  1. Citric acid is great for cleaning stainless steel, copper and brass without damaging it, and actually creates a protective layer on copper alloys, effectively passivating them (excellent for spent rifle casings!) so is a great choice for heat exchangers and plumbing. On stainless it removes free iron which will help stainless stay stain free.

    Phosphoric eats iron oxide (rust) and converts it into a black protective layer, passivating steel or iron. I use it all the time on the farm and when cleaning machine parts.

    I just get concerned when there's dissimilar or unknown metals (like zinc or aluminum hiding somewhere) and parts are left for a while where you can't inspect them.

    I find white vinegar straight from the supermarket without dilution works just fine if given a few days to a week to work, and I've got some peace of mind that I'm not causing new problems while I'm gone. Seems to be good at cleaning leaky joker valves without needing further work and if it doesn't fix the problem the pipes are far less unpleasant to work on.

    Nor should the Harbour be closed at anytime of the gp. There should be a corridor that harbour uses can use,what about coming back from xmas cruise etcWouldnt be hard to have 100m corridor out from the wharves or shore side 100m lout from a line oss stanley pt to northern bridge pylon for those up under bridge.

    Then how would they charge thousands per spectator boat?

    (Seriously though I can see how that could be a problem with cheeky boaties just drifting along at a few knots, possibly spoiling the view for paid spectators or even causing race control issues if they leave the corridor)

    Summer might be starting this weekend, wish I was out there!

    Perfect weather for a sail around Kawau Bay and a swim to finish the day off. 

    Fish aren't biting though.... it looks a bit barren based on what we saw snorkeling the last few days, but that said we had a kingfish lurking under our tender this morning about as long at the inflatable is wide!

  4. Yep your water strainers will catch the rest; just keep an eye on them and probably plan to replace the fuel filters after a bit of running.

     

    (I'm assuming you've already drained that part of the system, of course)

  5. Is it possible to push air into the tank to force the water up the hose? All it takes is an air mattress inflator or tyre pump. You don't need much pressure so duct tape is all you need to seal mismatched hoses to holes.

     

    Edit: maybe try blowing back down the fuel pickup line?

     

  6. Well we made it out past titiri and it was looking pretty good, but it quickly became apparent that I'd be single handed the whole day. Pulled into Kawau and will probably just chill here for the week and hope conditions are better when we try again early Feb.

     

    BTW, it seems the weather station on Titiri has been out of action since new years day.

  7. I've been looking at https://weatherwatch.co.nz/maps-radars/wind/wind-forecast as it makes it easy to compare forecasts (and has the predictwind models, too).

    If more models start to agree on a break in the SW pattern I think we'll go for it and let the wind blow us out from Kawau on Monday or Tuesday, return to Kawau Fri/Sat.... either way, we'll be out on the water so it's not the end of the world if we don't make the barrier this time around.

    be flexible and head to Kawau Bay area, if the forecasts firm up do a mish to the Barrier, but don't pin any great expectations on it.

    Yeah that sounds like the best bet right now.

    Just me and the Mrs,  but myself I'm not too keen on sailing 8+ hours into big swells and high gusts, and I don't think the Mrs is going to handle rough seas too well, either.

     

    What forecast models do you think work well for the Hauraki? Metservice tend to underestimate wind I reckon. I try to look at various options, and as you said, if they don't agree then things are generally going to be unpredictable. 

  9. What do you guys reckon for next week? Different models are giving very different answers and while I'd love to have an easy run out to the Barrier on Monday, I'm not so keen on fighting it for the return leg on Friday....

    If I had to guess, I'd say more of the same SW 20kts gusting 25 until that high moves over and the wind eases up 10kts east maybe nor-east, but maybe I'm just being overly optimistic.

    Keen to hear your thoughts and preferred forecast models.

     

    Of course if it doesn't let up we'll just have to settle in at Kawau for the week, but I was hoping to finally get our little 25ft tracker over to the barrier this year and tick it off the sailing bucket list.

  10. I know electric is a big challenge for general boating, but for a little tender to get to and from the beach or a mooring there seems to be some half decent options.

    My little Honda 2.3 is starting to reach retirement and I was looking at the ePropulsion eLite. Has anyone tried one of these? What's your use case and how far do they go?

    Back on my old mooring, I was looking for a way to not have a smelly/oily outboard in the car and the eLite was a far more manageable 7kg to carry up and down the pier. However,  in my new mooring that's no longer the case as I can keep the outboard in a dinghy locker, so suddenly the old 4 stroke is actually looking more convienient as it's easier to refuel....

    Do these little outboards have the power and range for a small inflatable tender? Will I need to pay for the 12v charger, too?

  11. Well, it's been just over 24  months since posting this thread and I'm very pleased to say that I've moved my little tracker into a spot on the Weiti River.

    I'll save you all the rant, but the Westahaven poles literally have fist sized holes in them at the low water mark and westhaven has NO plan to fix this.  Yes, they have been snapping off, and yes, mine snapped off last year. They're just gambling that nobody gets hurt while they wait for everyone to leave. They even mucked us around (again) on the dinghy racks, with a big step down in security, services and parking. Absolutely disgusting behaviour from a Council controlled organisation. Be very careful navigating in that corner of the marina as I'm pretty certain there are snapped off poles below the water that they still haven't removed.

    Very glad to be out and very much enjoying the community/club vibe up at Weiti. I just hope one day Westhaven gets a new directive to cater to a wider range of Auckland boaties.

  12. So, just in time for christmas, my trusty honda BF2.3 has developed a serious oil leak from what appears to be the valve cover.  Does anyone have an old one of these kicking around suitable for parts?

    It seems that the last decade of use has caused a number of corrosion issues with bolts, carby bowl etc all needing replacement on an otherwise faultless little runner.

    Maybe opportunists, but salty tools from a boat, a solar panel and petrol containers? Sell for a fortune on marketplace, yeah right!

    This still have to get in a dinghy and row/motor out there for what is really an oddball and not very valuable collection of boat gear. Yes we know to replace new is hundreds but second hand its worth very little. Why didnt they break into the cabin or go for the electronics etc, Id say they went for the solar panel and the other stuff was just there so they took it. 

    If these individuals had any intelligence they'd not be mucking around flogging gear off boats to sell for next to nothing online.

    The reality is they don't care what damage they do nor what value is destroyed by their antics. 

    I'm sure half of what they take ends up dumped on a kerbside anyway

    Found in Leigh now

    And now it's gone? seems they misplaced it.....

    https://www.rnz.co.nz/news/national/519854/invasive-seaweed-caulerpa-proves-elusive-for-divers

    A team of divers is in the water this week hoping to destroy the first patch of the invasive seaweed caulerpa found near mainland Auckland - but first they have to find it.

    A roughly one square metre patch of exotic caulerpa was found in Leigh's Omaha Cove, north of Auckland, by divers carrying out routine surveillance on 7 June.

    The fast-growing weed, often described as the world's worst invasive marine pest, is already well established at Aotea Great Barrier with other infestations around the Hauraki Gulf, the Bay of Islands and the Coromandel Peninsula.

    However, when a different dive team went back to Omaha Cove, the patch of caulerpa seemed to have gone AWOL.

    Liz Brooks, of Auckland Council, said divers returned to the water on 12 June to treat the patch, but could not locate the caulerpa despite having GPS coordinates of the initial find.

    Divers resumed their search this week and, once the weed was located, would cover it with mats and dose it with chlorine.

    That technique had proven effective for treating small areas of caulerpa in the past.

    "Divers will also continue to look for any other patches of exotic caulerpa, in addition to checking for other marine biosecurity pest presence in these areas," Brooks said.

    If an engine alarm goes off, isn't it a normal instant reaction for virtually any skipper (let alone an experienced one)

    it would seem that dangerous incompetence is a legal defence strategy these days

    If Auckland then there's where's the course? ...........Up and down the habour (Westhaven to Orarkei)? Whilst it's a convenient Wednesday night course it's still a crap course on what we have to offer further out in the Gulf,

     

    That was the  idea until council stuffed it up.... it would've been ideal for general spectators
