Tough call , sort of damned if you do or damned if you don’t subsidise a private refinery company to the tune of 230 million PA just to break even . And how do you subsidise a company that doesn’t want to continue refining ? Just take over the joint and tell them to fuck off ? . They clearly stated they didn’t want Govt intervention and didn’t want to continue with the refining model . But there is a chance they could keep refining because of the crisis ? Doubt they have started putting plant in the bin just yet ?

Marsden point has been shut down for refining and an inside source (good friend) tells me that the process is effectively irreversible. It was never planned with an option to potentially recommission again in the future. It would basically be a new build. Which isn’t surprising given it’s decades old anyway.

i see our dollar is steadily going south... BNZ predict its heading for the Auckland islands or thereabouts so i can't see our shipments of fuel getting cheaper anytime soon. Could be time to discretely stock up a bit if you haven't already. Does anyone know how often these ships arrive? imagine the drama if for some reason they give us a miss

I look forward to smaller wakes as higher prices affect even the Riv brigade. On Sunday I saw a a fuckoff big sport boat (game fisher ) at around 90 foot heading over the horizon behind the poor knights (Fiji ?) doing about 15 knots + . on Monday I saw a very big launch about 60-70 foot looked like a Viking , doing sub 10 knots heading north hugging the coast . My takeaway is the Uber rich can still open her up but the very rich are keeping it off the plane to save diesel $$.

Could be time to discretely stock up a bit if you haven't already. Does anyone know how often these ships arrive? imagine the drama if for some reason they give us a miss I think the thing people are going to struggle with here, is the concept that petrol can get any more expensive... The fuel light was on in both our cars this weekend. I have been joking that I need to phone the bank manager and get the mortgage extended before I can fill up. A few weeks ago people would laugh at that as a joke. Now they ask who I bank with and if I've got any good tips on getting the mortgage extended... I've not been following exchange rates lately, but yeah, it is looking rather shabby. The price of a barrel of crude doesn't look that high to me. I always though $120 US was a high threshold. I guess we are getting done because of the exchange rate on top of $100 / barrel prices. Oh, and all the GST and Auckland taxes that make up the $3.25 / l. If the govt take 25 cents / litre off, then the price goes up a dollar anyway, they are making 15 cents / litre more in GST, so they have really only dropped the price by 10 cents / litre. Good old smoke and mirrors. The oil producing nations must be wee-ing their pants. Shame we aren't one anymore. Wonder if ACT / National will reverse the prospecting ban, and how long it would take to find and develop a new field in NZ. That said, now we don't have a refinery, so I'm buggered if I know what we would do with crude oil now. Might just have to get a solar array for the house and bigger EV batteries. As long as the Greens don't work out how to tax wind (along with cows and utes), at least we can still go sailing.

drove past the local Gull today, diesel 2cents more than petrol, then of course you have to add the RUC's. Diesel car owners will be spitting nails and I think it will get worse as the Northern Hemisphere goes into winter and the demand for heating oil ramps up.

Diesel car owners will be spitting nails and I think it will get worse as the Northern Hemisphere goes into winter and the demand for heating oil ramps up. I got 60 l of diesel today for the boat. Picked it up in my hybrid... Pump price was $2.80, less the discount I get via my fuel card account. I need to check what it is on diesel but it's somewhere between 12 cents and 24 cents a litre. I deliberately chose not to look at the dollars on the pump, just the litres. That lot should last me through till at least Christmas though, considering I burn 4 l/hr if motoring, and it's a sailing boat.

I doubt if you use even that much, my long term average on a 56hp Yanmar is approx 2.5l/hr and that includes 80hrs motoring to Tonga and 75 hrs back from New Cal

I doubt if you use even that much, my long term average on a 56hp Yanmar is approx 2.5l/hr and that includes 80hrs motoring to Tonga and 75 hrs back from New Cal That is interesting. What revs to you cruise at? Max rev's for my beta 35 is 2,800, and the fuel burn curve says 6l/hr at 2,800. I tend to cruise at about 2,400 to 2,500. At 2,400 the fuel curve says 4 l/hr. These revs are above the peak torque and where the fuel born curve starts steepening up. if I were doing a long distance cruise, like to Tonga, I'd run at not higher than 2,000 rpm, just on or above peak torque which is about 2,050 rpm But I'm basing my 4 l/hr on how much fuel I used divided by engine hours (i.e. actual fuel use). I used to use 3 l/s for trip planning, but now use 4 l/hr. Noting that I want to be realistic but a tad conservative for trip planning. My last long cruise we averaged 3.75 l/hr over 50 litres. So that includes puttering out of the river, stooging slowly around anchorages looking for a good spot, and motoring from the River to Tiri and back (it was a glassy calm week, good for the kids, not good for sailing). My engine is still basically brand new, 120 hrs on it. We used to plan for 3 l/hr on my old Izuzu 3AB1, but that was cause the thing was so noisy and shook so much we never really brought it above about 1,800 rpm.

We used to plan for 3 l/hr on my old Izuzu 3AB1, but that was cause the thing was so noisy and shook so much we never really brought it above about 1,800 rpm. OK, running at those revs on Charlatan and guessing her speed length ratio, probably around 1.2 (speed/Sq rt LWL in feet) I can understand the consumption. CZ obviously has the extra LWL, about 40'. Her prop is slightly overpitched so she only reaches 2800 rpm. At those revs she is doing 8.4 kts (exactly as calculated), bow is up in the air, swim step under water and feels like she could get on the plane with more power Regular cruise around the gulf in 7kts @ 2000 RPM (clean bottom). On the long trips I drop back to 1800 rpm. I had the exhaust elbow off last year after ~ 1000hrs and it was clean as. Halberg Rassy publish engine performance data for their yachts, this is for the HR 40 which has the same engine as CZ and the Flexofold prop is likewise very similar to CZ's Varifold. I added a few extra columns to look at performance relativities. You can see the difference in speed at given revs c.f CZ is pretty consistent ie 0.2 kts less, due to the shorter waterline. You can also note the fuel consumptions, 2.0 l @1800, 2.8 L at 2000, so resistance starting to build there, but indicating the sort of no's I see with CZ. The rule of thumb for displacement vessels is that for every 1 kt increase in speed your fuel consumption will double. This table reflects the rule.

I used to sail on a Halberg Rassey in the UK. Think it was 42ft, centre cockpit and all of that. Very comfortable. Didn't pay attention to the type of engine (wasn't my boat, obviously, can't afford one of them...)
We will cruise at 7 knts when the bum is clean, at somewhere around 2,400, maybe 2,300. Waterline is 10.3 m. After sizing the new engine, gearbox ratio and prop, I can hit my target boat speed at full revs, but only with a clean bum. Think it was 7.9 knts. I was very pleased I managed to work that all out correctly. I read Dave Bear's Propeller Handbook cover to cover. Fascinating technical stuff to learn.
Noting we have a kiwiprop. They are good, but not as efficient as a fixed prop or some of these fancy bronze folders, like a 3 blade maxprop or varifold. Good for sailing but not as smooth when motoring. I did chuck our old fixed 3 blade back on once, and it made a noticeable difference. I think the kiwi is the same size to the fixed prop, but I've tweaked the pitch to optimise it. The 3 blade may be a tad less pitch than how I have the kiwi now.

Limped into a gassy yesterday and put 68lts into the 70lt tank, $170 later thank you.
