What comes around goes around cause the new owner of the Shuttleworth is the old owner of TL Systems!

"weather models often disagreeing and very short windows...many boats up there still waiting now"
Could it be a result of too much information. In the past you got one forecast (maybe) and then picked your best guess and just went....
Now we get overloaded with detail and can't make a decision.

Re Erice's foto, The ring gear on the flywheel suggests there is a starter motor tucked in the back side, you can see something poking out.. I doubt if it was electric but it could be??? I thought these big engines were started using compressed air directly into the combustion chamber..... am I wrong??

Funlover, Many of the boat sailed out of Fremantle in WA have this type of lifting keel and the two I sailed both had 2 x large horizontal pins that were pushed through the case and top part of the keel when it was down, locking it in place. And yes some water came in, but not much. Actually the positive fixing is required by the rules so it can not retract during a severe knockdown. To hold it up a webbing strop could be attached once it was fully raised (the head came out of the deck into a sort of house) but often wasn't, they just relied on the hydraulics to hold it up.

" in fact they are not as clever as the top end B&G models"
NKE developed very clever systems for the big solo trimarans that "know" enough to, for example, bear away when overpowered off the wind, and also release sheets when required, but not when not needed to, clever stuff indeed. So the solo sailor never needs to steer.

Plus 5% tax plus GST adds up to nearly 22% because the GST is on the taxed total (and is supposed to included shipping costs as well).

I can't see any hatches in that picture, nor any winches or wheels, leads me to suspect it has been boarded and stripped. So if the hatches were still there it would have much less water inside and been floating even higher. Making it a highly survivable habitat

Interesting historic note, on a previous sand replacement programme, (maybe 6 or 7 years ago??) the sand was dug out of a sandhill in Golden Bay. The consent required remediation work following the "mining" which (remediation) was never done. The hole is still there but now disguised with "natural regeneration" = weeds. the council blames the contractor who probably doesn't care as there is or was no consequence. I wonder how the Oriental bay residents can consume their lattes on their golden beach without conscience.

On the 930, Redline, Stu cut the ends off the track so it stopped just past the cabin line. Saved quite a few shins. However the S/t jibs never set very well when reaching after that cause you can't get the car far enough out away from the centreline. I suspect the 830 is very similar to the 930?? Stu might have a photo, chime in Stu......

Steve, Is that import duty by Vanuatu or export by NZ customs???

Your are correct KM...m. For Redline we added those massive timber floors to spread the loads out and along the hull AND strengthened the chain plates and tied them down into the keel area. Very important because we increased the righting moment significantly.

Matt,
1366x768 and IE 11
I have only had this since the new format of crew.org was implemented

Hi KM..m, I don't know. Probably not because she was and is outboard powered in the well. Might have been a water tank perhaps? I didn't have much to do with her BKM (before keel mod).
Note that the new fin is made of high strength steel (bisplate 80) .... not mild steel.

I hate the way photos spill all over the screen so you have to scroll sideways and down to see it, it sucks.

Hi, On Redline (Ross 930) we had the flat outside plate with bolts for the original keel and for the new one I was not happy with the idea of hanging 900kg of lead off a 2.4m long fin with a flat plate to not much inside. So There is a stub that sticks up inside about 150mm and we poured epoxy resin around it between some new solid timber floors. I convinced Stu to go this way and it is solid!! think about holding a broom handle horizontal by somehow clinging to the very last 5mm compared to a whole fist full. Stu might chime in with more but he is in Russia at the moment.
First photo is original
Second is the new floors laid out
Third is finished job
Fourth is the bulb fitted to the alloy steel fin in the workshop
Fifth is my drawing of the concept.

John Ruskin wrote the below quote in the early 1800's, it is still just as valid today (perhaps more so).
“It's unwise to pay too much, but it's worse to pay too little. When
you pay too much, you lose a little money - that's all. When you pay
too little, you sometimes lose everything, because the thing you
bought was incapable of doing the thing it was bought to do. The
common law of business balance prohibits paying a little and getting a
lot - it can't be done. If you deal with the lowest bidder, it is well
to add something for the risk you run, and if you do that you will
have enough to pay for something better.” -
I have a number of photos, but being the luddite that I am was unable to post them, at least copy paste didn't work, no paste allowed (greyed out). Is there a link function other than the URL one which I thought was for web addresses, or is that what I should use?

I have many (~50) photos gathered and scanned over the years, what is the easiest way to post them all?

Not completely sure why you want everyone on board to have a radio but if you only want to be able to talk to the guys on the front of the boat without yelling at them (for example), then those cheap dick smith UHF radios would do the job, wouldnt they?
Certainly much cheaper than marine VHF and less likely to transmitt your crew secrets whisperings to everyone else in the fleet!!

You're probably right, as I mentioned above Trevor didn't place much value on them and if SD is correct (or was it coxcreek?) he never paid DB for them, so they will have been dumped. I had a poke around the back of what was Tropicana Fibreglass a couple of years ago but they were not obvious. Double Vision was moulded after Sundreamer but built like Stratosphere with vertical hulls .... and very blunt bows I thought.

The Napier built C2 ?? was called Double Vision. Was built by a fibreglass factory called Tropicana Fibreglass who mainly build pools and the like. The owner Trevor Cambell obtained the moulds from DB (he told me he bought them). Trevor was extremely scathing about the quality of the moulds, I think he epected to be able to mould a complete hull from one mould not make half a dozen pieces and have to stick them together. The boat was as someone said above overweight as it was built using a chopper gun. But it did have balsa core in the cabin top. It also had two volvo diesels in it.
It was fast by Napier standards holding an unofficial record for the Napier to Gisborne race. I think the time was around 7hours but I am not sure now. Trevor sold it overseas, I thought Florida and delivered her across the Pacific and through Panama Canal. The trampolines were a pulp dewatering fabric (like tough nylon fabloc with smaller holes), which I know beause I gave them to Trevor, I worked at the local pulpmill at the time and had a couple of the fabrics and was building my Tennant Firebird (for the first time) at the same time.

Snap shackle on an adjustable bight

Only comment I would make is that if you go back to the block or where it is with the tack line end you may not stop the loop spinning and hence the furler from rotating. You need a little bit of separation between to two legs of the bight so ... make a loop in the end of the tack line and put it around the prod, ideally 100mm or so away from the block, use a saddle or something to keep it there.
If the furler spins it quickly becomes a cluster F..k
