Weiti are struggling to house boats at the moment.
Members who wish to have a mooring go on a waiting list, whilst you are on that list you go on sublets which means if the holder of a permanent mooring goes away for a decent period, or goes on the hard, or sells their boat but is replacing it and continues to pay their full mooring fees - the club can sublet that mooring out to someone on the waiting list (draft and length permitting of course).
Downside for people on sublets is they don't have access to the dinghy locker and often have to relocate at reasonably short notice. Kind of like Musical Chairs 😅

So after a week of fiddling, testing and measuring it would appear I have excorised the demons from my freezer.
Wound txv in a couple of turns and back out to original position half a turn per day.
Been keeping a bunch of bottles of frozen water and hello fresh freezer packs in there and running motor freezer every day at random times, and happy to report its worked every day.
Not an easy task when not on a marina!
My jubilation at possibly saving $1000 or so was short lived this morning when I found that the knead-it repair I did on the exhaust elbow last year was indeed temporary, the raw water pump has developed a drip and the hot water cylinder has a puddle of bright red yanmar engine coolant under it.
Amazing what you pick up when sitting around waiting to measure freezer Temps every day!

Thanks Psyche, yes had a read of those earlier. As always, well written and easy to follow.
Have a couple of questions, re: sight glass being full - does this mean solid liquid right up to the inside of the glass itself when running, or full to the orifice inside the unit? I ask because mine has a conical dish above the orifice to refrigerant pipe with the word 'Full' on the tapered face. When running the liquid in the line rushes past only occasionally wetting the very bottom of this dish, never getting up to wet the bottom of the glass itself.
Second question, in Matts article he describes controlling the distance of frosting from compressor on the return line by opening and closing the adjuster on the TXV. Closing the valve moves the frost further away or 'back up the line' from compressor. This 'closing of the valve' would mean winding the adjuster screw "in" or clockwise yes?
I ask as for some reason I have in my head that making the gap in the TXV smaller would mean that the refrigerant would compress 'harder' to get through the gap and therefore come out the other side with more energy, thereby cooling more. I guess like squeezing the end of a garden hose to spray your car down.
Interesting stuff, not quite as frightening as it first appears!

IMO It sounds like you need to get a professional in. It's a $50k fine in NZ to intentionally release SGGs into the atmosphere. And you're going to need special expensive equipment to replace the txv anyway and regas the system.
Don't fret - I'm not about to start undoing any pipes or anything - not a refrigeration technician by a long shot but also not an idiot!
Just wanting to learn as much as possible about what is in the boat and hopefully make a more accurate diagnosis of what is causing the issue.
If tapping or adjusting the txv (in and out but finishing back at same point as it started at) and checking location of bulb plus maybe exercising it a bit (plunging it alternately between cups of ice and hot water) doesn't cure it I'll get it replaced and regassed.

Looks like I have some insulation mining in my future 😅
What would be the best pipe for the thermostat bulb to be attached to for efficient temperature control - txv exit or tank exit?

Spring is your thermostat
What's the purpose of the big springy coil attached to the txv?

Hi Matt
Yes the compressor works as should, and the sight glass behaves as described (fills up.and bubbles clear). It has R154 in it, the Engine is only 700hrs old and it would appear Compressor is same vintage. Once I realized we had an issue I could tell within a minute of firing the thing up if Mr Cool was in the house by touching the outlet pipe from Fridge back to compressor. It would very quickly get icy (but not at compressor end so not concerned about slugging).
It would appear that something is randomly deciding whether or not it's going to let things happen, a stuck TXV sounds like a lovely culprit... I took the panel off and found valve, buried in the insulation. I'm picking the spring above doesn't actually need to 'spring' as it looks pretty glued in place!

The Engine driven compressor/plate/brine freezer on our 1020 is hell bent on sending me to the looney bin, and possibly divorce court.
Its a standard factory fitted interior with a top loading stainless lined freezer in chart table surrounded on all 4 sides by the brine tank and front opening fridge utilizing the back of 1 freezer wall.
Load boat up for Bay of Islands trip, go down and fire it up, Load freezer, flick compressor on and within 5 mins there's a healthy frozen line moving it's way up the walls of the freezer. Running it for 1 hour has the whole thing chilled down super well and off you go enjoying cold beers from the fridge safe in the knowledge your steaks will still be frozen days later.
Day 2, fire boat up to motor out of Tut's and head up the coast. Flick the compressor on for a cool down 'top up'. turn off after an hour and notice that it hasn't really appeared to Ice up like the day before. Doesn't concern you, maybe some kind of thermostat thing where system is telling you "hey don't worry - still all frozen in here"
Day 3, motor out of Paradise Bay towards Russel with fridge on. Hmmmm - this thing ain't working. Compressor clutch clicks in, engine revs drop a bit but nothing flowing through sight glass and return line not freezing up. Start to panic, food at the top has defrosted. Phone and ask wife to bring the 12v Dometic unit up from home when she meets you. Make plans to empty freezer and divide perishables between friends boats freezers. Revise meal plan to eat top layer of food first.
That afternoon, after picking family up from wharf you try it again and boom! - Elvis is back in the building. Freezing faster than Kim dot Coms assets. Must have been a glitch in the matrix. Yeehah, cancel plans to shorten family holiday and move on with your life.... except.... Day 4, Elvis is Dead on the Toilet. Resume panic stage... then repeat above steps for remaining 10 days of your trip.
That was our new years trip. Since then we have done a couple of overnight trips with pretty much the same result. Fantastic for a day trip, but no good for multiple days. This Labour weekend was the same - Froze down Friday, didn't work Saturday or Sunday, fired back into life Monday on the way home.
Anyone with experience of this phenom?
Boats been back in the water for a year following a decent refit. Had never used it before then, the only modification to fridge system I undertook was remaking engine mount/compressor bracket to relocate compressor to the space under quarter berth instead of hanging through wall of engine compartment and burning a hole in the bedding. Hoses were never disconnected in this process but the compressor orientation was altered perhaps 90 degrees - are they fussy about that?
It's been suggested it could be a jammed TXV, could this be the case or is it simply adjusted to only work above a temperature that's not low enough for the freezers purpose?
Frustrating that when it works it's amazing - but only works when it wants to.
Fire away!

Tony's was the first 930 I ever crewed on, and I ended up buying one due to it.
Judging from the Swiss cheese bulkhead and missing shelves visible in the background of his interview I'd wager there's less of her there than when I raced on her though!

The clarity of that water at such a depth is amazing.

Great stuff!
Well done all involved

Great photos! What bay is the first one?
All the same place, Deep Water Cove in B.O.I.
We were tucked up in North East Corner in about 4m but looked like 1.5😅

8 months on from purchase and we made it back up to the BOI.
Even knocked most of the things off the wife's list including pressure hot water and shower!
What a game changer the extra meter on waterline is. I spent 14 days in total on her, wife and kids 10, even had a friend and her kids stay for 2 days and nights (7POB), came home with still frozen food in bottom of freezer and water in tanks. I'll call that a win!

BOI wasn't super packed. Headed up boxing day. Only a couple of windy(ish) nights. Snorkeling at Deep Water Cove was a highlight.
Currently motoring solo off Whangaruru straight into Southerly... waiting for the Easterly which I can see approaching. Might get a bit breezy!

I remember coming into Tairua once on our family's Moonraker 23 trailer sailer, we had holidayed there for years in a caravan and had a 16ft Pelin Aquarius fizz boat, heaps of bar crossings with no issues (if not a bit sketchy for an overthinking kid).
But the old man had decided Waterborne holidays were the next thing.
I'll never forget it... outgoing tide, heaping up breakers hovering over the transom while the long shaft 8hp motor struggled to move us over ground, survived half a dozen dumpers in the cockpit (fortunately shutters in) before dad decided maybe we should extricate ourselves from the situation, he threw the tiller to port and by this time we were so close to the Rocks on the Motu to the right a guy who was fishing off the rocks fended us off NZ by lifting his rod up and pushing our pulpit away from his face 😀

You of all people should be familiar with it?

Anyone smarter than me or with a subscription to a decent weather predictor care to make a call on the boxing day weather?
Hoping to singlehanded mission the 1020 up to B.O.I.
From as far out as I can look it appears a large high may be approaching meaning some south in the breeze but we are talking 11 days out! 🤣

Looking at a mates motor yesterday, leaking a fair bit of diesel from what appears to be the threads on top of injectors.
They seem Uber tight, so I'm assuming they have some kind of olive/crush washer in the stack that you can replace?
Any leads on where to get such items? (alternatives to Ovlov welcomed!)
Cheers

Last year I was anchored in Oke Bay swimming on the boat and a pod of dolphins came in and frolicked for a good 30 mins close to shore. Apparently since boats have been banned from chasing them they have come looking for interaction .
2 days later, same spot I was in the water again and 3 Orca came in and checked us all out. One swam under me twice while I held the anchor rode. First he looked at me with his right eye, then spun around and looked with his left. I'm a pretty confident sort of guy but I still made a hash of 'nonchalantly' meandering around to the ladder and getting the hell out of the water 😅
They've been around for a lot longer than us and will be here long after we're gone

Rob from Gulf Harbour rigging replaced all standing rigging for us, new chainplates, windows, mast wiring done.
Now back in the water it's a push to get all the plumbing/cooking/nav systems installed and operational before Xmas... no popping the champagne cork just yet!
Fortunately the mechanicals are pretty low hour and the fridge freezer works like a mad thing, so I can concentrate on niceties now.

NE / NNE winds at Xmas? What's the plan to head north?

I'm seeing a bloody decent send up the coast from Xmas day eve through to midnight Boxing day.
Hack sawing up my old 930 spinnaker pole to make a prod for the 1020 as I type 🤣
