gusts where we squirted up in speed to Mid 20's but at 140 degrees true we were broad reaching with no real dramas.
As we got closer to Mechanics Bay and after the Container terminal the Breeze freshened and came forward such that we were more like 120 degrees true and right on the death angle. To depower I could just feather the front of the main and jib and this was very safe and no bother at all.
However we were sailing higher than our actual course to Orakei and in the puffs were pointing more at the Rescue Centre end of the breakwater.
As the Gusts were usually short and sharp I just thought we'd wait a little then bear off to the mark.
At the time we sailed for probably 5 minutes going in the wrong direction.
My options were to Reef the main, or Drop the Jib and I was considering Pulling out as I wasn't sure sailing in these conditions across to the Rangi shore was such a good idea.
The Wind appeared to ease and I thought iot would be safe to bear away to below our course to Orakei as we'd be below the Death angle and could just bear away to depower.
Anyway we never made it the second I tried to bear away we tipped over.
The Lee ama went in to the beam and the boat corkscrewed round as in a broach so we ended up capsizing pretty much on the diagonal.
In hindsight I'm convinced we had too much mainsheet on and needed more twist in the head of the main.
Our capsize plan worked very well.
I tied in the Rudders
Then opened the aft ama Inspection hatches to flood the aft ama section behind the beam.
We attached a bridle to the Heavy Padeyes I had put on the deck in front of the main beam.
Ken and I had our weight right at the back sitting on the ama as they towed us backwards, going across the wind.
The back started to sink, and 90 seconds later we were upright.
Full credit to the Police guys they did an awesome job righting Us.
No damage as it all happened so fast and very little gear had a time to float away.

Well here is a great shot of Timberwolf doing exactly what I one day hoped it would, crossing the finish line first at Russell.
Once again my sincere thanks to all of you who helped me get the boat to the stage its at.
Our next goal has to do with a record !

Hi Tim, you said in other thread that you damaged the mast beam. I had a look from the dock on Saturday, I've got to be honest it doesn't look like the damage will just buff out. how serious is it? will it threaten your coastal.
There are two parts to the beam. A non structural fairing on the front and a box shaped structural part at the back. There has been a small amount of movement since relaunch and the fairing has cracked a bit and there is some slight damage to the structural beam and socket after the Simrad but it is very minor and is extremely easy to fix and once done it will be significantly stronger than it is now so I'm not expecting it to give us any more trouble albeit it was probably not smart pushing Timberwolf that hard in such massive seas, we should have put in another reef sooner.
The boat will be repaired and re antifouled in a xcouple of weeks time and we are looking forward to the Coastal.

I'd suggest that if you have to have wood in a foil then you need to use the strongest orientation of the grain to prevent a hull exit compression failure. It would be more efficient to use it like end grain balsa, ie with the grain running the shortest distance between the carbon flanges.
The contribution of the cedar to longitudinal strength and stiffness compared to the carbon content is minimal.
Using the cedar along the foil is relying on its core sheer strength. Remember how you split fire wood, along the grain. Imagine a plank lay up of a cedar core boat without the glass either side; it would be easy to break.
More efficient again would have been a double bias sheer web.
Wood has as much place in a carbon foil as aluminium in the marine environment...
Oh my god, no ! Tim Clissold was 100% right.
We broke the new board.
Compression failure of the core.... aaaaaaargh.
Was probably not too happy dropping off 6m odd swells at Channel Island so decided to bust off and head off to Cape Colville.
Absolutely no wood in the new board.
It has a HD foam and carbon shear web in the centre in place of the cedar.
However despite having to eat humble pie on this aspect i will NOT be removing my boom, buying a Sail Outboard motor or importing a Cheap chinese wind generator fan that doesn't spin and is fitted in such a way that with too many people aboard the water gets in through the electrical wiring hole and boat begins to sink.....
-
The Upshot with the Jammers is that the Plastic XTS Jammers have 20% less holding than the XCS model and even though I cannot believe our 3:1 stays ever see 3 tonnes (and therefore the Jammer 1 tonne) I have decided to go for the upgraded model (which allows an extra 600kg on the sidestay).
That should fix that !
-
wouldn't you have a safety strop fitted in line somewhere - in the same vein as a swimsaver on a windsurfer
Sure do have a safety, that is what stopped the rig falling over the side completely.
-
Tim could you talk to us a the leeward cant during the first part of the race on Saturday, between the start and devonport.
Not sure if thats your normal sailing position or a case of not remembering to cant it before the start (to windward)
Well spotted.
The little Cam in the Spinlock Jammer which is held against the Rope by a little spring when the clutch handle is closed kept lifting off the Rope on Port tack.
I think the Spring needs replacing?
Anyway that meant we had to sail to North head canted to leeward until we could tack and then fix the problem.
I took it in to Sailors Corner and Pedro said they have had a few customers bringing in their Spinlock XTS Jammers having the same problem.
Very scary for us as we are relying on the jammer to hold the rig up!

A technical question. With your rudders on the TW would you expect the loads on them to be higher or lower than a mono of an equivalent size?
I was pondering if they would be higher or lower and buggered if I could work out which it would be. I'm thinking 'generally most of the time' less but would 'spike' higher.
I did like that snippet of vid peanut took of last weekend.... including the comment heard 'it'll be close'
Compared to either Positive Touch or Fun n Games both Light Displacement 30' keelboats the loads on Timberwolfs rudders are around half to 2/3rds the loads of the two keelboats.
I Know this as we built Positive Touch a rudder blade slightly stronger than Timberwolfs and it broke in the Coastal they were leading. I then used the laminate of Fun n Games' rudder to beef up Positive Touch's rudder and stock and I understand its still going strong today.
The Blade of Timberwolfs Rudder is about 7 kg, the upgraded PT rudder more like 11kg.
For a further indication take a look at either X Factor or Taepings rudders. Both are very similar to timberwolfs but are really very thin and light looking, you can't even compare them to Rudders on either a 44' or 52' monohull.
The reason for this is due to the tracking nature of Multihulls.
Put a long skinny hull in the water and try to turn it.
It really just wants to keep going straight. Hence turns on Multihulls are long slow arcs.
The "broaching" of a keelboat and the rudder over at 45 degrees is when a monohull rudder sees its biggest load and you can't duplicate that in a Multihull.
If you were to consider grounding the rudder as well (the mode of failure of one of Timberwolfs) then once again the multihull sees less load this time due to the weight of the boat. In the case of Timberwolf its about 1200kg or so, whereas either PT or FNG are more likely to be around 2000kg I'd guess.

New transom for both hulls incorporating new Carbon Gudgeons.
The new Gudgeons are mounted from the Inside of the transom through angled holes.
Inside the Transom they are Glassed over and the photo shows the Carbon over the new Gudgeon.
The Old gudgeons had peeled off the Old transom, on the Starboard side we hit the bottom soon after the relaunch.
The Port side fell off the Friday before last when we backed it into a mooring post. I glued it up quickly that night to do the Windward Leewards the next day but actually the Glue hadn't been properly mixed and it was probably too cold, anyway that is the one that fell off during Simrad.
Inside ther transom are some flanges and a knee down the centre, so by grinding off the old transom I can get back to that. (Next fine day). Then will glue the new transom on each side and tidy it up for racing on Saturday.
The boat has to come out in September for re antifoul and then I will have the chance to tape around the back of the transom and touch up the Paintwork.

Are you using the canting system at all?
On every leg on saturday we used about 10 degrees cant.
Have found upwind we start canting the rig in 12-15 knots.
Downwind (running) we don't cant below 20-25 knots.
Canting the rig depowers the boat so you use it if you are overpowered.

New mast finished cooking and now ready for fit out and painting.
There's not a lot of work to get the Wolf sailing again so anyone keen on doing this years Coastal Classic in their own ultra fast Trimaran should get in touch soon!
