If a new Marina was built today would they even bother with 9.5 or 10.5 M berths ? probably the smallest would be 12 or 12.5 M, sometimes I think the classic 8.8 metre Gulf Cruiser Racer of the 1980's is now akin to a Bavaria 38 or similar

Marina Type ExamplesTypical Occupation Model Private Commercial Bayswater Pine Harbour, Hobsonville Private berth ownership or commercial rental.Charitable Trust Half Moon Bay, Orakei Berth licenses held by individuals; profits reinvested.Auckland Council Westhaven, Viaduct, Silo Moving toward 100% rental models as historical licenses expire (e.g., Westhaven in September 2026)

If you have a lines drawing it is fairly easy to make a half model if you get stuck for the original.

@MCP, thx for suggestion to use Parts4engines , they have the seals I need If anyone has used them, what's the story with shipping as all options say that tax is payable on arrival, do I get a call from Customs saying pay the GST or ....? chrs

Here are photos of the damage, I think the feedback was a bit ambiguous, it looks like the adapter plate bolts came loose not the flywheel attach bolts which seem fine. I need HEAD GASKET · F/TIMING COVER GASKET · ROCKER GASKET · FRONT & REAR SEAL · REPLACEMENT ADAPTER PLATE BOLTS · WATER PUMP GASKET · SUMP GASKET Might need to buy a full seal kit if possible, the ones online involve a full overhaul kit including pistons and rings ! @ $750 (parts 4 engines) need to do a bit of phoning around on

I'll get them to use loctite for the reassembly but also see if I can get a copy of the shop manual and see if it specifies lock washers. Annoyed that it happened but yes the outcome is a huge relief, we will probably get it back in action for March/April ....yay ! Haven't missed much with the recent weather anyhoo.

Did I say Massive sigh of relief

I wont keep you all in suspenders any further ........................it was............................!!!!!!!!!!!!! The bolts that attach the flywheel to a flange on the crankshaft had unwound themselves yes all of them! eventually they contacted the bell housing, ie clunk-stop. The rebuilders reckon they weren't properly torqued at the factory, no harm to the engine , they had taken the head off as a precaution but nothing wrong there. I just have to source a few gaskets for them and its all go , hopefully the bill won't be too steep for that, they said its a very common engi

DRUM ROLL PLEASE ............................!!!

That will buff right out !

They must be using materials other than Cardboard, and Cardboard derivatives or string sellotape and rubber etc all banned.

Nathan is an Ozzie isn't he ?, regardless we will claim him if he does well.

You might have to if they cant fix the damage in time, apparently the stern fell off but they recovered it before it left the environment. Perhaps they will borrow from F1 and deploy a pace boat to slow the field allowing on water marshals to clear debris and recover damaged boats before racing recommences

Yep, on the tighter courses with a fresh breeze I think pretty much all of the boats are experiencing at least one near miss and a few are having a F*^k me where did you come from !!!! moment like when you accelerate briskly out of a car park before narrowly missing the car neatly obscured behind the A pillar .

From the post race interviews Ashby, Slingsby ,Grael,Robertson, Burling and Schneiter expressed general anxiety about near misses at speed and the craziness of increasingly competitive boats all jamming into the first mark on a tight course. Burling in particular appeared shaken noting that the Bow of the Swiss boat missed him by a metre. I guess a bit of crash n bash is a good blood spectacle for the promoters and fans but to me these boats are not suited to being used as bumper boats , way too fragile. Let's hope that there isn't a fatality at some stage then the organizers would certainly

Watching the replay Its weird that NZ didn't anticipate the likelihood of the Swiss tacking, seems a basic error ....frustrating !

No visual signs of water contamination in the oil, likewise no visible indications of the engine making metal but to be fair the oil hasn't been lab analysed. My son was solo on the boat at the time but as far as I can tell none of the usual signs of advanced bearing failure presented although its possible they were there but not obvious or noticed. I dropped the engine off at the rebuilders last tuesday but it will be at least another week before they tear it down, standby to standby.

No updates at this time: My son was on the boat at the time but he reports there were no unusual sounds or symptoms other than the sudden clunk, yes I'm wondering about the timing gears/chain too but I'm not sure which it has, in any case I would not have thought a complete lock up would result from that ( I could be wrong) . The biggest metal impeller is the prop and its fine as with the saildrive unit. One thing I should have removed was the bell housing cover to see if the flywheel was somehow locked up. Really the only thing confirmed thus far is its the engine not the gearbox.

I popped the sump and no metal particles or any visual indication of damage/failure, everything looked normal. I could see the intake valves through the induction ports and there was no sign of rust or moisture ingress. . The engine was idling at the time of failure but I suppose if there is some way the exhaust mass flow could be overcome by a water column in the exhaust then that might be a cause although the current exhaust arrangement has not altered in 25 years of use and has never caused any issues. I'm assuming after a hydrolock the engine could be turned even a little with a big spann

UPDATE: Nothing unusual under the rocker cover, likewise starter motor pinion and ring gear look normal. Got on the phone to the tech at Volvo and he concludes that only a seized big end or Crank Bearing could cause it to lock up with zero lash ie all other possible culprits would exhibit at least 2 or 3mm of rotation on the crank pulley. Can't see any bad reports on the interweb with Shibaura engines in fact they are considered the epitome of rugged reliability such that even Kubota use them in some products. So its into the shop it goes and we shall see, but I will update, probably in

My old metallurgy tutor called it Differential Oxygenation, ie oxygen rich at the ends (Cathode) and as you say starved in the middle (Anode) all you need then is some electrolyte as present in damp wood and bingo you have an electrochemical cell !

Wasn't Ceramco's rig brought down by a lack of toggles at the spreaders ? it was rod rigging as I recall and failed due to fatigue.

Here is a stainless bolt that has been buried in structure for many years , it would have looked to be perfectly sound at either end when installed. Probably best to treat buried rigging fittings with equal caution IMHO, after 40 years at least remove and x-ray or otherwise just replace it and sleep easy.

In my old life in aviation we would sometimes call that dull middle bit the fast fracture zone where the crack propagated at speed to final failure. The striations either side of that we regarded as fracture progress lines created as the crack propagated,probably over some years. Yes it certainly started at the thread root but it's hard to imagine where the cyclic loading is coming from, perhaps the furler ? There was an article in Boating NZ many years ago where some owner paid to have his rigging x-rayed, visually everything looked fine but the x-ray showed cracking inside seve

The Propellor spins freely with the gearbox in neutral and the gearbox/saildrive oil level is normal, oil presents normal. Hauling out on the weekend and will split the box from the engine and we will know which half is the cause , I will post the results . As for CGA, the engine/saildrive was new in the crate purchased 10 years ago for a boat then being built DIY. The project was never completed and the owner started selling off the bits. We installed the engine four years ago and we had to disassemble the crate first. I checked with the Volvo techs as to what procedures to adopt an
